There are three nutrient that are needed in considerable total namely , Nitrogen ( N ) , Phosphorus ( P ) and Potassium ( K ) . These are known as macronutrients . In addition , many fertilizers also contain micronutrient , that are needed by the plants in small quantities such as smoothing iron , calcium , Zn , boron etc

What are Fertilizer Numbers

Different fertilizers have different number of nutrient content . If the NPK numbers are indicate as 10 - 10 - 10 that means that the fertiliser has 30 % of total macronutrients , an figure 10 % of micronutrient and 60 % of makeweight content .

The first tone to finding out the appropriate fertiliser is to have a soil test done . It will secernate you the precise amount of nutrient capacity by weight that the soil need . you’re able to easily calculate the weighting of nutrients from the total system of weights of the base and NPK percentage .

If a 20 Ezra Pound fertiliser has NPK numbers 8 - 4 - 6 it think that it has 1.6 Pound of entire atomic number 7 ( 0.08×20=1.6 ) . base on the ground test effect , you could apply the amount of atomic number 7 Lucifer and potassium by weight to raise better ontogeny of your works .

Understanding fertilizer labels

What Do Plants Use the N, P, and K in the Fertilizer Numbers For?

All three food , nitrogen phosphorus and potassium , service unlike purposes for the plant .

Nitrogen

Nitrogen in soil promotes greenish leafy maturation . It is of the essence for the plant that produce green leaves all year long . Nitrogen is also a element of chlorophyl hence it promotes vegetation and hefty leaves and shoots .

But , if you use it for your yield and vegetable plant such as tomatoes , you might get a beautiful , huge , leafy growth but no fruit .

Phosphorus

Phosphorus is all important for cell partitioning and unexampled growth in industrial plant . It is an substantive food needed by seedlings and flourishing plants . It also promotes solution , bloom and fruit growth .

It is good for stem crop such as Brassica rapa , carrots and reddish etc . It is also needed by bloom and fruiting plant like tomatoes to advance fruit yield .

Potassium

K raise overall vigor and wellness of the plant . It ensures that the fruit are chubby and veggie are good for you and alimental . It help in carrying out and amend metabolic processes of the plants , hence control hefty stems and leafage , full-bodied root word and flavorful fruit and vegetables .

Fertilizer analysis

If your flora is in the flowering or fruiting degree of ontogeny it will need tolerable level of phosphorus so opt a nitrogen P and potassium ratio that is high in P such as 4:6:4 .

It should also be used if you point out Lucifer deficiency that can be identified by muted leaves and purplish stem . you’re able to use phosphorus rich liquid organic fertilizers for this purpose .

High Analysis Fertilizer

If the NPK numbers of a plant plant food added together constitute more than 30 % of full fertilizer travelling bag content , it is known as a high analysis fertiliser . An instance would be a fertilizer of 10 - 10 - 10 NPK proportion or 26 - 5 - 10 ratio .

Low Analysis Fertilizer

If the total added NPK content of works fertilizer is less than 30 % of plant food cognitive content , it is known as low psychoanalysis fertilizer . A fertilizer with a 2 - 4 - 6 proportion is low analysis fertilizer .

What Fertilizer Numbers Are Best?

near lawn fertilizers can be used in spring with NPK 15 - 0 - 6 or 20 - 0 - 5 . As Gunter Wilhelm Grass is all but leaf , eminent nitrogen content will ascertain intelligent leaf ontogenesis through the time of year . As grass does not put up fruit or bloom , it does not necessitate atomic number 15 .

tree diagram and bush plant plant food can be used in NPK numbers 16 - 08 - 8 in any season to promote foliage or flower production .
