1. 11. Nutrient economy in annual and perennial crops : comparisons between and within crop species in a sustainability context

   Författare :Fereshteh Pourazari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Nitrogen use efficiency (NUE) of agricultural crops is related to crop nitrogen (N) uptake and thereby the amount of N that is removed from agro-ecosystems through crop harvest. As the N removal through harvest is linked to the fertilization requirements and the risk of N leaching, the crop NUE is an important aspect of sustainability in agriculture. LÄS MER
