The three primary nutrients essential for plants are the NPK – Nitrogen, Phosphorous and Potassium. Nitrogen (N) is largely responsible for the growth of leaves on the plant. Phosphorus (P) is largely responsible for root growth and flower and fruit development. Potassium (K) is a nutrient that helps regulate important physiological processes or the functional processes in a plant.
Having said that, now let’s look into what is Rock Phosphate and the difference between Rock Phosphate fertilizer and Bone meal fertilizer.
Rock phosphate, also called phosphorite, is a natural mineral fertilizer obtained by mining from sedimentary clay deposits and rocks that contain phosphorus. Rock phosphate is a long-standing or slow release best organic fertilizer for adding phosphorus to your vegetable garden.
Both Rock Phosphate and Bone Meal are good sources of organic phosphorous for home gardeners. Bone meal is mainly used as a short term phosphorous supply and rock phosphate as a long term phosphorous supply, as it’s slower to break down plus it’s a non leachable source of phosphorous and calcium.
Now let’s look into 5 important benefits of using organic rock phosphate in gardening and How much and how to use it:
- STRONG ROOT SYSTEM: Rock phosphate promotes the development of strong roots throughout the growing stage of a plant and makes your plant healthy and high yielding by accelerating plant maturity.
- RESISTANCE TO PEST ATTACKS: a strong root system and a healthier plant means a plant highly resistant to pest attacks. Applying phosphorous at early growth stage of a plant will confer a great immune system and help resist pests.
- FLOWERING PLANTS: Any flowering perennial plant like rose and hibiscus love rock phosphate as it helps them develop more buds and larger sized flowers.
- VEGETABLES AND FRUITS: Strong roots, healthy immune plant and more buds means more vegetables and fruits. One or two applications of rock phosphate early in the growth stage is important to achieve this.
- Improves Soil Structure and water holding capacity. Rock phosphate is in Powdered form and hence can be mixed with soil and proves very beneficial while you prepare the potting soil before planting.
- EARTHWORMS and Beneficial microbes in soil are not harmed and infact they love it.
- DOSAGE and How to Apply: Best way is to mix the rock phosphate powder in your potting mix along with other stuff like compost, cocopeat or peat moss and others. This is because for proper phosphorous uptake by plants, the soil PH has to be slightly acidic and and adding compost like decomposed cowdung or vermicompost will help achieve this task. You can watch a detailed video on making the best potting soil here.
Well, Now, How to use Rock phosphate in potted plants and plants grown in ground or raised beds.
First of all loosen the soil around the plant by raking or tilling the top layer. For Potted Plants start with 1 teaspoon per container and then add 1 tablespoon after 15 days. For ground plants or raised beds start with 1 tablespoon per plant, preferably in its growing stage and then two tables spoons after 15 days. And this one time application will help your plant throughout its stages of growth till flowering and fruiting.
Before we start displaying the various leaf patterns, you must understand some basics in order to diagnose this problem of nutrient deficiencies in plants and start the right treatment to save your plants. Because directly jumping in to adding too many supplements can burn or kill your plant.
Plant nutrients fall into 2 categories: macronutrients and micronutrients. Macronutrients are those elements that are needed in relatively large amounts. They include the three major ones – nitrogen, phosphorous, potassium, that’s NPK and also sulfur, calcium and magnesium. Micronutrients are those elements that plants need in very small amounts, like iron, boron, manganese, zinc, copper and molybdenum.
Most of the times, except in container gardening, these nutrients may be present in the soil. So before adding supplements you have to diagnose your condition by checking these 3 problems or factors:
- The problem may be with the roots – not able to absorb or uptake these nutrients. This can be due to root disease or improper watering. Because these nutrients are taken up by the roots only in the presence of moisture.
- Soil PH may not be right. Most plants need a PH of around 6.0 for proper absorption of nutrients by the roots. Having this little PH meter will certainly help you rectify this problem. You can find related posts on altering soil PH.
- Pest attacks which can sometimes resemble the patterns of nutrient deficiencies, especially the sucking pests like aphids. Make sure you thoroughly examine your plants.
Now having said that, let’s jump
into identifying the various leaf patterns of discoloration and distortion and
diagnose this problem. But always Keep in mind that each plant variety is
different and may display different symptoms. And also the damaged leaves may not come back
to normal after treatment but the new leaves will certainly come out healthy
and lush after treatment.
Let’s start with:
- Nitrogen Deficiency: you will notice complete yellowing of the older leaves generally at the bottom of plants. The younger leaves are often healthy and green. This is because, nitrogen is a mobile nutrient which moves up from the lower parts of the plant to the growing ends as a compensatory mechanism and hence the older leaves donate nitrogen and show complete yellowing including the veins and the entire leaf surface. The solution to this is simply adding a good nitrogen rich compost like decomposed cow dung or horse dung. But before adding, please rule out the problems of improper watering and soil PH that we already discussed.
- Calcium Deficiency: Here the new leaves are affected and may show yellowing, distortion and even burnt tips due to necrosis or death of the tip tissues. Blossom End Rot (BER) seen in tomatoes and squashes is the best example of this. We have discussed this problem and treatment in detail in my previous post.
- Magnesium Deficiency: Magnesium is also a mobile nutrient and hence The older leaves first turn yellow at the edges and surface – called interveinal chlorosis, meaning yellowing between the leaf veins. The veins as you can see, stay green, giving the leaf a marbled appearance. Remember, Magnesium is the central most atom in the chlorophyll molecule which imparts green colour to leaf. Foliar Spraying or watering the plant with 1 teaspoon Epsom salt per litre of water will give great results.
- Iron Deficiency: Iron is an immobile nutrient and hence cannot be carried upto the younger leaves from older leaves for compensation. So the leaf yellowing is first evident at the tips or the younger leaves. The pattern is similar to magnesium – the interveinal yellowing. This is actually a common pattern and most often due to alkaline soil ph which prevents proper absorption of iron by the roots. Hence its also called as lime induced chlorosis. The treatment for this is actually rectifying the soil ph to around 6, if its alkaline. Another method to bypass this problem is foliar spray of a micronutrient solution or compost tea.
- Phosphorous and Potassium Deficiencies: These are very much similar and plants show stunted growth plus leaf chlorosis like leaves turning darker or purplish. But this is difficult to identify and depends on the type of plant. Isolated Potassium deficiency usually exhibits yellowing starting at the tip or the margin of the leaf with the center being still green.
- Last but not the least, you must be aware of a condition called YELLOW VEIN CHLOROSIS. Here only the leaf veins turn yellow while the rest of the leaf shows normal green colour. This usually happens in winter or the dormancy period due to reduced nitrogen uptake by the roots from the soil in low temperatures.
Now the Universal Treatment Solutions for all these problems:
You have two options: First one is Making The Universal Cocktail Fertilizer mixture.
And the Second option is Vermicompost – which is rich is almost all micronutrients. Adding a handful every 15 days will keep your plants healthy and high yielding.
Well, Last year, we prepared a Mixed fertilizer containing both chemical and organic fertilizers with a detailed discussion and calculations on how to calculate the total NPK value. For beginners and those interested in these scientific calculations, please check out that article.
Now, we will quickly start the recipe for this well balanced organic mixed fertilizer, you can use for any plant in varying dosage to produce healthy growth, increase flowering and fruiting. We will also total the NPK value of by adding the NPK values of each of these components. For beginners – NPK means Nitrogen, Phosphorous and Potassium which are the Major nutrients required for plant growth.
- COW DUNG: Whatever animal
manure you are using, whether horse dung or cow dung or even goat dung. Note
down its NPK value. Here we are using decomposed
cow dung. So NPK is 3-2-1.
We are taking 2000 grams of cowdung powder.
- COMPOST (
Whether home made compost or VERMICOMPOST): In this recipe, we are adding
vermicompost which also contains many useful trace elements, so no need to add
that micronutrient powder containing trace elements. The NPK of vermicompost is
1.78, 0.77,0.94
We are taking 2000 grams of Vermicompost.
- BONE MEAL POWDER, you can also use any of the other meals like sterameal, fishmeal or bloodmeal. If you are a pure vegetarian, you can use soya bean meals as a substitute for bone meal. So the NPK for bonemeal is 3.5, 18, 0
Here, will add both bone steamed meal
powder as well as coarse bone meal chips powder mixed. This fine powder is just
to make it quicker for release of nutrients.
We are taking 1000 grams of Bone meal powder.
- we shall also add some optional stuff into this for additional fortification which also act as soil pesticides or pest repelling agents, particularly neem cake powder or Karanj powder. Then we will also add Mustard cake powder. We will discuss the benefits of each of these some other time.
Well, the first one Neem Cake Powder: NPK of neem powder is here:
N(Nitrogen 2.0% to 5.0%), P(Phosphorus 0.5% to 1.0%), K(Potassium 1.0% to 2.0%).
N – 2.0% to 5.0%, P – 0.5% to 1.0%, K – 1.0% to 2.0%
We are taking 1000 grams of Neem cake powder +
1000 gms Karanj Powder +
- of Mustard cake powder.
- Optionally, You can add 500 gms of Epsom Salt + 500 Grams of Micronutrient Powder to include those trace elements or micronutrients like Mn, zinc, Fe, boron and many others to safeguard our plants from any deficiencies. Also you can add more ingredients you wish to like used tea powder and any other stuff, because this is a one time mix and you offer this on a periodic basis and only once in 15 days or so and you add almost all organic nutrients and this reduces burden and saves you a lot of time, plus this become a quality mix!.
Nothing to worry about over dosage which is an issue with chemical fertilizers which can cause chemical burns. This is pure organic fertilizer with hardly any adverse effect on over dosage.
After Approximate Calculation, the Total NPK value of this fertilizer mix is:
22, 25,07
Have a look at this equation in the table:
| Ingredient | N | P | K |
| Cow Dung (3-2-1)-2000g | 6 | 4 | 2 |
| Vermicompost -2000g | 3.5 | 1.5 | 2 |
| Bone Meal -1000g | 3.5 | 18 | 0 |
| Neem, Mustard etc | 9 | 1.5 | 3 |
| TOTAL | 22 | 25 | 7 |
Then optionally you can perform a soil PH test and mix either woodash or lime to make your soil more alkaline if its too acidic and if your soil is too alkaline, you can add alum powder into this mix.
And one more important point from storage point of view: you might feel some moisture in this mixture due to some moist ingredients like vermicompost. You can either use completely dry ingredients before mixing or you can dry this mixture in sunlight and then store in air tight containers. It will not loose its NPK value much on drying. Remember to mix the ingredients thoroughly well for best results.
RECOMMEDED DOSE PER PLANT? Depending on the plant, you can use one tablespoon once every 15 days, specially for flowering plants and once in a month for other plants. Make sure you apply this after tilling or raking the top soil and apply around the plant – not directly on roots.
Check out the Best Pure Organic Pesticide Recipe.
We all know that plants need Major Primary Nutrients – that’s NPK – nitrogen phosphrous and potassium and also the Secondary or trace or micro nutrients like calcium, magnesium, sulfur, iron, boron, zinc, and so on. These are either derived from
- Natural sources – what we call Organic Fertilizers for example, Cow dung, vermicompost and many other stuff.
- Inorganic or Chemical Fertilizers like NPK crystals, DAP, Urea and so on.
Now I will list out the harmful negative effects or the dangers of Chemical fertilizers and Pesticides that you frequently use in farming or home gardening. You please make a decision yourself after watching this video till the end.
- Ground water
Pollution: Nitorgen fertilizers
break down into nitrates and can easily go down into the soil. These are
water-soluble and can accumulate in groundwater for decades. And if you keep
adding more nitrogen over the years, this will have a cumulative effect. Moreover,
these effects of chemical fertilizers are compounded when you mix or use a
chemical pesticide.
You know the Fertilizer Urea, produces ammonia and contributes to acid rain, groundwater contamination and ozone depletion due to release of nitrous oxide by denitrification process. If we continue this in future, this hazard may increase several fold in the coming decades.
And remember! studies have shown that Groundwater contamination has been linked to stomach cancer, goitre (thyroid enlargement), birth defects in babies, and also hypertension.
Also Aquatic life is also significantly affected by water pollution and fish and other water animals may not get adequate oxygen and they can die. These are called Dead zones.
- Air Pollution: Excessive use of chemical NPKs can release greenhouse gases such as carbon dioxide and nitrous oxide into the atmosphere. These can cause respiratory problems, cardiac disease, and many cancers. A special mention about the Blue Baby Syndrome, medically called methemoglobinemia occurs in infants and one cause of this problem is attributed to chemical over use and pollution where due to reduced oxygen in blood, the baby turns blue.
- Fertilizer Burn: You can burn your favourite plants and crops if used excessively – specially leaf burn and root burn. This fertilizer burn can even kill your favourite plant in addition to the hazards it causes to the environment. This fertilizer burn will not happen when you use organic or natural fertilizers.
- Depletion of Beneficial Organic Matter, beneficial Microbes and even Minerals from the Soil – that is reduced SOIL FERTILITY: This loss of organic matter can lead to soil acidification, soil compaction and hardening and other ill effects which makes it vulnerable to soil erosions. Researchers also say that depletion of minerals from the soil can also lead to low quality foods with lesser mineral and vitamin content.
- Though chemical fertilizers will help plants grow faster; plants will not be healthy and strong as plants grown in this manner do not have enough time to mature and develop a strong root system and strong stems, or good nutritious fruits and vegetables. And also they will be less likely to survive because they will be more susceptible to pests and diseases as they lack good immune system against pest attacks.
The Bottom Line: is There is a large threat to environment, animals and human health; chemical fertilizers will ultimately end up leaking into our water bodies; ponds, streams, ground water etc. and contaminate water supply as a result of which humans as well as animals may suffer numerous short term and long term hazardous chemical effects on their health.
So, Lets together take a pledge today to stop using these chemical fertilizers and pesticides and start using organic fertilizers and pesticides to keep our mother earth safe, for the present and for the future!!!
Healthy Soil = Healthy Plants
This means that you need to enrich your soil. Because most people are not making their own compost at home, they need to buy a fertilizer. Plant fertilizers purchased from the local nurseries often contain chemicals that may harm your plants. And also, these fertilizers can be a bit pricey. So why spend your hard earned money on these pricey fertilizers when you can make one yourself with just a little information?
So, How to Make Your Own Homemade Organic Fertilizers – Today I am gonna list out the Top 10 ways to enrich your soil.
Before that..
Making your own organic plant enriching formulas is really easy and fun. It should be noted that most people understand that the best way to get good garden soil is to use compost to amend the soil. Of course, that is true. Compost can be made at home out of leftover food scraps and lawn clippings, and so it is virtually cost-free.
While it may not be the most exciting of gardening topics, nothing is more important than having a basic understanding of fertilizer. All fertilizers are classified into two basic categories: chemical/synthetic – Inorganic and or natural/organic. I have discussed this in more depth in my previous video on NPK Crystals Fertilizer – the link is shown in description and also perhaps somewhere in a link towards top right corner of this video.
SO coming back to our List of Easy Household Fertilizers
There are actually quite a few common items found in your kitchen, and elsewhere around the house, that can be used as plant fertilizer.
The First in the List is – Aquarium Water
Water your plants with the aquarium water taken right out of the tank when cleaning it. Fresh water only please, do not use water from a salt water tank. The fish waste makes a grreat plant fertilizer.
Then Next – Bananas
Bananas are not only tasty and healthy for humans, but they also benefit many different plants. When planting roses, bury a banana (or just the peel) in the hole alongside the rose. As the rose grows, bury bananas or banana peels into the top layer of the soil – that’s called Top-soil. I have a separate video explaining what is Topsoil and subsoil in detail.
Anyways Both of these approaches will provide the much needed potassium that plants need for proper growth. So banana provide mainly potassium.
Cooking Water
Many different nutrients are released into the water that food is cooked in. Water that is used to boil potatoes, vegetables, eggs, and even pasta can be used as a fertilizer. Just remember to let the water cool before applying it to your soil.
Then very important one – the Egg Shells
Egg shells are rich in Calcium and contain about 1% nitrogen, about a half-percent phosphoric acid, and other trace elements that make them a practical fertilizer. Calcium is an essential plant nutrient which plays a fundamental part in cell manufacture and growth. Most roots must have some calcium at the growing tips to grow effectively. Plant growth removes large quantities of calcium from the soil, and calcium must be replenished, so this is an ideal way to “recycle” your egg shells. Simply crush them, powder them, and sprinkle them around your garden soil.
Epsom Salts
1 tablespoon of epsom salts can be combined with 1 gallon of water and put into a sprayer. Apply once a month, directly to the foliage for a quick dose of magnesium and sulfur.
Wood Ash (Like From Your Fireplace )
Ashes can be sprinkled onto your soil to supply potassium and calcium carbonate. Don’t use ash in areas where you are trying to maintain acid-loving plants – the ashes are alkaline and can increase alkalinity in the soil.
Green Tea
A weak solution of green tea can be used to water plants every four weeks. Use one teabag to 2 gallons of water.
Next interesting item is – Your Hair
Have you ever wondered, Hair is a good source of nitrogen. A good source for this hair is not only your hairbrush but also the local barbershop or beauty salon. Many of these establishments will save hair for your garden, if you ask them for it. But do not limit yourself to only human hair. Dog hair, horse hair, and cat hair also work very well.
Cow Dung or Horse Dung when dry and decomposed
- make an excellent fertilizer. It can be used as a soil amendment just by sprinkling it on top of the soil. Alternatively, it can be dissolved in water alone or combined with another organic fertilizer and applied.
Matches
The old fashioned easy strike matches are a great source of magnesium. To use this as a fertilizer, simply place the whole match in the hole with the plant, or soak the matches in water. The magnesium will dissolve into the water and make application easier.
Powdered Milk
Powdered milk is not only good for human consumption but also for plants. This source of calcium needs to be mixed in to the soil prior to planting. Since the milk is in powder form, it is ready for use by your plants.

There are broadly 2 types of Fertilizers.
Organic fertilizers include properly managed manure and compost.
Whereas, Inorganic fertilizers, also known as Artificial fertilizers, are formulated in appropriate concentrations and combinations supply three main nutrients: nitrogen, phosphorus and potassium that is, N, P and K, Hence they are named as NPK fertilizers.
The one Here, on left hand side, white colored salt is plain urea salt, which we are not going to use it for our home garden, because it has very high nitrogen content of above 80% which can burn the plant and roots, if used in higher quantity.
The other one, creamy yellowish crystals here are NPK fertilizer. We usually use percentages of 20 20 20 combination of NPK. Hence its also called as NPK 20-20-20.
N – the nitrogen, promotes leaf growth and forms proteins and chlorophyll. P – the phosphorus, contributes to root, flower and fruit development. K – the potassium, contributes to stem and root growth and the synthesis of proteins.
`
Careful fertilization with correct quantity is important because excess nutrients can be as detrimental. Fertilizer burn can occur when too much fertilizer is applied, resulting in drying out of the leaves and damage or even death of the plant.
So, without going into too many details, I will quickly show you what is required for home gardening.
The fertilizer you are seeing here is NPK 20-20-20. The 1 kilogram bag of this, costs about 250 to 300 Rupees. The link to purchase this in India is given in description of this video. You can also search or this NPK fertilizer at our website www.GKVK.IN .
Application of this fertilizer crystals is very easy and depends on the size of the pot. For Larger pots of 16 – 18 inch diameter, you can use 15 to 20 crystals, once, every 15 days.
For 12 to 14 inch pot diameter, you can use arounf 10 crystals every fortnightly. For smaller pots,
About 5 crystals should suffice.
If your plants are in ground soil, you can use little larger quantity without any issues.
Okay!, the easiest method is, Just throw them on the soil. They are water soluble. As you keep watering your plant, the NPK slowly dissolves in water and enters the soil and the roots slowy take up these elements as an when required.
