Effect of calcium silicate on soil silicon content and upland rice grain yield
01/Sep/1999
In addition to improving chemical attributes of the soil, such as pH, exchangeable Ca and available Si, calcium silicate fertilization in soils with low soluble silicon (Si) can also affect rice yield due to a greater resistance to lodging and increased photosynthetic area. The objective of this study was to evaluate Si availability in soils from the Brazilian savannas (Cerrado). The experiment was carried out in a greenhouse using upland rice. The treatments consisted of 5 Si rates (0, 120, […]
Response of common bean to limestone application in lowland soils of southern Minas Gerais state, Brazil
01/Dec/1998
The experiment was conducted under greenhouse conditions at the Soil Science Department of the Federal University of Lavras, Lavras, from August 1995 to June 1996. The objectives were to evaluate the application of limestone on several chemical properties and on the nutrition and production of common bean cultivated in samples of four lowland soils and to compare the doses established as appropriate according to base saturation and Al and Ca + Mg methods. A 6×4 factorial scheme in a completely […]
