I involve 20-20-20 fertilizer for my coffee plants, is at hand an alternative ?
Answers: An natural general fertiliser would be 'fish blood and bone'.
If you enjoy a wormery, the 'worm wee,' diluted is perfect.
In the USA, the 20-20-20 stands for the concentration of N, P2O5, and K2O, surrounded by the fertilizer. In this case, it scheme the fertilizer is 20% Nitrogen, 20% P2O5 (phosphorus) and 20% K2O (Potassium). Consequently, you should be told to be putting a known rate (weight) per plant or per component area (acre, 1000 sq. ft. etc.). So if you be told to put on 1 pound of 20-20-20, then 2.5 pounds of an 8-8-8 would furnish you the same results.
Along that same lines, commercially available life fertilizer should have a N-P2O5-K2O content on the sticky label, thus the amount adjusted suitably. As organic fertilizers are disgracefully poorly balanced you will over apply something to draw together the requirements of something else. This is usually acceptable surrounded by the first few fertilizer applications, but eventually the overapplied material (usually phosphorus) will get threshold levels and become a potential polluntant.
I would check near your local garden center. I use that formula for my plants under lights and that's where on earth I find it.
Good Luck!
