In the chicken manure business, when somebody gives you an analysis with three numbers, what does this mean?
For example, you call us and we tell you that our analysis is 5 – 4 – 2, what does this mean?
Typically, an NP & K analysis is delivered as three numbers. It could be 5 – 4 – 2, it could be 4 – 3 – 2, or anything.
These numbers are percentages of one ton of chicken manure.
5% Nitrogen = 100 lbs of Nitrogen per ton.
4% Phosphorus = 80 lbs per ton.
2% Potassium = 40 lbs per ton.
