Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...
A special apparatus was developed in which the soil moisture
levels of several soil cells could be maintained independently by
various osmotic solutions at a selected temperature. The effect of
four soil moisture suctions and four soil temperatures on the rates
of transpiration, photosynthesis and respiration of monterey pine
seedlings...
There is a growing consensus that anthropogenic warming will impact soil organic matter (SOM). Globally, soil contains 2-3 times more carbon (C) than plants, and like plants, temperature induced change of SOM could have significant climate repercussions. Although, the majority of warming experiments have increased day and night temperatures equally,...
Petroleum mulch applied on the soil surface over a row of
planted seeds promotes a more rapid and a more uniform germination
of seeds, enhances elongation of seedlings and in some cases increases
the yield of the crop. The beneficial effects of petroleum
mulch have usually been attributed to increased...
A growth chamber experiment was conducted to determine the
rate of S-urea mineralization and effect of S-urea on the yield of
ryegrass (Lolium multiflorum) grown in Steiwer soil as influenced
by soil temperature (60, 75, and 90° F) and soil moisture stress
(0. 10, 0.35, and 2.50 bars). Plant yield,...
The effect of soil temperature and plant water stress on nitrogen
uptake, growth rate and transpiration rate of wheat (Triticum aestivum
VILL. , Host) seedlings was studied. A special apparatus for the control
of plant water stress and root temperature was used.
Leaf area was measured by the air flow...
The effect of soil temperature and soil water suction on the rate
of phosphorus uptake and growth rate of wheat (Triticum aestivum
VILL. ,
Host) was studied.
Plants were grown in perlite slabs
separated from an osmotic solution by a semi-permeable membrane.
Measurements were made at temperatures of 10.0, 18.3,...
The effects of aspect, canopy, elevation, and season both singly
and in combination on soil temperatures at 50 cm depths were
evaluated.
The objectives of the study were (i) to develop a standard procedure
for obtaining soil temperature data adequate to classify soils
at the family and great group levels,...
