Question

Percolation rate is highest in which of the following soil
A. Humus
B. Clay Soil
C. Loamy soil
D. None of these

Answer 1

Hint: Percolation is the development of water through soil, and the percolation rate is the speed at which that development happens. Percolation tests, or perc tests, measure percolation rates. Soil research center experts ordinarily measure percolation rates as far as minutes per inch.

Step by step answer:
In humus, the percolation speed is high. This implies more measures of substances can go through it. Percolation rate is fundamentally the rate at which the water travels through granular material. In humus, water moves rapidly. Thus, its percolation rate is extremely high.
Loamy soil has moderate percolation speeds, running from 0.1 to 1 inch for each hour. This is the "Goldilocks" circumstance, in which soil holds water and supplements long enough for plant roots to assimilate them, yet the soil doesn't handily get waterlogged.
Clay soils have moderate percolation rates of 0.1 inch or less every hour. These soils effortlessly become waterlogged, and plant roots can choke thus.

Hence, option A is the right answer.

Note: A percolation test (casually called a perc test) is a test to decide the water retention pace of soil (that is, its ability for percolation) in anticipation of the structure of a septic channel field (drain field) or penetration bowl. The consequences of a percolation test are needed to appropriately plan a septic framework. In its broadest terms, percolation testing is seeing how rapidly a known volume of water disperses into the subsoil of a penetrated opening of known surface territory.
 While each region will have its laws concerning the specific computations for the length of a line, the profundity of the pit, the testing techniques are the equivalent.
