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.

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.

Date: November 1989
Creator: Acevedo, Miguel F.; Andressen, Rigoberto; Azocar, Aura; Bisbal, Evelyn; Comerma, Juan; Corvo, Fernando et al.
Description: Report on a Modeling Crop and Climate Change workshop. The objectives of the workshop were: 1) train Venezuelan scientists in the use of agricultural models IBSNAT program (International Benchmark Sites Network for Agrotechnology Transfer), including discussions about their applicability and the acquisition of knowledge about the data needed for proper simulation and validation, 2) Calibrate the model of maize (CERES) for different cultivars and different regions of Venezuela using data from soil and climate corresponding to various tests, 3) Carry out model simulations under various climate scenarios to assess their potential effects on crops, 4) To strengthen the cooperation between users of IBSNAT models to make necessary tests to get a better database application thus facilitating validation and calibration of these models, and 5) To establish plans for future agricultural and meteorological research in the context of global climate change.

Distribution of a Novel Gram Negative, Capsule-Forming Bacterium

Distribution of a Novel Gram Negative, Capsule-Forming Bacterium

Date: December 1997
Creator: Hughes, Roxana Bejarano
Description: A novel Gram negative, capsule-forming bacterium was previously isolated in Dr. G. Roland Vela's laboratory. The distribution of this bacterium in soils from various locations was investigated. Soil samples from 188 locations around the world were examined. Isolates of the bacterium were obtained from 50 of these soils, with 48 of the isolates found in soils from the southwestern United States and northern Mexico. This suggests that this region is the natural habitat of the bacterium. The other two isolates were obtained from Madrid, Spain and Taipei, Taiwan. None were found in soils from South America or Australia. A lack of variation in morphology and physiological properties in the isolates suggests that a homogeneous population exists, even from widespread geographical locations.
