What is a macro-element water-soluble fertilizer? Here is a detailed introduction
A macro-element water-soluble fertilizer is a multi-nutrient compound fertilizer that dissolves completely in water. It dissolves rapidly in water, is more easily absorbed by crops, and its absorption and utilization rate is relatively high.
Macro-element water-soluble fertilizers are liquid or solid products that are dissolved or diluted in water for fertigation, foliar feeding, soilless cultivation, seed soaking and root dipping, and other uses.
Features of macro-element water-soluble fertilizers:
Macro-element water-soluble fertilizers can be used in facility agriculture such as sprinkler and drip irrigation, achieving integrated water and fertilizer management and saving water, fertilizer and labor. They can be used for foliar feeding, seed soaking and root dipping, and fertigation; fertigation includes fertilizing during sprinkler irrigation, drip irrigation and other irrigation methods, which saves water and fertilizer and is absorbed quickly by plants.
1. The raw materials are ultra-pure, free of impurities and low in electrical conductivity, and can be safely applied to various cash crops such as vegetables, flowers, fruit trees, tea, cotton, tobacco and turf;
2. It balances the ratio of the 15 elements required by plants and is developed using advanced TURBO manufacturing technology; it fully meets the needs of agricultural producers for high-quality, highly stable products;
3. It is completely water-soluble and of exceptionally high purity, suitable for all fertilization systems, and can be used for basal application, broadcasting with irrigation water, drip irrigation, sprinkler irrigation and foliar spraying; long-term application will not cause soil acidification or compaction;
4. It has good compatibility and can be mixed with most pesticides (except strongly alkaline pesticides), reducing operating costs;
5. Trace elements exist in the product in chelated form and can be fully and effectively absorbed by plants.
Application methods for macro-element water-soluble fertilizers:
Direct application with irrigation water:
Do not apply it directly with irrigation water the way you would with a compound fertilizer for broadcasting with irrigation water; instead, use the "double dilution" method of fertilizing with irrigation water. Some farmers apply water-soluble fertilizer directly with irrigation water the same way they apply ordinary compound fertilizer, resulting in uneven fertilizer distribution: vegetables that receive too much fertilizer suffer root damage and yellow leaves, while those that receive too little are affected in their growth. Water-soluble fertilizer has a higher nutrient content than ordinary compound fertilizer and is used in smaller amounts, generally 8-10 kg per mu. It is recommended that farmers make a fertilizing tank in advance with a switch at the bottom; before fertilizing, first dissolve the water-soluble fertilizer in the tank, calculate the fertilizer amount, open the switch, and let the fertilizer solution flow along with the irrigation water to fertilize. In addition, farmers can directly use an electric sprayer as the container for diluting the fertilizer solution to fertilize. The purpose of double dilution is to ensure even fertilizer distribution and improve fertilizer use efficiency.
Hole application method for water-soluble fertilizer:
When applying water-soluble fertilizer in holes, pay attention to the application rate. Hole application of fertilizer has the characteristics of concentrated application, high use efficiency and low fertilizer use, but many farmers are not sure about the amount of water-soluble fertilizer to use for hole application, resulting in root burn and seedling burn. Therefore, when applying water-soluble fertilizer in holes, be sure to pay attention to the application rate; for example, for a (20:20:20) water-soluble fertilizer, 3-5 grams per hole is appropriate, and it must be mixed evenly with the soil before planting seedlings.
Spraying method for water-soluble fertilizer:
When spraying water-soluble fertilizer, use it alone as much as possible, or mix it with non-alkaline pesticides. When vegetable crops show nutrient deficiency symptoms or poor root growth, many farmers choose to spray water-soluble fertilizer to alleviate the problem. It is recommended that farmers spray water-soluble fertilizer alone as much as possible, or mix it with non-alkaline pesticides, to avoid reactions between metal ions that produce precipitates and cause leaf fertilizer damage or pesticide damage.
Precautions for macro-element water-soluble fertilizers:
1. The water-soluble chelated trace element composition added to the ingredients should avoid antagonistic effects with phosphorus.
2. For crops, it has stress-resistant and yield-increasing characteristics, can significantly improve crop photosynthesis, raise crop yield and quality, increase sugar content, enhance cold resistance, drought resistance, disease resistance, lodging resistance and other stress resistance, and extend the fresh-keeping period.
3. The addition of a high-potassium formula can quickly meet the potassium demand of fruits, grains and other parts during expansion, increase fruit sweetness, improve fruit coloring and extend storage time.
