Summary: Analyzing free enzyme activity in pore-water samples is a reliable method for understanding biological activity in soils, showing a high correlation with enzymatic activities measured directly from soil samples. This approach offers a simple, non-destructive, and continuous way to assess biogeochemical dynamics under changing environmental conditions. Preliminary implementation in a contaminated site also demonstrated a strong correlation between in-situ enzyme activity measurement and pollutant biodegradation rate in the soil.

Summary: This experiment showed that different biochar amendments can affect soil microbial activities differently, with Lantana camara biochar having the highest microbial biomass carbon. Biochar application also increased dehydrogenase activity and acid phosphatase, with the highest alkaline phosphatase in maize stalk biochar. The study suggested that biochar application at lower concentrations may enhance biological indicators more effectively than higher concentrations.

Summary: Agricultural soil quality has been extensively discussed in recent decades. This study focused on three olive grove areas in Portugal with different management techniques, aiming to assess the influence of these techniques on soil quality. The results showed that the concentrations of organic carbon and total nitrogen were highest in the intensive olive grove in Lisbon, while Ca, Mg, Na, and K were the main differences between Lisbon and the other two groves in Santarem. Enzymatic activities were found to be related to various soil concentrations. Soil management and agricultural practices were identified as determining factors for enzymatic activities in the olive groves.

Summary: The relationship between soil quality index (SQI(FERTBIO)) and soil functions with relative cumulative grain yields (RCY) and soil organic carbon (SOC) was evaluated in tropical clayey Cerrado Oxisol. The study found that phosphorus fertilization resulted in higher crop yields and better soil quality, and established critical limits using linear regression analysis to interpret the individual scores of the SQI and soil functions based on RCY and SOC.

Summary: Enzyme activity is important for soil biochemical processes and nutrient cycling. This study investigated the effects of long-term changes in nitrogen and water on two types of soil enzymes, beta-1,4-glucosidase and acid phosphatase. The results showed that nitrogen addition inhibited both enzymes, while water addition decreased the activity of acid phosphatase. The effects of nitrogen and water on enzyme activity were mainly mediated by changes in soil microbial biomass carbon.

Summary: The synergistic effect of using nanochitosan to deliver Pseudomonas fluorescens on its stability in the soil and induction resistance against fusarium wilt in tomato plants was investigated. The results showed that the nano-Pf treatment resulted in the highest growth and disease reduction percentage. Additionally, the treatment enhanced the defense enzyme activity in tomato plants and effectively mitigated Fusarium wilt infection.

Summary: Soil quality indicators are important tools for evaluating the ecological functions of soil. This study used the SMAF model to assess the soil quality under different nutrient management strategies in a rice-wheat cropping system. The results showed that the conjunctive application of NPK with manures improved the overall soil quality to a greater extent than other management practices.

Summary: The study found that the soil carbon and nitrogen stocks increased in silvopastoral systems, but were still lower than those in native vegetation. The quality of soil organic matter was protected in the most stable soil organic matter fractions. The soil microbial carbon increased during the rainy season, while the metabolic quotient increased during the dry period.

Summary: The study evaluated the impact of light availability and post emergence herbicide application on Cyperus rotundus management. Results showed that doses greater than 70.30 g ha(-1) of halosulfuron methyl effectively controlled C. rotundus, regardless of light availability. Additionally, C. rotundus was managed faster under full sunlight, and efficiency of photosystem and starch accumulation decreased with increasing herbicide doses.

Summary: This study aimed to identify the global risk of invasion and establishment of the sweet potato pest Bedellia somnulentella and develop preventive policies. The study found that climate change could reduce the pest's suitable areas but increase them in temperate regions. The survey only considered weather data and did not include other factors. The findings are helpful for policy development and pest management strategies.

Summary: This study evaluated the acute and chronic toxicity of neem oil on the endoparasitoid P. elaeisis. The results showed that the neem LC50 for P. elaeisis was lower than the recommended concentration for pest control, indicating high acute toxicity. However, the sublethal effects were low. It is important to carefully control the concentration of neem oil in integrated pest management programs to avoid interference with the natural enemy P. elaeisis.

Summary: This study analyzed the biotic and abiotic factors that influence the initial growth and adaptation of two Eucalyptus genotypes (Eucalyptus cloeziana and Eucalyptus urograndis) intercropped with Sorghum bicolor and Urochloa brizantha in Agrosilvopastoral (ASP) systems in the Brazilian Cerrado. The results showed that bees and termites were the main biotic factors causing damage and weakness in the Eucalyptus cloeziana and Eucalyptus urograndis genotypes, respectively. Eucalyptus urograndis performed better in terms of total height and diameter at breast height, and was more tolerant to water stress. Therefore, it is recommended for use in ASP systems in sites with high temperature and irregular rainfall distribution.

Summary: The Century model was used to evaluate the long-term soil organic carbon (SOC) accumulation capacity and the effects of management and climate change on integrated crop livestock-forest (ICLF) systems. The results showed that the model reliably simulated SOC stocks and predicted an increase in SOC stocks by converting degraded pastures into agrosilvopastoral systems, especially in clayey soils. Agroforestry systems are potentially viable to maintain the sustainability of agriculture in the face of climate change.

Summary: The objective of this study was to assess the impact of filter cake biochar on the chemical and microbiological properties of a dystrophic red-yellow latosol cultivated with macauba, araca, and cajuzinho do cerrado, species native to the Cerrado. After 120 days of transplanting the seedlings, the responses of soil attributes to four doses of biochar (1%, 2%, 4%, and 8% v/v) and two control treatments were evaluated. The results showed that the 1% dose of biochar and mineral fertilization were the most effective treatments in improving soil conditions and enhancing the chemical and microbiological attributes of the soil.

Summary: In this study, the flora composition and vegetation profile of two veredas in the Cerrado region of Brazil were evaluated. The results showed that the veredas were floristically different in terms of species composition, richness, and diversity. The study also found that anthropogenic factors have led to changes in the species composition of the veredas, resulting in drought and the collapse of these formations.

Summary: This study investigated the changes in soil physical attributes and carbon stock in soil organic matter fractions in irrigated sugarcane crops in the North of Minas Gerais State, Brazil, in response to different management practices over time. The results indicated that maintaining a portion of straw on the soil surface contributes to preserving soil structure and stable fractions of organic carbon, while soil tillage for sugarcane field renewal significantly reduces total soil organic carbon in regions with high temperatures and in irrigated systems.
