How to take a soil sample
most accurate results can be obtained by comprehensive analysis, conduct which offer specialized laboratories.Why only need to prepare the material, ie soil from your land, for the analysis, but this must be done properly, because of this depends largely on the degree of accuracy of the results.
soil samples from the area should be taken to the application of fertilizers and of the liming.In different places of land need to pit to a depth of bayonet spade, or a little deeper.It is this depth of most plants need to free accommodation and food of the root system, therefore, the soil should be thoroughly investigated in this area.In total at least be 15-20 dig holes, thereby achieving more objective test, and thus, a 100 m2 area plot should be taken at least 15-20 samples.Then, sequentially from the wall of each of the holes you need a shovel to scrape off a thin layer of earth from the bottom up and put in a bucket, then all samples are thoroughly mixed in a bucket.Not less than 1 kg of the soil mix to pu
se wall of each well layer of earth from the bottom up, mix all samples and not less than 1 kg of soil sent for analysis
ethylene bag and tightly close it.Presenting the soil to a laboratory for analysis, enter your site characteristics, location and the main purpose for which you intend to use the land (cultivation of vegetables, fruit, or anything else).you can on the basis of the resulting analysis to determine exactly in which nutrients and trace elements particularly need soil, which is necessary to make fertilizer and some measures to improve the composition of the soil should be taken.
important in soil quality assessment plays its appearance, by which you can determine accurately the structure, some of the internal properties and the quality of the soil.One of the most important external soil features is its color. If you dig a hole depth of at least 1 meter, you will get the soil profile, that is, the soil structure in the section.On the side wall of the well can be traced sequentially alternating layers of soil and their color change in the direction of the pit bottom.Soil color is directly related to its characteristics such as the level of fertility.This is quite logical conclusion, since the appearance of the soil and its fertility are determined by numerous factors which influence its formation. dark soil, usually characterized by a high level of fertility, as are the best conditions for growing plants and waste soil microorganisms than light soil. dark soil color due to the high content of organic matter of the soil humus.It is a good quality humus contained in the soil in sufficient quantities, determines the soil saturated dark color.However, not only humus provides a particular color of the soil, but also numerous chemical compounds, such as iron oxides, giving the soil brown, reddish, rusty reddish and yellowish shades.In the soil profile at different depths can appear plates of bluish-gray or blue-gray color, which is a bad characteristic portion of the soil, as evidenced by the presence of permanent waterlogged soil strata as a result of which there are ferrous iron compound.Such soils will require more effort for improving, but a lot also depends on the depth of the blue clay layers.
Also special analysis of a number of methods of self-analysis of the soil.Of course, such methods do not produce an accurate assessment of all chemical characteristics of the soil at a particular location, but will give an idea of its basic parameters and allow the right decision for further processing and fertilizers.This will help the home mini-laboratory, which is a set of reagents and indicators fitted with a color scale for comparative analysis of the acid-base reaction of the soil with the help of indicator paper and detailed description of all possible tests of the soil.In addition, the soil can be investigated visually. This will give you at least fairly clear idea of the structure and composition of the soil.If you make a hole depth of one to two bayonet shovels and consider cutting profile, color successive layers can be roughly determine which soil you are dealing.Most often, the top layer of darker follow-up, indicating that a higher content of organic matter in it or humus.Its thickness can vary, but preferably it is not less than 10 to 15 cm, that is, the depth where the plant rooting.Peat soils are almost black due to the high content of organic mass.Sandy ground layer is yellowish-gray, loamy layer - light-brown with different shades, a clay layer can be of different colors - from brown and red to whitish.
Soil Investigation Manual
If you are not quite sure what the composition of the soil in your yard, it can be checked as follows: Take a handful of moist, but not wet soil and rub it between your fingers.
If granular soil structure if it does not stick together and rolled into balls before you sandy loam or sandy soil.
ft If the soil is granular, but rolled into a ball, or a ball, it is a sandy loam .
If the soil has a granular structure or sticky and out of the can between your hands to roll the sausage, then you are dealing with bold sandy loam.
If the resulting sausage flexible, you can bend the ring and it is not fault it clay. Knowing the structural properties of your soil, you will be able to determine what measures should be taken to improve it.
When soil study manually easy to see that the individual particles of soil are quite different from each other.In sandy soils or soils with a high content of sand particulates large and rough, a distinct sense of touch.The more soil sticks together, the smaller, finer particles it, which indicates a high content of clay in the soil.Good soil is of mixed composition of the gross and subtle
particles, which are formed into small lumps loose.The soil is rich in humus has a pleasant smell of a healthy forest land, rotting leaves and grass.
time for sampling soil
From time also depends on the accuracy of the analysis.Soil samples should be taken in the early spring or late fall, that is, before or after the period of the growing season.If the sample is taken in the spring it should be done before the application of fertilizers if the fall, then not later than 2 months after the last fertilization and prior to their introduction in the autumn digging.
