Monoammonium Phosphate For Plants

Product: Monoammonium phosphate for plants

Description: Monoammonium phosphate (MAP) is a fertilizer that provides essential nutrients for plant growth and development. It contains both nitrogen and phosphorus, two important nutrients that are required for healthy plant growth.

Molecular formula: NH₄H₂PO₄

How to apply to improve the utilization of MAP?
First, MAP should be mixed with organic fertilizer application.
Because MAP is easy to be fixed by the soil and cause mobility is not easy to be absorbed by the crop, phosphorus fertilizer mixed with organic fertilizers can reduce the fixed role of the soil on phosphorus, phosphorus to increase the mobility of the crop absorption and utilization. At the same time, the use of organic fertilizers can promote the activity of microorganisms in the soil, microbial activity is strong, and can promote the release of insoluble phosphorus in the soil, thereby increasing the amount of crop absorption and utilization.

Second, as a base fertilizer concentrated deep application.
Experimental practice has confirmed that calcium superphosphate concentrated deep application than sprinkler effect is good, that is, the phosphorus fertilizer is applied to the root part of the crop, to facilitate the root system to absorb and use. Generally used in the production of strip, such as the combination of spring sowing shallow plowing slip Shi, hole Shi, ditch Shi can be applied, so that the application of soil can make the fertilizer effect is concentrated, easy to crop absorption. In the base fertilizer should be applied up and down in layers to meet the crop seedling and mid-late demand for phosphorus fertilizer.

Third, according to the crop on the need for reasonable application of MAP.
Different crops on the sensitivity and absorption capacity of phosphorus fertilizer is very different. Block limit, tuber crops, beans, melons, fruit crops such as phosphorus demand, planting these crops should pay attention to more phosphorus. For water and drought crop rotation, phosphorus fertilizer should first be applied to dry crop. In the dry crop rotation, phosphorus fertilizer to focus on the autumn sowing crops, such as for wheat, corn rotation, to be mainly applied to wheat as base fertilizer, and corn is the use of its after-effects can be. For beans, grain crop rotation, phosphorus fertilizer should be reapplied to legume crops to promote nitrogen fixation, phosphorus to promote nitrogen.

Fourth, according to the soil phosphorus supply capacity to determine the amount of MAP.
According to the soil content of effective phosphorus to determine the amount of phosphorus fertilizer, generally effective phosphorus content in the 8rng/kg above the soil phosphorus effect is worse, so the soil effective phosphorus content of the plot should be less phosphorus fertilizer, and low phosphorus content of the soil phosphate fertilizer application to promote the growth of crops will be more obvious. Soil effective phosphorus content is the main factor in determining the effectiveness of phosphorus fertilizer, the general principle is the lack of phosphorus plots more phosphorus fertilizer, phosphorus-rich plots less, every other year or no phosphorus fertilizer.

Fifth, to be applied in conjunction with other elements of fertilizer, to avoid the single application of MAP.
MAP applied alone is not as effective as nitrogen fertilizer applied alone, so nitrogen fertilizer can be applied alone, and phosphate fertilizer is best applied with other elements of fertilizer formulas. Because the crop absorption of nutrients is comprehensive, according to the fertilizer law of crops, in accordance with a certain proportion of reasonable matching of nitrogen fertilizer, phosphate fertilizer, potash and other micronutrient fertilizers used together is the way of scientific fertilizer, so, regardless of whether the application of water-soluble phosphorus fertilizer or insoluble phosphorus fertilizers, only in the application of adequate fertilizer on the basis of the reasonable use of elemental fertilizers, in order to play the role of its yield increase.
