Macbeth is concerned about the blood on his hands because he couldn't believe that he had really killed King Duncan. He says that no amount of water could wash away the bloo â¦ d, because washing the blood away couldn't bring the King back.
5. What characteristic of soil is most important in determining water holding capacity? I think the soils actual composition is most important when determining water holding capacity. If you look at clay compared to sand, you would know that the tiny clay particles are very tightly packed together which allows very little water to pass through.
The volumetric soil moisture content at the wilting point will have dropped to around 5 to 10% for sandy soils, 10 to 15% in loam soils, and 15 to 20% in clay soils. The total available water (holding) capacity is the portion of water that can be absorbed by plant roots.
