Nutrient Cycling Index in Relation to Organic Matter and Soil Respiration of Rehabilitated Mine Sites in Kelian, East Kalimantan [PDF]

Journal of Tropical Soils, 2011
Degraded soils at mine sites are often associated with decreased soil fertility. However, soil nutrient status might be improved through biomass recovery primarily from re-vegetation.

Relations between soil respiration, humus quali­ty and ca­tion exchange capacity in selected subtypes of chernozem in South Moravia region

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Soil organic matter (SOM) undergoes short and long-term transformation in the soil. Microorganisms through their enzymes are able to mineralize organic carbon while the rate of this process is different. Biological test though referred to one of the main

Global ecological predictors of the soil priming effect. [PDF]

, 2019
Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, biotic communities, and soil ...

Earthworms accelerate rice straw decomposition and maintenance of soil organic carbon dynamics in rice agroecosystems [PDF]

PeerJ, 2020
Background To promote straw degradation, we inoculated returned farmland straw with earthworms (Pheretima guillelmi). Increasing the number of earthworms may generally alter soil organic carbon (SOC) dynamics and the biological activity of agricultural ...

Assessment of the Health of Soils Contaminated with Ag, Bi, Tl, and Te by the Intensity of Microbiological Activity

Life, 2023
Soil health is the basis of ecological and food security for humanity. Among the informative indicators of soil health are microbiological indicators based on the intensity of the carbon dioxide release from the soil.

Application of compost in spruce forests: effects on soil respiration, basal respiration and microbial biomass

Forest Ecology and Management, 2002
Compost from separated organic household waste contains considerable amount of nutrients such as N, P, K, Mg and Ca and may be used for amelioration of degraded forest soils. Our objective was to assess the effect of compost application on soil respiration, soil basal respiration and soil microbial biomass of two mature Norway spruce plantations in ...

Denitrification and availability of carbon and nitrogen in a well-drained pasture soil amended with particulate organic carbon [PDF]

, 2011
A well-drained soil in N-fertilized dairy pasture was amended with particulate organic carbon (POC), either sawdust or coarse woody mulch, and sampled every 4 wk for a year to test the hypothesis that the addition of POC would increase denitrification ...

The biochar effect on soil respiration and nitrification

Plant, Soil and Environment, 2018
Soil microorganisms play a main role in the nutrient cycle and they also play an important role in soil health. This article studies the influence of three rates of biochar (0.5, 1 and 3%) in comparison with control (0 biochar) in two different soils ...

Can combined compost and biochar application improve the quality of a highly weathered coastal savanna soil?

Heliyon, 2021
Soil fertility decline is a major constraint to crop production in sub-Saharan Africa. The positive effect of biochar and compost applications on soil fertility has been reported by many authors.
