Forest soil respiration is the sum of heterotrophic (microbes, soil fauna) and autotrophic
(root) respiration. The contribution of each group needs to be understood to evaluate …

This review deals with methodological approaches, measured rates, and environmental
control of two major interdependent processes regulating the structure and function of …

An existing model of C and N dynamics in soils was supplemented with a plant growth
submodel and cropping practice routines (fertilization, irrigation, tillage, crop rotation, and …

Respiration is a large and important component of the carbon economy of crops. There are
already several good books dealing with the biochemistry and physiol ogy of plant …

A significant portion of the carbohydrates that are produced daily in photosynthesis are
respired in the roots. The magnitude varies with age of the plants, growth conditions, and the …

Core Ideas Movement of O2 in the soil is mainly diffusive. Respiration consists of plant root
and microbial O2 uptake, roughly of the same magnitude. Reduced O2 and elevated CO2 …

Normalized difference vegetation indices derived from radiances measured by the
Advanced Very High Resolution Radiometer aboard the NOAA 7 polar‐orbiting satellite …

Soil‐surface CO2 flux (Fs) is an important component in prairie C budgets. Although grazing
is common in grasslands, its effects on Fs have not been well documented. Three clipping …

Net photosynthesis (PN), root respiration (RR), and regrowth of Bouteloua gracilis (HBK)
Lag. were examined in the laboratory over a 10-day period following clipping to a 4-cm …
