Effects of soil moisture-tension on rubidium uptake by sunflowers

Creator:: Stevenson, David Stuart
Abstract:: There is considerable evidence that the growth and elongation of plant roots increases linearly or almost linearly with increasing water contents or decreasing moisture-tension of soil. If this is true it is difficult to distinguish the effects of different water contents on absorption phenomena such as water or ion uptake...

Full Text:: adventitious root systems. Rubidium uptake was not consistently affected by the different water contents

Continuum mechanics methods applied to root growth and the penetration of soil by roots

Creator:: McCoy, Edward L.
Abstract:: The principles of continuum mechanics provide a consistent framework for the derivation of mathematical statements describing transport of water and solute, and growth in plant tissue. These derivations are based upon the explicit consideration of the tissue as a mathematical continuum composed of a cell wall matrix, water, and solute...

An evaluation of soil warming for increased crop production

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...

Experimental analysis of subsurface heating and irrigation on the temperature and water content of soils

Creator:: Sepaskhah, Ali Reza
Abstract:: Multiple use of waste heat from power plants may become an important consideration in the development, siting, and certification of these plants. A multiple use system of components that can beneficially utilize waste heat may include home heating and cooling, greenhouses, animal enclosures, open basins for single cell protein production...

Effects of petroleum mulch on soil water content and soil temperature

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...

Dynamic mathematical model of oxygen and carbon dioxide exchange between soil and atmosphere

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...

Consolidation, compression, and shear strength of four western Oregon forest soils

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...

Germination and emergence of corn (Zea mays, L) as a function of soil physical parameters

Creator:: Sanchez, Ramon M.
Abstract:: Rates of germination and emergence of corn were measured as influenced by soil physical parameters using blotter paper and a sandy loam soil as growth media. The corn seeds used were a hybrid of Funk's (DJ7xLH93). Experimental conditions were soil temperature of 20°C, 25°C, 30°C, and 35°C, soil water potential...
