Hi I am new grower. But I just need to find an answer.
When you wana decide on what portion of what organics you wana have in your soil how do you calculate the overal NPK value of that mix? I know I can just multiple the NPK value by its portion and add em all up. But how do I factor in the release rate of nuts?
EX. we have 2 portion blood meal ( 14-0-0 ) plus 1 portion hard rock phosphate ( 0-33-0 ) plus 1 portion grapefruit skin ash ( 0-3-30 ) what's the overal npk of the mix?
Rock phosphate has a very slow release rate of P. takes up to 10 years till u need to re apply
Blood meal has a fast to medium release rate of N. takes 4-12 month depending on the crop, condition, etc
Grapefruit skin ash like most skin ashes ( banana, cucumber, etc ) it's very very water soluble so has a very very fast rate of nutrition release. Almost instant.
So can anyone clear this for me and solve the Example ?
