Abstract. Soil salinity and sodicity caused by saline water irrigation are widely observed globally. Clay dispersion swelling influenced sodium (Na+) concentration electrical conductivity (EC) of soil solution. Specifically, potassium (K+) also significantly affects structural stability, but for which concern was rarely addressed in previous studies or practices. A column experiment carried out to examine the effects with different relative concentrations K+ Na+ (K+ / Na+), including 0:1...
The traditional view of Na+ as harmful and Ca2+ beneficial doesn't always apply in multi-cationic soil solutions. Initially, adding promotes leaching, reducing salinity, but excess becomes counterproductive. As leaches, the soil's Ca2+-Na+-Mg2+ mix shifts to Ca2+-K2+-Mg2+, Ca2+'s function changes, even causing opposite effect. To investigate complex mechanism Na+-Mg2+ K+-Mg2+, we conducted an indoor column experiment using saline water (4 dS m−1) with different cation compositions...
Combining organic and inorganic fertilizers is critical for increasing yield improving soil fertility. However, the specific effects of this combination on greenhouse gas (GHG) emissions in hilly apple orchards remain unclear. Furthermore, studies slope agriculture often overlook runoff, a significant factor to consider. Hence, we conducted two-year field trial orchard north Shaanxi investigate impact practical measures GHG emissions, yield, fruit quality. Three management practices were...

However, the effect of combined on GHG emissions in hilly apple orchards not clear. Furthermore, studies slope agriculture mostly ignore runoff. Hence, a two-year field experiment was conducted orchard north Shaanxi to explore effects management practices surface water temperature, runoff, fruit quality. Three were implemented: (1) chemical...

Nitrate leaching has been widely studied in agricultural cropping systems, whereas there are few studies on dissolved organic nitrogen (DON) leaching. Moreover, the factors determining variation of DON arable systems remain unclear. Here, we examined variations from two crop rotations (Organic with Green Manure (OGM) and Organic Grain Legume (OGL)) one conventional rotation (Conventional (CGL)) without use cover crops manure application. These treatments were part long-term experiments...
Organic substitution is an effective approach to solve the problems related excessive application of chemical fertilizers, especially in saline areas, where growers often over apply fertilizers avoid salt-induced crop failure. The purpose this study was evaluate effects organic proportions on soil properties, sunflower ( Helianthus annuus L.) growth, and yield arid area. A two-year field experiment conducted Hetao Irrigation District (HID), northwest China during growing season 2019 2020. On...
Organic substitution (partial of chemical fertilizer with organic fertilizer) is an effective approach to solve the problems soil degradation caused by excessive application fertilizers, especially in saline areas. The purpose this study was evaluate effects different proportions using made from agricultural wastes on saline-sodic properties and sunflower (Helianthus annuus L.) growth arid area. A two-year field experiment conducted Hetao Irrigation District, northwest China during growing...
