“…According to Figure a, temperature (including the daily maximum and minimum temperature) was negatively correlated with the observed SOC content, with the daily minimum temperature having a weaker effect than the maximum temperature. Increased temperatures promote soil warming, and warming significantly decreases SOC contents (Fang, Smith, Moncrieff, & Smith, ; Qi et al, ). Increased levels of soil respiration and mineralized C associated with increasing temperature may be responsible for SOC consumption (Allison, Wallenstein, & Bradford, ; Hou, Ouyang, Maxim, Wilson, & Kuzyakov, ; Lefèvre et al, ; Wu, Dijkstra, Koch, Peñuelas, & Hungate, ).…”

The Loess Plateau is considered one of the world's regions with severe soil erosion. Grasslands are widely distributed on the Loess Plateau, accounting for approximately 40% of the total area.Soil organic carbon (SOC) plays an important role in the terrestrial carbon cycle in this region.We compiled more than 1,000 measurements of plant biomass and SOC content derived from 223 field studies of grasslands on the Loess Plateau. Combined with meteorological factors (precipitation and air temperature) and the photosynthetically active radiation factor, the topsoil SOC contents of grasslands were predicted using the random forest (RF) regression algorithm. biomass and temperature should receive more attention due to increasing C sequestration.

“…Therefore, labile OM fractions containing labile organic C (LOC) and N (LON) are commonly used as early indicators for assessing soil quality in response to nutrient management practices (Wander, ; Yang et al ., ). Generally, soil LOC and LON fractions can be greatly affected by fertilizer application, tillage, irrigation and temperature (Qi et al ., ; Zhang et al ., ). In particular, application of organic substrates can stimulate the soils microbial activity, enhancing the decomposition of organic materials with rapid release of soil LOC and LON fractions (Löhnis, ; Qi et al ., ; Yang et al ., ).…”

We investigated the effects of compost (CM), made from poultry and cattle manure with spent mushroom substrate, plus chemical fertilizers (CFs) on soil organic carbon (C) and nitrogen (N) fractions in silty loam soil of the Loess Plateau. Eight fertilizer practices were applied in a 7‐year‐old ‘Red Fuji’ apple (Malus domestica Borkh.) orchard for 360 days. Compared to CM alone, CM–CFs decreased slightly soil total organic C but increased total N by 4.3–11.6%. Notably, CM–CFs increased soil microbial biomass C (MBC) by 2.7–26.5% and microbial biomass N (MBN) by 7–13.7%. Soil water‐soluble carbon (WSC) was increased by 20.7% and 19.2% when 2% CM plus N and phosphorus (P) (2%M–NP) and 4% CM plus N and P (4%M–NP) were applied, respectively. Whereas 0.5% CM plus N and P (0.5%M–NP) increased WSC by 9.3% on day 30 but decreased it by 7.2% from 30–360 days. Hot water‐soluble C increased by 13.1–14.6% from 0–180 day, but thereafter, the effect disappeared. Compared to CFs, CM–CFs increased MBN by 35.1–115.6%, and increased alkali‐hydrolyzable‐N by 3.5–55.8% over 180–360 days of incubation. Additionally, CM–CFs promoted N mineralization, increasing NH4‐N and NO3‐N contents. Based on the changes in C and N fractions and available nutrients, 2%M–NP (45 t/ha of CM plus 450 kg/ha of N and 157.5 kg/ha of P) may be the optimal fertilizer strategy for stimulating soil microbial growth and activity, and enhancing nutrient cycling for apple growth.

“…This suggests that agricultural land use has changed dramatically and the traditional cropping system and crop rotations have been converted into other methods associated with great changes in management practices. For example, vegetable production in China has increased rapidly in recent years, and many fields with a traditional crop rotation (e.g., rice–wheat/ Brassica napus rotation) have been converted to vegetable production to meet the demand for vegetables caused by the increasing population and urbanization (Hao, Sun, & Zhao, ; Qi et al, ; Xu et al, ). Many studies have been conducted to compare the SOC contents among different agricultural land use patterns, but the impact of the historical processes of land use change on SOC dynamics has received less attention (Davy & Koen, ; Qi et al, ).…”

The properties of soil organic carbon (SOC) required for carbon sequestration and nutrient availability are contradictory, and the changes in SOC caused by agricultural land use changes remain elusive. Data on the total soil organic carbon (TOC) and labile organic carbon, including easily oxidizable organic carbon (EOC), dissolved organic carbon (DOC), and microbial biomass carbon (MBC), of the soil profile were analysed for four typical agricultural land use scenarios in the Chengdu Plain, China. The impacts of agricultural land use changes on sequestration and nutrient availability of SOC were assessed in this urban agricultural area using the space‐for‐time substitution method. Conversion of land use from a traditional agricultural rotation (rice‐wheat/rapeseed rotation) to afforestation increased the MBC content and decreased the contents of EOC, DOC, and TOC due to the lower input of organic matter, improved aeration of the soil profile, and growth of aboveground biomass. Conversion of a traditional rotation to a rice–garlic rotation resulted in a significant increase in topsoil TOC, slight but insignificant decreases in subsoil TOC, and clear increases in labile organic carbon because of rice planting, rice straw mulch, and reasonable application of chemical fertilizers. In contrast, the conversion of a traditional rotation to a rice–leafy vegetable rotation decreased MBC due to the excessive use of chemical fertilizers that consequently increased EOC, DOC, and TOC. We conclude that afforestation on paddy soil has negative consequences for soil carbon sequestration and a rice–leafy vegetable rotation contributes to carbon sequestration but is detrimental to soil fertility. In addition, the MBC ratio in soil could be the optimal indicator for assessing SOC stability and soil fertility, and more attention should be paid to subsoil carbon changes.
