Nitrate leaching and soil moisture prediction with the LEACHM model,op from February to April in two years and three locations. The model grossly overestimated soil water content, probably due to the bad fitting of the assumed water retentivity function to the experimental data at high water contents, and to the presence of a relatively shallow water table (1.0–1.5 作者: ALERT 時間: 2025-3-24 03:47 作者: Silent-Ischemia 時間: 2025-3-24 09:25

Modelling nitrogen dynamics in a plant-soil system with a simple model for advisory purposes,ling the water regime in soils with fluctuating water tables. A major problem seems to be the ‘disappearance’ of fertilizer N. Measurements by the fumigation-extraction method of microbial N during the growing season show that disappearance of fertilizer N can partly be explained by immobilization by the microbial biomass.作者: Intentional 時間: 2025-3-27 08:58
