Abstract:
... The comparative effects of reacted and unreacted CaCO₃ in two acid soils on the growth and nutrient uptake of alfalfa and sunflowers were determined. The soils, both Mardin silt loams, had pH values of 4.6 and 5.5 respectively, and CaCO₃ was applied at the rate of 1.35 tons per 2 × 10⁶ lbs. Reaction of CaCO₃ with the more acid soil increased the yields and calcium contents of both alfalfa and sunf ...

Abstract:
... Permanent-wilting percentage, 15-atm. moisture percentage, and hygroscopic coefficient frequently have been used as indirect measures of the lower limit of readily available moisture for soils in situ. These three methods were evaluated by comparison with a field method for determining the lower limit of moisture readily available to sunflowers growing in Dickinson sandy loam, Wabash silt loam, an ...

Abstract:
... Sawdust and other wood wastes applied to soil may retard plant growth by inducing nitrogen deficiency but these effects with Douglas-fir are less pronounced than with many other residues of wide C:N ratio. While Douglas-fir wood is extremely low in nitrogen it is low also in available carbon. The predominating lignin-cellulose complex is resistant and only slowly metabolized, enabling a minimum am ...

Two moisture levels, 20-cm. water tension and moisture content at “flex point,” were imposed on the 20 separates. Nutrient solution was applied to the separates. Noticeably different growth rates of sunflowers were measured ...

Abstract:
... SynopsisShoot growth was critically damaged when soil containers were placed in nitrogen at early stages of growth before roots became well established. Root growth essentially ceased when placed in the nitrogen atmosphere and there was a time lag in recovery when placed in a “normal” atmosphere. All species studied, cotton, sunflower, and green beans, showed similar results. ...

Abstract:
... SynopsisOxygen diffusion rates increased 1.8% per degree centigrade rise in soil temperature for a given surface oxygen concentration. When diffusion rates are low, higher soil or aerial temperatures are more detrimental to shoot growth than lower temperatures. Regardless of temperature, roots did not grow when oxygen diffusion rates were less than 20 ✕ 10⁻⁸ g. cm.⁻² min.⁻¹. A higher diffusion rat ...

Abstract:
... SynopsisRoot growth was not dependent upon the water content of a sandy loam, but was markedly increased by increased initial water contents in a clay loam. The relationship was slightly curvilinear. Root growth as a result of water content or soil moisture suction treatments should be accounted for whenever the effects of water supply on absorption processes are under investigation. A technique i ...

Abstract:
... SynopsisWater losses were closely related to the amount of root growth, which in turn was increased almost linearly by increased water contents. Rubidium uptake was not consistently affected by the initial water contents to which the roots were exposed, nor was it related to the amount of root growth. There was some evidence that the uptake of the rubidium may be linked to the active transport of ...
