Effects of superficial liming and silicate application on soil fertility and crop yield under rotation
Soil acidity and low natural fertility are the main problems for grain production in Brazilian 'cerrado'. Although lime has been the most applied source for soil correction, silicate may be an alternative material due to ...
Upland rice growth and mineral nutrition as affected by cultivars and sulfur availability
A better understanding of the differential growth of upland rice (Oryza sativa L.) cultivars with increasing soil S availability could help improve rice yield under upland conditions. The objective of this study was to ...
Are high-lysine cereal crops still a challenge?

Improving soil fertility and crop yield in a tropical region with palisadegrass cover crops
In tropical regions with dry winters, low plant biomass accumulation during the period between spring–summer crop cultivations can negatively impact soil resources and make the no-till (NT) system unsustainable. Incorporating ...
