Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett Jul 1986

Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett

Soil Science News and Views

An experiment was conducted for a period of three years, 1982, 1983 and 1984, in order to evaluate the effects of soil water stress and irrigation on growth, yield and quality of burley tobacco at Spindletop Farm, Lexington. The variety KY 21 was grown all three years. Three treatments were used in the experiment: (1) check, rainfall only, not irrigated, (2) well watered, rainfall plus supplemental irrigation, and (3) water stressed beginning 50 days after transplanting. The soil of treatment 3 was covered with black plastic to prevent rainfall from entering the soil.


Abatement Of Nitrate Pollution In Groundwater And Surface Runoff From Cropland Using Legume Cover Crops With No-Till Corn, M. Scott Smith, Jac J. Varco Jul 1986

Abatement Of Nitrate Pollution In Groundwater And Surface Runoff From Cropland Using Legume Cover Crops With No-Till Corn, M. Scott Smith, Jac J. Varco

KWRRI Research Reports

Agricultural practices can have a significant impact on water quality. The effects of leguminous winter cover crops on leaching of NO-3; from soil have been investigated in this project. Legume cover crops, by fixation of atmospheric N, can reduce the amount of fertilizer N required to produce summer grain crops. The methods initially used to evaluate cover crop effects on No; transport included suction probe lysimeters and measurement of NO-3; in soil samples collected to a depth of 90 cm. These measurements demonstrated extreme spatial variability in NO-3; distribution and water …

Natural resources published reports

Kununurra Region

3rd edition

A small experimental farm was first established on the Ord River in 1941. This farm was relocated in 1945 to what is now known as the Frank Wise Institute of Tropical Agriculture.

The first stage of the Irrigation Scheme which included the Diversion dam was completed by 1963 and by 1966, 31 irrigated farms had been established.

In 1967 the second stage was commenced and by 1972 the main dam had been completed.

Cotton was the major crop until 1974. In the wet season of that year 3642 hectares was devoted to cotton. Various crops such …

Benthic Foraminifera And Paleoenvironments Of The Arcola Limestone Member Mooreville Formation (Campanian) In Eastern Mississippi And Western Alabama, Julia K. Palmer Jul 1986

Benthic Foraminifera And Paleoenvironments Of The Arcola Limestone Member Mooreville Formation (Campanian) In Eastern Mississippi And Western Alabama, Julia K. Palmer

OES Theses and Dissertations

Eighty-one species of benthic foraminifera have been recovered from chalky marls of the upper Mooreville Formation including the Arcola Limestone Member, and the basal Demopolis Formation located in five sections in east-central Mississippi and west-central Alabama. These species have been described and seventy-nine illustrated. Analysis of the environmental or depth preferences of abundant species together with planktonic percentages and benthic species diversity, indicates that the chalky marls were deposited in a broad shallow shelf sea (subtidal conditions less than 100m) greatly influenced by open ocean conditions. The benthic assemblage is composed of a mixture of typically neritic and bathyal species …

Long-Term Effects Of Tillage On The Retention And Transport Of Soil Water, H. D. Scott, L. S. Wood, W. M. Miley

Arkansas Water Resources Center Technical Reports

Quantitative measurements were made of the physical and chemical properties of two virgin prairie soils, Crowley and Jay, that remain in their native Arkansas environments and of similar soils that had been tilled extensively. Comparisons were made of soil properties at several depths. When compared with the tilled soils the virgin soils had higher organic matter contents, saturated hydraulic conductivities and water retained at several applied pressures. Bulk densities and hydraulic resistances were lower in the virgin soils. For the Crowley silt loam, values of pH and elemental contents of the virgin soil were higher than those of the tilled …


Algal Growth Potentials And Heavy Metal Concentrations Of The Primary Streams To Upper Beaver Lake, Richard L. Meyer, W. Reed Green, Kenneth F. Steele, Diana Wickliff Jun 1986

Algal Growth Potentials And Heavy Metal Concentrations Of The Primary Streams To Upper Beaver Lake, Richard L. Meyer, W. Reed Green, Kenneth F. Steele, Diana Wickliff

Arkansas Water Resources Center Technical Reports

Meyer and Green (1984) demonstrated the probable inhibition of algal growth potential by heavy metals in upper Beaver Lake. Upper Beaver Lake receives water from three tributaries. One contains a small reservoir and the combined streams receive sewage input. Collections were made approximately monthly at eight sites for the Algal Assay Bottle Test (AABT) and heavy metal analysis. In general, AABT results indicated that the collections above the sewage lnput were phosphorus limited while those below were nitrogen or combined nitrogen and phosphorus limited. Growth inhibition occurred during summer and early fall at various sites with greater inhibition at the …
