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.
Soil is essential for plant growth for several reasons. Soil provides plant roots with nutrients, water and air. Soil also serves to anchor the plant. There are different types of soil, and it is very common to find the foundation soil around your house to differ from your property line soil. Soil is comprised of three mineral particle sizes: sand, silt and clay. Large, course mineral particles are sand, fine mineral particles are silt, and very fine mineral particles are clay. An ideal soil is composed of 45 percent mineral (sand, silt and clay), five percent organic material (humus or plant debris and soil organisms), 25 percent water and 25 percent air.
