Can the bought organic fertilizer be directly mixed with the soil? What should be paid attention to in application?

In agricultural farming, fertilization is an essential part, and the application of organic fertilizer can constantly provide nutrients to crops. Can the bought organic fertilizer be directly mixed with the soil? What should be paid attention to in application?

Can the bought organic fertilizer be directly mixed with the soil?

The bought organic fertilizer had better be the territory before use, so as to avoid the situation of root burning caused by improper application. In addition to buying organic fertilizer from outside, qualified friends can also make their own organic fertilizer.

1. High temperature composting

Using crop stems or weeds, fallen leaves, swamp residues as the main body of composting, compacting the ground in front of the pile, laying dry fine soil about 10 cm thick to absorb fertilizer. Then add appropriate amount of nitrogen fertilizer and microbial preparations to replenish enough water. Finally, covered with mud seal or agricultural film, it can be used as organic fertilizer within 1 to 2 months.

two。 Common compost

Choose the place close to the water source, the transportation is convenient. Lay a layer of dry soil on the ground, and then cover it with compost materials including straw, human and animal manure and fine soil. After mixing according to the proportion of fertilizer, the adjusted moisture is about 50 inches wet weight. Finally, seal the mud 3-5 cm, carry on each other, and wait for the straw to be completely decomposed before use.

3. Soaking liquid fertilizer

Put the waste vegetable leaves, melon peel, viscera of chicken and fish, fish scale broken bones, eggshells and moldy food (peanuts, melon seeds, beans, etc.) into a small jar or small jar or even a wide mouth bottle, add water (you can sprinkle some pesticides under certain conditions), cover it strictly, and ferment and mature (about 2 ~ 3 months) (if the temperature is high, the time can be shortened and diluted with water, take the supernatant, and use it as topdressing).

The third method is recommended when making organic fertilizer for bonsai plants.

What should we pay attention to in the application of bought organic fertilizer?

1. Pay attention to ensure that it is used after maturity

Unripe organic fertilizer contains harmful substances such as pathogens and weed seeds, which may cause pest breeding, weed spread, crop seedling burning and other problems after application, which should be paid enough attention.

two。 Pay attention to mastering the application method

Organic fertilizer can be divided into solid organic fertilizer and liquid organic fertilizer. Generally, solid organic fertilizer is used as base fertilizer and liquid organic fertilizer is used as topdressing fertilizer. In the application method, powdered organic fertilizer can be applied before tillage, granular organic fertilizer can be applied, and liquid organic fertilizer can be sprayed, irrigated or dripped at different stages of crop growth, combined with solid organic fertilizer to provide nutrients for crops.

3. Pay attention to the scientific determination of application amount

The application rate of organic fertilizer should follow the principle of soil testing and formula fertilization, and formula fertilization should be carried out according to soil nutrient content, target yield and fertilizer nutrient content. In general, field crops apply 300,500kg of solid organic fertilizer per mu, vegetables and fruit trees apply 500kg / mu of solid organic fertilizer, and organic fruit and vegetable crops apply 1000-2000 kg of solid organic fertilizer per mu. The application of liquid organic fertilizer is determined according to different crop types and different production stages, and generally increases with the seedling stage, stem and leaf growth stage and fruit growth period.

Although the nutrition of organic fertilizer is more comprehensive, but it is not easy to decompose, can not meet the high yield of crops and other shortcomings, so do not think that the use of organic fertilizer is foolproof, the use of fertilizer should not be less.
