Influence Of Planting System On Surface Soil, Physical Conditions And Soil Water Relations, D Tennant

Experimental Summaries - Plant Research

Influence of planting system on surface soil, physical conditions and soil water relations. The availability of soil water for crop use can this way be influenced by planting system. Various aspects of soil water relations were examined in varying detail at three sites - Wongan Hills, Avondale and Merredin, over the 1979 and 1980 growing seasons. Some of this soil water data are presented here. The Department of Agriculture initiated a programme in 1977 to investigate and compare crop performance under several planting systems. This project was part of this programme and had as its objectives: 1. Measurement of soil …

The Headquarters of dry land pasture project was transferred to Merredin from Perth for the 1980 season. The aim of the programme is to ascertain the place that legume pasture might play in the dryland farming system. It is aimed to test and introduce improved varieties of pasture species and develop management systems which will improve pasture production and persistence in the low rainfall areas of the wheatbelt. 1.

The Effect Of Dissolution Of Volcanic Glass On The Water Chemistry In A Tuffaceous Aquifer, Rainier Mesa, Nevada, Art F. White, Hans C. Claassen, Larry Benson

United States Geological Survey: Staff Publications

Geochemistry of ground water associated with the Tertiary tuffs within Rainier Mesa, southern Nevada, was investigated to determine the relative importance of glass dissolution in controlling water chemistry. Water samples were obtained both from interstitial pores in core sections and from free-flowing fractures. Cation compositions showed that calcium and magnesium decreased as a function of depth in the mesa, as sodium increased. The maximum effect occurs within alteration zones containing clinoptilolite and montmorillonite, suggesting these minerals effectively remove bivalent cations from the system.

Comparisons are made between compositions of ground waters found within Rainier Mesa that apparently have not reacted …

Hydrogeologic And Geochemical Investigation Of The Boone-St. Joe Limestone Aquifer In Benton County, Arkansas, Albert E. Ogden

Arkansas Water Resources Center Technical Reports

The Boone-St. Joe limestone aquifer is an important unconfined aquifer for rural residents of Benton County, Arkansas. Pumping tests indicate a large range in production capability of the aquifer. The coefficient of transmissibility and specific capacity range from 24.8 to 24640 gpd/ft and 0.03 to 30 gpm/ft, respectively. No statistical relationship at a = 0.10 was found between each of these parameters and photo-lineament proximity. Drillers' estimated well yield (gpm) also showed no relationship to photo-lineament proximity. It is therefore concluded that choosing well sites along photo-lineaments for higher production is not as reliable for karstified carbonate aquifers such as …

The Origin Of Fine Scale Acoustic Stratigraphy In Deep-Sea Carbonates, Larry A. Mayer

Affiliate Scholarship

In this paper we investigate the origin and geologic significance of the closely spaced high-frequency subbottom acoustic reflectors characteristic of pelagic carbonates. A detailed survey was conducted of a small area in the equatorial Pacific with the Marine Physical Laboratory's Deep-Tow instrument package, providing high-resolution 4-kHz profiles and precise positioning of core samples. The cores were sampled at closely spaced intervals for sound velocity and saturated bulk density. Acoustic impedances were calculated, and a reflection coefficient log determined for the upper 10 m of the sediment column. The reflection coefficient log revealed no interfaces with large reflection coefficients that correlated …

Changing Fields: Agricultural Land Use Changes In Nebraska 1925-1974, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

The series of graphs and maps which follow illustrate agricultural land use changes in Nebraska from 1925 to 1974. With these graphs and maps, the major agronomic crops of corn (dryland and irrigated), wheat, sorghum and soybeans are analyzed. The purpose of this analysis is to provide a pictorial history of Nebraska's ever-changing cropping system and, hopefully, to stimulate ideas and discussion with regard to trends and future directions. The Nebraska Water Resources Center is deeply interested in both the past and the future of Nebraska's agriculture because of the demands which agriculture places on the state's water resources. An …

Turbulence Spectra Above A Vegetated Surface Under Conditions Of Sensible Heat Advection, Raymond P. Motha, Shashi B. Verma, Norman J. Rosenberg

National Drought Mitigation Center: Faculty Publications

Spectra of vertical and horizontal velocity, air temperature and humidity fluctuations were analyzed from measurements made over a well-watered alfalfa crop under conditions of sensible heat advection. Vertical velocity and air temperature spectra as well as cospectra of momentum, sensible heat and water vapor were found to be dependent on atmospheric thermal stratification. These spectra and cospectra were shifted toward higher frequencies under advective as compared to lapse conditions. These results indicate that the predominant eddy sizes are relatively smaller under advective conditions. Humidity spectra, on the other hand, were independent of daytime thermal stratification conditions but were influenced by …

Uranium Transport In The Walker River Basin, California And Nevada, Larry Benson, D. L. Leach

United States Geological Survey: Staff Publications

During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within a closed hydrologic basin as well as providing a basis for the design of geochemical reconnaissance studies for the Basin and Range Province of the Western United States. Spring and tributary data are useful in locating areas containing anomalous concentrations of uranium. However, agricultural practices obscure the presence of known uranium …

COMMENTS 1. No insect problems experienced and broadleaf weeds effectively controlled by spraying. Septoria· leaf spot incidence insufficient to affect yields. 2. Little effect of time of planting on either total dry matter or grain yield. Crop received about 70% of the average May-October rainfall with a very dry September-October. Perhaps the distribution of rainfall allowed a similar pattern of water use, and total water use by each planting time. 3. There is probably a significant effect of Nitrogen regime on grain yield.
