Organic fertilizer can be used year after year; long-term application is no problem
Organic fertilizer and chemical fertilizer used together complement each other, but if the combination is unreasonable, both will suffer damage and cause harm. 1. Benefits of mixing organic fertilizer and chemical fertilizer: 1. Making up for each other's shortcomings and building soil fertility. Chemical fertilizer has a single nutrient, high content, and quick effect, but a short duration; organic fertilizer has complete nutrients, a long-lasting effect, and can improve the soil...
Organic fertilizer can be used year after year because:1. Organic fertilizer itself contains a large amount of crop nutrient elements, and applying organic fertilizer is also returning nutrients to the soil.
2. After applying organic fertilizer, the soil's nutrient-holding capacity is improved, which can effectively reduce the loss of available soil nutrients.
3. Applying organic fertilizer can promote the reproduction and activity of microorganisms, enabling them to activate more elements in the soil that are difficult for crops to absorb and use.
Usually, fertilization also requires considering cost. For higher-income cash crops, continuous yearly use can be considered, but for grain crops, the cost of use should be appropriately considered.
