Soils high in organic matter commonly hold more available water than comparable soils with lower organic matter levels.This is most likely due to what characteristics of the high O.M.soils
A)larger micro pore space
B)lower permanent wilting percentage
C)higher field capacity
D)higher capacity of the O.M.to hold water tightly
E)higher clay content

Question

Quizplus · Accepted Answer

Organic matter can improve soil structure, leading to better soil aggregation and pore space, which in turn allows for better water infiltration and retention. This results in a higher field capacity, or the amount of water the soil can hold against gravity after being saturated and allowing excess water to drain away. While organic matter can also hold water tightly, leading to higher water-holding capacity, this does not necessarily result in more available water for plants. Similarly, clay content may also contribute to higher water-holding capacity but is not the primary reason for the increased available water in soils high in organic matter. A lower permanent wilting percentage, or the amount of soil water that is unavailable to plants, may also result from higher organic matter levels, but it is not the main reason for increased available water.
