Monoammonium phosphate: composition and form of release, instructions for use

Nitrogen and phosphorus are the main nutrients of all plants, so many fertilizers contain them in a certain ratio. Consider the composition and form of release of monoammonium phosphate, where it is used, how and in what soils it should be used, the consumption rate. How to work with it according to safety precautions, is it compatible with other agricultural products, how to store and analogue fertilizers.

Composition and form of release of nitrogen-phosphorus fertilizer

Monoammonium Phosphate is available as a white crystalline powder in 25 kg bags. The share of nitrogen in the ammonium form is 12%, phosphorus is 61%.In MAF, nitrogen is in the ammonium form, phosphorus is predominantly in the form of diammonium phosphate. Among solid fertilizers, monoammonium phosphate has the highest content of phosphorus. Dry powder has a water content of not more than 0.3%, insoluble residue - not more than 0.1%. The acidity of the aqueous solution is pH 4.5.

Completely soluble in water, easily absorbed by plants, has a lower acidity value than urea phosphate. Phosphorus stimulates root growth, so it is advisable to feed young plants with monoammonium phosphate. Phosphorus uptake is improved by lowering soil acidity with ammonium nitrogen.

If you use monoammonium phosphate in tank mixes with other fertilizers, it can fully provide plants with good nutrition throughout the season. Can be used in drip irrigation systems, for foliar feeding (in solution), for making mixtures and suspensions.

Where is monoammonium phosphate used

You can fertilize any crops in agriculture: vegetables, flowers, garden trees and bushes, berries and ornamentals. This is an effective, high-quality and environmentally friendly fertilizer that can be applied to large and small farm plots and fields of agricultural enterprises.

Growing products using monoammonium phosphate becomes profitable from an economic point of view due to a reduction in the cost of fertilizers, protective agents, and other agrochemicals. The reason is the improvement in the condition of plants after feeding with monoammonium phosphate, its positive effect on their normal development and growth, the ability to resist diseases and pests, improving the quality of fruits and increasing the yield.

Fertilizer is non-toxic to plants, does not damage seedlings, so it can be placed with germinating seeds, the risk of damage from ammonia does not threaten them. The solution is also used together with irrigation in the fields, it can be used to water peat substrates if nitrification in them is slow.

Due to the highest percentage of phosphorus among mineral fertilizers, monoammonium phosphate is best applied in the early stages of plant growth for rapid root development.

Consumption rate and application

When applying monoammonium phosphate every 1.5-2 weeks, plants should be watered with a solution at a dosage of 20 g per 10 l for vegetables and flowers, 15 g per 10 l for ornamental and berry shrubs and for fruit trees. Consumption per hectare: 3-5 kg for potatoes and vegetables, 8-10 kg for fruit trees and vineyards.

Dosage of monoammonium phosphate for leaf feeding: 1%, that is, 1 kg per 100 liters of water, the number of sprays is 1-3. Can also be applied dry, surface or subsoil (incorporated by plowing).

Use in different soils

Monoammonium phosphate can be used on all types of soil, but the application has its own characteristics. The fertilizer itself is slightly acidic, so it is recommended to use it on neutral and alkaline soils.

Chernozem

On chernozem soils, fertilizer is used as the main fertilizer for cereals, root crops, potatoes, crops that do not like chlorine.

Carbonate chernozems

On such soils, monoammonium phosphate is considered more effective than complex fertilizers that contain nitrogen in the nitrate form.

Chestnut soils

Recommended to use this fertilizer in irrigation systems.

Saline soils

Shows good results on this type of soil, especially in irrigation systems. It is desirable to use for vegetables and industrial crops.

Safety

You need to work with monoammonium phosphate fertilizer in a respirator or mask, plastic glasses with side protection, ammonia vapors can severely irritate the skin and eyes.Do not remove until the end of work. In case of contact with the eyes and skin, immediately wash off the solution with plenty of water.

In case of poisoning due to ingestion, do a lavage: drink 1 liter of water and medical charcoal tablets, after 15 minutes. induce vomiting. If the condition does not improve or worsens, see a doctor.

Compatibility

Do not mix a concentrated solution of monoammonium phosphate fertilizer in the same solution with preparations containing calcium and magnesium s alts. In other cases, you need to check the joint action by mixing the components in a small volume in a separate container. If a chemical reaction does not take place, a general solution can be prepared. If there is a noticeable change in temperature, color, consistency of the liquid, you should choose another component.

Storage and analogues

It is afraid of dampness, so you need to store it in factory-made polyethylene bags in a dry, ventilated room where moisture and direct sunlight do not get.Do not store outside. Bags must be tightly closed and not damaged. Monoammonium phosphate refers to fire and explosion-proof mixtures. Due to the addition of conditioning additives, it does not cake.

You can put other fertilizers and pesticides next to it. Do not store food, medicines and household products, livestock feed. Do not allow children and animals to come into contact with the fertilizer or its solution. Guaranteed shelf life from the manufacturer - 6 months. So much time the fertilizer is stored without loss of properties, if the rules of conservation are violated, it loses its effectiveness earlier. When wet or absorbing moisture, it dissolves and then hardens.

You can replace monoammonium phosphate for plant nutrition with fertilizers: Ammophos, Suprefos, Nitroammophos, Valagro MICRO NP, Diammonium phosphate, Grosdorf ZhKU 8:24:0, Yara Krista MAP, B altic-Terra nitrogen-phosphorus brand 16:20 and others.

Monoammonium phosphate is an effective nitrogen-phosphorus fertilizer for agricultural enterprises, a powder containing nitrogen and a high percentage of phosphorus.It does not contain chlorine, heavy metals, sodium, and other impurities. Plants fed with this fertilizer quickly assimilate the elements, they improve their growth and development. Uniform application can be achieved by fertilizing crops through drip irrigation systems or by spraying the solution over the leaf. This is a fast-acting, environmentally friendly and high-quality nitrogen-phosphorus fertilizer that can be used for fruits, vegetables, shrubs, flowers, grains on all types of soils. Thanks to the use of this fertilizer, growing crops becomes more profitable, and the cost of production is reduced.
