Soybean cultivation in the acid soils of low latitude Brazilian Savannahs (Cerrados) has become a reality since the 1970's. Soil fertility management and crop breeding have made major contributions to high standard performance of this crop. There are, however, factors that limit the prospect to sustainable production, such as levels of calcium in the soil, below the ploughed zone. This may prevent...
There are severe soil constraints for agriculture in many tropical regions of the world. Acidity and low levels of calcium are examples of them in the Brazilian Cerrados (Savannahs). They may prevent deep root growth of cultivated plants, exposing them to moisture stress during dry spells. This study aimed to develop a technique for screening soya bean varieties tolerant to low calcium based on root...
