      An adequate description of soil moisture movement is necessary for solution of agriculturally oriented problems such as irrigation, drainage and runoff control. Three approaches for determining the hydraulic properties of ...
    • Determination of the erodibility factor of soils and lignite spoils 
      Rubio-Montoya, David (Texas A&M University. Libraries, 1981)
      Surface strip mining is currently the fastest way to recover lignite and bituminous coal. The strip mining results in the disturbance of large acreages of land. However, specific management of the spoils is required to ...
    • Determining the Transpiration Rate of Peach Trees Under Two Trickle Irrigation Regimes 
      Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Rodriguez, P. B.; Van Bavel, C. H. M.; Reeder, E. L. (Texas Water Resources Institute, 1980-12)
      The scientific design and management of a modern irrigation system requires that the designer or manager have knowledge of site and plant criteria such as infiltration, drainage, soil fertility, plant water needs, and plant ...
    • Effect of carbon dioxide enrichment on diffusive resistance for gas exchange, water use, and water use efficiency of greenhouse tomatoes 
      Shaer, Yacoub Adib (Texas A&M University. Libraries, 1985)
      Three adjacent ventilated mini-greenhouses (MGH) made of clear polyethylene film, transmitting natural solar radiation, were enclosed in a conventional inflated polyethylene greenhouse. In each MGH, an equal number of ...
    • Evaluation of a model which predicts whole plant respiration from photosynthesis and biomass 
      Gay, Scott Lallier (Texas A&M University. Libraries, 1981)
      Over time, whole plant growth is nearly the balance between photosynthesis and respiration. This research consisted of devising and testing a model which predicts plant respiration rates from knowledge of the photosynthesis ...
    • Growth model of greenhouse tomatoes with carbon dioxide enrichment : development and experimental tests 
      Kano, Atsushi (Texas A&M University. Libraries, 1985)
      A deterministic, compartmental growth model of greenhouse tomato plants, written in Pascal computer language, was developed based on a leaf assimilation model and a model of a theory that the photosynthesis rate is controlled ...
    • Improved Water and Nutrient Management Through HighFrequency Irrigation 
      Howell, T. A.; Brown, K. W.; Newton, R. J.; Redden, D. L.; McFarland, M. J. (Texas Water Resources Institute, 1981-03)
      High frequency irrigation implies the uniform, frequent application of water to crops. The fequency may range from several irrigations per week to daily irrigation to even several irrigations per day in greenhouse and ...
    • The Influence of Trickle Irrigation on the Quality of Irrigation Return Flow 
      Brown, K. W.; Gerard, C. J.; DeMichele, D. W.; Sharpe, P. J. H.; Hipp, B. W. (Texas Water Resources Institute, 1976-03)
      The influence of trickle irrigation on the quality of irrigation return flow was investigated in a field study and by means of computer simulation models. Six undisturbed buried monolith lysimeters were utilized to quantify ...
    • An Investigation of the Return Flow from Irrigated Land 
      Brown, K. W.; Gerard, C. J.; DeMichele, D. W.; Sharpe, P. J. H.; Hipp, B. W. (Texas Water Resources Institute, 1974-09)
      Recent trends in agricultural have lead to the intensification of crop production in areas with long growing seasons and ample solar radiation. Unfortunately, these areas also often have limited water supplies, and the ...
    • A model of metabolizing sinks in plants 
      Keener, Melvin E. (Texas A&M University. Libraries, 1977)
      The basic objectives of this study was to build a model that describes the physiology of sinks. This also includes the process of unloading assimilates from the phloem. The metabolic steps necessary to describe a typical ...
    • Observed and estimated (ERHYM-II model) water budgets for South Texas rangelands 
      Weltz, Mark Allen (Texas A&M University. Libraries, 1987)
      A three-part study was conducted at the La Copita Research Area, 20 km southwest of Alice, in the eastern Rio Grande Plain of Texas. The research tested the hypothesis that honey mesquite-dominated shrub clusters have ...
    • The potential of an Fe waste by-product as an Fe fertilizer in alkaline soil 
      Parkpian, Preed (Texas A&M University. Libraries, 1983)
      An Fe dust waste accumulates as a by-product from the steel industry and poses a disposal problem. Since the waste contains approximately 43% Fe, 5.4% Zn, and 1.9% Mn, it shows potential for recycling as a plant food. ...
    • Response of Peanuts to Irrigation Management at Different Crop Growth Stages 
      Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Dahmen, P. (Texas Water Resources Institute, 1980-12)
