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.
Clay type, organic content, and soil structure also influence soil water retention. The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point.
