Question

Soil tilth refers to ________. Select one:
A. ratio of bulk density to particle density
B. the moisture content at which a soil is best suited for tillage
C. the physical suitability of a soil for plant growth
D. the bearing strength of a soil under a given downward force
E. micro-aggregates produced as a by-product of tillage

Answer 1

Answer:

Option c

Explanation:

Soil tilth refers to the physical condition of the soil, particularly with regards to the suitability of the soil for the growth of crop.

The determinants of the tilth in the soil incorporates the arrangement and steadiness of aggregated particles of the soil, pace of water penetration, level of air circulation, dampness content and seepage.

Thus option C follows the definition of the soil tilth.

Answer 2

Answer:

Option (C)

Explanation:

The soil tilth is defined as one of the physical property that determines the necessary condition for the better growth of plants and crops.

This property depends upon various factors such as-

• fertility of the soil

• amount of moisture content in the soil

• rate and type of drainage pattern

• rate of percolation of water into the deeper zone of the soil

• porosity and permeability of the soil.

These are the main features that characterize the soil tilth, and fulfilling the above required necessary condition, a plant grows in a much better way.

Thus, the correct answer is option (C).
