Summary: Understanding the spatial-temporal variability of soil enzymatic activity and its relationship with nitrogen resources and crop yield is crucial for rational management practices. This study revealed spatial and temporal variability in soil parameters, with higher values observed in July. The southern part of the field exhibited considerable enzyme activity and high N-NO3 application, indicating separate production zones and higher crop yield. There was a negative interaction between N-NH4 and N-NO3 and urease in the soil. The findings emphasize the importance of enzymatic and chemical parameters in soil for crop yield and lay the foundations for precision agriculture.

Summary: This paper comprehensively analyzed the soil characteristics and fertility of cultivated land in Xuwen County using geostatistics, geographic information system (GIS), and fuzzy mathematics. The results showed that the overall level of soil fertility in Xuwen County is above average, with a trend of high fertility in the South and low fertility in the North. These findings provide theoretical guidance for improving fertilizer utilization, fine management of cultivated land, and ecological environment.

Summary: This study analyzed the spatial distribution and influencing factors of soil nutrients in the semiarid Anding district farming region in northern China. The results showed considerable variability in soil nutrient content, with soil organic matter, total nitrogen, and available phosphorus showing increasing trends from the middle to the northeast and southwest, while available potassium showed the opposite trend. Factors such as soil texture, irrigation method, and water source type significantly influenced the distribution of soil nutrients.

Summary: In addition to water scarcity, the sustainable development of agriculture in arid and semi-arid regions of China is also constrained by soil salinization. This study aimed to investigate the spatial distribution and variability of soil salinity in drip-irrigated cotton fields under different irrigation levels in northwest China. The results showed that irrigation amount significantly influenced the distribution of soil salinity, with increased irrigation reducing total dissolved solids (TDS) in the soil but increasing the area of the desalination zone and the depth of salt accumulation. The variability of soil salinity was affected by irrigation amount, growth stage, and soil depth, with the largest spatial variability occurring in the middle growth stage of cotton.

Summary: Effective nitrogen management practices are crucial for sustaining crop production and minimizing nitrate leaching loss in irrigated fields. However, limited studies have been conducted on the applied practices. Two field studies were conducted in the Columbia Basin to evaluate the performance of various nitrogen fertilizers in spring and winter wheat. The results indicate that fertilizer treatments did not significantly affect wheat grain yield and protein content, but the application methods and rates had some impact on soil nitrogen content.

Summary: In this study, the spatial heterogeneity and influencing factors of soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) in surface soil of coastal protected forests in northern China were analyzed. The results showed significant changes in SOC, TN and TP content under different protected forest types and strong spatial dependence. Furthermore, using vegetation and terrain factors as covariates improved the accuracy of soil C-N-P spatial distribution prediction.

Summary: The spatial structures of natural variables are often complex and exhibit non-Gaussian spatial dependence. Existing approaches to consider non-Gaussian behavior are limited. This study presents a flexible method for defining non-Gaussian spatial dependence, based on continuous deformation of fields with different Gaussian spatial dependence. The methodology is illustrated with theoretical examples and demonstrated in a real-life example of groundwater quality parameters.

Summary: This study investigated the effects of ridge tillage and plastic film or straw mulching on yield stability, soil water storage, nitrogen budget, and soil nitrogen and organic carbon contents in rain-fed spring maize on the Loess Plateau. The results showed that plastic film mulching increased maize yield and stability, improved water use efficiency, and maintained soil nitrogen and organic carbon contents. However, the potential impact of microplastic contamination should be considered.

Summary: The study demonstrates that zeolite and potassium applications, whether used alone or in combination, significantly increase rice grain yield and economic benefits. The recommended treatment of 5 t ha(-1) zeolite with 30 kg ha(-1) potassium fertilizer showed the highest increase in grain yield and economic benefits compared to commonly used practices. This indicates that the use of zeolite and potassium together can improve productivity and profitability in paddy cultivation.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.
