The Impact

Inappropriate tillage and soil compaction threaten farmland sustainability in the Huang-Huai-Hai Plains of China. We aimed to explore the impact of plowing tillage, rotary tillage, strip rotary tillage, and strip rotary tillage coupled to a two-year subsoiling interval (STS) on soil quality at various soil depths and on wheat yield. Soil bulk density was substantially lower in the 30–45 cm depth under STS than under any other treatment, resulting in lower soil penetration resistance. Highest soil particle macro-aggregation was observed under STS in the 15–45-cm soil layer.Consistently with greater nutrient availability, key enzymes associated with soil fertility (urease, invertase, phosphatase, and catalase) showed higher activity in STS plots. Concomitantly, highest yields were recorded for STS at 10 451 and 10 074 kg/ha in 2014–2015 and 2015–2016, respectively. STS significantly improved soil physical structure and enhanced soil enzyme activity, thereby stimulating soil nutrient release and increasing winter wheat yield.

Taking four types of slopes as test objects this paper measured their, soil nutrient and soil enzyme activity. The results showed that variation of soil nutrients in different slopes is obvious; soil enzyme activity is also a significant difference between different slopes. The soil of A slope (natural secondary forest ) was the highest in activity of urease, invertase, neutral phosphatase and catalase, the lowest in D(wasteland)slope except catalase. There were extremely significant positive correlations among soil urease activity, invertase activity and neutral phosphatase activity. Significant positive correlations were observed between soil urease activity, invertase activity, neutral phosphates activity and organic matter, available N, total N. It suggested that enzymatic activity could be used to indicate and estimate soil fertility of artificial remediation slopes. Combined with and community structure and community characteristics of vegetation on the sanmpled slops, soil enzyme activities could be used to measure the degree of vegetation restoration in the disturbed area.
