- Long-term polyacrylamide formulation effects on soil erosion, water infiltration, and yields of furrow-irrigated crops
Water soluble anionic polyacrylamide (WSPAM) is an important tool employed by producers to reduce erosion associated with furrow irrigation. Two formulations of WSPAM are used in agriculture, although few if any reports comparing their effectiveness are published. A long-term field study was condu...
- THE INFLUENCE OF HIGH APPLICATION RATES OF POLYACRLYAMIDE ON MICROBIAL DIVERSITY IN AN AGRICULTURAL SOIL
Agricultural runoff is a major source of nutrients, pesticides and enteric microorganisms to surface and ground waters. Water soluble anionic polyacrylamide (PAM) is a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1 to 10 grams per square meter in f...
- COMPOST AMENDMENTS IN A WOOD CHIP - POLYACRYLAMIDE MEDIUM DECREASED VERTICILLIUM DAHLIAE INFECTION ON POTATO
The lack of success of biological control with soilborne diseases is primarily due to the introduction of the biological control organism into a sub-optimal environment. Indigenous soil microorganisms contribute to disease suppression in cropping systems by reducing and competing with pathogen popu...
- INFLUENCE OF IRRIGATED AGRICULTURE ON SOIL CARBON AND MICROBIAL COMMUNITY STRUCTURE
Increasing the amount of carbon (C) in soils is one method to reduce the concentration of carbon dioxide in the atmosphere. We measured organic C stored in Southern Idaho soils having long term cropping histories that supported native sagebrush vegetation (NSB), irrigated moldboard plowed crops (IMP...
- IRRIGATION INCREASES INORGANIC CARBON IN AGRICULTURAL SOILS
Inorganic carbon reactions are among the most important chemical reactions that occur in irrigated soils and may contribute to the total amount of carbon sequestered in those soils. Since carbon dioxide can escape from soils to the atmosphere or return to precipitate carbonate minerals, soils are o...
- Carbon and nitrogen stable isotope ratios can estimate anionic polyacrylamide degradation in soil
Water soluble anionic polyacrylamide (PAM) is a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1 to 10 g/m-3 in furrow irrigation water. PAM degradation has not directly been measured in soil or water. Natural abundance of the carbon (13C/12C) isoto...
- IRRIGATION INCREASES CARBON IN AGRICULTURAL SOILS
We measured inorganic and organic C stored in southern Idaho soils having long term land use histories that supported native sagebrush vegetation (NSB), irrigated moldboard plowed crops (IMP), irrigated conservation (chisel) tilled crops (ICT) and irrigated pasture systems (IP). Inorganic C and tot...
- CARBON SEQUESTRATION IN IRRIGATED PASTURES
Carbon sequestration potential for irrigated grazing lands is significant. We measured organic and inorganic carbon stored in southern Idaho soils having long-term land use histories that supported native sagebrush vegetation (NSB), irrigated pasture systems (IP), irrigated conservation tillage sit...
- IRRIGATION INCREASES CARBON IN AGRICULTURAL SOILS
We measured organic and inorganic C stored in southern Idaho soils having long term land use histories that supported native sagebrush vegetation (NSB), irrigated moldboard plowed crops (IMP), irrigated conservation -chisel- tilled crops (ICT) and irrigated pasture systems (IP). Inorganic C and to...
- IRRIGATED AGRICULTURE AND TILLAGE PRACTICES IMPACT MICROBIAL COMMUNITY STRUCTURE
Intensively managed crop or pastureland has potential for C gain through the use of improved grazing regimes, fertilization practices and irrigation management. Soil microbial diversity is important because it is often regarded as an index of soil health. Organic C and microbial structural diversit...
