16% Nitrogen 20% Phosphorous 0% Potash.
0-0-60 fertilizer is straight Potassium or commonly referred to as "potash"
The three numbers on a bag of fertilizer indicate the percentage of nitrogen, phosphorus, and potassium available. So in the case of 0,0,60 fertilizer, there is 60% potassium available with no nitrogen & phosphorus.
It usually refers to the ratio of nitrogen (N), phosphorous (P) and potassium (K) in the fertilizer. So 10-0-0 means that there is no phosphorous or potassium, only 10 parts nitrogen per 100 parts fertilizer.
34-0-0
16-32-16 refers to 16% nitrogen 32% phosphate and 16% potash. It is used for plant growth.
A nitrogen fertilizer is what is used to fertilize pecan trees (Carya illinoiensis).Specifically, ammonium nitrate is an effective, reasonably priced nitrogen fertilizer for pecan trees. It is sold in packages marked 33-0-0 for 33% weight of nitrogen and 0% each of phosphorus and potassium. Another effective, reasonably priced nitrogen fertilizer is ammonium sulfate (21-0-0), at 21% nitrogen.
A balanced, general fertilizer is the best fertilizer for yellow chokecherry. The shrub or small tree in question (Prunus virginiana) needs loamy, well-drained soil with pH (power of hydrogen) ranges between 5.0 and 8.0. It generally requires fertilization, such as by a 16-16-16 NPK (nitrogen, phosphorus, potassium) fertilizer in the spring, only if soil testing and analysis suggest nutrient deficiencies.
16 subtracting from 0 = 16
0 x -16 = 0
Mainly by organic/natural vs. inorganic/chemical/man-made, although they are also classified by nutrient content. For example, a commonly available man-made garden fertilizer might say "16-16-16-4S" on the label. Using the common nomenclature in the fertilizer industry, this means that it contains 16% nitrogen, 16% phophorus, 16% potassium, and 4% sulfur.
