Soil sample analysis

Defined parameters:
pH, EC, salinity, NO3-N, P2O5, K2O, Ca, Mg, Fe, Cu, B, SO4-S, Cl, HCO3, Na volume weight, binding and water content, and also from AL extracts: P2O5, K2O

Sampling rule: Sampling should aim at taking an average sample representative of the area. An average sample may cover a maximum area of 5 ha. If the area of a plot exceeds 5 ha, the plot must be subdivided into 5 ha, preferably homogeneous areas. The average sample shall be taken from a soil uniform area using the same method, from the same level and using the same method. - For arable crops, the average sample shall be taken from the cultivated layer (0-30 cm) per plot up to a maximum of 5 ha. - In the case of pasture-grassland crops, an average sample shall be taken from a depth of 2-20 cm per plot, but not more than every 5 ha. - For standing crops 0-30, 30-60 cm, for berry crops 0-20, 20-40 cm soil samples shall be taken from 1 soil sample per plot. The average sample consists of subsamples. The more sub-samples you take, the more accurate the results will be. From the area to be sampled, the subsamples should be taken in a zigzag line or along a diagonal to best represent the area.It is FORBIDDEN to take samples - at the edge of the field in a 20m strip - in the rotation - at the strawbale - at the fertiliser, soil improver, organic manure depots - at the animal dolphin site When sampling, collect each sub-sample in a bucket and mix thoroughly after sampling the plot. Of the homogeneous average sample obtained, representing the whole field, fill 1-1,5 kg into a polyethylene bag of a size to contain 1-2 kg of soil, which can be tied with its own material. Before tying the bag, the samples should be labelled with a sample identification tag containing the name of the farmer, the nature of the test, the place and time of sampling, the plot number, the sample code and the depth of sampling. The sample identification ticket thus filled in should be placed in a separate bag (to ensure legibility of the data) and placed in the bag containing the soil.
