The Brazilian savannas (“Cerrado”) occupy 204 million ha with low-fertility acid Oxisols the dominant soils. Sulphur (S) deficiency is widespread in the region. Incorporation of sulphate sources (largely single superphosphate and ammonium sulphate) into fertilizer formulations leads to lower NPK concentrations and higher transport costs compared to high-analysis S-free NPK formulations. Elemental sulphur, with nearly 100% S, offers a cost-effective alternative to incorporate S into fertilizer formulations. A field experiment
was carried out on a clayey Cerrado Oxisol to evaluate the agronomic efficiency of experimental “Sulphur Enhanced Fertilizers (SEF)” containing varying proportions of microfine elemental S and sulphate incorporated into granules of mono-ammonium phosphate and triple superphosphate. Powdered calcium sulphate (phosphogypsum) was used as the reference S source. Fertilizers were band applied and the fresh and residual effects evaluated in a soybean-wheat rotation for one year (two crops). Grain yields,
aboveground S content, S concentration in diagnostic leaves and SPAD values were measured for both crops. There was no significant yield response to S or difference in above ground S content in the soybean crop. There was a significant response to freshly applied gypsum and SEF 774 in the wheat crop, with a higher S content in the gypsum treatment. The residual effectiveness of gypsum, and the two SEF treatments was equal in both yield and S content in the wheat crop.
