The Songnen Plain of the Northeast China is one of the three largest soda saline-alkali regions worldwide. To better understand soil alkalinization and salinization in this important agricultural region, it is vital to explore the distribution and variation of soil alkalinity and salinity in space and time. This study examined soil properties and identified the variables to extract soil alkalin...

The real-time monitoring and driving force research of soil salinization in semi-arid grassland are great significance for regional local ecological environment protection, management, sustainable development. We selected a typical “mine-town-agriculture-pastureland-industry” interlaced ecologically fragile area as the study area. Based on method SI (Salinization Index)-Brightness feature space...

Purpose: to analyze the experience of domestic and foreign scientists in using various types land reclamation restore increase fertility degraded soils under irrigation rainfed conditions. Discussion. The overview research papers, literary sources, concerning impact on restoration is presented. options for reclamation, depending type degree soil degradation are considered. timely application (h...

Soil salinity is a major abiotic stress adversely affecting plant growth and crop production worldwide. Increased salinization of arable land is expected to have destructive universal effects, resulting in 30 % land loss within the next 25 years and up to 50 % by the middle of twenty-first century (Porcel et al. 2012; Kapoor et al. 2013; Abdel Latef and Chaoxing 2014). The term ‘‘salinity’’ ref...

Soil salinization is closely related to land degradation, and it supposed exert a significant negative effect on soil organic carbon (SOC) stock dynamics. This its mechanism have been examined at site transect scales in previous studies while over large spatial extent, the salinity-induced changes SOC space time less quantified, especially by machine learning remote sensing techniques. The main...
