Summary: Soil emissions of nitrous oxide (N2O) in Australian semi-arid cropping systems can be further reduced by incorporating legumes into cereal-based rotations. Practices such as no-till systems and product removal (cutting for hay or harvesting for grain) can optimize mitigation of N2O emissions derived from legumes in such systems.

Summary: This paper analyzes the impact of climate change and groundwater quality on drought behavior in a semi-arid area of northeastern Mexico. The results show that there have been mild to moderate droughts in the past 20 years, significantly affecting rainfed farmers. The study also reveals issues with water quality, as salinity conditions in irrigated areas pose a risk to agricultural production.

Summary: Conservation agriculture management practices, such as cover crops and residue retention, have been found to improve soil quality and environmental sustainability in dryland cropping systems. The long-term adoption of cowpea cover crops could be a potential practice to sustain crop productivity with environmental co-benefits, especially in the wetter regions of southeast Australia.

Summary: This study focuses on the replenishment of groundwater in a semi-arid region in Tanzania, showing that focused recharge from ephemeral stream discharges is critical. Groundwater level rises correspond better to pulses of stream discharge from intensive rainfall than from seasonal rainfall. Stable isotope ratios of O and H indicate similarities between groundwater and ephemeral streamflow, both linked to intensive daily rainfall.

Summary: Grasslands are important ecosystems supporting biodiversity and human livelihoods, but overgrazing has led to their degradation. This study examined the effects of grazing cessation on the temporal stability of plant community productivity in a desert steppe landscape. The results showed that grazing cessation increased the temporal stability of plant productivity, with species asynchrony and the temporal stability of shrubs/semi-shrubs being key drivers. Short-term grazing cessation had a greater impact on temporal stability than medium- or longer-term cessation.

Summary: Water footprint assessment is a method to identify the impacts and limitations of current systems, which helps us take suitable actions to improve water productivity and promote sustainable water use. This study provides a comprehensive evaluation of sector-wise water footprint in the Banas River Basin from 2008 to 2020, revealing an increase in water footprint due to population growth, industrial expansion, and crop demand. Measures should be implemented to improve water use efficiency in agriculture, which contributes to the majority of the basin's water footprint.

Summary: This study developed soil-suitability maps using machine learning algorithms and physico-chemical and phenological parameters, showing that phenological parameters had the greatest influence on soil-suitability prediction. The Receiver Operating Characteristics (ROC) curve validation demonstrated high accuracy for all models, with an AUC above 0.82, and the XgbTree model achieved the best performance with an AUC of 0.97. The findings highlight the excellent ability of machine learning models to predict soil-suitability.

Summary: Climate change, drought, erosion, water contamination resources, desertification, and loss of soil quality are major environmental risks worldwide. Conservation agriculture, especially no-till (NT) system, improves the physical quality of soil in both medium and long terms, making it suitable for the climatic and edaphic constraints of semi-arid areas in Morocco as well as in other parts of the world.

Summary: This study presents a long-term dual N and P input-output budget for the agriculturally rich Yakima River Basin, showing significant increases in N and P inputs to agricultural lands from 1945 to 2012, but no significant increases in riverine N and P export. This temporal disconnect between nutrient inputs and riverine exports highlights the need for further investigation of nutrient dynamics in semi-arid watersheds.

Summary: This study investigates the presence and distribution of microplastics (MPs) in agricultural soils in Iran. The results show that MPs are heterogeneously distributed in both surface and subsurface soils, with fibres being the most common shape. The study also reveals high erosion rates of MPs in agricultural soils, suggesting that these soils act as both a temporary sink and a dynamic secondary source of MPs.

Summary: The study found that while there are distinct and traceable pools of nitrogen in soil and bedrock, slow chemical weathering and landscape denudation limit the influence of rock-derived nitrogen. Atmospheric nitrogen deposition and nitrogen fixation dominate nitrogen inputs to the grassland ecosystem, despite the relatively large nitrogen pools in the saprolite and bedrock.

Summary: This study demonstrates the effectiveness of using remote sensing data to monitor agricultural activities in ASA regions and predict crop area and yield in advance. It also discusses the challenges associated with ensuring food security in ASA regions and recent advances in remote sensing technology that can be used for monitoring cropland and forecasting crop production and yield.

Summary: Healthy soils play a crucial role in planetary survivability, providing not only calories but also other essential functions. However, intensive agriculture is rapidly degrading soils and diminishing their capacity to deliver vital functions, highlighting the need to focus on the multiple functions of soils for long-term human welfare and the survivability of the planet.

Summary: Soil water repellency (SWR) can affect plant water use efficiency in rainfed cropping soils. Various factors such as drying method, incubation temperature, and specific surface area influence SWR response to soil water content. Maintaining consistency in drying methods and incubation temperatures is important to avoid methodological errors when studying SWR response to soil water content.

Summary: Factors affecting fertilizer decisions by grain growers are changing due to changing climatic conditions and volatility in global fertilizer and grain markets. Agronomic factors, especially rainfall, have the greatest influence on these decisions, while logistic factors become more important as farm size and fertilizer applications increase. Socioeconomic factors have become less influential over the years. Research and adoption activities should focus on agronomic and logistic issues for sustainable grain production.

Summary: Amelioration and management of large volumes of tailings resulting from alumina refining is a major challenge due to their high alkalinity and salinity. Blended byproduct caps, achieved by mixing tailings with other local byproducts, show potential as a cost-effective approach to reduce pH, salinity, and toxic elements. This study investigated the effects of blending alkaline bauxite residue with four byproducts on cap conditions, revealing that a combination of all four byproducts achieved the lowest pH and reduced concentration of toxic elements. Further improvements may be possible by adjusting addition rates, incorporating other materials, and extending leaching/weathering time.
