“…Infiltration changes systematically with field position in furrow irrigation, interacting with fertilizer practices and compaction and affecting potato yield and grade (Trout and Mackey, 1988a,b;Trout et al, 1994;Sojka et al, 1993a,b;Westermann and Sojka, 1996). These factors caused a large shift from furrow irrigation to sprinkler irrigation of Pacific Northwest potato.…”

Polyacrylamide (PAM) in furrow irrigation water eliminates 94% of runoff sediment. Higher infiltration (15-50%) can result in upperfield uverirrigation. We hypothesized that PAM would lengthen advance time, but that interactions with flow rate and wheel-track (WT) Ihrrows would occur, influencing erosion and infiltration with potential for improved water management. A 2-yr study conducted on 1.5% slope Portneuf soil (Dnrinodic Xeric Haplocalcid) was irrigated with 10 g tn-1 PAM in advancing 23 L min-1 furrow streams (reduced to 19 L min-1 after advance) (PAM treatment, 11) or without PAM (control, C). Initial inflows in 1994 were 23 L min-1 (normal flow rate, N) or 45 L min-1 (high flow rate, H) with or without PAM. The application of PAM at 23 L min -1 (PN) increased 2-yr mean advance time 33% and reduced runoff soil loss 88% compared with controls (CN). Polyacrylamide applied at 45 L min-' (PH) reduced advance time 8% and soil loss 75% compared with CN, whereas untreated 45 L min-1 inflows (CH) cut advance time 42% but raised soil loss 158%. The CH and PH raised infiltration 11 and 35% more than CN respectively. Polyacrylamide halted erosion in all furrows, but in WT furrows had no effect on advance time and Bide infiltration effect after two or three irrigations. This is mainly attributed to erosion and deposition increasing control-furrow wetted perimeters; accumulated PAM may also slightly affect seal conductivity. Polyacrylamide raised aggregate stability from 54

/ Inorganic C reactions are among the most important chemical reactions that occur in irrigated soils and may contribute to the total amount of C sequestered in those soils. Because CO2 can escape from soils to the atmosphere or return to precipitate carbonate minerals, soils are open systems with regard to inorganic C. 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 total C (inorganic + organic C) in soil decreased in the order IMP>ICT>IP>NSB. We use our findings to estimate that amount of possible inorganic and total C sequestration if irrigated agriculture were expanded by 10%. If irrigated agricultural land were expanded by 10% worldwide and NSB were converted to IMP, a possible 1.60 x 108 Mg inorganic C (2.78% of the total C emitted in the next 30 years) could be sequestered in soil. If irrigated agricultural land were expanded by 10% worldwide and NSB were converted to ICT, a possible 1.10 x 109 Mg inorganic C (1.87% of the total C emitted in the next 30 years) could be sequestered in soil. If irrigated agricultural land were expanded worldwide and NSB were converted to IP, a possible gain of 2.6 x 108 Mg inorganic C (0.04% of the total C emitted in the next 30 years) could be sequestered in soils. Inorganic C sequestered from land-use changes have little potential to make a significant impact on the concentration of atmospheric CO 2.However, when coupled with organic C and altering land use to produce crops on high-output irrigated agriculture while selected less productive rain-fed agricultural land was returned to temperate forest or native grassland, there could be reductions in atmospheric CO2 .In 1992, nearly all countries of the world signed the Framework Convention on Climate Change. The longterm goal of this legislation is to stabilize the concentration of greenhouse gases in the atmosphere at concentrations that prevent interference with the climate system. To stabilize or reduce CO2 concentrations, emissions of the gas must either be reduced or transferred from the atmosphere to marine or terrestrial ecosystems. Irrigating arid and semiarid regions may be one method to contribute to C sequestration and, ultimately, reduce atmospheric CO 2 concentrations. The addition of water to arid and semiarid soils increases plant growth and, ultimately, C deposition into soil. Entry and others (2002) found that if irrigated agriculture were expanded by 10% into irrigated pastures, a potential increase of 9.3 X 109 Mg organic C (16.3% of
