Answer:
The answer is: letter C, It increases water holding capacity of the soil.
Explanation:
"Soil tilth"<em> refers to the soil condition in reference to how sustainable it is for plant growth.</em> There are several factors affecting the tilth (cultivation) of the soil. These are <em>moisture content, infiltration rate, porosity of the soil and so on. </em>
A good soil is necessary for good plant growth because it increases water holding capacity of the soil. This, particularly, refers to the water from the earth's ground which enters the soil. This process is called "water infiltration."
<u>An increase in water infiltration means that there's a reduction in </u><u>"runoff."</u><u> </u>This then increases the ability of the roots to extract both nutrients and water from the soil. Thus, the plant can grow properly.
