Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Date: August 1970
Creator: Ferguson, Patricia Kaspar
Description: The purpose of this study was to see if any soil bacteria were able to use pentachlorophenol or sodium pentachlorophenate either aerobically or anaerobically as a sole carbon source, to see if any soil bacteria could survive in high concentrations of sodium pentachlorophenate, to determine the maximum concentration of sodium pentachlorophenate which permitted the growth of some soil bacteria, to see the effects of varying concentrations of sodium pentachlorophenate on the growth curves of soil bacteria capable of growing in its presence, and to see if any soil bacteria could degrade sodium pentachlorophenate.

A Study of Soil Erosion and its Control in the United States with Special Reference to Texas

A Study of Soil Erosion and its Control in the United States with Special Reference to Texas

Date: June 1939
Creator: Merrell, Jesse Byron
Description: A study of soil erosion in the United States, especially in Texas, which brings attention to the causes of soil erosion under the existing system of farm management. The material gathered and compiled and arranged under certail main heading. Two chapters deal with present and immediate causes of erosions and their results. One full chapter takes up the history of the conservation movement and attempts to show how slow Texans have been in comparison with some of the other states of the United States. The study calls for further research, teaching of better land-use, raising awareness of soil erosion causes and conditions.

A Correlation of Humus with Water Content and Crop Rotation in San Saba and Denton Clays, Denton County, Texas

A Correlation of Humus with Water Content and Crop Rotation in San Saba and Denton Clays, Denton County, Texas

Date: August 1939
Creator: Culwell, John Walton
Description: A study of the humus content and the water content of San Saba clay and Denton clay. Studies show that the physical properties of soil are conducive to moisture retention and the availability of moisture to plants.

The Effects of the Soil Conditioner, Superbio, Upon the Cellulose Decomposing Bacteria and the Crop Yield of a Soil

The Effects of the Soil Conditioner, Superbio, Upon the Cellulose Decomposing Bacteria and the Crop Yield of a Soil

Date: August 1968
Creator: Gunn, Bruce Alan
Description: The purpose of this investigation was to determine if a commercial soil conditioner, Superbio, can improve crop yield, and if the "advertised" soil improvement might be due to an increase in the activity and numbers of aerobic cellulose decomposing bacteria following treatment.

Seasonal Survey of Actinomycetes in Twenty Denton County, Texas, Soils

Seasonal Survey of Actinomycetes in Twenty Denton County, Texas, Soils

Date: 1949
Creator: Hudgins, Gladys
Description: This investigation has had for its aim a further study of actinomycete flora of twenty Denton County, Texas, soils. The problem has evolved itself into, first, a seasonal analysis for the number of actinomycetes in each of the twenty soils; second, a determination of the types of soils that contain the greatest number of actinomycetes in each cultivated and uncultivated land; third, a determination of soil moisture and pH; and fourth, an attempt to correlate these factors with the number of actinomycetes found in each soil type.

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

Date: 1950
Creator: Heather, Carl D.
Description: In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.
