Soil Health Check-Up of Conservation Agriculture Farming Systems in Brazil

Agronomy, 2021
Conservation agriculture has been promoted as the main strategy to regenerate soil life but its effect on soil enzyme activity remains little documented. This study investigated the β-glucosidase and arylsulfatase enzymes as tools to evaluate soil health

The relationship between soil properties, enzyme activity and land use

Leśne Prace Badawcze, 2017
The aim of this study was to assess the effects of different types of land use (forest, tillage and pasture) on soil properties, especially enzyme activity. Our investigation was carried out on 53 research plots with 11 plots in broadleaved forest stands,

Effects of metribuzin on the activity of some enzymes in soil

Pesticidi i fitomedicina, 2008
Effects of metribuzin on the activity of some enzymes in soil was investigated. Trials were set up in the laboratory on a clay loam soil. Metribuzin was applied at 12.0, 24.0 and 60.0 mg/kg soil rates and soil samples were collected 3, 7, 15, 30 and 45 days after metribuzin treatment for analyses.

Soil-specific enzyme activity provides novel insight into the soil microbial necromass accumulation during sand dune fixation

Frontiers in Microbiology
IntroductionSoil enzymes are critical to plant growth and soil carbon turnover. However, the traditional method of assessing enzyme activity per unit of soil may be insufficient; instead, soil-specific enzyme activity per unit of soil organic carbon ...

Localization of C Cycle Enzymes in Arable and Forest Phaeozems within Levels of Soil Microstructure

Microorganisms, 2023
Soil microbial and enzyme activities are closely related to the spatial variability of soil environmental conditions at the microscale (μm-mm). The origin and localization of the enzymes are somewhat neglected when the measured activity is used to ...

Enzyme activities in Cerrado soils of Brazil [PDF]

Communications in Soil Science and Plant Analysis, 1999
Abstract Enzymes play an important role in cycling of organically bound nutrients in soils. Pyrophosphatase (PPi), acid phosphatase (AP), arylsulfatase (AS), urease (UR), and dehydrogenase (DH) activities were measured in air‐dry samples from the top 15 cm of two dark red Latosols and four red‐yellow Latosols from Cerrado regions of Minas Gerais (MG ...
