Summary: Harsh environmental conditions and poor management of agricultural fields in the tropics lead to rapid soil degradation and low crop yields. Crop simulation models offer tools for assessing the degradation problem and support improved management decisions, but their wide-scale application in the tropics lags due to limited resources for data collection and specific data requirements.

Summary: Tillage on slopes thins soils and reduces crop yields. The duration and intensity of tillage erosion gradually decrease crop yields at the landscape scale. To prevent further decline in yields, widespread adoption of no-tillage practices and avoidance of down-slope cultivation are necessary.

Summary: This study used the CROPGRO-Soybean model to simulate the production potential of rainfed soybean in northeast Nigeria. The results showed that the simulated yield of TGX1951-3 F variety was above a threshold of 1500 kg/ha in several locations, suggesting its suitability for cultivation in that region. The study also found that the yield performance of soybean is dependent on location, variety, and sowing window.

Summary: This study found that certain indicators of soil health, including POXC, Min C, PMN, and ACE-N, are closely related to soybean yield. Factors such as soil texture and drainage class have a significant impact on these indicators, as well as management factors like crop rotation and manure use. The study emphasizes the importance of considering regional factors when developing soil health benchmarks.

Summary: Terracing of hillslopes can lead to gully erosion, as observed in the Black Soil Region of Northeast China. Improperly designed terraces can cause runoff concentration and eventually result in gully incision. Proper countermeasures are suggested to prevent further soil loss and land degradation on abandoned terraced hillslopes.

Summary: Soil erosion in croplands has a significant impact on global carbon cycling, leading to the loss of soil organic carbon. However, the soil organic carbon stock can be restored after erosion stops. Simulation results suggest that erosion reduces carbon inputs from crop residue and restricts heterotrophic respiration in eroded soils.

Summary: Soil erosion in agricultural landscapes, particularly in the Corn Belt of the midwestern United States, has led to a significant loss of A-horizon soil, affecting crop yields and causing economic losses. This research reveals that tillage-induced erosion plays a crucial role in soil loss, which has been significantly underestimated by previous soil survey-based methods. Models used to assess nationwide soil loss trends in the United States do not simulate tillage erosion, highlighting the need for improved erosion prediction and management strategies.

Summary: This experiment investigated the effects of biofertilizers, lime, and inorganic NPSB fertilizers on the nodulation, growth, and yield of soybean. The results showed that these factors and their interactions significantly influenced the number of effective nodules, leaf area index, and grain yield. Specific combinations of biofertilizers, lime, and inorganic fertilizers resulted in the highest grain yield in Assosa and Bambassi districts.

Summary: The major challenge of growing soybean is the lack of quality inputs and the deterioration of crop productivity and soil environment. Soybean crop intensification system can improve yields and soil environment, but its contribution to crop productivity is not well understood due to different genotypes showing different responses.

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.

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.

This study found that incorporating organic matter, especially biowaste compost, into the subsoil significantly increased root growth and subsequently improved crop nutrient uptake, biomass, and grain yield. The incorporation of green waste compost had less pronounced effects.

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.
