Abstract:
... Recent advances in molecular ecology have dramatically improved our knowledge of soil microbial diversity and offers new indicators of soil quality. The usefulness of diversity indices has never been greater as the astronomical amounts of data generated in the literature needs to be synthesized. Despite technical guidelines have been proposed to characterize soil microbiomes using high throughput ...

Abstract:
... Despite the potential of diversification strategies to achieve sustainability, diversified systems such as agroforestry are still not widely implemented by farmers, which indicates the need to further understand and adequately assess the impacts of diversification to inform the design of complex systems. In this paper, we conduct a systematic literature review focused on agroforestry coffee system ...

Abstract:
... This article outlines the importance of place-based policies derived from knowledge on local realities. Through an analysis of maize policies and their impact on the Zambezi region, Namibia, we illustrate the constraining limitations of insufficiently place-based policies. We highlight the problems of current top-down policies of production promotion, value chain integration, and sector protection ...

Abstract:
... Cropland plays an important role in Soil Organic Carbon (SOC) sequestration. Although the SOC stock and its dynamic in the past decades have been extensively investigated, the information as to where, how much, and how SOC could be potentially sequestered in the coming decades has rarely been available. Here, the Rothamsted Carbon model was applied to investigate the spatiotemporal pattern of SOC ...
... Despite the importance of reptiles in agroecosystems, little is known about the effects of agricultural intensification and pesticide use on these animals. We compared antioxidant and haematological biomarkers in the wild Italian wall lizards Podarcis siculus from three olive groves representing a gradient of management intensity. Lizards from the conventional grove showed induced antioxidant defe ...
... Estimation of spatial variability of soil organic carbon (SOC) content is important for agricultural management and environmental studies. In this study, geo-spatial prediction of SOC content was conducted to evaluate and compare geostatistical techniques of ordinary kriging (OK) and cokriging (CK) with hyperspectral satellite data (Hyperion) as an auxiliary variable. The study area located in wes ...

Abstract:
... Within the United States and Canada, the primary pollinator of alfalfa is the alfalfa leafcutting bee (ALCB), Megachile rotundata. Our previous findings showed that ALCB overwintering conditions impacted gene expression profile in bees that entered diapause early in the season. However, ALCB are a bivoltine species, leaving the question if bees exposed to summer temperatures and entering diapause ...

Abstract:
... A greenhouse is an agricultural management system that has shown the efficiency of food production. This system is an effective alternative to ensure maximum production results. Agriculture with greenhouse technology can create the desired environmental/climatic conditions. The rapid development of technology and science has led to the birth of communication between devices using IoT and AI. This ...

Abstract:
... Soil heavy metal distribution maps can provide decision-making information for pollution control and agricultural management. However, the estimation of heavy metals is sensitive to the resolution of the soil spectra due to their sparse content in soils. The purposes of this study were to test the sensitivity of Ni, Zn and Pb prediction results to variations in spectral resolution, then to map the ...
... Lime and phosphorus (P) applications are common agricultural management practices. Our aim was to quantify the effects of long‐term application practices on root growth and abundance of arbuscular mycorrhizal fungi (AMF) under field conditions. We assessed the effects of lime and P fertilizer applications on barley yield, root growth and AMF abundance in 2016. Treatments were no, low, medium and h ...

Abstract:
... Detailed soil maps contribute to the understanding of agricultural and food value chains. PlanetScope satellite constellations have high spatial and temporal resolution and could be used to develop Synthetic Soil Image (SYSI) at specific dates of field crops calendar. This work aimed to derive a SYSI from PlanetScope time series and estimate soil clay content, an important attribute related to sev ...
... Biofertilizers are substances that promote plant growth through the efficacy of living microorganisms. The functional microbes comprising biofertilizers are effective mediators in plant-soil systems in the regulation of nitrogen cycling, especially in nitrification repression. However, the deterministic or stochastic distribution of the functional hotspot where microbes are active immediately afte ...

Abstract:
... Management of agricultural soil quality requires fast and cost-efficient methods to identify multiple stressors that can affect soil organisms and associated ecological processes. Here, we propose to use soil protists which have a great yet poorly explored potential for bioindication. They are ubiquitous, highly diverse, and respond to various stresses to agricultural soils caused by frequent mana ...

Abstract:
... Digital soil mapping (DSM) aims to produce detailed maps of soil properties or soil classes to improve agricultural management and soil quality assessment. Optimized sampling design can reduce the substantial costs and efforts associated with sampling, profile description, and laboratory analysis. The purpose of this study was to compare common sampling designs for DSM, including grid sampling (GS ...

Abstract:
... Against the background of fundamentally changing political and social requirements of agricultural production, the requirement profile of farmers has changed. The future of agriculture is widely discussed. To prepare a ground for future debates and policy programme design, it is essential to obtain an understanding of which values underlie the behaviour of farmers. This paper applies Schwartz's va ...

Abstract:
... The nonexistence of universal drought indicators may lead to uncertainties in the variability of drought, leading to discrepancies in the frequency change in compound dry and hot events (CDHEs) in different regions across the globe. Understanding the impact of the selection of drought indicators on the variability of CDHEs is important for assessing their risks and pursuing mitigation measures. Ho ...

Abstract:
... Agricultural management is essential to enhance soil ecosystem service function through optimizing soil physical conditions and improving nutrient supply, which is predominantly regulated by soil microorganisms. Several studies have focused on soil biodiversity and function in tea plantation systems. However, the effects of different agriculture managements on soil fertility and microbes remain po ...
... Bat populations are threatened in many regions of the world, partly due to the loss of foraging and commuting habitats in farmland and declines in insect prey populations caused by agricultural intensification. Given that bats play an important role as bioindicators and in suppressing crop pests, it is crucial to mitigate negative impacts that arise from these threats. In this study we evaluated t ...

Abstract:
... Agricultural irrigation is an important vehicle for increasing crop yield, but large-scale irrigation has posed great challenges to global and regional water availability and climate change via altering land-atmosphere interactions. The knowledge of irrigation distribution is essential to understand regional water cycles and guide agricultural management decision-making, but such information is sc ...

Abstract:
... Fertilization management and crop growth can affect soil water repellency (SWR) through altering other soil properties such as micro-aggregate, soil organic carbon (SOC) and total nitrogen (TN). However, the extents and magnitudes of these effects remain unclear. This study aimed to determine the effects of different crop growth periods and long-term fertilization managements on SWR and selected s ...
