Advantages of amino acid fertilizers Amino acid fertilizers contain a variety of nutrients, and it is well known that they have complete nutrients and the highest activity. Amino acid fertilizers have been developed and mass-produced in the United States, Australia, Canada, Japan, etc. and Taiwan, and the products have already entered the international market. The development and application of amino acid fertilizers in my country will also develop rapidly in recent years.
The functions and advantages of amino acid fertilizer have the following six points:
- Amino Acids can promote photosynthesis of plants.
Glycine in the amino acid can increase the content of plant chlorophyll, promote the absorption and utilization of Carbon Dioxide by crops, increase power for photosynthesis, and make photosynthesis more vigorous. - A variety of amino acids have good nutrition effect.
The effect of amino acid mixed fertilizer is higher than that of single amino acid with equal nitrogen content, and it is also higher than that of inorganic nitrogen fertilizer with equal nitrogen content. Many amino acids improve the utilization of nutrients with its superimposed effect. - Fast fertilizer effect.
Amino acids in amino acid fertilizers can be directly absorbed by various organs of plants, passively absorbed or osmotically absorbed under photosynthesis, and obvious effects can be observed in a short period of time after use. At the same time, it can promote the early maturity of crops and shorten the growth cycle. - Improve crop quality.
Abundant kinds of amino acids can improve the quality of crops. For example, the protein content of grain is increased by 3%, the cotton flower has good velvet quality and the fiber is long; the vegetable has good palatability, pure and delicious crude fiber reduces the flower blooming period, the flower color is bright, the fruit is rich, the fruit color is good, the sugar increases, the edible part is more resistant, has good storability, and remarkable conversion efficiency. - Clean and pollution-free, improve the ecological environment.
The amino acid fertilizer applied to the ground has no residues, which can improve the physical and chemical properties of the soil, improve the water retention, fertility, and air permeability, and play the role of curing, maturing, and improving the soil. - Enhanced metabolic function and improved resistance to stress.
After being absorbed by crops, amino acids can strengthen their physiological and biochemical functions. Crop stalks are thick, leaves are thickened, leaf area is enlarged, dry matter formation and accumulation are accelerated, and crops can mature earlier due to their increased vitality, resistance to cold and drought, resistance to dry and hot wind, resistance to diseases and insect pests, and lodging resistance, thereby achieving stable and high yield. - Developed root system, strong absorption.
Amino acids have a special promotion effect on the root development of crops. Many agricultural personnel call amino acids as “root fertilizers.” Their effects on the root system are mainly manifested in stimulating the division and growth of root meristem cells, so that the seedlings can take root quickly. The secondary roots increase, the root mass increases, and the root system elongates, which ultimately leads to a greatly enhanced ability of crops to absorb water and nutrients. - Effects on the growth of some above-ground vegetative bodies.
Based on sufficient nutrient supply, the stimulating effect of amino acids can make the above-ground part of the plant grow vigorously, which is manifested in plant height, stem thickness, number of leaves, dry matter accumulation, and so on. - Impact on output and composition factors.
Amino acids have different yield and composition factors for different crops. They can increase the yield of food crops such as more ears, more grains, and 1,000-grain weight. The early stage has a good effect on tillering and reducing the empty rate.
Effects of amino acids on crop physiological metabolism and enzyme activities:
After the amino acid enters the plant body, it stimulates the plant, which is mainly manifested in the increase of the respiratory intensity, the increase of photosynthesis, and the enhancement of the activity of various enzymes, so that the fruit is ripened in advance, and high yield is achieved.
According to the experiment of Southwest Agricultural University, the sugar content of watermelon increased by 13-31.3% and the vitamin C content increased by 3-42.6% after amino acid was applied.
In addition, amino acids have a synergistic effect on chemical fertilizers:
- Synergistic effect on nitrogen fertilizer.
Urea, ammonium bicarbonate, and other small nitrogen fertilizers have strong volatility and low utilization rate. Farmers generally believe that they are “violent, fierce, and short.” When mixed with amino acids, they can increase the absorption and utilization rate by 20-40% (carbon amine release takes more than 20 days for the nitrogen to be absorbed by crops, and it can reach more than 60 days after mixing with amino acids).
In addition, the influence of amino acids on the potential nitrogen in the soil is multifaceted. The stimulating effect of amino acids increases the prevalence of soil microorganisms, leading to faster organic nitrogen mineralization. Amino acids have a higher base exchange capacity and can reduce nitrogen volatilization loss, also increasing the soil available nitrogen content. - Synergistic effect on phosphate fertilizer.
Research on the effects of amino acids on phosphate fertilizers has been carried out abroad for many years, and China has also conducted research in this area. The results show that without adding amino acids, phosphorus moves vertically in the soil for 3 to 4 cm. After adding amino acids, it can increase to 6 to 8 cm. Nearly doubled, it is helpful for the absorption of crop roots. Amino acid has an obvious effect on the decomposition of phosphate rock. It also protects the available phosphorus and reduces the soil’s fixation of available phosphorus. It promotes the absorption of phosphorus by crop roots and improves the efficiency of phosphate fertilizer. The utilization rate of absorption has extremely high value. - Synergistic effect on potash fertilizer.
The synergistic effect of amino acids on potassium fertilizers is mainly manifested in the acidic functional groups of amino acids can absorb and store potassium ions, prevent water loss in sandy soil and strong leaching soil, and prevent clay soil from fixing potassium. Potassium silicate, potassium feldspar, and other minerals have a corrosive effect, which can slowly decompose and increase the release, thereby increasing the content of soil available potassium.
In addition, amino acids also contain a variety of nutrient elements, which have long-lasting and quick-acting fertilizer effects on the growth of crops. Therefore, amino acids can be used as foliar fertilizers for foliar spraying, which can supplement nutrients and improve photosynthesis simultaneously, laying a solid foundation for the high yield of crops.
