What is the benefits of humic acids
Humic acids are an excellent natural and organic way to provide plants and soil with a concentrated dose of essential nutrients, vitamins and trace elements. They are complex molecules that exist naturally in soils, peats, oceans and fresh waters. The best source of humic acids are the sedimentation layers of soft brown coal, which are referred to as
Physical benefits of humic acids:
Humic acids physically modify the structure of the soil. .
Improve the structure of soil: Prevent high water and nutrient losses in light, sandy soils. Simultaneously convert them into fruitful soils by way of decomposition. In heavy and compact soils, aeration of soil and water retention are improved; cultivation measures are facilitated.
Prevent soil cracking, surface water runoff and soil erosion by increasing the ability ofcolloids to combine.
Help the soil to loosen and crumble and thus increase aeration of soil as well as soil workability.
Increase water holding capacity of soil and thus help resist drought.
Darken the color of the soil and thus help absorption of the sun energy.
Chemical benefits of humic acids:
Humic acids chemically change the fixation properties of the soil.
Neutralize both acid and alkaline soils; regulate the pH-valueof soils.
Improve and optimize the uptake of nutrients and water by plants.
Increase buffering properties of soil.
Act as natural chelator for metal ions under alkaline conditions and promote their uptake by the roots.
Rich in both organic and mineral substances essential to plant growth.
Retain water soluble inorganic fertilizers in the root zones and reduce their leaching.
Possess extremely high cation-exchange capacities.
Promote the conversion of nutrient elements (N, P, K + Fe, Zn and other trace elements) into forms available to plants.
Enhance the uptake of nitrogen by plants.
Reduce the reaction of phosphorus with Ca, Fe, Mg and Al and liberate it into a form that is available and beneficial to plants. The productivity of particularly mineral fertilizers is increased considerably.
Liberate carbon dioxide from soil calcium carbonate and enable its use in photosynthesis.
Help to eliminate chlorosis due to iron deficiency in plants.
Reduce the availability of toxic substances in soils.
Biological benefits of humic acids:
Humic acids biologically stimulate the plant and the activities of micro-organisms.
Stimulate plant enzymes and increase their production.
Act as an organic catalyst in many biological processes.
Stimulate growth and proliferation of desirable micro-organisms in soil.
Enhance plants natural resistance against disease and pest.
Stimulate root growth, especially vertically and enable better uptake of nutrients.
Increase root respiration and root formation.
Promote the development of chlorophyll , sugars and amino acids in plants and aid in photosynthesis.
Increase vitamin and mineral content of plants.
Thicken the cell walls in fruits and prolong the storing and shelf time.
Increase germination and viability of seeds.
Stimulate plant growth (higher biomass production) by accelerating cell division, increasing the rate of development in root systems and increasing the yield of dry matter.
Increase the quality of yields; improve their physical appearance and nutritional value.
