How to determine the soil?
Soils are different. By origin, they can be divided into sod-calcareous, sod-podzolic, gray forest, marsh (peaty), chernozem, floodplain and others. The mechanical composition is determined by the ratio of particles: clay (small) and sand (larger). There are sandy, clay, sandy and loamy. Sandy and sandy lands are called warm and light. They warm quickly and are easy to handle. Clay and loamy opposite - heavy and cold.
How to determine the soil: tips
Determine the mechanical composition of the soil as follows. Take a soil sample (1 teaspoon will be enough), wet it with water and try to make a ball out of it. If you fail, then this soil is sandy. If the ball you still turned out, try to roll it into a string. Did not roll? So the soil is sandy. If the string turned out, try to roll it into a ring. Does not exceed? The soil is light loam. Got a ring, but it is very broken or cracked - the soil is medium loamy.If only slightly loamy cracks. And at the end, we are dealing with clay soil, if the ringlet can easily be given any shape.
- Clay soil Very heavy and not breathing at all, but it is rich in various nutrients. If you wet it, it becomes plastic and is easy to model.
- Silty soil. Very fertile and perfectly retains moisture. It feels like soap. It breaks easily into pieces.
- Limestone soil. Small and stony, light shade, breathes well and moderately fertile.
- Sandy soil. Granular, its grains are not glued together. Dry, breathable, but infertile. Requires significant feeding and frequent watering.
- Peat soil. Excellent water retention, rich in organic matter. But it is often too acidic.
Soils are also divided into alkaline, neutral and acidic. Soil acidity is conventionally denoted by the pH sign with the corresponding figure.
- Strongly acidic, pH 3-4.
- Sour, pH 4-5.
- Subacid, pH 5.
- Neutral, pH 6-7.
- Alkaline, pH 7-8.
- Strongly alkaline, pH 8-9.
What is soil acidity
Acidic soil is characterized by a high concentration of hydrogen ions, which inhibits the natural processes of microbiology. And the soluble ammonium salts contained in it cause significant damage to plants. Determining the acidity of the soil - is a very important point for the farmer. After all, soil fertility and yield directly depend on acidity.
How to determine the acidity of the soil
There are many methods by which soil acidity can be determined. One of them is an indicator paper that you can easily buy in a gardening shop. On the site we dig a hole, the depth of which is 30-35 cm. From the vertical walls in 3-4 places we take 10-20 g of soil. Pour into a glass and pour 50 ml. rain or distilled water. Mix well. We take the indicator tape and drop it into the resulting solution. The color of the paper will change according to the composition of the soil. The result is compared with the scale on the cover. The color ranges from yellow to pink (pH5 - pH3) - the soil is acidic. From light green to blue (pH7-pH10) - alkaline.
Soil acidity can also be determined with an electric soil gauge, which will also determine the temperature, luminance and humidity of the plot.
To determine the acidity, you can try at home. Take a teaspoon of soil and pour it on the glass, which was previously placed on a dark surface.We take 9% vinegar and pour a small amount. Watching:
- Strong foaming - alkaline soil.
- Moderate - neutral.
- If there is no foam, the soil is acidic.
Now we know how easy it is to determine the acidity of the soil. We hope that this will help you grow a great harvest.
