Fig. 1. Means of total organic C content, total and dilute acid-extractable polysaccharides, and total N content in different water-stable aggregate-size classes isolated after cover crop growing period in the field study. Vertical bars represent standard error of the means. The means with same letters above the error bars in the same organic components are not significantly different at p < 0.05. TOC, total organic C; TPS, total polysaccharides; DAEPS, dilute acid-extractable polysaccharides; TN, total N.
