Granular water-soluble fertilizer, an innovative form of water-soluble fertilizer, is unique in that the water-soluble fertilizer is refined into granules. Although it appears as granules, it can be quickly and completely dissolved in water without residue, and the nutrients are balanced.
This fertilizer is not only easy to use, but also easier for plants to absorb. So, how can we use granular water-soluble fertilizer correctly?
- Use as base fertilizer
Granular water-soluble fertilizer can be mixed with compound fertilizer, organic fertilizer, etc. at will, and play an excellent regulating role. It can effectively regulate the soil with acid-base imbalance, improve the absorption and utilization rate of nitrogen, phosphorus and potassium through the process of nitrogen fixation, phosphorus dissolution and potassium activation, and provide crops with lasting fertilizer effect.
- Use in hole application or furrow application
Granular water-soluble fertilizer can be used in hole application or furrow application, which can fully and quickly supplement the required nutrients for crops, promote rooting and strong plants, and increase the emergence rate.
- Root irrigation after dissolution
It is also a good choice to dissolve the granular water-soluble fertilizer and then irrigate the roots. Use it in appropriate amounts according to the size of the plant, which can quickly achieve the effect of rooting and strengthening the tree, while stimulating root growth, enhancing tree vigor, and improving resistance.
- Spreading granular water-soluble fertilizer
Spreading granular water-soluble fertilizer is also very convenient, for example, directly spreading it on the ground before the rain. This method of use is particularly popular in areas such as tea and fruit trees. It can quickly solve the problem of leaf yellowing and nutrient deficiency, and quickly replenish the nutrients such as nitrogen, phosphorus, potassium, trace elements, and amino acids required by crops.
- Large-scale water flushing or flooding
If granular water-soluble fertilizer is used by large-scale water flushing or flooding, long-term use can further regulate the acid-base imbalance of the soil, promote the rooting of the main root and the growth of hair roots, thereby increasing the flowering and fruiting rate and fruit enlargement.
- Drip irrigation, sprinkler irrigation and soilless cultivation
Drip irrigation, sprinkler irrigation and soilless cultivation are also applicable methods for granular water-soluble fertilizer. In Xinjiang’s cotton region, drip irrigation and other integrated water-fertilizer facilities widely use granular water-soluble fertilizers, which not only save water, fertilizer and labor, but also improve fertilizer absorption and utilization, resist adversity, frost and repeated cropping, and promote flower bud differentiation and increase yield.
- Foliar spraying
In addition, granular water-soluble fertilizers can also be used by foliar spraying. For example, on fruit trees, they can be diluted and sprayed according to the situation, and when spraying vegetables, a few granules can be dissolved and used as foliar fertilizers. This can quickly solve the problem of weak leaves and tree vigor, make the leaves more dense and thick, and improve photosynthesis efficiency.
In short, granular water-soluble fertilizers, as an emerging category of fertilizers, are unique in the fertilizer industry. Its notable features include comprehensive nutrients, high utilization rate, rapid dissolution and diversified use methods. The emergence of this innovative product breaks the single limitation of the use of traditional compound fertilizers and water-soluble fertilizers, and brings growers a new fertilization experience that saves labor, time and money. Whether it is greenhouse vegetables, fruit trees, flowers or field crops, granular water-soluble fertilizers can be used, and the use methods are flexible and varied to meet the fertilization needs of different regions and crops.
However, with the rapid development of the granular water-soluble fertilizer market, product quality issues have gradually emerged, and it is difficult to distinguish between true and false. Therefore, when choosing, it is necessary to conduct a comprehensive evaluation of the product’s appearance, smell, solubility, packaging, and sales channels to ensure that you purchase high-quality granular water-soluble fertilizers.
Next, we will compare and analyze ordinary compound fertilizers with high-quality granular water-soluble fertilizers. Ordinary compound fertilizers are mostly made of potassium sulfate or potassium chloride, urea, monoammonium, etc., and granulated by extrusion, roller, spraying or high tower technology. However, this type of fertilizer has a high salt index, contains biuret, is not safe, and has an utilization rate of only about 30%. In addition, it has poor water solubility, is prone to precipitation after melting, and is not suitable for drip irrigation. The absorption of compound fertilizers in the soil is also relatively slow.
In contrast, high-quality granular water-soluble fertilizers such as Mahim’s enzyme granular macronutrient water-soluble fertilizers show significant advantages. Its ratio is more reasonable, containing high concentrations of nutrients, which can supplement macro, medium and trace elements at the same time to ensure comprehensive nutrition. The product has a low salt index, and the aqueous solution does not precipitate after long storage, which can effectively alleviate the salt content of the soil. The use of potassium dihydrogen phosphate as a raw material makes it excellent in water solubility, quick dissolution and long-lasting, with a fertilizer effect period of up to 60 days. The hardness and nutritional balance of the compound fertilizer particles are further improved through high-tower granulation technology. In addition, the use of double-chelating technology not only enhances the stability of various nutrients, but also improves the utilization rate of fertilizers, while helping to improve soil and crop root development, thereby improving crop quality and yield. In addition, the bacterial enzyme humic acid added to the product is carefully developed through microbial fermentation technology, which can effectively fertilize the soil and improve fertilizer efficiency.
