GRANULAR DI-AMMONIUM PHOSPHATE

Granular Di-Ammonium Phosphate, or DAP, is a widely used high concentration nitrogen phosphorus compound fertilizer in agriculture. It features balanced nutrients, uniform granules and excellent stability. With favorable physical properties and high nutrient utilization rate, it contains high levels of available phosphorus and ammonium nitrogen. Nutrients release steadily and lastingly. It fits most grain crops and cash crops. It can serve as base fertilizer for long term soil nourishment and top dressing for plant growth. It is also a core base fertilizer for pesticide fertilizer blending, soil improvement and large scale planting. Suitable for field agriculture, protected agriculture and various large scale planting scenarios, it is a cost effective high quality general nitrogen phosphorus fertilizer with reliable application performance.

1. Product Introduction

This product is neat grey white granules with high hardness, low breakage rate and no dust. It has good looseness and low tendency of moisture absorption and caking, which facilitates storage, transportation and mechanical spreading. It has scientific nutrient ratio, high purity of nitrogen and phosphorus, few impurities and extremely low heavy metal content, meeting high standard agrochemical production requirements. Its aqueous solution is weakly alkaline and compatible with most soil types. It works well with most organic fertilizers, medium trace element fertilizers and neutral pesticides. Compared with ordinary phosphate fertilizers, it releases nutrients slowly and evenly with longer fertilizer efficiency period. It can continuously supply nutrients for the whole crop growth cycle, relieve nitrogen and phosphorus deficiency in soil and lay a solid foundation for crop growth.

2. Application Scenarios

1) Field crop planting: Suitable for wheat, corn, rice, cotton, soybean and other grain and cash crops. It is mainly applied as base fertilizer before sowing to improve soil fertility and cultivate strong seedlings.

2) Fruit, vegetable and forest crop planting: It can be used as base fertilizer and top dressing for fruit trees, melons and vegetables in early growth stage. It helps root development and shoot growth and improves flowering and fruit setting capacity.

3) Large scale mechanical operation: Uniform granules and good flowability make it compatible with large fertilizer spreaders and seed and fertilizer integrated machines, saving labor and time for large scale agricultural production.

4) Fertilizer blending processing: It can be used as core raw material for bulk blended fertilizer, formula fertilizer and pesticide fertilizer production to optimize nutrient structure and improve comprehensive application effect.

3. Application Benefits

It rapidly supplements nitrogen and phosphorus nutrients required by crops, strongly promotes root development and robust plant growth, and improves crop resistance to cold, drought, lodging and pests. Early application helps uniform and strong seedlings. Application in middle and late stages boosts flower bud differentiation and dry matter accumulation, greatly increasing crop yield and fruit quality. Proper long term application gradually improves soil structure and enhances soil water and fertilizer retention capacity, meeting the demand of green and high quality agricultural planting.

4. Notes

1) This product is weakly alkaline. Do not mix it directly with strongly acidic pesticides or fertilizers to avoid chemical reaction and nutrient loss.

2) Adjust application rate according to soil fertility, crop type and growth stage. Over application will cause phosphorus accumulation and nutrient imbalance in soil.

3) Store in cool, dry and ventilated area. Keep away from rain and wet ground with sealed package to prevent moisture absorption and caking.

4) Cover soil and water properly after mechanical fertilization to promote nutrient dissolution and absorption, improve fertilizer utilization rate and prevent nutrient volatilization loss.
