Summary: Modern agricultural systems heavily rely on inorganic nitrogen fertilization to increase crop yields, but excessive use of nitrogen can have negative impacts on soil properties, leading to acidification, depletion of phosphorus and potassium, and changes in soil bulk density. While N fertilizer significantly increases corn yield compared to unfertilized controls, long-term use of monocultures can potentially lead to nitrogen losses to the environment.

Summary: The use of a double inhibitor can significantly reduce nitrogen losses and improve nitrogen use efficiency, especially under short-term no-tillage management conditions. Compared to urea without inhibitors, the double inhibitor not only reduces losses of ammonia and nitrous oxide, but also increases crop uptake efficiency of nitrogen.

Summary: Soils store a significant amount of carbon in the form of decomposing organic matter, making it crucial to understand the factors that influence the incorporation of organic matter into the soil. A study was conducted in 16 different ecosystems in Navarre, Spain to examine the interactions between vegetation cover, climate, and soil factors. Results showed that vegetation cover type, soil C/N ratio, and precipitation influenced decomposition rates and stabilization factors. The study highlights the complex relationship between environmental factors and soil carbon flows, emphasizing the importance of ecosystem changes in carbon dynamics.

Summary: Regenerative Agriculture is gaining prominence as a solution to the crises facing agriculture, but there are controversies surrounding some of its practices. It draws support from various sectors but also raises questions about the context-specific benefits. The resurgence of interest in Regenerative Agriculture represents a re-framing of approaches to agricultural futures but may also contribute to confusion in the public debate.

Summary: In recent years, the Tsitsikamma region in South Africa has seen a shift from conventional tilled single pastures to minimum tilled mixed pastures. However, the storage of soil organic matter (SOM) under minimum tilled mixed pastures has not been quantified. This study evaluated SOM indices in the upper 60 cm soil of six-year-old mixed pastures in the Upper and Lower Tsitsikamma regions. The results suggest that integrating manure into minimum tilled pasture mixtures can promote SOM storage, but site-specific management strategies are necessary.

Summary: The study found that nitrogen additions enhanced the rate of soil organic phosphorus mineralization in semi-natural grasslands, with alkaline phosphatase (ALP) activity being the main driver controlling soil organic phosphorus mineralization rates under nitrogen additions. The interaction between plants, soil, and microbes plays a crucial role in maintaining the supply of phosphorus and driving soil organic phosphorus mineralization in phosphorus-deficient ecosystems as nitrogen deposition increases.

Summary: Biochar can either boost or suppress rice growth, depending on the ratios of carbon and nitrogen and available nitrogen to available phosphorous. The response of rice growth to biochar application follows an exponential-growth function in high organic carbon (OC) soil, while an inverted U-shaped curve in low OC soil. The optimal C:N ratio for highest rice growth is between 20 and 30. Biochar can increase total biomass, but may also cause nitrogen deficiency. The applied biochar rate should be determined based on soil properties for optimal rice growth.

Summary: The study shows that nitrification is a major driver of soil acidification in Acacia plantation or fertilized oil palm plantation. Soil organic matter accumulated under Imperata grassland or Macaranga forest can partially neutralize the acidity generated by nitrification, mitigating soil acidification in these areas.

Summary: In this study, drip irrigation and intercropping were used to improve the efficiency and economic benefits of phytoremediation of arsenic-contaminated soil. The impact of soil organic matter (SOM) on phytoremediation was also investigated, showing that peat inhibited the upward migration of arsenic and increased the phytoavailability of arsenic under drip irrigation conditions. Drip irrigation coupled with intercropping enhanced phytoremediation, and the addition of soil organic matter further improved the efficiency of phytoremediation.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

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.

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.

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.
