Complex fertilizers for feeding the garden and vegetable garden
Fertilizers are considered complex, consisting of several substances necessary for the normal growth of crops, and trace elements. Depending on the production technology, they are complex, complex-mixed and mixed. These substances are used to fertilize the garden and vegetable garden at different periods. The most popular complex fertilizers are nitroammofoska, potassium nitrate, ammophos and nitrophoska.
Nitroammofoska
This substance is considered one of the best fertilizers containing the main nutrients: nitrogen, phosphorus, potassium and a little sulfur. It is a pinkish-grayish granules. It has several brands with different contents of the most important elements.
It is very often used to fertilize the garden and vegetable garden. This is due to the fact that the action of nitroammofoska is manifested to the same extent in any soil. Nitrogen, phosphorus and potassium from it are perfectly absorbed by various plants. Moreover, this substance belongs to neutral complex fertilizers. It has a good effect on the growth of crops, increases their resistance to diseases, prevents the accumulation of nitrates, thereby increasing the quality of the crop.
Nitroammofosk does not absorb moisture, does not cake, and dissolves well in water. It can be stored for up to six months. It does not have a toxic effect, being considered an environmentally friendly substance. The granular form allows you to evenly distribute the fertilizer during application.

Application of nitroammophoska
This complex can be used for both main application and top dressing. It is suitable for open and sheltered soils. On heavy types of soils, nitroammofosk is often applied in the fall. Light types of soils respond better to the spring application of this substance, since with autumn fertilization during the winter, nitrogen loss is possible.
Consumption rates:
- to fertilize the garden in the spring, 15-20 grams of nitroammofoska are applied per square meter of soil;
- for application under fruit trees, 400-500 grams of granules are used;
- for feeding shrubs, 30-40 grams of nitroammofoska are used.
How to improve yields?We are constantly receiving letters in which amateur gardeners are worried that due to the cold summer this year there is a poor harvest of potatoes, tomatoes, cucumbers, and other vegetables. Last year we published TIPS on this matter. But unfortunately, many did not listen, but some still applied. Here is a report from our reader, we want to advise plant growth biostimulants that will help increase the yield up to 50-70%.

Also, this drug is suitable for foliar feeding. It is often used as a solution. When applying dry granules, you must first water the soil abundantly. To prepare the solution, add 2 tablespoons of nitroammophoska to 10 liters of water.
Potassium nitrate
Potassium nitrate or potassium nitrate is a complex fertilizer suitable for application to different types of soils. Plants that do not tolerate chlorine react especially well to it. These include flax, potatoes and grapes.
Potassium nitrate contains 13% nitrogen and 46% potassium as oxides. Belongs to water-soluble fertilizers. It is used for feeding vegetables, fruit trees and shrubs, flowers and ornamental plants. This substance enhances the absorbency of the roots, improves plant respiration and accelerates photosynthesis in the leaves. Thanks to this action, the resistance of crops to various diseases and pests is increased. In addition, potassium nitrate has a positive effect on the size of root crops and their taste.
Potassium nitrate is perfect for adding under potatoes and cabbage. Top dressing is done during the active growth of vegetables. Potassium nitrate protects plants from an excess of nitrogen, since the nitrogen content in it is several times less than that of potassium. Also used for application under vegetable crops growing in greenhouses.
Potassium nitrate application rates
This substance is used for root and foliar feeding. Root feeding:
- for application under vegetables and flowers, dissolve 100-150 grams of potassium nitrate in 10 liters of water;
- for ornamental and berry bushes, a solution is made consisting of 10 liters of water and 100-200 grams of potassium nitrate;
- for watering fruit trees, 250 grams of dry matter are bred in 10 liters of water.
Such feeding is carried out every two weeks.
Foliar feeding involves the use of a 1.5-2% solution. They are sprayed with leaves.
Estimated consumption:
- vegetables, flowers - 1.0-1.5 liters per 10 meters of square plantings;
- bushes - 1.5 liters for each of them;
- fruit trees - 2-8 liters per tree, depending on its size.
Ammophos
It is one of the most effective phosphorus-potassium fertilizers, and the amount of phosphorus in its composition is 4 times higher than the content of potassium. Often used to fertilize the garden. Contains 10-12% potassium and 52% phosphorus. The product has good water solubility.
Well absorbed by plants. In appearance, these are granules that practically do not absorb moisture, so they can be stored for a long time.
Ammophos is used to saturate crops with phosphorus at the beginning of their development, since it affects the root system to a greater extent. It is at this time that the roots of plants are still weak and poorly assimilate nutrients. The introduction of phosphorus stimulates the development of a full-fledged root system, accelerates the formation of shoots on grape bushes, and increases the resistance of crops to drought and diseases.
With a lack of phosphorus, the development of crops slows down, yields decrease and taste deteriorates. Ammophos is suitable for autumn and spring application under crops, fruit trees and shrubs. Before sowing grain crops, ammophos is fertilized into the soil at the rate of 60-90 kilograms of dry matter per hectare of area. When fertilizing the garden, 200-350 grams of granules are applied under each tree.
Nitrophoska
The drug contains 11% nitrogen, 10% phosphorus and 11% potassium. Produced in granular form. Nitrophoska is used both dry and liquid. Best suited for acidic or neutral soils, but can also be applied to alkaline soils if needed. Nitrophoska is most effective on sandy, clay and peat-bog soil. They are introduced before planting crops, in the fall after harvesting and as a supplementary feed during the entire growing season.
Nitrophoska is used for application under any vegetables, fruit trees, shrubs and herbs.
Application rates:
- before sowing seeds of vegetables and flowers - 5-7 grams per square meter of the plot;
- for potatoes and before planting seedlings - 4-6 grams per hole;
- for fruiting bushes - 50-70 grams for each shrub;
- for fruit trees - 200-250 grams for each young tree and 450-600 grams for an adult.
