Contents: Soil chemistry of checkdam and control samples
Description: This table contains some of the results of the soil fertility study. Areas tested include samples collected from checkdam features and control samples from areas lacking visible agricultural features. This table includes the results of both chemical tests (P, CA, K, MG) and tests of properties that affect availability of nutrients, plant growth and physcial soil characteristics such as pH, organic matter content (OM), calcium carbonate content (CaCO3), soluble salt content and cation exchange capacity (CEC). See checksoilstat for statistical testing of results.
