Nitrogen balance and N recovery after 22 years of maize-wheat-cowpea cropping in a long-term experiment

  title={Nitrogen balance and N recovery after 22 years of maize-wheat-cowpea cropping in a long-term experiment},
  author={Dinesh Kumar Benbi and C. R. Biswas},
  journal={Nutrient Cycling in Agroecosystems},
The influence of N, P and K application through inorganic and organic fertilizers on N recovery in crop plants and its balance in the soil-plant (maize-wheat-cowpea fodder) was studied for the first 22 years of a long-term experiment at Punjab Agricultural University farm, Ludhiana, India. The results showed. that N removal and apparent N recovery by both maize and wheat was directly related to the balanced application of N, P and K fertilizers. Averaged over the years, application of N alone… CONTINUE READING
