1. Appropriate timing. To collect soil samples can be done throughout the year but the best time is after you harvest crops or the late planting
2. Should not collect samples of soil, while still very wet land or water are trapped because they are more difficult to mash the soil surface. Proper humidity to collect soil samples. May be noted: The soil does not stick to hands would shake up the rolls and when test will loose soil.
. 3. Do not keep the soil samples. Where is the old House. Bent out of shape old animals, or where there is a residual fertilizer
4. The tools used to collect soil samples, i.e. every cylinder bore drill, shovel shovel up. Tools used for digging Earth and clay containers must be clean, without soil. Fertilizers and other chemicals.
5. Divide the area into small changes which are not fixed as the principle, the amount is determined depending on the type of area, nature, plants and history of fertilizer and cement. If the soil has a characteristic smooth. Have a tilt at least it might keep the soil sample 1 per 10
20 – farm area.
