Answer:
Topsoil is the primary resource for plants to grow and crops to thrive and the main two paramgeters for this are Carbon and Nitrogen.
2..loamy soil is considered the best soil used of gardening and for farming. hope it helps!!! The loamy soil is best suitable for growing crops because it is a mixture of sand, silt, clay and humus. It has the right amount of nutrients and water for plant growth.
3..forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up.
Explanation:
4..The relationship of soil drainage classes to percolation rates cannot be overlooked. It is obvious that many of the same factors which limit percolation rates such as pore space, texture, and structure also combine to cause natu- rally slow soil water movement, or perched and high water tables
5..These methods include planting vegetation to retain excess water, terrace slopes to reduce slope flow, and building alluviums (man-made channels to divert water from flooding), construction of dykes, dams, reservoirs or holding tanks to store extra water during flood periods.
