“…AAN is closely related to the turnover of roots, root exudates, and microbial metabolites (Li et al, 2014; Tian et al, 2017). Mechanical compaction leads to a reduction in soil capillary porosity, which hinders the movement of water, gas, and heat in the soil (Li, Zhu, et al, 2021; Luz et al, 2022) and indirectly affects the activities of soil microorganisms and plant roots (Ge et al, 2020), which in turn leads to a reduction in AAN content. Natural grassland is uncultivated, which facilitates the conversion of SON into AMN and AAN, which have relatively simple structures and high availability, and the potential supply of nitrogen under natural grassland is better than that of farmland.…”

“…The study area has a cold temperate continental climate, with a maximum temperature of approximately 36°C and an average annual temperature of 0.4°C (Li, Yao, et al, 2021; Li, Zhu, et al, 2021). The annual rainfall is 500–600 mm, and rainfall is mostly concentrated in July and August (Li, Yao, et al, 2021, Li, Zhu, et al, 2021). The terrain of this area is characterized by an upland region with an altitude of 267–300 m. The soil, commonly known as the typical black soil, belongs to Isohumisols according to the Chinese Soil Taxonomy and to Mollisols using the U.S.…”

Soil organic nitrogen (SON) accounts for more than 90% of the total nitrogen (TN) in black soil and is one of the most important indicators of soil fertility.However, the effect of land-use changes on SON fractions is still unclear in black soil. Hence, natural grassland (uncultivated), farmland (converted from natural grassland), and artificial forestland (grain plots converted into forests) in the black soil region of Northeast China were selected for research. TN, available nitrogen (AN) and SON fractions (ammonia nitrogen (AMN), amino acid nitrogen (AAN), hydrolysable unknown nitrogen (HUN), acid insoluble nitrogen (AIN)) in the topsoil (0-20 cm), and subsoil (20-40 cm) were analysed and compared with elucidate the effects of land-use changes on SON fractions. The results showed that compared with natural grasslands, the contents of TN and

“…China ranks among the countries that are suffering from the most serious soil erosion [ 7 ]. Prevention and control of soil erosion not only maintain the harmony between humans and nature, but also are strategies for sustainable development [ 8 , 9 , 10 ]. As a key water source in Beijing, the Miyun reservoir is pivotal for water security maintenance.…”

“…Overground and underground hedgerows contribute to 62.25 and 37.75% of runoff reduction along with 60.44 and 39.56% of the sediment reduction advantages on average, respectively [ 18 ]. In the black soil region of northeast China, the runoff and sediment reduction benefits brought about by hedgerows were 5.40–10.16% and 51.90–75.72%, respectively [ 8 ]. Contrastingly, on the red-soil slope land in southern China, the hedgerows reduced the average runoff and soil erosion by 65.87 and 91.29% under normal rainfall conditions [ 19 ].…”

Soil erosion of sloping farmland in the Miyun reservoir area in Beijing has become a serious issue and has threatened the ecological environment and safety of the reservoir area. We used the Taishizhuang Village Non-point Source Pollution Prevention & Control Base in the Miyun reservoir as a study area and performed a comparative analysis of the physicochemical properties of soil of the upper, middle, and lower slopes of the Scutellaria baicalensis + Buchloe dactyloides plot (Treatment 1, T1), Morus alba + Buchloe dactyloides plot (Treatment 2, T2), Salvia miltiorrhiza + Cynodon dactylon plot (Treatment 3, T3), Platycodon grandiflorus + Cynodon dactylon plot (T4), and a barren land control plot (Control check, CK), to explore how different hedgerow patterns affect the soil’s physicochemical properties, anti-erodibility, and fractal characteristics. We found the following: (1) The primary soil mechanical composition included sand particles in the upper slopes, whereas it was soil fine particles in the middle and lower slopes. (2) The fractal dimension of the slope soil showed a significant negative correlation with sand particles (R2 = 0.9791) while being positively correlated with silt particles (R2 = 0.9635) and clay particles (R2 = 0.9408). (3) All hedgerow patterns increased soil nutrients, with the Morus alba + Buchloe dactyloides hedgerow plot increasing the soil total nitrogen (STN), soil total phosphorus (STP), and soil organic matter (SOM) content by 213.89–282.69%, 55.56–58.15%, and 29.77–56.04%, respectively. (4) The Morus alba + Buchloe dactyloides hedgerow plot significantly decreased the soil erodibility factor K value, improved soil anti-erodibility, and reduced soil erosion. (5) The K value of the soil erodibility was significantly negatively correlated with clay particles, soil fractal dimension, and STP (p < 0.01); positively correlated with sand particles; and negatively correlated with silt particles, STN, and SOM. Therefore, the Morus alba + Buchloe dactyloides hedgerow planting contributes to clay particle conservation, soil nutrient content improvement, soil structure optimization, and soil anti-erodibility enhancement.

“…Erosion occurs due to excessive surface runo , causing the loss of the soil surface layer along with organic matter and nutrients in it [3]. Erosion will change soil characteristics such as particle size, bulk density, speci c gravity, aggregate stability to the hydraulic conductivity of the soil [4,5]. Changes in characteristics due to erosion can reduce soil quality, especially for agricultural ecosystems [6].…”

Biochar, pumice, and mycorrhizae applications using direct testing methods in the field have not been widely carried out. The application of biochar in this study was used as a conservation material to control runoff and erosion. The research was conducted using a field plot during the peak of the rainy season (March-April) of 2021. The study was conducted in areas where the soil material is dominated by clay (>40%) and steep slope angles (>60%). The cropping pattern at the research site is generally cassava in the dry season and corn in the rainy season. Four 1 × 10 m field plots with corn stands were prepared with biochar, pumice, mycorrhizae, and control treatments. Runoff and sediment measurements were carried out by calculating the volume of water and suspension in the storage tank. The effect of three treatments was observed and measured through some soil characteristics such as bulk density (BD), specific gravity (SG), porosity, organic matter content (OM), cation exchange capacity (CEC), and aggregate stability. The highest rainfall in March and April reached 441 mm/month, with the highest intensity reaching 150 mm/week. Under intense rainfall, biochar application provides better performance than pumice and mycorrhizae. Runoff reduction from biochar is the highest, with 51.67%. On the other hand, pumice and mycorrhizae show a lower effectivity in decreasing runoff with 40.15% and 37.92%, respectively. The effectivity on lowering runoff translates to each ameliorant’s performance in reducing soil loss. Biochar decreases soil loss by 50.78%, while pumice and mycorrhizae decrease soil loss by 37.9% and 26.26%. The application of biochar reduced the rate of erosion by altering soil characteristics. Biochar application provides better soil characteristics by reducing BD and SG while at the same time increasing the porosity, OM, CEC, and aggregate stability. The changes provided by biochar can provide means to both soil conservation and increase in soil productivity.
