Humic acids form chelates with nutrient elements of the soil, especially with iron, turning them into a form suitable for assimilation by plants, and thus optimizing the supply of nutrients in the soil. An increase in yields of up to 70% while reducing fertilizer and pesticide consumption by 30%, as well as accelerating growth and improving the health of grass, ornamental plants, agricultural crops and forests can be achieved by applying high-grade humic acids to the soil in a rusty manner. In addition, the soil's ability to moisture retention is significantly increased, which means a significant reduction in water costs.
The best economic results can be obtained on light and sandy soils with a low content of humus, as well as on reclaimed lands. The various positive effects of humic acids are especially visible on such soils. Such ruzatets are observed on almost all soils in dry and hot regions. Because of the high degree of mineralization of organic substances, the supply of such soils with humic acids, which have a stabilizing effect, is an indispensable method of maintaining and improving the fertility of lands.
Modern scientific research shows that the fertility of soils is largely determined by the level of humic acids in them. The high ability of the latter to cation exchange, the presence of oxygen, as well as water retention capacity above the average - all this demonstrates the value of humic acids as a means of improving soil fertility and accelerating plant growth. The most important property of humic acids is their ability to bind the ions of insoluble metals, their oxides and hydroxides and subsequently slow and continuous release as necessary for plant nutrition. Due to these properties, humic acids have three types of effects: physical, chemical and biological.
