How Plants Absorb Fertilizer

- Apr 12, 2020-

The fertile soil should have good physical, chemical, microbiological, rich and balanced nutrients, and there are no factors that are not conducive to the growth of crops, and should provide a suitable environment for plants to allow pores to fully expand and environmental buffer. In order to make it play an absorption function. However, fertile farmland soil does not exist everywhere, sometimes due to different soil texture and rainfall conditions in various regions, resulting in poor soil ventilation, water retention and fertilizer retention. In addition, long-term arable land will also be absorbed by the growth of plants, resulting in reduced organic matter content, nutrient deficiencies and increasingly poor soil. By fertilizing, the soil can be restored to the ground and provide the elements needed for plant growth.

Fertilizer is one or more nutrients necessary for the growth and development of natural or synthetic plants. The increase in crop yields by about 30-50% is due to the use of natural or inorganic chemically synthesized commercial fertilizers. There are many types and brands of fertilizers on the market, which can be divided into inorganic fertilizers and organic fertilizers, which are usually used directly in the soil or sprayed on the leaves. Almost all nutrients absorbed by plants through roots or leaves are ionic. After microbial mineralization, whether it is a chemical fertilizer or an organic fertilizer, it must be dissolved in the soil solution, and then absorbed and utilized by plants through three ways: Root interception, Mass flow and Diffusion. Therefore, the fertilizer will decompose into ionic state in the water, exchange charge with the root, and allow nutrients to enter the surface of the root.
