The water logging capacity of garden soil will be determined by measuring the weight of

Options

  1. Asoil by adding water and humus
  2. Bwater saturated soil then heating the soil till it is dry and then measuring the weight of soil
  3. Csoil by adding water, biomass and humus
  4. Dsoil from different locations with biomass.

Correct answer

B. water saturated soil then heating the soil till it is dry and then measuring the weight of soil

Step-by-step 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.
