1. Add a strong adsorbent substance such as fine soil or turf to human excrement. Human feces and urine have high nutrient content, rapid decomposition, and rapid fertilizer efficiency, but they are easy to lose. If the soil, turf and other substances with strong adsorption capacity are put into the septic tank as a covering or mixed in the excrement, it can absorb urine and Ammonia gas can greatly reduce nitrogen loss. According to the test, adding 25% of fine dry soil to human excrement can reduce nitrogen loss by 10%.
2. Add calcium superphosphate to human excrement. Adding 3% to 5% of superphosphate in human excrement can not only reduce nitrogen loss, but also increase nutrients such as phosphorus in human excrement.
3. Add ferrous sulfate to human excrement. 250-300 grams of ferrous sulfate is added to every 50 kilograms of human excrement, which is both nitrogen-protecting and deodorizing.
4. Add gypsum powder to human excrement. Add 5 kg of plaster and 25 kg of water per 50 kg of human excrement, mix well, and apply after 10 days of sealing.
5. Add soy flour to fresh cow dung. Add 50 grams of soy flour per 50 kg of fresh cow dung, mix well in a tank, seal for 3 to 5 days at 25 ° C, and apply 3 times of water when applied.
6. Add calcium superphosphate to the circle fertilizer. Add 2% of superphosphate in the circle fertilizer, stir it evenly and store it for about 20 days, and its fertilizer efficiency can be increased by more than 1 time.
7. The combination of farmyard manure and phosphate fertilizer can also increase the efficiency of phosphate fertilizer. This is because the carbon dioxide and organic acid produced by the farmyard fertilizer during the decomposition process contribute to the conversion of the poorly soluble phosphorus-containing compound in the phosphate fertilizer. At the same time, the humic acid in the farmyard manure has strong adsorption substitution performance and can be combined with the soil. Metal ions such as iron, aluminum, calcium, etc., which function as "fixed", combine to form a complex, thereby activating and protecting phosphorus and improving utilization. According to the research, the application of phosphate fertilizer and organic fertilizer after mixing and stacking can increase the utilization rate of phosphate fertilizer by 10%~30%; among them, the mixing of phosphate rock powder and manure fertilizer for 30 days can increase the weak acid-soluble phosphorus by 67.6%. Phosphate fertilizer and organic fertilizer are mixed and stacked, the proportion of adding superphosphate is generally 2% to 3%, calcium magnesium phosphate is about 5%, and phosphate rock is 5% to 10%.

SPC is defined as Stone Plastic Composite or Stone Plastic Composite. Using advanced technologies, it is made up of four layers – the top wear layer, a printed vinyl layer, a rigid core, and the final backing layer. The top two layers serve the same function as the popular vinyl flooring. The protective wear layer is crucial for the lifespan of your flooring, preventing excessive wear and tear. As its name suggests, the printed vinyl layer is manufactured with realistic images that mimic the look of materials like stone, ceramic, or wood.
