Summary: Increasing nitrogen use efficiency in rice intensification (SRI) is crucial for achieving high crop yield and reducing nitrogen losses. This study aimed to determine the optimal leaf color chart (LCC) value for real-time nitrogen application in rice varieties under SRI. The results showed that an LCC value of 5 with 30 kg N/ha produced the highest grain yield and was effective in increasing nitrogen use efficiency and yield in rice. Additionally, using an LCC value of 5 with 20 kg N/ha also maintained high agronomic and recovery efficiency of nitrogen.

Summary: Crop-specific, high-resolution phosphorus rate information is crucial for sustainable agricultural fertilizer management in China. The current phosphorus fertilizer dataset based on coarse national statistics lacks accuracy and crop-specific information. This study utilized provincial and county-level data to generate detailed maps of phosphorus rate for rice, wheat, and maize from 2004 to 2016 (CN-P). CN-P provides improved spatial heterogeneity and more accurate estimates of phosphorus rate for each crop compared to the existing dataset. The CN-P dataset has great potential for modeling sustainable agricultural fertilizer management strategies and addressing phosphorus pollution.

Summary: This study investigates the effects of different forms of nitrogen fertilizer on the reduction and dissolution of arsenic-bearing iron minerals and microbial-mediated arsenic transformation processes. The results show that nitrate nitrogen fertilizer reduces the bio-availability of arsenic in soil, while ammonium nitrogen fertilizer promotes the release of arsenic into porewater. However, the combined application of nitrate and ammonium nitrogen has no significant effect on arsenic concentration in rice grain and its transformation in paddy soils. These findings provide insights into the rational use of nitrogen fertilizers to reduce the risk of arsenic contamination in rice.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: This study investigated changes in vascular plant species in Central European arable fields and their edges from 1930 to 2019. The results showed a small decline in overall species occupancy, but a more pronounced species turnover. Species with environmental preferences for nutrient-rich sites with neutral pH increased in occupancy, while species typical for arable fields decreased. No response to climate change was observed, and there was a decrease in archaeophytes and native species and an increase in neophytes.

Summary: Proper bed substrate selection is crucial for the performance of constructed wetlands, especially when treating drainage water with high nitrogen and low carbon and phosphorus concentrations. In a field-scale pilot plant, adding a carbon-rich substrate such as soil or biochar increased phosphorus availability in beds. Beds with soil displayed higher microbial density and activity, as well as better plant growth compared to gravel. These findings highlight the importance of selecting suitable substrates for treating irrigated agricultural water.

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: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
