The elements needed for plant growth, except for carbon, hydrogen, and oxygen, can be obtained from the air and water, and the rest need to be taken from the soil. If there is a deficiency, it needs to be added, that is, fertilization. In order to effectively fertilize plants, the nutrients of fertilizers, as well as the location, amount and time of fertilization, are important factors that must be considered.
Plant nutrient elements
Plants need sunlight, air, water, and the changes in temperature and humidity around them, but what depends on them to grow stronger?
Fertilization can make the soil fertile and beneficial to plant growth.
The elements needed for plant growth, except for carbon, hydrogen, and oxygen, can be obtained from the air and water, and the rest need to be taken from the soil. If there is a deficiency, it needs to be added, that is, fertilization. The fertilizer components of plants can be divided into a large number of elements (nitrogen, phosphorus, potassium), minor elements (sulfur, calcium, magnesium) and trace elements (chlorine, iron, boron, manganese, zinc, copper, cobalt, nickel). ,molybdenum).
How plants absorb fertilizer
Fertile soil should have good physical, chemical, microbiological, rich and balanced nutrients, and no factors that are unfavorable to crop growth, and provide a suitable environment for plants to allow well-extended pores and environmental cushioning. To make it play the absorption function. However, the fertile farmland soil is not everywhere, sometimes due to different soil textures and rainfall conditions in various regions, resulting in poor soil ventilation, water retention and fertilizer retention. In addition, long-term cultivation of crop land will also be absorbed by the growth of plants, resulting in decreased organic matter content, lack of nutrients, and increasingly poor soil. Through the application of fertilizer, the soil can be restored to the ground and provide the elements needed for plant growth.
Fertilizer is a nutrient element necessary for the growth and development of one or more plants, natural or synthetic. About 30-50% of the increase in crop yield is due to the application of natural or inorganic chemical synthetic commercial fertilizer. 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. The nutrients absorbed by plants through roots or leaves are almost all ionic. Whether it is chemical fertilizer or organic fertilizer after microbial mineralization, it must be dissolved in soil solution, and then diffused, mass flow, root interception, etc. Plant absorption and utilization. Therefore, the fertilizer will dissociate into an ionic state in the water, exchange the charge with the roots, and let the nutrients enter the surface of the root.
The more fertilizer, the better?
Through the appearance diagnosis of plants' leaves and accurate soil diagnosis, it is confirmed that what kind of fertilizer is applied and how much is used, so that it will not be fertilized by excessive amount of money, resulting in no more money and no crops, or loss of crops due to fat injuries.
The elements necessary for plant growth are distinguished by a large amount, but they are all important. In order to maintain normal growth, the amount of these elements must be balanced in a certain proportion. As long as the proportion of one element is low, the growth of the whole plant is limited by it. It is necessary to make up this element in order to continue growing. This is the plant. The least nutrient law of growth. Therefore, it is necessary to apply fertilizer to the most deficient elements in the soil to get results.
