Symptoms of soybean deficiency: Initially, the new leaves were pale yellow-green, but the old leaves were normal; when the plants were severe, the whole plants turned yellow, the leaves were small, and the internodes were short; the roots were elongated and the nodule developed. Soybean sulphur content According to Bansal (1983), the critical value of sulphur content in soybeans was 0.15% at 36 days of growth and 0.19% at 60 days of growth. The critical value of N:S in vivo is 16.5:1. The critical value of soil available sulphur in soybean field: calcium chloride (0.15%) extraction method is 14 mg S/kg; monocalcium phosphate extraction method is 14 mg S/kg; Morgan extraction method is 8 mg S/kg; Ammonium acetate (0.5 mol/L) + acetic acid (0.25 mol/L) extraction method was 8 mg S/kg. Correcting sulfur deficiency in soybeans The application of sulphur fertilizer not only increases the yield but also increases the fat and protein content of the seeds. The general sulphur fertilizer dosage is 20-40 kg sulfur/ha. According to China's six soybean sulfur fertilizer test statistics, the increase rate is 6.4% -33%, an average increase of 15%. The application of sulphur and urea in the Pacific High Islands increased 21% to 45% of the production of urea alone.
