Fertilizer Numbers – What do the number on fertiliser label mean value ? Why are they crucial ?
Here ’s the deal . fecundate plants comes at a monetary value – in meter , in money and results !
To get the most from your “ works food ” dollar mark , keep clearly in nous why you are fertilizing .
Each fertilizer intersection has a definite purpose and the routine on the label tell the purpose .
The one you should use depends upon :
Did you conduct a soil test to find out its soil pH ? The test results tell you if any additional soil amendments are needed .
Do you wantquick action at law from the plant foodfor a short quick green gloss or a irksome - expiration military action over a longer meter period ?
These are the thing to consider in choose a fertilizer but what do the number on plant food mean ?
A wrong pick is not only a waste of endeavor and money but can actuallybe worse than no fertilizer at all !
In this clause you ’ll learn :
3 Numbers On Fertilizers
To ensure good plant growth , they command :
Nitrogen is the most quick used up and , therefore , the one that must be replaced most often .
How To Read A Fertilizer Label
Every container or bag you buy on the grocery store will have a fertilizers label .
The recording label will have theN - P - K ratio . These tell buyers how much of the plant nutrient each bag contains .
The NPK acronym support for Nitrogen , Phosphorus and Potassium . These are often bring up to as “ macro - nutrients . ”
The label also provides other information on the make - up and use of the blend .
For example :
What are the fertilizers blends primary economic consumption ?
The “Complete Fertilizer” – Different Plants Use Specific Fertilizers
A so - called “ complete fertilizers ” is one which contains all three of these N - phosphorus - K nutrients .
Meaning a 12 - 4 - 8 fertilizer would have 12N-4P-8K.
Since different types of works involve different amounts of each food – no one fertilizer is a “ COMPLETE ALL - PURPOSE FERTILIZER ” for all plants .
The good grass fertilizers may produce a thriving lawns but using the same lawn fertilizer as atomato fertilizer will causethe tomatoes to grow only leafage .
The one that get to the wisteria bloom may do the caladium to wear itself out producing unwanted prime instead of fancy leave-taking .
The correct alternative for the fragrant - leave geranium plant whose blooms are unimportant is wrong for the zonary geranium from which you expect flower .
If you are looking for leafy growth and green leaves with plants such as dough , ivy , orgrass , select ahigh nitrogen fertilizer .
If you are arise fruit or flower plants – tomatoes , roses , strawberries , candytuft ( Iberis ) – use one eminent in phosphorous acid .
For root crops such as potatoes , carrots , and beet , search for a high-pitched potassium hydroxide content .

Two Groups – Chemical and Organic Plant Food
plant food are divided into two groups – chemical and constitutive fertilizers . Each group has advantages and disadvantages .
Chemical Fertilizers
Chemical fertiliser sometimes called celluloid fertilizers are quick performing and chintzy . In gain , they are made according to a definite formula .
When you corrupt one you acknowledge exactly the percentage of nitrogen , phosphoric back breaker , and potash in each 50 - pound bag and whether or not it contains trace minerals .
Under the trade wind name on each bag or bottle will be three numbers , for instance , 5 - 10 - 5 .
The first numeral indicates the percentage of atomic number 7 , the second act of phosphate acid , and the third telephone number of caustic potash .
Thus , you could easy select fertilizers that is high-pitched in whatever your flora particularly needs .
For example , you may select ratios with plant food numbers of :
A general all - purpose mixture is 5 - 10 - 5 . The root of a chemical substance is usually sand .
Chemical applications should be done strictly according to the direction on the label .
An overdose of chemical fertiliser canburn a lawn or green leaf on a plantor even do them to become flat .
A teacup defend about one - half a pound of fertilizers . Always pee fertiliser in thoroughly , and never lease it refer the foliage or stems .
Commercial fertilizers use up the hommos in the soil . They are short last and often leave a balance in the grease that stimulate an acid or alkali reaction .
Therefore , you should not apply the same chemical variety on the soil class after year . You must also add large measure of hummus to replace that which is lost .
Organic Fertilizer
Organic works foodsare slow act , long permanent , and build up the grunge in the garden over a tenacious period of time .
Because of their slow action at law , they may be used more freely with less peril of overfertilizing .
For instance , several constituent lawn fertiliser include fish photographic emulsion ,
Organic fertilizers high in nitrogenare :
The bestorganic sources of phosphoric acidare :
constitutional potashis found in :
The value of the “ nutrient ” in constituent plant food varies make it difficult to mark them as precisely as semisynthetic fertilizers .
constitutive salmagundi are packaged , but with the rough nutrient percentage on the traveling bag .
Any option can be overuse , however . Every plant has a saturation pointedness beyond which more solid food is bad .
Plants seem to be affected by too much solid food just as human organism are by too rich a dieting .
Remember , too , that some plant such as Nasturtiums and certain herb actually choose a rather poor soil .
A adept rule of pollex in choosing between a chemical and an organic option is this :
If you are primarily interested in the crop that twelvemonth – yearly peak , tomatoes , etc . – employ chemical .
If you are more interested in long - terminus increase as in the case of trees and shrubs , long - hold up bulb , and perennials , then use organic .
