Chemical properties of soils related to seasonal fluctuations in exchangeable potassium

Creator:: Etter, Harold Mac Donald
Abstract:: Representative sites of the Dayton, Woodburn, Jory, Quillayute, Astoria, Willamette, Walla Walla, Deschutes, Laki and Owyhee soil series were investigated for seasonal changes in exchangeable potassium in air dry samples. No consistent seasonal variations were found which could be attributed to wetting and drying in the field. Cropping reduced the...

The effects of versene on dividing sea urchin eggs

Creator:: Hanson, James Charles
Abstract:: Developing sea urchin eggs (Strongylocentrotus purpuratus), reared at 15° C, were subjected to single 15-minute treatments with disodium versenate in calcium-free sea water, applied at 10-minute intervals, from 4 minutes after insemination to the second cleavage. These versene pulses produced specific degrees of retardation in the mitotic process and delayed...

Thornthwaite's moisture index as a measure of the intensity to which harvested cropland is devoted to corn under natural climatic conditions

Creator:: Hall, Robert Newell
Abstract:: Moisture has long been identified as one of the major limiting factors in the distribution of agricultural land use practices. However, the importance of any environmental element can only be determined by considering how it is affected by its relationship with other elements of the environment. Thornthwaite's moisture index attempts...

Sorption of NH₃ in a dry system in relation to the chemical properties of clays and soils

Creator:: James, D. W. (David W.), 1929-
Abstract:: The physico-chemical reactions of ammonia in soils and clays have many practical and theoretical implications. On the one hand, large quantities of anhydrous ammonia are used annually in agriculture for fertilizer; the dry gas is applied directly to the soil by simply injecting it below the ground surface. On the...
