Nitrogen contribution of pea residue in a hummocky terrain

Topography influences the distribution of soil water and inorganic N which could affect the availability of N from legume residue to the subsequent crop. A study assessed the landscape-scale variability of the N contribution by pea (Pisum sativum L.) to the soil (N2 fixation in residue minus seed N...
