    Pan evaporimeter measure combined effects of several climate elements: temperature, humidity, rainfall, drought dispersion, solar radiation, and wind.

    This gives an idea as to how much water could be lost from the plant by way of evapotranspiration.

    This is very helpful for irrigation. It helps to know just the right amount of water to supply to the crops.


    A hydrometer can be used to grade fine-grained soils, silts and clay. Hydrometer analysis is performed if the grain sizes are too small for sieve analysis.

    This also gives an idea about soil texture and so the rate of water infiltration into the type of soil.

    Soil hydrometer can also give you an idea on the total nitrogen and total phosphorus in the soil. This is very help to apply the right soil enhancements.
