This summary should include the effects of increasing the percentage of soil on various ‘grades’ of sand. Compare the drop-off of percolation and aeration porosity as soil increases in the different mixes, and compare the effect of the two peats using the one sand. Next, discuss what this means to you as you try to advise persons on what kind of mix and what kind of components to select when building a golf green or athletic field. Often for bidding and budgeting purposes, some ball park idea of the quantities of material required has to be determined long before any mix can be tested. How do the results of this exercise inform your decision making process?
