Assessment of Several Extractants for the Determination of Fe Availability to Corn (Zea mays L.) and its Critical Level in Some Calcareous Soils

open access: yesعلوم آب و خاک, 2021
Iron (Fe) is an essential micronutrient for plants and its deficiency occurs in calcareous soils. However, a suitable extractant for the estimation of plant-available Fe and its critical level in calcareous soils depends on the type of soil and plant ...

Genetically Engineered Nanobody–Recombinant Antibody Colloidal Gold Strip for Ultrasensitive Atrazine Detection in Fruits and Vegetables

open access: yesFood Safety and Health, EarlyView.
A sensitive colloidal gold immunochromatographic assay for atrazine was successfully established using genetically engineered nanobody‐recombinant antibody, which overcame the shortcomings of traditional antigen‐antibody. ABSTRACT Colloidal gold immunochromatography (CG‐ICA) is distinguished by its cost‐effectiveness and rapid detection capabilities ...

Selecting Promising Soil Quality Indicators for Monitoring Soil Management Effects Based on 10 European Long‐Term Field Experiments

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Soil quality can be measured through soil quality indicators that reflect soil processes. Aim: The aim of this study was to (1) identify a limited set of soil quality indicators that are most sensitive to agricultural soil management and that are widely applicable regardless of pedo‐climatic conditions, and (2) link common ...
