A farmer after testing the soil reports to you that his land is poor in nitrogen content. What suggestive measures you provide to him?

Answer»
  • He can grow leguminous plants along with other crops by mixed cropping or crop rotation. 
  • The symbiotic bacteria Rhizobium forms root nodules in legume plants and fixes atmospheric nitrogen as nitrate salts in the soil which increases fertility of the soil. 
  • Biofertilizers Eg : Nostoc, Anabaena can also be used to increase soil fertility.
