Potassium humate Effect in Agriculture
Potassium humate is an organic colloidal substance with a function of water absorption and storage. Potassium humate has a large cation exchange capacity, strong adsorption buffering ability and chelating power, which can improve the nutrient utilization rate in the soil and buffer acid and alkali damage.
Potassium humate is an organic macromolecular colloid, which has a strong water absorption and storage function.The water absorption of clay particles is generally 50% ~ 60%, while the water absorption of potassium humate can reach 500% ~ 600%. Conducive to improving soil moisture conditions
It is the organic-inorganic complex that determines the soil fertility. Generally, the content of inorganic mineral colloids in the soil is as high as 95% or more, which has a certain effect on the basic fertilizer in the soil. It is not possible to change the colloids and humic acids by artificial measures. About 5% of the inorganic complex, potassium humate is used to increase the content of humic acids in the soil, so that potassium humate becomes an adhesive for the formation of soil aggregate structure. Improve soil organic-inorganic mixing. Increasing the large particle size water-stable aggregates of the soil improves the soil structure, so it is said that the use of potassium humate can effectively improve the physical structure of various soils.
Foliar spraying of potassium humate can reduce stomatal conductance and reduce water transpiration and loss. According to the test, spraying potassium humate on wheat has reduced the stomatal conductance of wheat leaves by 33.7% compared with the control. It reduces the stomata opening and closing of wheat, and also provides nutrients for wheat.
Potassium humate contains a variety of chemically and biologically active functional groups, which can stimulate the growth and development of crops. It can make the seeds germinate early, emerge early, flower early, and set fruit early. At the same time, it can increase root length, root volume and root vitality. To enhance the ability of crop roots to absorb nutrients and water.
Potassium humate can enhance the enzyme activities in soil and plants, regulate crop physiological and metabolic functions, and enhance the adaptability of crops to adverse environmental conditions.
Guidance for agriculture use
Potassium humate is strongly recommended used with Urea MAP DAP and MKP.Potassium humate could largely stabilize nitrogen and release lock up phosphorus in soil and increase soil water holding capacity,also will help to create optimal structure of soil for plants to absorb micro elements and other nutrients,block the heavy metals absorbed by plants thus stopped transfer to human.
