•Improved structure of soil: It prevents high water and nutrient losses in light, sandy soils, simultaneously converting them into fruitful soils by way of decomposition. In heavy and compact soils, aeration of soil and water retention is improved; cultivation measures are facilitated. •Prevents soil cracking, surface water runoff and soil erosion by increasing the ability of colloids to combine. •Helps the soil loosen and crumble, and thus increases aeration of soil as well as soil workability. • Increases water holding capacity of soil and thus helps resist drought. •Darkens the color of the soil and thus helps absorption of the sun’s energy. Humic acids chemically change the fixation properties of the soil, with benefits such as: •Neutralizes both acid and alkaline soils; regulates the pH-value of soils. •Improves and optimizes the uptake of nutrients and water by plants. •Acts as natural chelator for metal ions under alkaline conditions and promote their uptake by the roots. •Becomes rich in both organic and mineral substances essential to plant growth. •Retains water soluble inorganic fertilizers in the root zones and reduces leaching. •Promotes the conversion of nutrient elements (N, P, K + Fe, Zn and other trace elements) into forms available to plants. •Enhances the uptake of nitrogen by plants. •Reduces the reaction of phosphorus with Ca, Fe, Mg and Al and liberates it into a form that is available and beneficial to plants. The productivity of particular mineral fertilizers is increased considerably. •Liberates carbon dioxide from soil calcium carbonate and enables its use in photosynthesis. •Helps to eliminate chlorosis due to iron deficiency in plants. •Reduces the availability of toxic substances in soils. Humic acids biologically stimulate the plant and the activities of micro-organisms such as: •Stimulates plant enzymes and increase their production. •Stimulates growth and proliferation of desirable micro-organisms in soil. •Enhances
