No. of bitstreams: 0 Previous issue date: 2014-01-01; One of the premises of the no-tillage system is the maintenance of straw on the soil surface. However, the particle size by different cutting implements used for straw formation can influence its rate of decomposition. Therefore, the objective of this study was to evaluate in a Red Latosol (Oxisol) unde...

No. of bitstreams: 0 Previous issue date: 2022-01-01; Soil pH values below 4.4 (acidity) limit nutrient availability and root exploration, whereas a pH range of 5.4–6.4 ensures the availability of most nutrients essential for crops. To ameliorate acidity in the surface and subsurface layers and improve soil chemical fertility, different application methodo...
