Summary: Forest soil acidification caused by acid deposition poses a serious threat to the forest ecosystem. A three-year field experiment in Southern China showed that the surface application of biomass ash and alkaline slag significantly increased soil pH, reduced exchangeable acidity and active Al, and increased exchangeable Ca2+ and Mg2+ in the topsoil. Alkaline slag was more effective than biomass ash in ameliorating soil acidity and alleviating soil Al toxicity in the subsoil.

Summary: Agricultural lime can improve the productivity of acid tropical soils, but the optimal lime rates are still uncertain in many tropical regions. To estimate lime rates, several lime requirement models based on soil data have been developed. In this study, we reviewed seven existing models and introduced a new model (LiTAS), and evaluated their accuracy in predicting lime requirements for different soil types. The foundational models targeting acidity saturation and base saturation were more accurate than the derived models, and the LiTAS model was the most accurate.

Summary: This study evaluated the effects of dolomitic lime and phosphogypsum applications on soil chemical attributes, plant nutrition, and grain yield in direct-seeded flooded rice. Liming alleviated topsoil acidity and increased soil pH, while phosphogypsum application increased nutrient availability throughout the soil profile. Overall, phosphogypsum application improved rice yield by 10-11% by increasing SO4-S availability in the soil profile.

Summary: The study revealed considerable loss of plant nutrients in fertilized grassland soil of non-allophanic Andosol over half a century, with increased soil acidity and pH at depths of at least 100 cm. Soil available P also increased at depths of 80 to 100 cm. Measures should be taken to reduce nutrient loss for sustainable agriculture and environmental conservation.

Summary: Soil acidification is a global issue that poses a serious threat to food security and agricultural sustainability. Calcium lignosulfonate (CaLS) has been found to be an effective amendment for acid soils, as it increases soil pH, exchangeable cations, cation exchange capacity, and organic carbon content, while reducing acidity, especially exchangeable aluminum content. The mechanism involves the displacement of H+ and Al3+ off soil colloids by Ca2+, leading to the leaching of these ions in soluble organo-aluminum complexes. CaLS also promotes the transformation of exchangeable aluminum and low-to-medium organo-aluminum complexes into highly stable organically bound fractions, immobilizing them in the soil.

Summary: Manure amendment has been proven effective in preventing or reversing soil acidification in red soil. However, an integrated approach combining manure with chemical fertilizers is needed to maintain soil productivity and nutrient balance, while reducing heavy metal accumulation and environmental risks. Incorporating 40% or more of total nitrogen from manure can help prevent acidification and provide necessary phosphorus, but additional potassium inputs are necessary for balanced plant nutrient supply.

Summary: Biochar amendments increased total soil carbon by 71%, 182%, and 210% for B30, B60, and B90, respectively. The application of biochar at different rates significantly increased the subsoil inorganic carbon (SIC), mainly occurring in the subsoil below 1 m. The study provided critical knowledge on the impact of biochar application on carbon stocks in subsoil in the long term.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

Summary: Conservation agriculture with three management principles is effective in mitigating soil erosion and nutrient loss. This study found that no tillage significantly increased soil extracellular enzyme activities, while legume incorporation only had a significant effect on phosphorus-acquiring enzymes. Crop diversity positively influenced the no tillage-induced increase in enzyme activities.

Summary: This study investigates the structural strength of the Loess-Paleosol Sequence (LPS) and finds that the strength tends to increase with burial depth, with the loess layer weaker than the paleosol layer. The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.

Summary: Agricultural intensification has led to severe degradation of croplands in China. Converting degraded croplands to grasslands can increase soil organic carbon and nitrogen content, but may decrease soil pH and available phosphorus. The duration of conversion and mean annual precipitation are major factors influencing soil changes.

Summary: This study linked soil pore structures quantified by X-ray computed tomography (CT) scanning and infiltration processes traced using stable hydrogen and oxygen isotopes under different land uses in the red soil region of southern China. The results showed that soil pore characteristics mainly affected soil water transport, while other soil properties played more important roles in soil water retention. CT-based porosity and soil texture were considered crucial indicators in the evaluation of water exchange during infiltration processes.

Summary: This study systematically analyzed the effects of drought on terrestrial ecosystem C-N-P stoichiometry on a global scale. The results showed that drought significantly decreased the C:N ratio in soil, enzymes, shoots, and roots. Soil microbes were limited by N, whereas plants were restricted by P under drought stress. Drought intensity and duration were negatively correlated with shoot N:P and vector angle.

Summary: Based on the application of the integrated wind erosion modeling system, this study comprehensively simulated the loss and conservation of nutrients during aeolian dust emissions in the arid and semiarid areas of China. The results showed a decreasing trend in nutrient losses over the past two decades, with the ecosystems playing a crucial role in preventing these losses. The prevention rates of different land cover types were generally high, indicating the effectiveness of conservation measures.
