Reasons for watering when fertilizing farmland

In the process of crop planting, fertilization and watering are very critical. Due to different crops, the methods of fertilization and watering are also different. Many crops are watered at the same time as fertilizer is applied, which helps improve fertilizer efficiency and crop yields. Below, the editor will introduce the reasons for watering when fertilizing farmland. Let’s take a look.

1. Reasons for watering when fertilizing farmland

1. Reduce the concentration of soil solution: Timely watering after fertilization can reduce the concentration of soil solution, making it close to or lower than the concentration of plant cell fluid, thereby preventing plant cells from losing water.

2. Promote the dissolution of inorganic salts: Inorganic salts must be dissolved in water before they can be absorbed by plant roots. Watering helps dissolve and diffuse inorganic salts in the soil and improves the utilization rate of fertilizers.

3. Improve the soil environment: Watering can also promote the activity of soil microorganisms, improve soil structure, and benefit the growth and development of plant roots.

2. Methods of fertilizing and watering farmland

1. Fertilizer flushing method

Sprinkle the fertilizer into the irrigation ditch. After the fertilizer dissolves in the lower ditch, it flows into the field with the water and seeps into the soil around the crop roots. The fertilizer flushing method saves time and labor, has low labor intensity and is easy to operate. The fertilizer flushing method may cause the loss and waste of fertilizers. Some fertilizers may flow into places where fertilizers are not needed, or leak and be lost in ditches.

2. Drip irrigation fertilization method

In the cultivation method of mulching and drip irrigation, fertilizer is dissolved in water and applied through the drip irrigation system. The fertilizer in drip irrigation method has almost no volatility and loss, is concentrated and has a low concentration, is safe and efficient, and saves labor and effort. It is suitable for areas with a high degree of agricultural modernization, and can provide comprehensive irrigation and save water resources.

3. Combined fertigation

Apply fertilizer while irrigating so that the fertilizer is incorporated into the soil along with the water. Combining fertigation with irrigation can improve fertilizer utilization, reduce fertilizer loss, and meet the crop's needs for water and nutrients.

4. Traditional watering and fertilization method

Fertilize first and then water, or fertilize and water at the same time. Watering should be done in moderation to avoid waterlogging in the soil, which would affect the respiration of the plant roots. Fertilization should be carried out according to the growth needs of crops and soil conditions to avoid excessive fertilization leading to excessive concentration of soil solution.

The above is the reason for watering when fertilizing farmland. Watering after fertilizing farmland is to reduce the concentration of soil solution and prevent plant cells from losing water. At the same time, it promotes the dissolution and diffusion of inorganic salts, improves the soil environment, and provides good conditions for the growth of crops.
