Conventional tillage changes the porespace distribution of soil used for agricultural production compared to a similar soil under native vegetation. generally, following tillage, the volume of macropores is greater in the agricultural soil. this is a permanent change in macropore volume that remains long after tillage has ended. select one: a. true b. false.

The correct answer is False.

Explanation:

The soil has many beneficial characteristics, such as the ability to retain water that falls from rain or river overflows to avoid flooding and its good infiltration rates, good soil pores and density.

When farmers tillage on the soil, this quality drops dramatically, because the soil fractures and erodes.

The force with which the rain falls is stopped by crop residues, which are reduced when the soil is tilled.

With the lack of these residues the particles found in the soil move and are placed on the pores of the soil, obstructing them which implies a negative action in the process of water infiltration.

Therefore, all the good qualities of the soil are negatively affected by tillage.
