Soil moisture is the amount of water contained in the soil after precipitation seeps into the ground. 1.The degree to which water clings to the soil is the most important soil water characteristic to a growing plant. This concept is often expressed as soil moisture tensi â¦ on.
Ideal soil conditions are around 15% to 20% moisture. Within this range a fine-textured soil, such as a silty clay loam, feels slightly moist. Pressed in the palm of your hand, it will form a weak ball with rough surfaces that crumbles under pressure and does not leave water stains on the hand.
