Zaongo, Christophe Guy Ludovic (Texas A&M University. Libraries, 1993)In the Sahel region o f Africa, grain sorghum (.Sorghum bicolor (L.) Moench) is a major human food source. Due to scarce water resources and soil infertility efficient crop water use is a key challenge for sustainable crop ...
-
Folsom, Bobby Lee (Texas A&M University. Libraries, 1975)Soil solution phosphorus (P) concentration and proportions of the total soil solution P originating from applied fertilizer were monitored at 4 day intervals throughout the vegetative growth period of rice (Oryza sativa ...
-
Sunderman, Herbert Dean (Texas A&M University. Libraries, 1976)Nitrate-N and Cl⁻ concentrations were measured in the petioles of cotton plants at intervals during the 1972 and 1973 seasons at three irrigated locations across the Southern High Plains of Texas. Soils at the southern and ...
-
Black, Elwood David (Texas A&M University. Libraries, 1982)Adsorption of P from solution by the limed and unlimed soil and sand samples occurred rapidly during the first minute and then decreased. A gradual sorption of P continued for periods greater than 72 hours. Increasing the ...
-
McFarland, Mark Lee (Texas A&M University. Libraries, 1988)Burial of spent drilling fluids used in petroleum and natural gas exploration was evaluated as an alternative disposal technique for reducing surface soil contamination in western Texas. Simulated reserve pits were constructed ...
-
Skousen, Jeffrey Grant (Texas A&M University. Libraries, 1986)Introducing low-maintenance, perennial, plant species into grass pastures by sod-seeding has been identified as a method for improving forage quality and quantity with fewer cultural inputs, and for providing other plant ...
