The yield response of winter cereals to sulfur and magnesium containing fertilizers with regard to mobile sulfur and exchangeable magnesium supply of podzoluvisol loamy soil
Abstract
The effect of S60 applied to soil as ammonium sulfate and the foliar spray of 4 % magnesium sulfate solution had been studied in the model field experiment with medium mobile S 7–10 ppm and four different levels of exchangeable Mg supply. The grain yield responses to the tested fertilizers were sufficient only on the low and medium content of Mg (45–120 ppm) in soil. Application of S60 to soil resulted with yield increase 0,76–0,65 t of wheat and 0,55–0,45 t of triticale. The same level of crop response was noted after foliar spray of magnesium sulfate: 0,75–0,58 t of wheat and 0,55–0,45 t of triticale. The assessment of mobile sulfur supply of arable soil in regions and district of Belarus has been done according to the data of 14 cycle of Soil Survey (2017–2020). In genera 2/3 of the area of arable soils in Belarus is characterized by a very low content of mobile sulfur with a difference by region from 15,1 % (Stolinsky district) to 99,9 % (Kruglyansky district).
