Effect of sulphur on soybean (Glycine max(L.) Merril) production

SUMMARY
Several cultures, such as coffee, cotton, corn, peanut, dry bean and soybean, have been observed to respond positively to sulphur applied under the form of gypsum (Ca SO4), in the State of São Paulo. On the other hand, it is known that sulphur is also added to the soil as a normal component of some fertilizers (e.g. superphosphate). The effect of such an "indirect" sulphur fertilization on the sulphur content of soybean leaves was studied.
Foliar analyses indicated that increasing dosis of single superphosphate resulted in increasing content of sulphur, in soybean leaves. There was no increase in phosphorus or calcium, the other components of this fertilizer, in the same leaves, possibly because the soil was well supplied for both elements. The results show that single superphosphate might be a source for sulphur fertilization.
