Depending on our needs, but rather on the needs of the plants that want to grow, you can affect the quality of the soil in the garden, using the optimum amount of fertilizer.One common error is a fertilizer "by eye", which can lead to unnecessary consequences.To reduce the risk of error should establish the form and characteristics of the soil in which the plants will be grown, that is, to make a sample of the soil.
To obtain accurate results, it is best to take a sample of the land and give it to a study in a special laboratory.Unfortunately, such an analysis would have to pay, so many decide on their own to determine the characteristics of the soil.Here are some tips how you can own way to perform a simple test.
first element that can be set is the type of soil.This may be the soil is light, medium or heavy.In order to determine the texture of the soil, take a soil sample (no more than 1 teaspoon), moisten with water and turn it into a ball.If the ball does not work, it means that the
also possible to determine the type of soil, rubbed between the fingers of a handful of earth.In determining the characteristics of the soil will help the table and pictures below.
|Soil type Features||soil||horticulturally|
|soil is heavy clay||After grinding heavily stain fingers wet molding can be easily (you can sculpt from her various forms)||rich nutrients and moisture.Unfortunately, a very dense, poorly breathable and hard in cultivation.Use a soil in pure form is not recommended.|
|average soil, sand and clay.||After grinding the feeling of having sand lightly soiled fingers, wet from it can be made thick rollers are easy to break.||Well absorbs and retains water, and a moderately loose "breathable", well heated.It is the most fertile.|
|soil is light and sandy.||easy break, not plastic, does not contaminate the fingers, even when wet can not be modeling.||main advantage is a good throughput of air.Water it is not delayed, resulting in rapid drying.Nutrients easily leached.This stage can be corrected by adding organic fertilizers.|
| Clay soil is rich in nutrients but is very heavy and "not breathing" when wet - plastic and amenable to modeling. |
|silty soils is fertile and retains water well enough, but, unfortunately, easily falling apart, and feels like soap.|
|peat soils rich in organic matter and retains moisture well, it is often too acidic, requires the addition of limestone.|
|limestone soil is light in color, is small and rocky, well "breathes" and moderately fertile.|
|Sandy soil is granular to the touch, its particles do not stick together, the hands do not get dirty.It is dry, "breathing", little fertile, requires frequent watering and fertilizing.|
Another feature of the soil, which must be set before using the fertilizer is its acidity.PH of the soil shows its acidity or alkalinity.Neutral pH 7. If the above 7, it means that the soil is alkaline, and if less than 7, it means that the soil is acidic.The acidity level of the soil affects the solubility of minerals and their access to the plants, as well as the variety and size of the population of organisms living in the soil.Most garden plants need soil with a pH of 6,2-6,8.However, there is a fairly large group of plants that need more acidic soil.
To manually set the pH of the soil, need a special kit for such research, which consists of a test cone filled with a solution that changes color after mixing with the soil.The flask replenish the earth, the amounts indicated in the instructions (for example, & amp; 襴), then shaken vigorously to mix the solution.Then, you need to wait until the earth has settled on the bottom of the flask, and the solution will be painted in the appropriate color.Upon receipt of the color of the solution is determined in the instruction acidity.
Warning: the pH of the indicator is not constant, so the study should take some soil samples from different parts of the garden.Furthermore, such studies should be carried out regularly, especially after an artificial change in the composition.
If it appears that the soil is too acidic, it can enrich the lime or limestone containing organic matter (eg, mushroom land).If the soil is highly alkaline, the pH can be reduced by adding more acid or a mixture of soil and peat, or also use the manure containing sulfur.
Plants that help to determine the type of soil
In determining the characteristics of the soil can also help the study of plants growing on the site.Daisies, daisies odorless and white clover grow on poor soils and crop failures.The emergence of these plants shows that definitely need to regularly feeding complex fertilizers.
If the site there is a large number of lice, nettle, wild mustard, galinsoga melkotsvetnoy or minuartia, it indicates that the soil has a lot of nitrogen.When the fertilizer should be used only if the manure, which lacks this element.
appearance of the horsetail, mother and stepmother, or creeping buttercup says that the soil is wet and heavy.In this case, it is recommended to loosen the soil and mix it with sand.
