What is organic fertilizer (what does organic fertilizer provide for plant growth)

What is organic fertilizer?

Organic fertilizer refers to fertilizer containing organic matter . This type of fertilizer can be made and used locally in rural areas using various crop straws, natural weeds, animal and plant remains, garbage, etc. as raw materials.

Organic fertilizer is also called farmyard manure. There are many types of organic fertilizers. Organic fertilizers include compost made from human feces, livestock and poultry feces, crop straw, fermented manure and biogas fertilizer, and soil fertilizers including: wood ash, coal ash, garbage fertilizer, mud fertilizer, rock ash, lime, and gypsum .

Characteristics and functions of organic fertilizer

1. Comprehensive nutrition

Organic fertilizers have a great effect. First, organic fertilizers contain comprehensive nutrients. They contain both the macroelements necessary for crops and trace elements and growth stimulating substances, making them complete fertilizers.

2. Organic fertilizer contains a lot of organic matter

These organic matters play a unique role in improving soil properties, increasing soil fertility and eliminating soil pollution.

3. Organic fertilizers have a slow effect, but their fertility lasts long

Because most of the nutrients contained in organic fertilizers are in organic form, they need to be continuously decomposed and transformed by microorganisms before they can be absorbed and utilized by crops.

4. The quantity is very large and the cost is relatively low

Fourth, organic fertilizers are widely available, in large quantities, and at low cost. The production cost of using organic fertilizers is low and the profit is high.

However, the nutrient content of organic fertilizers is relatively low, and the preparation, storage, transportation and application of the largest amount of fertilizers are inconvenient.

【 Summarize 】

The use of organic fertilizers can not only ensure high and stable yields of crops, but also fertilize the soil.

Precisely because organic fertilizers have a great effect on improving soil and increasing production, we must vigorously strengthen the utilization of organic fertilizers in agricultural production. Fertilization should be based on organic fertilizers, supplemented by chemical fertilizers, and a combination of organic and inorganic fertilizers.
