(Texas A&M University. Libraries, 1982)Three soils and 10 plant species were utilized to determine levels of plant accumulation of cobalt, sorption of cobalt in soil, influence of three management techniques on cobalt availability, and evaluation of four ...
-
(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. ...
-
(Texas A&M University. Libraries, 1983)A thorough review of the literature regarding design methods for lateral load behavior of foundation piles has been made. The most popular and versatile design technique is solution of the governing differential equation ...
-
(Texas A&M University. Libraries, 1973)The second order Cauchy elastic constitutive relation was shown to adequately model the qualitative nonlinear stress-strain loading behavior of a dry, dense, cohesionless sand for drained conditions and rate independent, ...
-
(Texas A&M University. Libraries, 1986)Relationships between pedology, geomorphology and stratigraphy were investigated in a dry valley of Niger, the Dallol Bosso. The sediments of the Dallol are mostly fluvial sands which have been reworked by eolian processes. ...

-
(Texas A&M University. Libraries, 1987)Susceptible crop species may exhibit symptoms of iron (Fe)-deficiency chlorosis when grown on high pH, calcareous soils. A series of field and greenhouse experiments was conducted to determine whether differences exist ...
-
(Texas A&M University. Libraries, 1991)Decreasing yield of crops grown in soils of the Mbo Plain has been attributed to deficiencies of soil P. The objectives of this study were to classify these soils using the United States Soil Taxonomy System and to determine ...
-
(Texas A&M University. Libraries, 1977)A three-year field plot study was conducted to determine the feasibility of raising corn ('Texas 28A '), sorghum ('Top Hand'), and two cultivars of soybean ('Hill' and 'Lee') on leveled mine spoil banks. The location of ...
-
(Texas A&M University. Libraries, 1986)An integrated soil genesis, phosphorus and micronutrient (Fe, Mn, Cu, Zn) study was conducted for seven northern Cameroon Vertisols and associated Alfisols. Vertisols developed from Precambrian schist are classified as ...
-
(Texas A&M University. Libraries, 1989)The pedons investigated are generally weakly differentiated and are slightly weathered. The Gujranwala profile is the most developed among the three. The field and laboratory observations about the occurrence of argillans ...
-
(Texas A&M University. Libraries, 1980)Some soils of the Texas coastal plain are saturated for several months of each year, but do not exhibit the low chroma colors normally associated with poor drainage. Without direct measurement of the water table levels in ...
-
(Texas A&M University. Libraries, 1985)Corrosion in the United States is a major economic problem with losses in 1984 estimated at $125 billion (Siebert, 1984). A larger portion of this corrosion can be attributed to degradation of underground metallic structures. ...
-
(Texas A&M University. Libraries, 1990)When crops are cultivated in a row configuration, latent heat flux from the soil (LE[s]) and crop canopy (LE[c]) influence the energy and water balance of the crop. Field experiments were conducted in Lubbock, TX to examine ...
-
(Texas A&M University. Libraries, 1987)The objective of this study was to investigate the solubility of phosphorus, iron, and calcium carbonate in flooded soil. Soil solutions were collected and analyzed for the major inorganic solution constituents. Solubility ...
-
(Texas A&M University. Libraries, 1985)A series of experiments were conducted in solution culture in the greenhouse, growth chamber, controlled environment room, and in the field on P-deficient rice soil at the Texas A&M University Agricultural Research and ...
-
(Texas A&M University. Libraries, 1990)Relationship between landscape position and soil characteristics such as moisture regime, phosphorus fixing capacity, and acidity were investigated on two toposequences of western Niger (West Africa). The toposequences ...
-
(Texas A&M University. Libraries, 1986)In recent years, there has been an increase in the use of flexible plastic pipes as buried conduits even though much of the soil-pipe behavior has not been fully understood. Present design approaches either involve the use ...
-
(2018-10-29)Polyaromatic hydrocarbons (PAHs) and their interaction with plants have received an abundance of attention from the scientific community, as they are ubiquitous and recalcitrant in the environment. As some PAHs are known ...
