Stabilization Of Residual Soil With Rice Husk Ash And Cement, Hilmi Mahmud
Stabilization Of Residual Soil With Rice Husk Ash And Cement, Hilmi Mahmud
Hilmi Mahmud
Stabilization of residual soils is studied by chemically using cement and rice husk ash. Investigation includes the evaluation of such properties of the soil as compaction, strength, and X-ray diffraction. Test results show that both cement and rice husk ash reduce the plasticity of soils. In term of compactability, addition of rice husk ash and cement decreases the maximum dry density and increases the optimum moisture content. From the viewpoint of plasticity, compaction and strength characteristics, and economy, addition of 6-8% cement and 10-15% rice husk ash is recommended as an optimum amount. © 2004 Elsevier Ltd.

Arkansas Agricultural Experiment Station Research Series
Herbicide evaluation studies on rice were conducted in 2004 at the Rice Research and Extension Center near Stuttgart, AR, in an effort to evaluate new herbicides, herbicide mixtures, and their application timings for weed control and crop tolerance. Results of these studies, in part, provide useful information to producers, fellow researchers, and the Crop Protection Industry for the potential use of new herbicide programs for successful rice production in Arkansas.
Economic Evaluation Of Potential Changes In Farm Program Price Support For Typical Louisiana Rice And Cotton Farming Operations, Manuel E. Aldana
Economic Evaluation Of Potential Changes In Farm Program Price Support For Typical Louisiana Rice And Cotton Farming Operations, Manuel E. Aldana
LSU Master's Theses
Increased government deficit has led the congress to reduce federal spending. Proposed budget cuts are intended to decrease government spending in several areas, including agriculture. Reductions in farm program spending could cause significant adverse effects on the financial situation of many farms, particularly to rice and cotton enterprises, due to their high reliance on farm program payments as a source of income. Representative rice and cotton operations of one, two, three, and four entities as single crop enterprises were considered and developed for use in this study. Farm enterprise sizes were determined by estimating the acreage level at which a …
Effect Of Plant Residue And Water Management Practices On Soil Redox Chemistry, Methane Emission, And Rice Productivity, Manoch Kongchum

LSU Doctoral Dissertations
Approximately 5 % of rice growing area in Louisiana experience poor seedling or stand development attributed to anaerobic decomposition of excess plant residue, which create strongly reducing or toxic soil conditions. This study investigated plant residue and flooding regime effects on soil properties as related to rice growth and seedling development. Field experiments were conducted at several commercial farms in Southwest Louisiana (which have experienced problem with rice stand development) to relate observed restricted rice growth to soil redox chemistry and other chemical and physical properties. Field experiments were also conducted at the Crowley Rice Research Station in which various …
