Grass ash and farmyard manure can be used together under certain conditions, and this mixed use helps to improve soil fertility, promote crop growth, and increase yield. The following is a detailed analysis of this issue: 1. Characteristics of plant ash and farmyard manure
1. Grass ash: Grass ash is the residue of plants (herbaceous and woody) after combustion, containing abundant potassium and various trace elements, and is a typical alkaline fertilizer- The main component of plant ash is potassium carbonate, which has a high potassium content and is mostly soluble in water, making it easy for crops to absorb- Grass ash also has various functions such as regulating soil pH, sterilizing and disinfecting, and promoting rooting.
2. Farm manure: Farm manure mainly includes human manure, manure, compost, etc. It is an organic fertilizer- Farm manure contains abundant organic matter, nitrogen, phosphorus, potassium and other elements, as well as various trace elements, which can comprehensively meet the nutritional needs of crops- The organic matter in farmyard manure is decomposed by microorganisms in the soil, which can enhance the soil's water and fertilizer retention capacity and improve soil structure. 2、 The advantages of using a mixture of plant ash and farmyard manure
1. Improving soil fertility: The combination of potassium in plant ash and organic matter, nitrogen, phosphorus, and other elements in farmyard manure can provide more comprehensive nutrition and help improve soil fertility- The alkalinity of plant ash can neutralize acidic substances in the soil, regulate soil acidity and alkalinity, and make the soil more suitable for crop growth.
2. Promoting crop growth: The potassium element in plant ash plays an important role in the root growth and stress resistance of crops, while the organic matter and trace elements in farmyard fertilizers can promote the overall growth of crops- The combination of the two can accelerate the absorption and utilization of nutrients by crops, improve their growth rate and yield.
3. Increasing yield: By improving soil environment and providing comprehensive nutrition, the mixed use of plant ash and farmyard manure can help increase crop yield and quality. 3、 Precautions for mixed use
1. Mixing ratio: The mixing ratio of plant ash and farmyard manure should be reasonably determined based on soil conditions and crop needs to avoid nutrient imbalance caused by excessive use.
2. Application method: Plant ash should be avoided from being mixed with ammonium nitrogen fertilizers (such as ammonium bicarbonate, ammonium sulfate, etc.) as much as possible to prevent ammonia volatilization loss- Farm manure should be fully decomposed before application to reduce the harm of bacteria and insect eggs to crops.
3. Soil conditions: For alkaline soil, the use of plant ash should be appropriately reduced to avoid exacerbating soil alkalization.
Grass ash and farmyard manure can be used together, and this mixed use method has significant advantages in agricultural production. However, attention should be paid to factors such as mixing ratio, application method, and soil conditions during use to ensure efficient use of fertilizers and healthy growth of crops.
