ST 30 Core Drilling Rigs Machine Application:
It is a kind of light and multi-purpose micro-engineering rig which is suitable for geological survey, geophysical prospecting, advanced drilling, grouting, embedding and so on in industrial and civil construction, bridges, railways, highways, hydropower and other industries. Pieces of holes, playing blasting holes, check holes, small household wells and so on.
Soil Sampling Method :
1. Distribution: samples shall be taken according to the soil type and the distribution of crop varieties, and according to the different soil fertility. The sampling points are distributed in zigzag or snake shape, which should be as uniform and random as possible.
2. Determine the sampling position and depth: the sampling position and depth shall be determined according to the thickness of the cultivated layer. Generally, the sampling depth is 0-20cm
Soil samples can be taken any time throughout the year. It is important though to sample approximately the same time of the year. Late summer, or early fall, is a good time for most crops. This allows time for lime recommended to react and change the pH before the crop is planted.
