The water logging capacity of garden soil will be determined by measuring the weight of
- Asoil by adding water and humus
- Correct answerBwater saturated soil then heating the soil till it is dry and then measuring the weight of soil
- Csoil by adding water, biomass and humus
- Dsoil from different locations with biomass.
Solution
The optimum or maximum amount of water retained per unit dry weight of soil after the stoppage of gravitational flow is called field capacity. Soil moisture beyond field capacity produces water logging. The soil with high water retention and low or negligible percolation rate is prone to water logging.
Hence, the correct answer is option: 'B'.
