Working with a group of people to build a pump track in Alamosa county. Was wondering what are the best dirt compositions for Colorado? Have done some research that says high clay content in screened loam, but what composition would that be? 60/40 clay/loam? more or less? Also have seen recommendations for pitchers mound dirt, which is 40% clay, 40% sand, and 20% silt. Currently have screened loam, and just need to specify how much clay should be added.
