Nitrogen uptake by wheat (Triticum aestivum VILL., Host) as a function of root temperature and plant water stress

Creator:

Sepaskhah, Ali Reza

Abstract:

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 moisture stress on S-urea mineralization and ryegrass yield

Creator:

Akratanakul, Wanee

Abstract:

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,...

Distinguishing biological and physical controls on soil respiration

Creator:

Phillips, Claire L.

Abstract:

Soil respiration, or the combined CO₂ emissions from roots and soil microorganisms, constitutes one of the largest losses of carbon (C) from terrestrial ecosystems. The major drivers of soil respiration, which include soil moisture, temperature, and substrate quality, have been known for some time. Nevertheless, correlations between these drivers and...
