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.
Water retention curve is the relationship between the water content, Î¸, and the soil water potential, Ï. This curve is characteristic for different types of soil, and is also called the soil moisture characteristic. It is used to predict the soil water storage, water supply to the plants (field capacity) and soil aggregate stability.
