Basics About Organic Fertilizers

If you understand this basic principle, you will learn a lot…
Question was being asked about the utilization of some branded fertilizers i.e.
Bone Meal.
Blood Meal.
Fish Fertilizer or Fish Meal.
Epsom Salt.
Neem Cake.
Mustard Cake.
Let me add some more like;
Banana Peel.
Egg Shells.
Apple Leaves.
Coffee.
Peanut Shells.
Peanut Shell (Ash).
Tea Leaves (Chay ki Patti).
Tobacco Leaves (Tambaaqu)
Wood Ash.
It has already been discussed that the word “Fertilizer” revolves around two basic Types;
Macro Fertilizer
Micro Fertilizer
Macro fertilizer revolves around three Basic Constituents; i.e. Nitrogen 👎, Phosphorus (P) and Potassium (K). When we combine NPK, it shows N:P:K. People misunderstood about the NPK and assumes that whenever we write or discuss NPK, they believe, the chemical fertilizer is being discussed. No, it is not. NPK shows the tendency / miqdaaar of Nitrogen, Phosphorus and Potassium in any compound. No fertilizer can be Macro Fertilizer, if it does not posses NPK at certain ratio, even sometimes, any one or two may be so minimum that is almost absent but their presence is in 0.1% or 0.01% even.
Now coming back to the topic;
Let me tell you what organic compounds have the ratio of NPK.
Bone Meal. 3:15:0
(It shoes it has almost zero level potassium but heavy amount of phosphorus.)
Blood Meal. 12:0:0
(It indicates that blood meal contains heavy amount of Nitrogen but potassium & phosphorus are either absent or in very limited quantity even not be noticed.)
Fish Fertilizer or Fish Meal. 10:2:2
(Good amount of Nitrogen and small amount of potassium & phosphorus.)
Neem Cake. 4:1:2
(Small quantity of Nitrogen present in Neem Cake along with potassium & phosphorus.)
Mustard Cake. 4:1:1
(Likewise the case with Neem Cake.)
Banana Peel. 0:3:42
Banana Stalk 0:3:50
(Very high quantity of Phosphorus in banana peel & stalk).
Coffee. 2:0:0
Peanut Shells. 1:0:0
Peanut Shell (Ash). 0:1:7
Tea Leaves (Chay ki Patti). 4:0:0
Tobacco Leaves (Tambaaqu) 4:1:6
Wood Ash. 0:1:2
I deliberately left Epsom Salt and Egg Shells, as they cannot be consider in Macro Fertilizers. Do you know, Why? Because they do not contain Nitrogen, Phosphorus and Potassium (0:0:0), three of the main constituents are absent. They only contain Calcium which is not a MACRO FERTLIZER but it is in the list of MICROS FERTLIZERS. Same is the case with Epsom Salt (0:0:0), it is not considered as Macro Fertilizer but it is included in the list of Macro Fertilizer, it contains Magnesium and Sulfur in good quantity.
