“…1990). About a half of China's maize production and a third of its soybean production come from the highly productive Black Soil in NE China (Duan et al 2011;Liu et al 2011). Maize-maize-soybean rotation increased organic nitrogen content in soil with the same fertilization compared with continuous cultivation of maize, which corroborates with previous findings from various rotation studies (Al-Kaisi et al 2005;Ahmad et al 2014).…”

Yan L., Li H., Zhang J., Zhang Z., Zhu P., Gao Q., Lu W. A long-term (18 years) effect of different fertilization and tillage management practices-fallowing treatment (no fertilizer, no cultivation); CK (no fertilizer, cultivation); N (nitrogen fertilizer); NP (nitrogen and phosphorus fertilizer); NK (nitrogen and potassium fertilizer); PK (phosphorus and potassium fertilizer); NPK (nitrogen, phosphorus, and potassium fertilizer); M1NPK (chemical fertilizer plus manure); 1.5M1NPK (1.5 times M1NPK); NPKS (mineral fertilizer plus straw); Rot (3-year crop rotation of maize-maize-soybean with M1NPK), and M2NPK (2 times manure plus mineral fertilizer) -on the content of total nitrogen and organic forms of nitrogen and the nitrogen content in different particle-size fractions were studied in topsoil (0-20 cm) in Black Soil of NE China by using the methods of Bremner. The results showed that the combined application of organic and mineral fertilizers could significantly increase the contents and proportions of total nitrogen and organic nitrogen forms in soil. Comparing to CK treatment, the content of total nitrogen and hydrolyzable nitrogen increased in the fallow and organic materials treatments. Compared with M1NPK treatment, rotation was more beneficial to increasing organic nitrogen content, especially remarkably increasing amino acid nitrogen. The nitrogen response of sand, silt, and clay was most sensitive on manure; the effects of fallow and manure treatments on sand were notable, the nitrogen content in sand with NPKS increased by 40.86% compared with CK treatment. Our results imply that fallow/rotation managements, and manure/straw application can improve soil fertility.

“…The soil erosion conditions of the Mollisol region are different from those of other regions. The most of the landscape is the long slope length with gentle gradient, while long slope length can produce more confluence rates and gentle gradient also causes severe soil erosion (Cui et al 2007;Liu et al 2011). …”

Rainfall intensity and inflow rate effects on hillslope soil erosion in the Mollisol region of Northeast China

Soil erosion in the Mollisol region of Northeast China is increasingly severe and directly affects national food security and sustainable development. However, few attempts have been made to create a clear distinction between the effects of rainfall and inflow on hillslope soil erosion. A laboratory study was conducted to discuss the roles and contributions of rainfall intensity and inflow rate to hillslope soil erosion and to fit equations based on variations of rainfall intensity and inflow rate (RI ? IR) for soil erosion. A soil pan (8 m long, 1.5 m wide and 0.6 m deep and with an adjustable slope gradient of 0°-35°) was subjected to designed rainfall intensities (0, 50 and 100 mm h -1 ) and inflow rates (0, 50 and 100 mm h -1 ). The results showed that the effects of RI ? IR treatments on hillslope soil loss were significantly greater than those on runoff. Furthermore, the effect of rainfall intensity on hillslope soil loss was significantly greater than the effect of inflow rate. Under the same total water supply, an increase in rainfall intensity resulted in greater average soil loss rates and stronger fluctuations in soil loss than an increase in the inflow rate. The occurrence of rill erosion significantly increased sediment transport capacity on the hillslope, which resulted in an increase in soil loss. Utilizing rainfall intensity and inflow rate, runoff and soil loss equations were generated and validated, and the performances of the two equations were satisfactory. Furthermore, it was determined that both equations are most applicable to the prediction of hillslope soil erosion under long rolling hillslope conditions. For the Mollisol region of Northeast China, the key factor affecting soil erosion on hillslopes is soil particle dispersion caused by rainfall. Therefore, taking measures to cover the soil, such as corn straw mulching, would effectively reduce rainfall erosivity and have significant positive effects on soil erosion prevention and control.

“…The sequestration of soil organic carbon (SOC) contributes to improvement in soil fertility of agricultural land and mitigation of greenhouse gas emissions (Lal, 2004;Johnson et al, 2007;Karlen et al, 2013). The Mollisols in northeast China are losing soil in certain areas because of erosion related to continuous cultivation under poor management that causes losses of C, which affects the productivity of agricultural soil (Quinton et al, 2010;Liu et al, 2011). In addition to the soil's inherent properties (i.e.…”

Better understanding of the effects of land use and agricultural management on organic carbon (C) sequestration is needed to optimize the restoration of fertility in degraded soil, maintain agricultural sustainability and mitigate emissions of greenhouse gases with C sequestration. Most current studies of C sequestration focus on mature soil, whereas there has been little research on soil development from C‐poor parent material. The aim of this study was to assess soil organic carbon (SOC) stocks and C sequestration rates during the early stages of development of a Mollisol from parent material under different types of vegetation, fertilizer application regimes and organic matter inputs, and to compare the results with C sequestration of a mature Mollisol under similar management. Carbon stocks were recorded from 2004 to 2012 in the parent material of a Mollisol under natural fallow (NatF), alfalfa (Medicago sativa L.) (Alfa) or soya beans (Glycine max (Merrill.) L.) and maize (Zea mays L.) (S–M) rotations with and without fertilizer application and crop residues returned or removed at harvest. There was a positive non‐linear relation between C inputs and SOC stocks; increases in SOC stocks decreased with larger additions of C. After 8 years of treatments, the SOC stocks at 0–20‐cm depth had increased in the order S–M + fertilizer + all residues returned (61%) > Alfa (60%) > S–M + fertilizer + part of residues returned (50%) > NatF (30%) > S–M + fertilizer without residue return (17%) > S–M without fertilizer or residue return (7%). These increases in SOC stocks corresponded to annual C sequestration rates of 0.02–0.83 Mg C ha−1 year−1. In contrast, SOC stocks in the 0–20‐cm layer of the mature Mollisol changed little under similar treatments in a wheat (Triticum aestivum L.)–maize–soya bean rotation. Our results have practical implications for how vegetation and agricultural practices could be used to optimize soil restoration and C sequestration in a temperate continental monsoon climate. Highlights What management practices and vegetation lead to carbon sequestration during soil development? Use of a subsoil (parent material) to study soil development. Carbon stocks increased as much in alfalfa as in soya bean–maize rotations with residue return. Perennial legume systems sequester carbon comparable to annual systems with larger carbon inputs.
