The Role of Organic Fertilizer in Rice and the Detailed Application Rate per Mu

Organic fertilizer not only provides comprehensive nutrition for crops, but also has long-lasting fertilizer effects, and is the main nutrient source for green food production. Applying organic fertilizer to rice can ensure increased fertilizer efficiency and stable yield and quantity. So what exactly is the effect of organic fertilizer on rice? How much should be used per mu? Let's find out next.

What is the effect of organic fertilizer on rice?

1. Organic fertilizer has a wide range of raw material sources and can be sourced locally and composted on site. It only takes labor and requires little capital investment, can save chemical fertilizer, and reduces production costs.

2. Organic fertilizer contains a variety of nutrient elements. In addition to major elements such as nitrogen, phosphorus, and potassium, it also contains many secondary elements and trace elements needed by crops, and can provide rice with comprehensive required nutrition, especially trace element nutrition. At the same time, it can improve the quality and palatability of rice.

3. Organic fertilizer contains organic matter and humus, can improve soil structure, coordinate soil water, fertilizer, air, and heat, and enhance the soil's air and water permeability as well as its ability to retain fertilizer, retain water, supply fertilizer, and supply water.

4. Organic fertilizer contains organic substances such as auxins, vitamins, humic acid, and amino acids, can play a special role in the nutritional physiology and biochemical processes of rice, and can also provide carbon dioxide gas for rice photosynthesis.

5. Organic fertilizer has a large buffering capacity, can moderate changes in soil acidity and alkalinity, and can eliminate or reduce the harm of saline-alkali soils to rice.

6. Organic fertilizer has wide applicability and is suitable for all types of soil and various crops.

How much organic fertilizer should be applied per mu for rice?

It depends on what kind of organic fertilizer is used. Generally, 150-200kg per mu is enough. For things like livestock and poultry manure, several tons are needed to promote root growth. If some bio-organic fertilizers or high-efficiency organic fertilizers such as carbon-based fertilizer are used, they are mainly used to increase the organic matter in the soil; organic fertilizer releases nutrients slowly and improves the soil's granular structure.

How do you identify whether organic fertilizer is good or bad?

1. Look: Look at the appearance and color of the organic fertilizer. Organic fertilizer dried by physical methods still retains the color of the original manure, only with reduced moisture. Organic fertilizer treated by composting technology turns brown or dark brown after decomposition, and there are no other impurities in the finished product.

2. Touch: Grab a handful of high-quality organic fertilizer with your hand. It feels consistent, soft and elastic when wet, and very brittle and easy to break when dry. With inferior organic fertilizer, you can feel impurities by hand, especially sand.

3. Soak in water: Take two cups of clean water and put some high-quality and inferior organic fertilizer into them respectively. The authenticity can be distinguished within a few minutes. Adulterated organic fertilizer is generally mixed with sand or soil to increase weight. High-quality organic fertilizer is evenly distributed in the water, while a lot of sand or soil sinks to the bottom of the cup with inferior organic fertilizer, making the difference obvious.
