Soil organic carbon stock is improved by cover crops in a tropical sandy soil
Cordeiro, Carlos Felipe dos Santos [UNESP]; Rodrigues, Daniel Rodela; Silva, Gustavo Ferreira da [UNESP]; Echer, Fábio RafaelMade available in DSpace on 2022-04-28T19:51:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Soil organic matter plays an important role in soil quality. In sandy soils of tropical regions, high biological activity in the soil accelerates mineralization and limits increases in organic matter content. The objective of this study was to evaluate the total organic C stock and the chemical and phys...

Rigon, João Paulo Gonsiorkiewicz [UNESP]; Calonego, Juliano Carlos [UNESP]; Pivetta, Laércio Augusto; Castoldi, GustavoMade available in DSpace on 2022-05-01T09:30:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Crop rotations under no-till (NT) have been a strategy to increase soil organic carbon (SOC) and mitigate greenhouse gas (GHG) emissions, enhancing the cropping system efficiency. However, there is still controversy on the role of grasses and legumes, and species diversity and their impacts. This study ...
Liming optimizes nitrogen fertilization in a maize-upland rice rotation under n...
Crusciol, Carlos Alexandre Costa [UNESP]; Momesso, Letusa [UNESP]; de Campos, Murilo [UNESP]; Bossolani, João William [UNESP]Made available in DSpace on 2022-05-01T09:31:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-10-01; Liming and N fertilization are common practices for optimizing crop yields in tropical agriculture, but the adequate N rate to ensure crop development, enhance yields and N use efficiency, and improve soil chemical properties has not been established for grass rotation. We assessed the optimal N fertili...
