Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

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

Journal 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 ...

INFLUENCE OF FERTILIZATION AND HERBICIDES APPLICATION ON SOIL MICROFLORA AND ELEMENTS OF SUGAR BEET YIELD [PDF]

Poljoprivreda, 2004
Two-year sugar beet trials were set up on two localities: Đakovo (Stagnic Luvisol) and Osijek (Dystric Cambisol). The soils showed acid environment respond (pHKCL 4.9 – 5.4) and low humus contents (1.3 – 1.6%).

Influence of Ash Applied to Oat Crop (Avena sativa L.) Grown under Organic Fertilization with Manure

Scientific Papers Animal Science and Biotechnologies, 2023
The power plant ash is an inorganic residue with a variable chemical buildup according to the type of charcoal used and quality. Depositing, stabilizing and eventually reintegrating the ash in the natural circuit raises a series of problems due to its ...

Yield‐Dependent Allocation Functions Overestimate Root‐Derived Carbon Inputs in Wheat and Maize

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Root‐derived carbon (C) inputs for wheat and maize were estimated using the yield‐based allocation functions of Bolinder et al. and Jacobs et al. Comparison with measured root C showed systematic overestimation that becomes larger as predicted C increases.

Manure fertilization for soil organic matter maintenance and its effects upon crops and the environment, evaluated in a long-term trial [PDF]

, 2001
The effects upon soil organic matter and crop yield of applying farmyard manure, both with and without biodynamic preparations, as compared to treatments receiving mineral fertilizer (and straw) have been studied in a field trial starting in 1980.
