RECOGNIZING THE LACK OF APPROPRIATE INGREDIENTS IN THE SOIL

Testing the amount of digestible nutrients in the soil is of great importance for its proper cultivation and preparation for sowing and planting plants.. It allows the use of appropriate organic and mineral fertilizers. Along with the harvest of vegetables, fruit and flowers are taken from the garden every year, a significant amount of nutrients needed for the proper growth of plants. However, using organic and mineral fertilizers at the same time, we enrich the soil with these ingredients again. For these reasons, the systematic control of the soil's nutrient content is a basic condition for rational fertilization of plants and allows to prevent the occurrence of both, and excess nutrients in the soil.

The appearance of plants is an indicator of the abundance of nutrients or their deficiency to some extent, as already mentioned. A more reliable way to determine the potassium content of a soil, phosphorus, magnesium and micronutrients available to plants and a method of determining the pH of the soil (as an indicator for liming purposes) is chemical soil analysis, performed by specialized laboratories. It allows you to define low, mean, high and very high content of nutrients during the vegetation period of plants in the garden. So that this analysis gives a real picture, the samples must be taken correctly. In this case, we usually limit ourselves to the arable layer, thickness approx 20 cm. When there is a need to explore deeper layers, e.g. in the orchard part of the plot or garden, then the topsoil and deeper samples should be taken separately. However, it must be noted, from what depth the samples were taken, e.g. 0-20 cm, 20-40 cm itd. The test soil should not be wet, but in such a state of humidity, in which it is suitable for cultivation.

From the backyard, with a homogeneous type of soil, topography, uniform type of the previously cultivated plant and organic and mineral fertilization, gets charged 5-10 single samples from random places, but evenly distributed over the entire surface of the garden. Such samples are taken, cutting even vertical slices of the arable layer with a spade, thickness 1 cm, to a depth of approx 20 cm. All collected samples are combined and thoroughly mixed, then sends it (in a polybag, weighing approx. 1 kg) to one of the chemical and agricultural stations, given below.

These stations are not only responsible for soil analysis, but also giving advice on fertilizing plants. Stations for the performance of the analysis charge fees according to the agreed price list.
