Solid fertilizers are dry and in form of pellets. Most Solid fertilizers are long-term slow-release fertilizers. Typically, used as basal fertilizers because the solid fertilizers have sufficient nutrients. After contacting with water, can continuously release nutrients to the soil over a long period. When applying solid fertilizers, should be placed away from the roots system to avoid direct contact, which may cause root burn. After applying, covered the fertilizer with soil or mixed into the soil.
However, because the absorption rate of solid fertilizers is not high, nutrients may not be completely absorbed by plants. With each irrigation and rainfall, fertilizers will easily be washed into nearby water systems or groundwater, causing environmental pollution.
Liquid fertilizer is a liquid concentrate that should de diluted with water before use. Most liquid fertilizer are quick-release fertilizers that can be directly applied to both leaves and soil after dilution. Through irrigation or foliar fertilization, it can immediately and effectively provide the nutrients to the plants, making up the poor absorption of roots. After use, it can significantly improve crop yield and quality. Liquid fertilizer has a more diverse nutrient than traditional solid fertilizers and can add multiple trace elements that are not easily absorbed by roots. Through efficient absorption by foliar fertilization, liquid fertilizer can quickly replenish the nutrients needed by plants at different growth stages.
When applying liquid fertilizer, it needs to be diluted and evenly sprayed on the plant leaves, stem or watered into the soil. However, depending on the method used, it is important to pay attention to the dilution ratio to avoid fertilizer burn. In addition, liquid fertilizer can be applied using deep application methods, it is a technique that allowing liquid fertilizer deep near the root system of the crops, thus improving soil quality and increasing land value.
Therefore, in the use of fertilizers, it is important to understand the soil conditions and the planted crops, then choose the appropriate ratio of fertilizers. Most people will apply long-release solid fertilizers as basal fertilizer before the planting season to provide the long-term nutrition. At different growth stages, will use liquid fertilizers with different functions to provide sufficient and comprehensive growth elements to the plants, to increase the crop yield and quality. |
