Farm fertilizer is a natural organic fertilizer, mainly used in the waste and organic matter of rural life, such as human and animal manure, plant residues, animal bone meal, etc. Compared with chemical fertilizers, farmyard fertilizers have the following characteristics:
1.Farmhouse fertilizer is a complete fertilizer, containing a variety of nutrients such as nitrogen, phosphorus, and potassium required for crop growth, as well as trace elements such as calcium, magnesium, and sulfur. These elements are important for the growth and development of crops and provide comprehensive nutritional support.
2.The nutrients in the farmyard manure are released slowly, so there are no problems such as root burning. At the same time, the organic matter in farm manure needs to be decomposed by microorganisms before it can be absorbed and utilized by crops, so it can improve soil structure, increase soil permeability and water retention capacity, and is conducive to the long-term healthy development of soil.
3.The organic matter in farm fertilizer can promote the reproduction and activity of microorganisms in the soil, increase the number of beneficial bacteria in the soil, and these microorganisms can secrete some hormones and nutrients that stimulate the growth of crops, which is conducive to the growth and development of crops.
4.The organic matter in farmyard fertilizer can also adsorb and fix heavy metal ions in the soil, reducing the heavy metal content in the soil, thereby reducing the harm to crops.
5.The microorganisms and organic matter in farmyard fertilizer can also inhibit the reproduction and activity of pathogenic bacteria in the soil, reduce the occurrence and spread of soil-borne diseases, and contribute to the healthy growth of crops.
In short, as a natural organic fertilizer, farmhouse fertilizer has many advantages such as rich nutrients, improving soil structure, promoting microbial reproduction and activity, reducing heavy metal hazards and inhibiting the reproduction of pathogenic bacteria. Therefore, we should vigorously promote and use farm fertilizer in agricultural production to promote the sustainable development of agriculture.
In practical application, the use of farmhouse fertilizer needs to pay attention to the following points:
1.Farm manure needs to be fully decomposed before it can be used, otherwise it will cause problems such as root burning of crops. The method of decomposition is to pile the farmhouse manure in a cement floor or mound, cover it with plastic film, and after fermentation at high temperatures, it is ready for use.
2.Farmyard fertilizer needs to be used in moderation, too much can lead to problems such as root burning, and too little can not meet the nutritional needs of crop growth. Therefore, the amount of fertilizer to be applied needs to be determined based on factors such as crop type, growth stage and soil conditions.
3.The nutrient composition of farmhouse fertilizer is relatively comprehensive, but different crops have different requirements for nutrients, so it is necessary to determine the type and proportion of fertilizer according to the fertilizer needs of crops.
4.The use of farm manure requires attention to hygiene and safety issues, avoiding the use of farm manure containing harmful substances and pathogenic bacteria, and at the same time properly disposing of waste and organic matter.
To sum up, as a natural organic fertilizer, farmhouse fertilizer has a variety of advantages and precautions for use. In agricultural production, we should choose the appropriate fertilization method and proportion according to the actual situation to promote the sustainable development of agriculture.
