In the process of growing garden, horticultural and agricultural crops, the soil is greatly depleted, and this, of course, has an extremely negative effect on productivity. Fertilizers should be used to replenish nutrients in the ground.
Varieties of dressings
All fertilizers used in agriculture and household plots can be divided into four large groups:
- organic;
- mineral;
- bacterial mixtures;
- organomineral.
The last type of top dressing is considered the most effective and economical.
What is organic fertilizer
Such dressings, as the name suggests, are a complex mixture consisting of two types of components. Humus or manure (chicken, horse, cow) is usually used as their organic component. All these elements are able not only to fill the deficiency of nutrients in the soil, but also to improve its structure. However, unfortunately, such dressings contain far from the entire complex of macro- and microelements. Therefore, they are supplemented with various mineral components. It can be potassium, nitrogen, phosphorus, magnesium, etc.
All these substances are absorbed by plants very well and in a short time, and therefore, they have a quick effect in terms of gaining green mass by crops, the development of ovaries and fruits. The type of macro-, microelements necessary for plants depends on their age, the type of soil on the site, etc.
Thus, organomineral fertilizers simultaneously improve the structure of the soil and saturate it with all the necessary crops, moreover, with quickly digestible nutrients.
Varieties of organomineral compositions
There are several types of such fertilizers:
- granular;
- liquid;
- complex mixtures;
- humic mixtures.
Liquid organomineral fertilizers are used to feed cultivated plants by the foliar method, that is, they spray the green mass abundantly. This method allows you to get an almost instant effect. All other varieties of organomineral dressings are mostly embedded in the soil.
Application Features
You can use all types of organomineral fertilizers for any cultivated plants. Moreover, they can be used on almost all types of soils. It is possible to fertilize the land with the compositions of this group both in spring, before planting crops, and in autumn, for digging. Of course, it is useful to use them throughout the growing season.
Before applying this or that organomineral top dressing to the beds, it is imperative to determine the composition of the soil. To do this, you can use, for example, a special kit bought in a store. After all, such fertilizers may contain different mineral components.
Pros and cons
The advantages of this type of feeding in comparison with the usual have a lot. Such fertilizers are assimilated quickly and at the same time improve soil structure. They also have the advantage of being long lasting. Such dressings are very easy to dose, besides, they are completely safe both for the environment and for the plants themselves or the human body.
Summer residents and farmers who have ever used such products have noticed that after their use, crops become much more productive and productive. In agriculture, this type of fertilizer helps prevent soil degradation. Humic top dressings of this group, among other things, also reduce the percentage of nitrates in the fruits of plants.
Refer to the benefits of this group of fertilizers and profitability. In order to improve soil quality, they require 10 times less than organic, and 2-3 times less than mineral.
There are practically no drawbacks to such complex dressings. The only thing is that humic mixtures are mainly used only infarms. The fact is that due to the rather high cost, it is usually simply unprofitable to use such products for a small number of plants.
How they do it
The production of organomineral fertilizers is a relatively simple procedure, but it requires precise adherence to technological processes. The method of making such dressings depends, of course, primarily on their variety.
Thus, in the production of liquid forms, ordinary water is used as a solvent. In most cases, such dressings are concentrates. Therefore, before use, they are additionally diluted with water in certain proportions.
Granular fertilizers of this group are made with preliminary drying of organic components. After removing moisture from them, mineral components are mixed with them. It can be, for example, chalk or s alt. The mixture thus obtained is loaded into a granule making machine. At the final stage, the finished fertilizer is sifted and packaged in bags.
Humic dressings are made in much the same way. But the source material in this case goes through several degrees of purification. Instead of granules, the output of such dressings is either a powder or a concentrated liquid.
Features of use
The amount and timing of the application of organomineral fertilizers depend on many factors. On light soils, the required dose of such dressings is 80-100 g/m2, onheavy - 50-70 g/m2. In the spring, when planting potatoes or seedlings of vegetable crops, 20-30 g of the product is poured into the wells. For fruit and berry crops, this rate is 50-70 g.
Efficiency in use
The use of organomineral complex fertilizers, as already mentioned, can significantly improve the quality of land in suburban areas and farm fields. Studies conducted by scientists have shown that after using this type of top dressing, the content in the soil increases:
- organic substances - 2.5 times;
- phosphorus and potassium - almost 2 times;
- magnesium and calcium - 1.5 times.
Actually, the crop yield itself increases by an average of 30%.
Universal Fertilizers
There are many types of such dressings in terms of composition. So, for example, specialized fertilizer for strawberries organo-mineral "Ogorodnik" is very popular among summer residents. This top dressing is made on the basis of the latest technologies and contains a full range of macro- and microelements necessary for this crop in an organic shell.
But the most popular variety of such fertilizer is, of course, universal. Most often, gardeners use the compositions "Fortress" and "Barrel and four buckets" to feed plants. These tools allow you to significantly increase the yield on the site and at the same time are inexpensive.
Universal organo-mineral fertilizer "Barrel and four buckets" is appreciated by gardeners and gardenersprimarily for low cost. This is one of the few humic top dressings that are excellent for use in home gardens. It is usually sold either in tablets or in liquid form.
A particularly convenient form of packaging of this fertilizer is considered dry by gardeners. Universal organomineral fertilizer "Barrel and four buckets" is sold in one tablet, which should be dissolved in 50 liters of water, that is, in five standard buckets. For many summer residents, one tablet of "Barrels" is enough for the whole garden.
Universal fertilizer "Fortress" can also be produced in different forms. It is used not only for adult plants, but also for seedlings. In any case, its consumption is on average 2 tsp. for 10 liters of water.
Organomineral fertilizers: reviews of summer residents
Of course, the opinion of gardeners about this type of top dressing is very good. Owners of suburban areas believe that such fertilizers are effective, and it is convenient to use them. In addition, in order to increase the yield of garden and horticultural crops, they need to be applied very little.
In general, they deserve really good organomineral fertilizer reviews. Their prices are actually very low. So, "Barrel and four buckets" costs about 80 rubles. for a half-liter bottle and 35 rubles. for a pill. For 50 g of Krepysh you will have to pay about 40 rubles, and for 1 kg of Ogorodnik top dressing for strawberries - 55-60 rubles.
