Humic Acids Has Strong Capability to Counter Droungt
Humic acid can help counter drought by improving soil water retention and increasing plant tolerance to drought stress. Humic acid is a natural substance that is found in soil, compost, and other organic matter.
When added to soil, humic acid can help to improve soil structure and water-holding capacity, which can increase the availability of water to plants and reduce water loss through runoff and evaporation. Humic acid can also help to stimulate beneficial microbial activity in the soil, which can further enhance soil health and water retention.
Most of Humic acids is extracted from Leonardite or peat through KOH ,NAOH or Ammonium Hydroside.Only the one extracted through KOH has the best effect when applied to plants together with Nitrogen or Phosphorus fertilize like Urea MAP DAP MKP.
Potassium humate is one of powerful soluble humic acids,is naturally organic matter directly supply to soil ,could create a proper environment for seeds germination.As humic acid could improve soil structure into crumb from compact condition,which is easy to hold water.
Humic acids has stronger CEC could chelate more nutrients like Zn,Cu,Fe, B and so on such microelements,also could largely stabilize nitrogen and slow release, unlock the phosphorus in the soil , directly supply potassium ,in the meanwhile optimize Ca Mg S .Accordingly ,could balance all the nutrients supply,the soil fertility is greatly increase.Thus the seed could grow a large and strong root system,in converse could absorb more nutrient and water.
Potassium ion could control close and open even regulate the stomata on the leaves,thus reduce leaf transpiration, reduce plant water consumption.
Through the above humic acids could work as naturally anti drought agent,such successful field test has been made in Henan province in China for wheat ,have good effect.
When applied to clay soils, humic acid can help break up compacted soils, allowing for enhanced water penetration and better root zone growth and development. When applied to sandy soils, humic acid adds essential organic material necessary for water retention thus improving root growth and enhancing the sandy soil’s ability to retain and not leach out vital plant nutrients.
