MICROBIAL ACTIVITY CHANGES IN SOIL AMENDED WITH RAW AND COMPOSTED SEWAGE SLUDGE [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2003
The changing of soil biological characteristics due to the addition of raw and composted sewage sludge (at 0, 1.5 and 3.0%) were evaluated during a 165-day incubation experiment. Generally, increasing the addition rate of sewage sludge and its compost up

Soil respiration across a permafrost transition zone: spatial structure and environmental correlates [PDF]

open access: yesBiogeosciences, 2017
Soil respiration is a key ecosystem function whereby shifts in respiration rates can shift systems from carbon sinks to sources. Soil respiration in permafrost-associated systems is particularly important given climate change driven permafrost thaw ...

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

open access: yesActa 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

TISSUE RESPIRATION, GROWTH, AND BASAL METABOLISM

open access: yesThe Biological Bulletin, 1953
1. The relation between tissue respiration and body size was investigated in the rat. Determinations of Qo2 were made on heart, lung, liver, kidney cortex, brain cortex, diaphragm, and thymus of animals ranging from 9 gm. to 392 gm. body weight, including some determinations on fetuses and fetal tissues. A statistical evaluation of ca.

The biochar effect on soil respiration and nitrification

open access: yesPlant, 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 ...
