Nitrogen Responses and Nitrogen Management in Potato

Potato Research, 2009
Innumerable experiments have been carried out to establish the yield response of potato to the rate of nitrogen (N) supply. Given the continuing change in production level of potato and because of the need to maximise the nutrient use efficiency and to reduce losses of harmful nitrogenous compounds to the environment, such research is still necessary ...

Nitrogen Fertilization I: The Nitrogen Balance

2016
Nitrogen is the most important nutrient in agricultural production. The natural input of N is due to N fixation, especially by Rhizobium bacteria that infect the roots of legumes. Organic N becomes inorganic through mineralization, and then inorganic N is absorbed by plants.
