The Most Concentrated Phosphate-Based Fertilizer
Diammonium Phosphate (DAP) NP 18:46 is the most concentrated phosphate fertilizer available, delivering optimal phosphorus nutrition throughout the growth cycle of your crops. It also provides a valuable starter dose of nitrogen and a small amount of sulfur to promote balanced nutrition.
DAP is highly versatile and can be applied in autumn for tilling, in spring during sowing, or for pre-sowing cultivation. When it dissolves in soil, it temporarily increases the alkalinity of the soil solution around the granules, enhancing phosphorus uptake, especially in acid soils.
The sulfur content in DAP further supports the efficient uptake of nitrogen and phosphorus, helping plants to thrive and maximize their growth potential. Ideal for all types of agricultural crops, DAP ensures your crops receive the essential nutrients they need for healthy, robust development.
Optimized for winter cereals
DAP is an excellent fertilizer for winter cereals like wheat, barley, and rye, promoting early root growth and improving resistance to cold stress.
Improved yield and crop performance
DAP enhances overall crop yield by providing essential nutrients that support plant growth, particularly in phosphorus-deficient soils.
Root system development
Ensures a strong and healthy root system, which is vital for water and nutrient absorption, especially during early growth stages.
Supports plant quality
Helps improve the quality of plant products by supplying phosphorus that is essential for energy transfer and flower and fruit development.
Sulfur for nutrient absorption
The sulfur content in DAP enhances the plant’s ability to absorb nitrogen and phosphorus, improving the efficiency of the fertilizer.
