Potassium humate application in fruits trees
As a natural soil amendment, humic acid has been widely used in banana cultivation. Humic acid has improved soil structure, promotes the formation of soil aggregate structure, improves soil permeability and water retention capacity, and also regulates soil pH.
However, humic acid is mostly applied in the form of water-soluble fertilizer and organic-inorganic fertilizer. At present, there are still few products that can be combined with compound fertilizer nutrients for large-scale application, soil improvement and nutrient supply.
The main producing areas of bananas are concentrated in several provinces and regions in the south, while the south is mostly red soil. The soil is sticky and the gas permeability is not good. This is a thorny problem commonly encountered in banana planting.
Under the vegetation conditions of the evergreen and broad-leaved forest in the mid-subtropical hot and humid climate, red soils undergo desiliconization and aluminum enrichment processes and bioaccumulation, and develop into red, acidic, iron-aluminum surplus, and high-saturated iron-aluminum soil.
The banana root group is tender and has strict selectivity to the soil. It is better to have a deep soil layer and a high organic matter content. Soil conditions not only affect the growth of bananas, but also have a major impact on the occurrence of banana diseases.
A variety of banana pests and diseases are soil-borne diseases, of which banana wilt is known as banana cancer. Banana wilt enters the banana through the banana roots in the soil, and then the disease occurs, once the disease loss is irreparable.
Therefore, in the actual planting, it is necessary to maintain the integrity of the banana root system and ensure that the root system does not have wounds, which can effectively reduce the incidence of banana wilt. At the same time, robust plants and roots have better resistance, especially when roots are damaged.
Potassium humate is a natural biostimulant with no toxic side effects. It has unique effects in improving banana growth and stress resistance. In combination with certain farming measures that do not damage the roots, the application of potassium humate to bananas can reduce the occurrence of blight to a certain extent.
In terms of biostimulation, potassium humate has good water solubility and the effect is more prominent. It can also add potassium to bananas.
Bananas are more than potassium, and the demand for potassium exceeds that of many crops.
The ratios of nutrient uptake by nitrogen, phosphorus and potassium in the growth period of different banana varieties were about the same, with an average of 1:0.19:3.72. Potassium humate as a potassium source has good cost performance and effect on bananas, and is the first choice for banana growers.
