(Texas A&M University, 2007-04-25)Mineral nutrients imported in composted dairy manure (CDM) and municipal biosolid (CMB) amendments for highway-rights-of-way and urban landscapes can pose a threat to surface water quality. Treatments were developed to ...
-
(Texas A&M University. Libraries, 1981)Laboratory investigations were carried out with the marine mysid, Praunus flexuosus, to assess the degree of coupling between glutamate dehydrogenase (EC 1.4.1.3; GDH) activity and the rate of whole animal ammonium excretion. ...
-
(Texas A&M University. Libraries, 1978)Chemical fixation of dinitrogen has been performed under mild conditions in homogeneous and heterogeneous systems. In heterogeneous system electron donor-acceptor complexes of iron phthalocyanine, ruthenium phthalocyanine, ...
-
(2015-08-05)Government regulations on emission standards and constantly fluctuating fuel availability and prices have led to the need of more readily usable and available models for power generating combustors. A common, versatile, ...
-
(2012-07-16)Upwelling, atmospheric nitrogen (N2) fixation by cyanobacteria, and freshwater inputs from the Mississippi River system have been shown to stimulate new production by alleviating nitrogen (N) limitation in the northern ...
-
(2017-02-22)Cropping systems involving legumes are increasing due to the costs and environmental concerns attributed to N fertilizer. A green manure cover crop in a cropping system can benefit the soil by improving fertility and ...
-
(2017-07-14)Growing quality turf in shade is a significant management concern for many turf managers. Proper turfgrass selection for shaded environments can be challenging due to difficulty in quantifying necessary light levels ...
-
(2019-03-27)Industrial Gas market is expected to grow to $106 billion from $76 billion by 2022 parallel to the global energy and chemical production sector growth. Air separation is one of the major technologies utilized within this ...
-
(Texas A&M University. Libraries, 1980)The most generally limiting nutrient to growth of forage grasses is fixed nitrogen in the form of No3- or NH4+. Dinitrogen fixation by bacteria associated with forage grass roots in a system which would provide plants with ...
-
(2012-07-11)Bahiagrass (paspalum notatum), a forage resource in the southern United States, often has lower forage quality than other forages, but may require fewer nutrient inputs. Our objectives were to determine the effects of N ...
-
The effect of nitrogen fixation on the protein quality of southernpeas, Vigna unguiculata (Cowpeas) (Texas A&M University. Libraries, 1981)The effects of nitrogen fixation on protein quality of southernpeas were studied. Differences in levels of nitrogen fixation were induced through variety selection and inoculation with Rhizobium bacteria. Growing seasons ...
-
(2009-05-15)Freshwater inflows are essential to the health of estuaries and minimum discharge levels must be maintained in order to sustain a healthy ecosystem. Due to the predicted 50% increase in urban population growth along the ...
-
(2012-07-16)Intensive biomass production in emerging bioenergy systems could increase nonpoint-source sediment and nutrient losses and impair surface and groundwater quality. Recycling biochar, a charcoal byproduct from pyrolysis of ...
-
(Texas A&M University. Libraries, 1987)Nitrogen-fixing bacteria in the rhizosphere of cereal grasses may reduce the fertilizer nitrogen requirements of grass crops by providing them with fixed nitrogen. This study evaluated the effects of oxygen partial pressure, ...
-
(2014-06-03)The fate of carbon in the ocean determines both the amount of CO_(2) that can be sequestered and the amount of sustainable biomass. Compartmentalization into new and regenerated production allows a first order estimate of ...
-
(Texas A&M University, 2007-09-17)Six Quarter Horse yearling fillies were used in a duplicated 3 x 3 Latin square designed experiment to evaluate the technique of nitrogen retention as a response criterion for amino acid studies in the horse. The yearlings ...
-
(Texas A&M University. Libraries, 1984)A large-scale culture system for Chlorella vulgaris has been established and growth conditions determined for optimal production of nitrate reductase. Nitrate reductase was purified from collected cells. A novel method for ...
-
(Texas A&M University. Libraries, 1980)Cowpea, because of its ability to fix atmospheric nitrogen, coupled with its drought tolerance and ease of digestion, has become an important proteinaceous crop throughout the semi-arid regions of the world. Little research ...
-
(2018-07-06)The coastal Gulf of Mexico (GOM) and Coastal Sea off Korea (CSK) both suffer from eutrophication and/or hypoxia, both of which are driven mainly by humans. We compared two different regions with different nitrogen input ...
-
(Texas A&M University. Libraries, 1983)Drought resistance and biological nitrogen fixation (BNF) potential of 437 diverse cowpea genotypes were determined. Plants were grown in irrigated and dryland plots in 1979 and 1980 near Lubbock, Texas. Drought resistance ...
