How to apply compound fertilizer for the best effect?

Compound fertilizer is often used as base fertilizer and topdressing. Compared with single fertilizers such as urea and potassium sulfate, compound fertilizer contains more types of nutrients, is more convenient to use, and is widely used in agriculture. So how to apply compound fertilizer to achieve the best effect? Let’s take a look with the editor below.

1. Choose suitable compound fertilizer

Choose appropriate compound fertilizer according to the type of crops planted and soil conditions. For example, nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer have different fertilizer effects, and the nutrient ratio of the selected compound fertilizer should be suitable for the needs of the crops.

2. Application method

① Application of base fertilizer

Before sowing or transplanting crops, spread the compound fertilizer evenly on the soil surface, then till and mix it into the soil. The amount of basal fertilizer applied should be determined based on crop demand and soil fertility level, generally accounting for 60%-70% of the total fertilizer application.

② Topdressing

During the crop growth period, apply compound fertilizer in a timely manner according to the growth conditions of the crops and changes in soil nutrients. Top dressing can be done by furrow application, hole application or foliar spraying to improve fertilizer utilization.

③ Combined application with water and fertilizer

Dissolve compound fertilizer in water and apply it to the soil through drip irrigation, sprinkler irrigation and other irrigation systems to achieve integrated water and fertilizer management. This method can save water resources and improve fertilizer utilization.

3. Notes

① Avoid excessive application: Excessive application of compound fertilizers may lead to soil salt accumulation and affect crop growth. The amount of fertilizer should be reasonably determined based on crop needs and soil fertility levels.

② Pay attention to the timing of fertilization: The timing of fertilization should be reasonable. Avoid fertilizing during the peak growth period of crops or during high temperature and drought to avoid root burn or waste of fertilizer.

③ Reasonably match with other fertilizers: Although compound fertilizers are nutritionally balanced, using them alone may not meet all the needs of crops. Therefore, other fertilizers, such as organic fertilizers , biological fertilizers , etc., should be reasonably matched according to crop needs and soil nutrient conditions.

④ Keep the soil moist: Compound fertilizer requires a certain amount of water during the process of dissolution and nutrient release. Therefore, the soil should be kept moist after fertilization to facilitate the dissolution of fertilizer and the absorption of nutrients.

The above is an introduction to how to apply compound fertilizer for the best effect. The characteristic of compound fertilizer is that it contains a lot of elements, and the amount of fertilizer applied should be determined according to the type of crop and soil conditions. When planting rice, about 50 kilograms are needed per acre, and peanuts generally require about 25 kilograms per acre.
