Summary: The degradation of soil, vegetation and socio-economic transformations pose a significant threat to land production in Africa. This study assesses soil and land productivity, and finds that high land productivity is attributed to factors such as soil quality, land management, land policy reforms, and favorable climatic conditions. The study also determines the influence of rainfall on standing biomass.

Summary: In this study, different machine learning models (Cu, RF, SVM, GPR) were used to predict soil phosphorous sorption parameters (PSPs). The results showed that using topographic attributes alone was not sufficient for accurate prediction of PSPs, but combining remote sensing data with soil properties reliably predicted PSPs. The RF model had the lowest RMSE values for MBC, the SVM model for PBC, the Cubist model for SPR, and the RF model for SBC. The study concluded that remote sensing data was an easily obtainable dataset that could reliably predict PSPs in the study area.

Summary: This study in Ghana's northern savanna region aimed to improve soybean yield and profitability through input integration. Results showed that the high input system (T7) had the highest grain yield and rain use efficiency, while the low input system (T2) had the highest marginal net benefits and marginal rate of returns. This suggests that smallholder farmers prefer the low input system (T2) with the least production cost and the highest marginal net benefit and marginal rate of returns.

Summary: The study assessed soil fertility status in peri-urban counties of Nairobi for Capsicum production, generating a soil fertility map and developing a fertilizer program. Variations in soil nutrients across counties were identified, with recommendations for addressing deficiencies in nitrogen, organic carbon, and phosphorus. The fertility index was rated as medium with most nutrients optimal, except for nitrogen and organic carbon, leading to the creation of a fertilizer program to aid farmers in planning schedules for Capsicum production.

Summary: Thinning in even-aged forest management has been shown to increase concentrations of soil nitrate, total P, and available P, without affecting soil total N and ammonium. Thinning stimulates soil microbial activities, enhances N and P cycling, and varies in its effects depending on climates and forest biomes. Overall, thinning promotes forest soil N and P cycling, contributing to improved soil fertility.

Summary: Small amounts of gas can be found in almost every sediment in marine or coastal environments. Previous studies have shown that gas can negatively affect the mechanical properties of soil, particularly in tide affected areas where geohazard occurrence and dike safety are a concern. However, the impact of a homogeneous distribution of gas bubbles in soil on its mechanical properties remains poorly understood. In order to further investigate the shear strength of gassy soils, an experimental setup and sample preparation procedure using the axis-translation method were developed.

Summary: Biochar can be beneficial for soil fertility and crop yields, but its effects depend on its properties and pedoclimatic conditions. In a field experiment, wood gasification biochar had no significant effect on soil physicochemical properties, enzyme activities, and wheat grain yield. However, it can contribute to soil carbon stock without adversely affecting crop yield, making it a potential solution for recycling waste woody materials.

Summary: Monitoring phosphorus availability in soil can help identify deficiencies in crops and improve nutrient management. The relationship between soil test P and cumulative P removal in long-term studies was analyzed, leading to the development of a predictive model for assessing STP decrease. The model offers insights for optimizing crop yield and nutrient management practices.

Summary: The study found that climate change will have varying effects on maize and soybean yields, with maize yields declining more due to increased temperatures shortening the crop cycle, while soybean yields are more limited by water stress. Soybean showed a more pronounced response to CO2 levels compared to maize. Soil degradation exacerbated the negative effects of global warming on crop yields.

Summary: The study analyzed the relationships between nutrient uptake per unit grain yield and its components for N and S in malting barley. Results showed that grain N concentration tended to increase threefold while S concentration doubled as nutrient uptake per unit grain yield increased. Nutrient harvest index had a negative association with nutrient uptake per unit grain yield, with a steeper decrease in S harvest index compared to N harvest index.

Summary: Comparing different winter legume species based on plant traits showed that root biomass and biological nitrogen fixation are more important than shoot biomass for selecting service crops. Trifolium pratense and T. alexandrinum were top-ranked for having the largest amount of root biomass and BNF. Therefore, selecting service crop species should consider not only shoot biomass but also other plant traits like root biomass and BNF.

Summary: The most widely used fertilizer nitrogen recommendations for maize in Argentina are based on the relationship between grain yield and available nitrogen. This study found that combining factors related to crop demand and soil supply can improve fertilizer recommendations. Soil texture and yield environment were both found to impact nitrogen response, highlighting the importance of considering these factors for sustainable agriculture.

Summary: This study finds that the contribution of belowground structures to the nitrogen balance and seed nitrogen in soybean is often overlooked. Through field experiments, it is discovered that the nitrogen derived from biological nitrogen fixation in belowground components can change the results of nitrogen balances. It is also found that biological nitrogen fixation is the main source of seed nitrogen, which remains important under different growing conditions.

Summary: There is a complex relationship between land degradation, water efficiency, and crop yield in arid and semiarid regions. This study focused on the Semiarid Pampa region in Argentina, where land use changes have led to soil quality decline and endangered agricultural activities. The use of polyacrylamide (PAM) as an option for increasing productivity and protecting soil resources was examined, with particular emphasis on its impact on water storage and aggregate stability mechanisms in this fragile land. The results showed that incorporating superabsorbent PAM had a significantly positive effect on hydrophysical variables and plant biomass. It improved water retention at lower suctions, increased aggregate stability, and enhanced soil cohesion. Overall, superabsorbent PAM has the potential to maintain crop yields and improve soil quality.
