DETERMINE THE WATER HOLDING CAPACITY
DETERMINE THE WATER HOLDING CAPACITY OF SOIL MOISTURE CONTENT AND PH OF DIFFERENT SOIL SAMPLES
BIOLOGY | CLASS 12 | LABORATORY | MOISTURE CONTENT OF SOIL | BIOLOGY PRACTICAL CLASS 12 | PH OF DIFFERENT SOIL SAMPLES | WATER HOLDING CAPACITY OF SOIL |
Compare % water holding capacity of soil collected from different habitat
conditions. The variation in water holding capacity is due to varying
proportion of sand, silt and clay in the soil of different habitats. Soil with
very high proportion of sand have very low water holding capacity due to
large pore spaces between the particles which enables the water to percolate
freely into deeper layers leaving upper layers practically dry. In clay soil,
due to very small size of the pore spaces (fine capillaries) the water is retained
in the capillary spaces as capillary water. In these soil the water does not
percolate freely. Soil with more or less equal proportion of sand, silt and clay
(loam soil) combines the properties of sand and clay and therefore has
optimum water holding capacity and optimum soil-air for root growth.

Questions
1. What are heavy soil and light soil?
2. Give examples of a plant seen in heavy soil and light soil.
3. How does pore space determine the % water holding capacity of soil?
4. Why is clay soil often referred to as physiologically dry soil?
5. Which type of soil is suitable for cultivation of crop plants?
6. How can water-holding capacity of soil be improved?
7. Dead decomposed organic matter is usually added in the fields before the
cultivation of crops. Apart from providing the mineral nutrients, what additional
role does organic matter play in the cultivation of crop plants?
