High-carbon char was applied in spring 2016 and rototilled into the top 6 inches of soil at both sites ( Figure 3 ). Soil was sampled at the 0-4 inch depth in spring 2017. The impact of high-carbon char on crop yield and soil physical and chemical properties including soil compaction properties (soil bulk density, penetration resistance, and shear strength), soil water content, cation exchange capacity, total carbon, and macro- and micronutrients was studied.
Does carbon char affect crop yield?
There was no significant increase in crop yield with high-carbon char application for the first year. In addition, high-carbon char had minimal influence on soil physical and chemical properties. Bulk density and shear strength were unaffected by high-carbon char application at the Sidney and Scottsbluff sites. However, the degraded site in Sidney showed a trend of reduced penetration resistance, indicating that roots could more easily penetrate through the soil where high-carbon char had been added. In addition, results from one of the fields near Scottsbluff (W2 field) showed a significant increase in soil water content. At the degraded site near Sidney, total carbon content increased by 90% with 9,000 lbs per acre and 149% with 18,000 lbs per acre of high-carbon char application compared with control (no high-carbon char) plots.
