The volume composition of soil which gives optimum condition for crop growth is
An ideal soil supports proper root growth and microbial activity.
Mineral matter forms the major portion of soil volume.
Organic matter improves structure and nutrient supply.
Equal proportion of air and water ensures aeration and moisture.
The standard ideal composition is 45% mineral, 5% organic, 25% water, 25% air.
Thus option (a) is correct.
