Monopotassium phosphate: fertilizer application for growing various crops

Potassium monophosphate is a quick way to make up for the deficiency of phosphorus and potassium. The additive is used for garden, ornamental and horticultural crops. Fertilizer refers to the complex. The use of potassium monophosphate helps increase yields. Fruits when using a chemical become better.

Monopotassium phosphate – what kind of fertilizer

Potassium monophosphate is a complex fertilizer. You can use the mixture for both foliar and root phosphorus dressings. Also, monopotassium phosphate is possible for use in drip irrigation of various crops. It has no nitrogen among other additives. Similar to superphosphate.

The additive mixes easily with water and does not contain any harmful components. Potassium with its properties improves metabolic processes in plant tissues.

Potassium monophosphate is produced in the form of a white powder of high concentration. Sometimes also fertilizer can be found in the form of granules. They are also used for mixing with water.

The composition of the mixture with potassium includes about 33% potassium and 50% phosphorus. Also in the preparation there is phosphoric acid. The additive belongs to mineral fertilizers. Due to the absence of nitrogen and other properties, it can be used for hydroponics.

The tool with potassium is combined and its use helps to increase the level of productivity. The chemical increases the amount of vitamins in fruits if used for vegetables. An additional advantage will be an increase in the shelf life of the crop and acceleration of its growth.

After treatment with potassium monophosphate, the plant becomes more resistant to various diseases and pests. The main feature of the drug with potassium is its versatility. The tool is equally effective in relation to both garden and indoor crops.

The chemical allows the plant to endure the winter well. It increases the resistance of the plantation to sudden changes in temperature and frost. Fertilizer is applied directly to the soil. The additive passes through the entire root system of the plant. Can also be used for foliar irrigation.

Fertilizer is usually used at the stage of planting seedlings in a permanent place, during flowering, and also after it ends. The tool is quickly absorbed and actively manifests itself when used on beds with any plants.

Under the influence of potassium monophosphate, a large number of side shoots are formed. In this case, many flower buds are formed in fruit-bearing species. Over time, they form fruit ovaries, thereby increasing productivity.

Potassium monophosphate is well absorbed by any parts of the plant. In this case, even if there is an overabundance of the additive, the plant will not suffer. Excess potassium will simply remain in the ground, making it more fertile.

If necessary, the chemical can be combined with any other medicines.

Pros and cons of fertilizer

Before using the tool, it is necessary to evaluate the existing advantages and disadvantages. Often, the use of monopotassium phosphate in agricultural technology is more than justified. The benefits available include:

1. The ratio of active ingredients. The amount of potassium and phosphate is optimal for good fruiting. The composition helps to resist diseases, pests and frosts.
2. Fertilizer promotes the formation of new side shoots. Not all chemicals activate their formation. This factor is especially important for flowers that need peduncles.
3. good solubility. The preparation with potassium is perfectly soluble in water, which makes it possible to make the most effective working solution. Active substances are characterized by rapid migration.
4. Possibility of assimilation by different parts of the plant. Thanks to this, top dressing provides a quick replenishment of the lack of trace elements. Excess potassium remains in the soil.
5. Inability to refeed. Potassium monophosphate is considered one of the most harmless dressings. Even if you add an excess of the substance, the representative of the flora will not suffer. The excess of the substance will remain in the soil, making it more fertile.
6. Compatibility with pesticides. With them, you can even prepare a single tank working solution for complex processing. This is a good option for complex processing.
7. Efficacy of potassium monophosphate against powdery mildew. The drug can be used both for treatment and prevention. Also top dressing copes with some fungal diseases.
8. No effect on soil acidity.
9. Complete absence of side effects.
10. positive effect on the ground. If this substance is regularly sprayed, then, for example, the drying of the earth in a greenhouse with sufficient irrigation is excluded, which is a frequent problem. The working solution normalizes the amount of soil microflora.

The disadvantage is the relative high cost. It is easily compensated by a number of positive properties. However, there are other disadvantages:

1. Potassium does not accumulate and quickly breaks down. Be sure to prepare the solution. It is useless to pour the drug in the form of a powder.
2. The impossibility of using the product in preparing plantings for winter. The maximum efficiency is observed in the summer.
3. The need to be ready for weed control after application. Top dressing accelerates the growth of weeds in the area.
4. Inability to combine potassium monophosphate with magnesium-based fertilizers. This limits the list of crops in the beds with which the additive can be sprayed.
5. The use of a granular additive on slow growing dormant houseplants is undesirable. The composition of the fertilizer is too active for them.

Important. Before using the composition, it is imperative to correlate the advantages and disadvantages, determining the appropriateness of using monopotassium phosphate in each individual case.

Compatibility

Potassium monophosphate in granules is compatible with any nitrogen fertilizers. It can be used for mixing in tank solutions. In this case, it is compatible with urea.

The drug can be used in conjunction with pesticides and fungicides. If an increased dose of calcium is needed in summer, then calcium sulfate is additionally used.

Monophosphate is not suitable for use with magnesium and calcium fertilizers. Compatibility, unlike nitrogen solutions, is extremely low.

Monopotassium Phosphate and Monopotassium Phosphate – What’s the Difference?

On the shelves of garden stores you can find both potassium monophosphate and potassium monophosphate. In fact, it’s one and the same. From a chemical point of view, the name potassium monophosphate is considered more correct.

Different names for the same fertilizer with phosphorus are marketing tricks. Often, manufacturers change the name of solutions to stand out from the competition.

Why and when is monopotassium phosphate used?

The product is used as a foliar fertilizer with phosphorus. It is suitable for both open and closed soils. Effective feeding:

• after picking at the time of transplanting seedlings;
• when feeding ornamental plants at the time of flowering, and fruit plants after fruiting;
• at the time of treatment of the plant from powdery mildew;
• when mixing complex mixtures for shrub and other plantations;
• for manual processing of medium and small areas.

Potassium monophosphate is considered a universal drug. It can be used in the processing of ornamental, fruit and vegetable crops.

The use of the drug is indicated when planting seedlings in a season with favorable weather. In unfavorable weather, transplanting plants into open ground is delayed. In this case, it is desirable to provide a normal amount of nutrition and add root.

You can use a spray with phosphorus for the purpose of abundant flowering and reducing the number of fallen ovaries. This will help increase productivity. Also, potassium monophosphate can be used for abundant flowering in ornamental plants in open ground.

In the case of houseplants, potassium monophosphate is used for emergency top dressing of plants with brown leaves.

Safety precautions for use

Spray chemicals must be used with care. Be sure to use personal protective equipment. It is recommended to wear gloves, goggles, a respirator. This will make it possible to protect the skin and mucous membranes.

Important. In case of accidental contact, wash off the chemical with plenty of water. Then you will need to seek help from a doctor.

Instructions for use of monopotassium phosphate

Top dressing can be used for both plants grown in open ground and those grown in a greenhouse. Before use, it is recommended to carefully read the instructions. The solution is prepared with the right amount so that the consumption is economical.

The exact dosage directly depends on which plant will be fed. The preparation is used for watering the soil or irrigating ground parts. Processing is carried out in the evening. This will slow down the evaporation process. Also, the solution can be used in installations on the ground for drip irrigation.

For tomatoes

Tomatoes of any variety are fed twice after planting in open ground for a large harvest of fruits. Between procedures make a two-week break. So the processing of tomatoes is most effective.

For each bush of tomatoes pour 2,5 liters of solution. The recommended dosage is 15 g per 1 bucket of water. You can also periodically spray the tomatoes with a working fluid.

For cucumbers

For cucumbers, regardless of the variety, top dressing is carried out in the same way as for tomatoes. The number of procedures for bushes is 2 with a break of 2 weeks.

Important. When making foliar dressings in cucumbers, you need to carefully monitor the fruits. If they are elongated, curved, then there is a lack of potassium. It is necessary to treat the vegetable by spraying to improve the quality of the fruit. Only after that it will be possible to carry out top dressing of cucumbers by watering.

For seedlings

Seedlings are fertilized when the first 2-3 leaves appear. Repeated use is indicated after 2 weeks.

The introduction of potassium monophosphate will allow crops:

• uniformly and fully form the root system;
• prevent stretching;
• stimulate growth.

The optimal dosage is 5 g per bucket of water.

For garlic

Garlic is fed by spraying. Fertilizer watering leads to excessive growth of the rhizome.

The recommended concentration of the solution is 0,02-0,05%.

For strawberries

Strawberries are fed mainly by watering. Unscheduled fertilization occurs in harvest years or after heavy rains.

When processing berry beds, they try to get as much solution as possible on the back of the sheets. The procedure is carried out after 2 hours after a good moistening of the earth.

The recommended dosage is 20 g per 1 bucket of water.

For potatoes

Potatoes are fertilized by spraying. Watering increases root growth, making potato tubers small and tasteless.

The recommended concentration of the solution is 0,02-0,05%.

For pepper

Spraying is carried out on the leaves. The recommended frequency of use in the garden is 2 times a season.

Add 20-50 g of the substance to a bucket of water for processing.

For flowers

Flower processing is carried out at the time of bud opening and when the culture enters the phase of abundant flowering. In a favorable year, early flowering can be achieved by watering the sprouts with a solution at the stage of 3-4 true leaves. A liquid for flowers with a concentration of 0,05% is used.

1-2 liters of medicine are used per 3 m4. For potted and ampelous flowers, the dose is increased to 0,07%.

For grapes

Potassium monophosphate is used for grapes when the weather was cool and humid. Fertilizer is used as a pre-winter preparation. This will allow the vine to overwinter well and produce a large harvest the next year.

The mixture can be sprayed both on the leaves of the grapes and applied under the root. It is used 1 time in 7 days until the beginning of October.

The consumption of potash fertilizer for the crop is 10-15 g per 8-10 liters of water.

For bushes and trees

For berry bushes and trees, the procedure is carried out after the flowers have fallen. The second time the mixture with potassium is used after 2-3 weeks. Additional feeding of trees for fruit ripening is carried out in mid-September.

Fertilizer consumption for trees and shrubs – 15 g per 10 liters of water.

Foliar top dressing

Foliar phosphorus top dressing is carried out by spraying. The procedure is carried out until film surface moistening. The appearance of rolling drops is unacceptable.

Fertilizer storage

Phosphorus top dressing is stored in a hermetically sealed bag. The room must be well ventilated.

Potash fertilizer has an unlimited shelf life. The main thing is to keep fertilizer away from water.

Is it possible to replace something with monopotassium phosphate

As an effective replacement in the garden, you can use wood ash. However, in this case, the amount of potassium may differ, for example, when burning straw, it is possible to obtain 30% of the element, and only 13% remains after branches from trees.

When applied correctly, fertilizer helps to improve the quality of the plant.
