in topsoil they can absorb the amount of water and the nutricient they need plus the soil must not be completely wet because the roots rot and they also need air in the roots. in subsoil there is more water and causes diseases to the roots and there is not enough air.so topsoil has less humus

∙ 13y agoTopsoil has more nutrients than subsoil.
Subsoil normally lacks the biological activity (and warm temperatures) of topsoil, with less biological and insect activity there is less organic matter in this section of the soil.
Less organic matter means less nutrients.

∙ 9y agoTop soil is the top few inches of soil. It has the most humus and nutrients. It also has microorganisms that can help plants grow. If your top soil is not good, you need to amend your soil to be successful at gardening. Most plants require good soil. Things like manure, compost, lime and fertilizer can amend the soil but get a soil test so you know what if anything needs to be added.
