What are the reasons why applying more organic fertilizer can increase yield

In the process of agricultural planting, sometimes in order to increase yield and maintain quality, farmers usually apply more organic fertilizer. Why can applying more organic fertilizer increase crop yield?

1. Reasons why applying more organic fertilizer can increase yield

Applying more organic fertilizer can increase yield because organic fertilizer contains organic matter and humus, which can improve soil structure, raise soil fertility, increase soil temperature, air permeability and water-holding capacity, and provide the nutrients crops need, thereby improving crop quality and promoting high and stable yields.

2. Types of organic fertilizer

Organic fertilizers cover a wide range, have broad sources and many varieties. According to the same or similar production environments or application conditions, similar properties and functions, and composting methods, they can be roughly divided into several major categories: manure and urine fertilizer, compost and waterlogged fertilizer, straw fertilizer, green manure, soil and miscellaneous fertilizer, microbial fertilizer, etc.

3. Identifying bio-organic fertilizer

Check whether the packaging is standard. Check whether the upper right corner of the packaging has the Ministry of Agriculture microbial fertilizer registration certificate. Check whether the upper part of the packaging has the technical index for the number of effective viable bacteria. Check whether the lower part of the back of the packaging states the product shelf life.

Check whether the product is uniform. Based on moisture content for reference, grab a handful of fertilizer and observe in sunlight whether the material is damp and dark, and run it through your hands to see whether there is dust.

When applying fertilizer, it should be done according to the needs of the crops you are growing, and the amount used should be moderate.
