Cotton is responsive to boron fertilization, however, results on the mobility of this nutrient in the plant are few and controversial. This study had the objective of evaluating boron translocation and accumulation in cotton cultivars. Four cotton cultivars (FM 993, FM 910, FMT 701, and FMT 523) were grown for six weeks in 8 L pots with washed sand and nutrient solution at two boron concentrations (0 and 4.5 ∝mol L-1). After six weeks, plants were sampled for four more […]

Lime mobility and soil acidity correction can be influenced by liming management and the quantity and quality of soil organic matter. Acidity neutralization in function of the lime incoporation and surface liming was evaluated in a red Latosol (Oxisol) under different antecedent vegetation covers (eucalyptus, forest, pasture and pine). The study was carried out from November 2002 to January 2003 at the Soil Science Department of the Lavras Federal University. After 30 days of incubation of soils with lime, the […]
