Some of the research papers related to soil science and agronomy have given importance to nutrient uptake. Further, It is possible to estimate the nutrient balance sheet using nutrient removal or uptake. We have to explore the possibility of using nutrient uptake data for arriving nutrient requirement of the plant. Some of the experts in the researchgate can give more on this particular aspect.
Well,
According to the ratio of Redfield Molarity (C106: N16: P1), and the percentage of phosphorus nutrients in the lakes with the lowest ratio preparation for plant needs. The ratio of nitrogen to phosphorus in the plant tissue ranges from 1:10 to 1: 1.
Sincerely
it is not a good indicator,
with gradual adding of a sequential concentrations from deficiency to moderate and excessive ranges you can estimate the need of your plants, if there is no data in the literature!
