(FAQ)Pig, cow, chicken, and sheep manure: Which soils suit each organic fertilizer?

Organic fertilizer production lines processed from various types of livestock and poultry manure differ in nutrient content and physical properties, yielding vastly different results when applied to the soil. Choosing the right type ensures the best results with optimal effort. 1.Pig Manure Organic Fertilizer: Suitable for Heavy, Compacted Soils Once decomposed, pig manure is slightly acidic with a fine texture and strong water and nutrient retention capabilities. It is particularly effective for improving heavy, prone-to-compaction red/yellow soils or alluvial soils, as it increases soil aggregation and improves permeability. Application rates should be controlled in sandy soils to prevent nutrient leaching. 2.Cow Manure Organic Fertilizer: Suitable for Poor Sandy Soils and Land Improvement Cow manure decomposes slowly and provides long-lasting fertility; it is rich in organic matter but relatively low in nitrogen and phosphorus. It is ideal for sandy soils, newly reclaimed land, or barren areas, significantly enhancing water and nutrient retention as well as soil buffering capacity. In heavy soils, its fibrous content helps loosen the soil structure. 3.Chicken Manure Organic Fertilizer: Suitable for Mature Soils Deficient in Phosphorus and Potassium Chicken manure is a high-nutrient fertilizer; it boasts the highest nitrogen, phosphorus, and potassium content among livestock manures and acts quickly. It is well-suited for mature loam or vegetable garden soils that lack phosphorus and potassium, yielding excellent results for fruits and vegetables. However, due to high salt and uric acid levels, caution is advised when using it on saline-alkali land or in greenhouses with continuous cropping to prevent salt accumulation. 4.Sheep Manure Organic Fertilizer: Suitable for Acidic Soils and Orchards Sheep manure is classified as a "hot" fertilizer; after decomposition, it is slightly alkaline and rich in calcium and magnesium. It is excellent for improving acidic soils, as it neutralizes acidity and replenishes calcium, while its loose texture facilitates deep-soil improvement. There is no "universal" organic fertilizer—only the "right match." It is recommended to apply fertilizer scientifically based on soil test results and specific planting needs to achieve a virtuous cycle of land utilization and soil health maintenance.
