Depending on the harvesting and sowing dates of main crops, it can last from several days in the case of late harvest followed by sowing of a winter crop, to several months (up to 9 months) in the case of a spring crop. During this period, soil that is left “bare” (without plants), espe作者: 收集 時(shí)間: 2025-3-22 13:55

Main Lessons Drawn from the Simulation Study,on of the soil and climate context in a broad range of French conditions. By doing so, it will be possible to optimize the associated management technique and identify situations in which their use may have negative consequences on the next crop and, potentially, on groundwater recharge.作者: concubine 時(shí)間: 2025-3-24 03:02

This broad range of efficacy needs to be analysed on the basis of factors determining water drainage and nitrate leaching, as well as the other multiple functions of cover crops.作者: abnegate 時(shí)間: 2025-3-24 18:09

The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the dra作者: artless 時(shí)間: 2025-3-24 22:36 作者: SEMI 時(shí)間: 2025-3-25 02:30 作者: Prognosis 時(shí)間: 2025-3-25 07:07 作者: Bricklayer 時(shí)間: 2025-3-25 09:03
