Organic fertilizers play a crucial role in sustainable agriculture. One of their main benefits is improving soil structure and fertility. The primary component of organic fertilizer is organic matter, which, when applied to the soil, increases its organic content. This organic matter enhances the physical, chemical, and biological properties of the soil, helping to loosen the soil, improve water retention, and promote microbial activity.

In addition to improving soil quality, organic fertilizers can significantly increase crop yields and enhance the quality of agricultural products. They contain amino acids and other beneficial substances that are not only rich in nutrients but also stimulate the activity of soil microorganisms. These fertilizers also provide essential trace elements such as boron, zinc, manganese, molybdenum, and iron. For example, livestock manure contains about 2.2–2.4 grams of boron, 2.9–29.0 grams of zinc, 14.3–26.1 grams of manganese, 0.3–0.4 grams of molybdenum, and 2.9–29.0 grams of iron per 100 kilograms. When combined with chemical fertilizers, organic fertilizers have a significant impact on increasing yield, improving product quality, reducing nitrate and nitrite levels in vegetables, and boosting vitamin C and sugar content in fruits.
Different types of organic fertilizers serve different purposes. Some are primarily used for soil improvement, such as straw, peat, and compost, while others are mainly for supplying nutrients to crops, like human waste or chicken manure. The distinction depends on the ratio of organic matter to nitrogen in the material, known as the carbon-to-nitrogen (C/N) ratio. Organic fertilizers with a C/N ratio above 30 are best suited for soil improvement, while those with a C/N ratio below 30 are more effective as nutrient sources. For instance, crop straw has a C/N ratio of around 100, making it very effective for soil enhancement. However, because it contains low nitrogen, it may absorb nitrogen from the soil during decomposition. To speed up the breakdown process, it’s recommended to add some chemical nitrogen fertilizer when returning straw to the field.
