The side-dressing fertilization of annual crops should consider S, beside N and K, in order to add protein value to the crop production. This work was carried out in the crop year 2004/2005, in the Farm Floresta do Lobo – Pinusplan, located at the km 93 of BR 050 highway, in the county of Uberlândia (MG). The experiment was installed in ácric Red Latossol typical Cerrado phase clayed (720 g kg-1), with the following objectives: to measure the losses by […]

A field experiment was conducted in the state of Paraná, Brazil, to evaluate the effect of liming on soil acidity, soil nutrient availability and yields of maize and soybeans on a Red Latosol (Oxysol), which had been cultivated for three, six and nine years under no-tillage (NT). Lime was broadcasted to the soil surface in four rates- 0, 33.3, 66.7 and 100% of the amount calculated to increase the soil base saturation (V%) to 70%; an additional treatment consisted of […]

A greenhouse experiment was carried out during the period October, 1991 to December, 1992, to evaluate the mass flow and diffusion contributions on sulphur transport to corn roots in soil surface samples (0-20 cm) of three acid soils collected in Viçosa, Paracatu and Lassance, Minas Gerais State, Brazil. Originally, the soil samples presented 5.0, 1.2 and 1.4 mg dm-3 of available S, respectively, obtained by extraction with a Ca(H2PO4)2 solution containing 500 mg L-1 of P in HOAc 2 mol […]
