1. Apply less fertilizer frequently. The nitrate nitrogen and ammonium nitrogen in the compound fertilizer will absorb part of the heat during the dissolution process, which may affect the ground temperature and cause adverse effects on the growth of crop roots. However, the normal growth of crops still needs sufficient supply of nutrients. Therefore, when applying the compound fertilizer in winter, it is necessary to apply less frequently and try to do so in the morning when the weather is fine.
2. Inorganic fertilizer should be applied in combination with pure biological fertilizer (without nitrogen, phosphorus and potassium). Long-term single use of chemical fertilizers will gradually consume the organic matter in the soil, resulting in the reduction of the number of beneficial microorganisms in the soil, the reduction of enzyme content, and the destruction of colloids, resulting in soil compaction, acidification, and salinization. NPK fertilizer and organic bio-fertilizer can improve the soil, reunite the sand, loosen the clay, inhibit the pathogenic bacteria, restore the micro-ecological environment in the soil, enhance the soil permeability, and improve the ability of retaining water and fertilizer. The fertilizer plant uses a disc granulator (https://www.organic-fertilizer-machinery.com/fertilizer-granulator-machine-series/disc-granulator.html) to process organic and inorganic fertilizers in order to improve fertilizer efficiency.
3. Fertilizer should be applied pertinently.
The npk fertilizer granulator (https://www.organic-fertilizer-machinery.com/fertilizer-granulator-machine-series/new-type-two-in-one-organic-fertilizer-granulator.html) manufacturer suggests that the fertilizer should be applied in a scientific way. According to the above principles, the organic and inorganic fertilizers should be used together to improve the agricultural income.
