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 fertilizers 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 it, improve water retention, and promote microbial activity. It also helps in making the soil more fertile over time. For more information, visit our company at **http://**
In addition to improving soil quality, organic fertilizers can boost crop yields and enhance the quality of agricultural products. They contain not only essential nutrients like nitrogen, phosphorus, and potassium but also other valuable substances such as amino acids, sugars, and trace elements. These components provide essential nutrition to plants while also stimulating beneficial microbial activity in the soil. For example, livestock manure contains various minerals, including boron (2.2–2.4 g per 100 kg), zinc (2.9–29.0 g), manganese (14.3–26.1 g), molybdenum (0.3–0.4 g), and available iron (2.9–29.0 g). When combined with chemical fertilizers, organic fertilizers can significantly increase yield, improve product quality, reduce nitrate and nitrite levels in vegetables, and enhance vitamin C and sugar content in fruits.
Different types of organic fertilizers serve different purposes. Some are mainly used to improve soil structure, such as straw, peat, and compost, while others are primarily for supplying nutrients to crops, like human waste or chicken manure. The difference lies in the ratio of organic matter to nitrogen, known as the carbon-to-nitrogen (C/N) ratio. Fertilizers with a C/N ratio above 30 are ideal for soil improvement, while those with a lower C/N ratio are better suited for providing plant nutrients. For instance, crop straw has a C/N ratio of around 100, making it highly effective for soil enhancement. However, due to its low nitrogen content, it may temporarily absorb nitrogen from the soil during decomposition. Therefore, when returning straw to the field, it's advisable to add some chemical nitrogen fertilizer to speed up the decomposition process and prevent nitrogen deficiency in crops.
