The phenomenon of sulfur (S) deficiency in Chinese soil is becoming increasingly severe, especially the northeastern saline-sodic wasteland (WL). To determine bioavailability S long-term cultivated paddy with or without organic amendment addition, field experiment site was established and incubation experiments were conducted. Compared to WL, properties have been continuously improved during 15-year (PF) cultivation, ultimately enhancing content carbon (by 242.62 %), total nitrogen 126.49 %)...
Abstract Background Large-scale afforestation can significantly change the ground cover and soil physicochemical properties, especially fertility maintenance water conservation functions of artificial forests, which are very important in semi-arid mountain ecosystems. However, how different tree species affect nutrients properties after afforestation, is best plantation for improving remain largely unknown. Methods This study investigated nutrient contents three plantations ( Larix...
<title>Abstract</title> Soil salinization poses a threat to global food security by deteriorating soil biodiversity and especially various functions. However, how affects the biodiversity-multifunctionality relationship remains largely unknown in agro-ecosystems. Here, we conducted standardized survey of agro-ecosystems across typical gradient at 115 representative agricultural sites, aiming investigate relationships between (encompassing diversity bacteria, fungi, archaea, protists,...
In the past few decades, industrialization has caused a large number of pollutants to be released into atmosphere. Forest ecosystems play an important function in regulating biogeochemistry and circulation metal ions pollutants. affect absorption dissolution nutrients from atmosphere vegetation canopy, thereby influencing content composition forest floor leachate soil solution. This study examined changes acid anions (NO3−, SO42−, Cl−) cations (K+, Ca2+, Na2+, Mg2+, Fe3+, Pb2+, Cu2+, Cd2+)...

Abstract Background: Large-scale afforestation can significantly change ground cover and soil physicochemical properties, especially the fertility maintenance water conservation function of artificial forest is very important in semi-arid mountain ecosystems. To better understand effects different tree growth on nutrient properties following to determine best plantation species for improving functions. Methods : This study investigated contents three ( Larix principis-rupprechtii , Picea...

Soil salinisation is one of the major soil degradation threats worldwide, parameters related to quality and ecosystem multifunctionality (EMF) are crucial for evaluating success reclamation efforts in saline-sodic wasteland (WL). Microbial metabolic limitation also main factors that influences EMF agricultural cropping systems. A ten-year localization experiment was conducted reveal key predictors index (SQI) values, microbial characteristics, different farmland random forest model showed...
Rational reclamation of saline sodic land can recover vast potential resources, effectively relieve food shortages, and realize positive ecological impacts. However, previous investigations have focused on the current ecosystem service (ES) value paddy fields while neglecting costs benefits over long term.We assessed ES values local reclaimed at field scale using primary data collected from 15 different ecosystems. Three models, two coculture nine cultivation periods up to 50 years were set...
The perpetual cultivation of rice within saline-sodic wastelands has been observed to enhance soil nutrient availability and promote microbial growth. Nevertheless, the impacts such a reclamation process on fractions inorganic phosphorus (Pi) in saline sodic soils remain elusive. A comprehensive investigation was undertaken examine transformations Pi that occur subjected long-term cultivation. This study encompassed an analysis chemical properties, fractions, levels phospholipid fatty acids...
The perpetual cultivation of rice within saline-sodic wastelands can enhance soil nutrient availability and promote microbial growth. Nevertheless, the impacts reclamation process on fractions inorganic phosphorus (Pi) in saline sodic soils remain elusive. To study transformations Pi wasteland with long-term plow layer (0-20 cm) different years cultivation, we collected that had undergone 1, 5, 10, 20, 29, 51 cultivation. Along a continuous decrease electrical conductivity (EC), organic...

China is undergoing a rural land system reform called Three Rights Division (TRD) which promotes the transformation of management right and guarantees security contract right. In this paper, we study impacts on migration under market (the ability to rent land) government (land expropriation) mechanism. We employ Probit model with robustness endogenous checks identify whether behavior insecurity have migration. Results show that has positive impact while negative, indicating TRD probability...
