how humic acid works in plants
How potassium humic acid works in plants? First we need to now about what is humic acid?
khumic humic acid fertilizer grade is made of natural young leonardite, it is ideally suited for addition with granular fertilizers,such as Urea. Potassium humate fertilizer with prominent effect to release the locked phosphate by some ion such as Fe3+,Al3+, humate potassium also can slow-release nitrogen fertilizer to promote the function of NPK fertilizers.
Potassium humic acid would be classified as Plant Growth Regulator，which are products that stimulate the nutrition processes on plants.
When this product is applied to clay soils, it helps to break the compacted soils and it allows to increase the water penetration and to improve the growth and development area of roots.
When it is applied to sandy soils, it adds the essential organic matter, which is needed for water retention. Therefore, roots can grow and the clay soils can keep and avoid the washing of vital nutrients for plants.
How humic acid works in plants?
The plant growth is also favoured, due to the improvement of the plant hability for absorbing nutrient.
The activity of the beneficial soil microorganisms is crucial for the soil sustainability and for the plant growth. Humic acids stimulate the microbial activity, because they are a carbon source for their alimentation, favouring then their growth and activity. Soil microorganisms are responsible of the nutrient solubilization, like phosphor, making them available for the plant.
a) efficience in the use of nutrients
b) tolerance to abiotic stress
c) quality characteristics
d) availability of nutrients that are inmobilized in the soil or the rizosphere
What is the manufacture process of potassium humate?
For the manufacture of humic acid, we start with mineral leonardite. After the proper treatment of this raw material, we obtain humic extracts of more quality and agronomically profitable.
The benefits of potassium humic acid use are:
1.Addition of organic matter to deficient soils and increase of soil fertility.
2.Increase of vitality and root development.
3.Increase of the cation exchange capacity and improvement of nutrient absorption.
4.Increase of chlorophyll synthesis.
5.Improvement of seed germination.
6.Stimulation of beneficial microbial activity.
7.Improves the soil structure and the water retention capacity.
8.It naturally chelates the microelements of alkaline soils and increases its availability for plants.
How potassium humate improve the natural fertility of the soil?
1:Physical:
Increases the soil airing.
Improves the soil work.
Helps to resist drought.
Improves germination.
Makes the soil more friable or breakable.
Reduces soil erosion.
2:Chemical:
It chelates nutrients to improve its absorption by plants.
It has a high cation exchange capacity.
Increases the buffering capacity of soils.
Increases the total nitrogen percentage on soils.
3:Biological:
Accelerates the celular división and promotes growth.
Increases the seeds germination and their viability.
Increases the formation and respiration of roots.
Stimulates growth and the proliferation of soil microorganisms.
Helps the photosynthesis.
The use of the product on a regular basis reduces the fertilization needs, because both, soil and plant, are going to do a better use of nutrients. In some cases, fertilization can be completely eliminated if the is enough organic matter, so the soils can be self-sufficient through the microbial processes and the hummus production.
