Takeaway
Pick DAP for acidic/calcareous soils and 20-20-0-13 for sulphur-deficient soils based on a soil test.
Summary
- DAP (Di-Ammonium Phosphate) contains 18% N and 46% P, suited to acidic and calcareous soils; apply 50 kg/acre in basal dose.
- 20-20-0-13 (Ammonium Phosphate Sulphate) has 20% N, 20% P and 13% sulphur - ideal for sulphur-deficient soils.
- DAP supplies higher phosphorus for stronger root system; 20-20-0-13 adds sulphur which improves protein content and chlorophyll.
- Choose based on soil test: acidic/calcareous soils get DAP; sulphur-deficient soils get 20-20-0-13; do not apply both together.
