Summary: Soil acidification and base cation loss are significant problems in the subtropical red soil region of China, particularly in agroecosystems with high nitrogen fertilization. This study assessed the current status and future risk of soil acidification in a typical agricultural watershed using a two-year monitoring approach. The results showed that while significant soil acidification occurred, surface water acidification was minor, indicating the buffer capacity of the soils. However, there was a substantial loss of base cations, depleting the exchangeable pool in the watershed and posing a serious threat to soil recovery from acidification.

Summary: Chloride is a micronutrient necessary for plant growth, but long-term application of chlorinated fertilizers can introduce significant amounts of Cl- into farmland ecosystems. This study found that the long-term application of chlorinated fertilizer increased the Cl- content in the soil, reduced soil pH, cation exchange capacity, and exchangeable alkali ions, and increased the risk of aluminum toxicity. Additionally, the content of exchangeable calcium and magnesium ions in the soil was significantly reduced. Therefore, it is recommended to avoid long-term application of high chloride fertilizers in agricultural production.

Summary: In the last 30 years, severe soil acidification has been found in China due to acid deposition and nitrogen fertilizer overuse. Understanding the spatial pattern and vertical variations in base saturation percentage (BSP) and exchangeable cations (Ca2+, Mg2+, K+, Na+, H+ and Al3+) can directly benefit fertilization management and ecological protection.

Summary: This study investigates the effect of lime on soil potassium changes in agroecosystems by conducting a meta-analysis and a long-term experiment. The results show that lime application significantly reduces topsoil exchangeable potassium content globally, and the impact depends on various factors such as soil properties, crop types, fertilizer regimes, and experiment types. Lime application mainly decreases soil exchangeable potassium due to increased crop uptake and transformation to non-exchangeable form. The study highlights the importance of lime in potassium management and emphasizes the role of initial soil potassium levels and acidification degree in regulating subsoil potassium extraction by crops under lime application.

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: Soil function assessment is important for mitigating soil degradation and achieving sustainable use of soil resources. This study investigated the spatial variation of soil functions with land use type and slope position in a small agricultural watershed. The results showed significant variations in soil properties and functions between different land use types and slope positions. Soil erosion was found to be the dominant process affecting soil functions by altering soil properties. Measures promoting nutrient accumulation and controlling soil erosion should be implemented to enhance soil functions. These findings are valuable for designing soil and water conservation measures in agricultural watersheds to enhance ecological services.

Summary: This study aimed to evaluate the impact of biophysical conservation measures on the dynamics of land use and land cover in the highlands of Ethiopia. The results showed that cultivated land had the largest coverage, with bunds built on cultivated land accounting for 93% of conservation practices. There was a significant decline in the implementation of biophysical conservation practices in each district during the study period.

Summary: Soil acidification is a challenge to food security due to the production of toxic free aluminum ions. This study investigated the effect of different minerals and organic matter on the exchangeable aluminum ions during soil acidification. The results showed that montmorillonite consumed more acid than kaolinite due to its larger cation exchange capacity. Additionally, the presence of more organic matter in Ultisols improved their acid buffering performance and inhibited the mobilization of aluminum ions.

Summary: Logging and plantation agriculture are crucial for tropical nations like Papua New Guinea, but they can lead to hydrological changes and increased sediment, nutrient, and pesticide runoff, affecting downstream habitats. Effective catchment management, such as avoiding steep slopes, expanding buffer zones, minimizing chemical use, and monitoring, can reduce sediment and related impacts.

Summary: This study investigated soil acidification in the Pearl River Delta of China, focusing on the effects of land-use change and parent materials. Results showed that soils derived from granite exhibited higher acidity and lower pH buffering capacity compared to those derived from alluvial sediment. Significant soil acidification was observed under land-use change in vegetable lands and orchards, but not in paddy fields. The study suggests that soil acidification induced by land-use change is influenced by parent materials.

Summary: The study found that application of iron chelates to tropical soils did not significantly reduce Fusarium wilt in banana plants. The presence of high iron availability in the soils overwhelmed the treatments' capacity to alter iron availability to the host plant and pathogen. Additionally, the application of strong chelating ligands led to changes in plant tissue concentration of aluminium and manganese, with potential detrimental effects.

Summary: Since human settlement, nutrient cycles in Pacific Island have been modified. Modern agriculture intensification has caused further changes. The budgeting calculation shows nutrient imbalances in all countries, with agricultural lands exporting nitrogen, phosphorus, and potassium. However, the calculation did not consider all nutrient losses, so the actual nutrient fluxes may be greater.
