Creator:: Ou-yang, Ying
Abstract:: Gaseous transport through soil in the presence of soil microorganisms has been investigated. More recently, modeling of gaseous transport in the unsaturated zone has been investigated. However, the problem of mathematical model of oxygen and carbon dioxide transport through soil, as affected by the climatic conditions, the transport of soil...

Creator:: Kowsar, Ahang
Abstract:: 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...

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...

Creator:: McNabb, David H.
Abstract:: Forest soils with low bulk densities are often considered less susceptible to compaction than soils with higher bulk densities. The objective of this study was to determine if soil strength controlled the compression of soils with low bulk density. Four soils were selected for this evaluation. Three of these were...

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...
