Fertilizer.

What is nitrogen phosphorus potassium fertilizer?

Nitrogen fertilizer .

The roots of plants absorb nitrogen fertilizer. Nitrogen is the main component of proteins (including some enzymes and coenzymes), )nucleic acids, and phospholipids. They are important components of protosotics, nucleons and biofilms and play a key role in plant life activities. Nitrogen is a component of chlorophylis, so it is closely related to photosynthic use. Nitrogen levels directly affect cell division and growth. Therefore, the supply of nitrogen fertilizer is very necessary. Urea, ammonium nitrate and ammonium sulfate are widely used in agriculture.

Phosphate fertilizer .

Phosphorus promotes the development of roots, flowers, seeds and fruits. Phosphorus is involved in a variety of metabolic processes. Phosphorus is abundant in the divided tissue and has the most abundant production and life activities. Therefore, the use of phosphorus fertilizer has a good effect on the growth of branching, branching and rooting. Phosphorus promotes the conversion and transport of carbohydrates and the growth of seeds, roots and tubers. It can significantly increase crop yields.

- Potash . . .

Potash is used to promote stem growth, moisture flow and flowering results. Potassium (K) is concentrated in plants in the form of ions in the most prolific parts of a plant's life, such as growth points, formation layers, and leaves. Potassium promotes protein synthesis and the transport of sugar to ensure the absorption of blood from cells.

The benefits of fertilizer.

Fertilizers help plants grow
They contain one or more of the nutrients necessary for growth, such as nitrogen, phosphorus, potassium and various other substances. Once added to the soil, these nutrients can meet plant growth needs, provide them with nutrients they lack, or help them retain lost nutrients. Fertilizers provide specific nitrogen and phosphorus potassium formulations to treat undernourished soils and plants.

Fertilizer is more affordable than organic fertilizer.

Fertilizers are often much cheaper than organic fertilizers. On the one hand, from the production process of organic fertilizer, it is not difficult to find out why organic fertilizer is expensive: the need for higher costs to obtain raw materials for the production of organic fertilizer, as well as the government regulator organic certification of the more expensive costs.

Fertilizer, on the other hand, is cheap because it contains more nutrients per pound of weight, while the same nutrients require more organic fertilizer. It often takes a few pounds of organic fertilizer to provide the same soil nutrient levels as a pound of fertilizer. These two reasons directly affect the use of fertilizer and organic fertilizer. Some reports indicate that the U.S. fertilizer market is about $40 billion, of which organic fertilizer accounts for only about $60 million. The rest is the share of all kinds of man-made fertilizers.

More directly provide the nutrients needed for the crop.

The provision of immediate nutrition and low procurement costs have led to widespread use of fertilizers. Fertilizer has become the main choice for many farms, courtyards and gardens and a key component of the daily maintenance of lawns. But will fertilizers harm soil and plants? What should be paid attention to in the application of fertilizer? ?

Environmental problems arising from the application of fertilizers.

Contamination of groundwater resources.

Some compounds used in the manufacture of fertilizer synthesis can have a negative impact on the environment once they flow into groundwater resources. Nitrogen from farmland flowing into surface water accounts for 51% of humanactivity. Ammonia nitrogen and nitrous nitrogen are the main pollutants in rivers and lakes, and are the main causes of water pertrophication and groundwater pollution.

Destruction of soil structure
With the long-term large-scale use of fertilizer, soil acidification, skin and other environmental problems. Due to the large amount of nitrogen fertilizer rather than organic fertilizer, resulting in some tropical farmland soil skin serious, and ultimately lead to the loss of agricultural value of soil. The effects of fertilizer on the soil are irreversible.

Long-term use of fertilizers alters the pH of the soil, destroys beneficial microbial ecosystems, increases pests and even leads to the release of greenhouse gases.

Many types of fertilizers are highly acidic, which in turn tends to increase the acidity of the soil, thereby reducing beneficial organisms and hindering plant growth. By destroying this natural ecosystem, long-term use of synthetic fertilizers can eventually lead to chemical imbalances in receptor plants.

Reuse can lead to the accumulation of toxic chemicals such as arsenic, cadmium and uranium in the soil. These toxic chemicals will eventually enter your fruits and vegetables.

There is a certain understanding of fertilizer use and can be avoided in the purchase of fertilizer.

Unnecessary waste can also increase crop yields.

Use fertilizer correctly.

Fertilizer is a double-edged sword. It is productive and destructive, depending on the number of applications . . . Fertilizers are selected according to the characteristics of the soil.

Before you buy fertilizer, know the soil pH.  If the soil is acidic, the amount of organic fertilizer can be increased, the control of nitrogen can be maintained, and the amount of phosphorus fertilizer can be maintained.

The combination of fertilizer and organic fertilizer.

The use of organic fertilizers and fertilizers is essential for agricultural production. Research shows that it is beneficial to the transformation of soil organic matter. With the use of organic fertilizer and fertilizer, the renewal of soil organic matter and the improvement of soil cation exchange ability can help to improve soil enzyme activity and increase the absorption of nutrients in crops. It helps to improve crop quality, increase the content of protein, amino acids and other nutrients, and reduce the content of nitrates and nitrites in vegetables and fruits. Choose the right method of fertilization.

In terms of fertilization techniques and environmental conditions, nitrate content of vegetables and crops is closely related to soil nitrogen types. The higher the nitrogen concentration in the soil, the higher the nitrate content in the vegetables, especially in the later stages. Therefore, the application of fertilizer should be early, not too much. Nitrogen fertilizer should not be sprinkled, otherwise it will cause volatility or loss. Because the mobility of phosphorus fertilizer is low, it should be buried deep and used.

Fertilizer also has a great impact on the environment.

Fertilizers have the risk of groundwater contamination and the soil problems it causes. So we must understand what is happening to the land beneath our feet so that we can make the right choice more consciously.

The principle of fertilization.

Reduce the amount of fertilizer used, with the application of organic fertilizer. Nutritional diagnosis is carried out according to local soil conditions and fertilization is carried out according to actual needs. To do according to the time, according to local conditions to protect the environment.
