GK 200 Engineering Drilling Rig Advantages
1) It has a hydraulic feeding structure to improve the drilling efficiency and reduce the labor intensity of workers.
(2) The drilling rig is equipped with upper ball clamp clamping mechanism and hexagonal active drill pipe, which can reverse the rod without shutdown and is easy to operate.
(3) It is equipped with a hole bottom pressure gauge to indicate the pressure, which is convenient to master the situation in the hole.
(4) The handle is centralized and easy to operate.
(5) The base is equipped with an oil cylinder, which can move back and forth for easy lifting and lowering of drilling tools
(6) The drilling rig has the advantages of compact structure, small volume, light weight, strong decomposition and easy relocation. The loading form is trailer type, crawler type and disassembly. It is suitable for working in plain or mountainous areas.
What is the best time to do soil sampling?
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
The specific steps of soil sampling method are as follows:
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 Sampling Procedure
Divide the field into different homogeneous units based on the visual observation and farmer’s experience.
Remove the surface litter at the sampling spot.
Drive the auger to a plough depth of 15 cm and draw the soil sample.
Collect at least 10 to 15 samples from each sampling unit and place in a bucket or tray.
If auger is not available, make a ‘V’ shaped cut to a depth of 15 cm in the sampling spot using spade.
Remove thick slices of soil from top to bottom of exposed face of the ‘V’ shaped cut and place in a clean container.
