Bromoxynil degradation in a Mississippi silt loam soil.
BACKGROUND The objectives of these laboratory experiments were: (1) to assess bromoxynil sorption, mineralization, bound residue formation and extractable residue persistence in a Dundee silt loam collected from 0-2 cm and 2-10 cm depths under continuous conventional tillage and no-tillage; (2) to assess the effects of autoclaving on bromoxynil mineralization and bound residue formation; (3) to...
متن کاملSeeded, Delayed-Flood Rice on a Silt-Loam Soil
Urea is the most widely used nitrogen (N) fertilizer in direct-seeded, delayed-flood rice production. Urea fertilizer is susceptible to loss as ammonia gas to the atmosphere if not flooded in a timely manner. A urease inhibitor [i.e. N-(n-butyl) thiophosphorictriamide; NBPT] is recommended when a timely flood cannot be established. Recent research has indicated that when relative humidity (RH) ...
متن کاملTillage effects on soil organic carbon distribution and storage in a silt loam soil in Illinois
Interest in tillage impacts on sequestration of soil organic carbon (SOC) has increased greatly during recent years. The use of reduced and no-tillage (NT) practices generally increases the SOC concentration in surface few centimeters when compared to conventionally tilled soils. However, use of conservation tillage does not always result in increased SOC storage overall. The effects of sample ...
متن کاملInteractions of tillage and soil depth on ̄uometuron degradation in a Dundee silt loam soil
Fluometuron (N,N-dimethyl-N0-[3-(tri ̄uoromethyl)phenyl]urea) is the most widely used soil applied herbicide in cotton (Gossypium hirsutum) production in the Southeastern United States. Thus, there is a need to understand the persistence of this herbicide under various crop management systems in regards to both herbicide ef®ciency and environmental fate. The effects of long-term no-tillage pract...
متن کاملConservation Tillage Systems for Corn Production on a Loessial Silt Loam and Alluvial Clay in Louisiana
Corn acreage has increased in recent years in Louisiana. Much of this is on mixed to heavy Mississippi River alluvial soils and to a lesser extent on loessial silt loams of the Macon Ridge. Each of these soil groups are unique in their phys ical and chemical characteristics and different management strategies may be required to produce optimal yield. Research has indicated that corn performs b...
