Vegetable production primarily relies on the conventional tillage system (CTS), which leads to soil degradation through erosion and reduced health. The use of no-tillage vegetable systems (NTVS) aims mitigate these issues; however, information about impact this management health greenhouse gas (GHG) emissions remains limited. Thus, objective study was conduct an on-farm evaluation effects cover crop C N contents stocks, bulk density (SD), mean geometric diameter (MGD) aggregates,...
ABSTRACT Gypsum supplies Ca and Mg reduces Al saturation in deep soil layers. After gypsum application, a K source must be applied to minimize cation displacement. Cauliflower’s economic importance, its high S absorption, lack of knowledge about nutritional management drove the objective studying effects K2O on attributes cauliflower yield.
