<p>An organic-mineral soil improver comprises >=2 of (a) assimilable carbon cpds. (b) amino acids and biogenic amines, and (c) mineral nutrients and trace elements. The prod. is a NPK (nitrogen, phosphorus, potassium) fertiliser which improves the soil and promotes plant growth. The fertiliser is free from components harmful to plants and is a high-activity biological substrate for maintaining and intensifying the microbial capability of the soil of nutrient humus formation. The aeration and water holding capacity of the soil is increased.</p> |
