From: Effects of different straw return methods on soil properties and yield potential of maize
Effect of straw return methods on soil physical properties in the early stage of corn growth. DPR, straw incorporation with deep tillage; SSR, straw incorporation with subsoiling NTR, no-tillage mulching straw return; CK, farmer’s shallow rotation. Y, year; T, straw management; L, layer. Lowercase and uppercase letters indicate significant differences between treatments in 2021 and 2022, respectively (p < 0.05), as determined by the HSD test. The values are the means ± standard errors (n = 3).
