K+S Solumap 12:61:0 is a water-soluble, nitrogen-phosphorus fertilizer that is immediately available to plants. It is a highly concentrated source of phosphorus, with 61% P2O5, and also contains 12% nitrogen. Solumap is chloride and sodium-free, and has a slightly acidic pH value. This makes it ideal for use in fertigation systems, as it will not damage the irrigation equipment.

Solumap is especially important in the early growth stages of plants, as it helps to promote root development and nutrient uptake. It can also be used to improve the quality of fruit and vegetables, and to increase yields.
