Organic fertilizer and inorganic fertilizer should be reasonable

First, the advantages of organic fertilizer and inorganic fertilizer mixed with the use of fertilizer is characterized by high nutrient content, fertilizer efficiency, but the short duration, nutrient singly, if mixed with organic fertilizer can take advantage of length. 1. Meet the needs of crops for various nutrient growth periods. 2, can improve fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil. After mixing with farmyard fertilizers, the contact area between fertilizers and soil can be reduced, thereby reducing the proportion of fertilizers fixed in the soil and increasing the effectiveness of nutrients. 3, can preserve nutrients, reduce loss, improve crop nutrient absorption. Fertilizer application will affect the absorption of nutrients and water by crops and accelerate the loss of nutrients. Mixing with organic fertilizers, for example, can promote the absorption of nutrients and moisture by crops. 4, can effectively regulate the soil pH, improve soil structure. In alkaline soils, single application of acidic fertilizers can lead to soil compaction and increased acidity. If used in combination with organic fertilizer, it can effectively regulate acidity and alkalinity. 5, can increase soil nutrients, improve soil vitality. Farmyard manure is an energy source for microbial life. Fertilizer is an inorganic nutrient for the growth and development of microorganisms. The combination of the two can promote the activity of microorganisms, thereby promoting the decomposition of organic fertilizers. Soil microbial activity can increase soil nutrients, increase soil vigor, and promote crop growth. Second, the scientific mix of organic fertilizer and inorganic fertilizer 1, human waste and ferrous sulfate with: Add 100 grams of human urine 500 grams -600 grams of ferrous sulfate, can make the human fecal urine ammonium carbonate into the nature Stable ammonium sulfate plays a role in keeping fertilizers and deodorizing and preventing nitrogen from evaporating. 2, human waste and superphosphate collocation: In every 100 kilograms of human excrement, add 5 kilograms of superphosphate, stir evenly and store 3 days - 10 days, can make the highly volatile ammonium carbonate in human excrement into the conversion Ammonium phosphate, which is stable in nature, thus increases phosphorus in human waste and urine. Nitrogen is preserved by phosphorus, and fertilizer efficiency is greatly increased. 3, plant ash and superphosphate with: 6 kg of plant ash to 30 kg of water soak, plus 2 kg of superphosphate, 6 hours after adding 100 kg of water and mix well, after leaving sediment to take clear liquid spray, can be obtained The same fertilizer effect as potassium dihydrogen phosphate. 4, heap fertilizer with ammonium bicarbonate: the weeds, plant stems, leaves, etc. into pieces, add 0.5% -1% of ammonium bicarbonate and human waste accumulation of urine, and then covered with mud seal, fully decomposed It has become a highly efficient biopotassium fertilizer. 5. Mix manure with superphosphate: Add 20% of superphosphate to the excrement removed from the livestock circle and mix it for 20 days. This will not only prevent the loss of nitrogen nutrient in manure, but also accelerate the decomposition of manure, increasing The content of available phosphorus.
