Microbial activity and metabolic quotient of microbes in soils amended with biochar and contaminated with atrazine and paraquat

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
The study was conducted to determine how biochar as a soil amendment maintained the microbial community in pesticide contaminated soils. Alfisol (Adenta series – Typic Kandiustalf) and Vertisol (Akuse series – Typic Calciustert) were amended with biochar

Effect of forestry practices on the biological characteristics of soils (Case study: Beech Forest of Asalem) [PDF]

مدل‌سازی و مدیریت آب و خاک, 2022
Introduction In forest management, it is essential to maintain soil performance. Forest soils control and support many forest ecosystem services and tree growth. So, maintaining soil health is critical to sustainable forest management.

Film Mulching with Low Phosphorus Application Improves Soil Organic Carbon and Its Decomposability in a Semiarid Agroecosystem

Agriculture, 2022
Soil organic carbon (SOC) storage and decomposability are crucial for soil quality. Film mulching and phosphorus (P) application are important agricultural practices on the semiarid Loess Plateau. This study analyzed the combined effects of film mulching

Leaf litter identity rather than diversity shapes microbial functions and microarthropod abundance in tropical montane rainforests

Ecology and Evolution, 2021
In tropical forest ecosystems leaf litter from a large variety of species enters the decomposer system, however, the impact of leaf litter diversity on the abundance and activity of soil organisms during decomposition is little known. We investigated the

Lipid Oxidation Assessed by Indirect Calorimetry Predicts Metabolic Syndrome and Type 2 Diabetes

Frontiers in Endocrinology, 2019
Purpose: Diabetes has been linked to an impaired ability to oxidize fatty acids. Fat oxidation can be assessed clinically by a respiratory quotient measurement during fasting.

Soil microbial metabolism and invertase activity under crop rotation and no-tillage in North China

Plant, Soil and Environment, 2013
Soil samples were collected at both jointing and maturing stages of maize and wheat to compare the effects of 4-year no-tillage (NT) and conventional tillage (CT) on seasonal variations of microbial biomass carbon (C), metabolic quotient, and invertase ...

Tree stratum alteration decreases C use efficiency and the stability of litter decomposition in a sacred fir (Abies religiosa) forest

Botan‪ical Sciences, 2022
Background: There is limited information to predict the direction in which canopy modification affects the microbial carbon use efficiency (CUE) and, consequently, the magnitude and stability of litter decomposition in monodominant sacred fir (Abies ...
