Name: Soil hardness meter ；Model: TRY-1
Detailed product Description:
► The soil hardness tester is the use of pressure gauge of the theoretical value Kg/Cm2,
direct measurement of soil hardness value
Specification
The steps of how to measurement:
1. First measure the soil surface level, and then let cutting-edge part of the device inserted into the soil all until the mouth
2. Perpendicular to the pull out the sclerometer and read the hardness value from the table
3. After reading the measured value, please follower needle rotary knob so that indicator zero
4. If the internal attach soil, will make the measured value incorrect, anti-clockwise rotation mouth of the sleeve off this round, please clean up, then fixed it original position to be measured again.Hardness indicate range: 0 ~ 40 mm, 0 ~ 500 Kg/Cm2

Action
|
Soil compaction is a serious and expensive problem. Severely compacted soil is difficult to work and can lead to poor root and plant development. Compaction restricts efficient water management by limiting the ability of plants to take up water and nutrients from the soil. A compacted zone can also make fertilizers and pesticides difficult to utilize. If not absorbed, they can easily wash away. If trapped near the surface, they can concentrate and damage crops.
Soil Compaction Meter is used in testing the hard of soil, too solid soil may prevent the moisture content permeating, reduces the factor of the chemical fertilizer use. Influence plant root system's growth. That will cause the crops’ production reduced.
