Mass flow by a crop of tomatoes

Reference no: EM13184202

Soil Fertility Question:Calculate the amount of N, P and K reaching the roots by diffusion and mass flow by a crop of tomatoes given the following:

Fresh yield of fruit = 100 tonnes /ha
Moisture content of fruit = 85 %
Harvest index = 65%
Transpiration ratio = 300
[N, P and K] in plant = 2, 0.2 and 2.5% respectively
Average [N, P and K] in soil solution = 50, 0.8 and 25 mg/L respectively
Assume N, P and K interception by roots to be 2, 0.4 and 1.5% respectively of total uptake by crop.
