Water is the carrier of fertilizer. Generally speaking, without the function of water, there will be no absorption of fertilizer. Water not only drives the nutrient cycle of the elements in the fertilizer in the plant body, but also supplements the crop's demand for hydrogen and oxygen. .

Instant fertilizer

Instant fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is easier to be absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be used for washing Facility agriculture, such as application, sprinkler irrigation, infiltration irrigation and drip irrigation, realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor.

Insoluble fertilizer

The absorption rate of insoluble fertilizers is low and the effect is slow. Insoluble does not mean insoluble. Although many elements are insoluble in water, they are soluble in acids and salts. When crops are in the dormant state, in order to prolong the duration of the fertilizer and avoid the "short, violent, and fast" fertilizers, manufacturers have adopted special processes to add slow-release factors or sulfur coatings in the fertilizers to control nutrient content Release rate, so it has a long-term effect, generally used as a base fertilizer.

Insoluble fertilizer

It refers to a fertilizer that is insoluble in water but soluble in acid and salt. It can be used as a base fertilizer but not a top dressing. For example, organic fertilizer made from weathered coal has an organic content of up to 70%, but if it is not treated by ammoniating or acidification, it cannot be fully absorbed and utilized only by relying on plant root secretions for decomposition. Therefore, the quality of a fertilizer cannot be judged solely by its content, but the source of its raw materials, the combination of elements, the process flow, and the absorption rate must be investigated.
