TSP – DAP – MAP are Granular Fertilizers for Phosphorus Nutrition

TSP – DAP – MAP are granular phosphorus fertilizers for root crops like corn, wheat, and potatoes. TSP offers pure high-P for acidic soils and legumes, no N; DAP provides balanced N-P for early growth in neutral soils; MAP delivers highest P with low-pH ammonium N for alkaline soils and starters. All enhance roots and yields by 10-20%, with MAP safest for seeds.

Apply 200-400 lbs/acre pre-plant banded. TSP for P-only, DAP for N-P, MAP for high-P efficiency.
