PRESSURE PLATE APPARATUS
MAKE DINESH SCIENTIFIC MODEL DS-PPA-15
DESCRIPTION
Pressure plate apparatus is used to establish moisture retention for any soil type. It is a reliable means of removing soil moisture, under controlled conditions from the soil samples throughout the plant growth range, without disturbing the soil structure. By contrast the Pressure Plate apparatus provide a convenient, reliable means of removing soil moisture, under controlled conditions, from soil samples throughout the whole plant growth range, without disturbing the soil structure. The method may be used on disturbed samples or undisturbed soil cores. Used to obtain soil moisture characteristics curve and soil water retention parameter and suctions Bar.
FEATURES:
- Approved quality
- Excellent finish
- Attractive design
SCOPE OF APPLICATION:
The apparatus consists of strongly built metal chambers containing one or more ceramic plates onto which uniform soil samples are placed. Having attained maximum moisture retention (field capacity) the samples within the cells are then subjected to controlled positive air pressures and water is gradually removed. By careful control of pressure, the various equilibrium conditions of pressure and soil water tension or suction, are obtained. The air pressure is provided either from a compressor, compressed air bottle, or nitrogen bottle; but must always be routed through a manifold having pressure regulators and gauges. This versatile apparatus can be used for a variety of determinations, available water capacity, water retentivity, hydraulic conductivity, and field capacity. Results have a variety of practical applications; soil classification and soil survey, the optimisation of irrigation and drainagein improving crop yields, and the calibration of soil water measuring apparatus for field use
