Answer 2

Answer:

On the average, one ton of grain along with straw of wheat, paddy, maize, and barley are likely to remove 33 kg of Nitrogen.

Explanation:

Nutrient Management guidelines of India explains about this. According to the reports, in temperate regions, a tonne of grains having 15 percent protein along with straw of maize, wheat, paddy and barely will absorb 25 kg of nitrogen.

In spring and autumn, the same will require 30 kg of Nitrogen. At the beginning stages of tillering, the nitrogen requirement will be 40-50 kg. We can approximately say that the requirement of nitrogen per tonne of grains varies in the range of 25-50 kg. The matching answer is 33 kg.
