“…In this case, large amount of nitrate leaching loss was unavoidable. Halvorson et al (2002) reported that using 15 N-labelled KNO 3 in furrow-irrigated onion field, fertilizer 15 N moved to 1.8 m after irrigation during one growing season. Ramos et al (2002) reported that nitrate leaching represented about 38-70% of total N input in the irrigated-vegetable soils.…”

In a greenhouse experiment with tomato, the N fertilizer reduction potential, tomato yield, N use and environmental implications were examined, in a comparison of site-specific N management with conventional N fertilization during three successive growing seasons from Feb. 2004 to Jun. 2005 in Shouguang, a typical greenhouse vegetable production region in Shandong province, Northern China. Fertilizer N recommendation with site-specific management was based on the difference between N target value and soil initial nitrate-N content (0-0.3 m) with pre-sidedress soil nitrate testing (PSNT) and nitrate-N applied from irrigated water. The same basal dressing of 8, 11 and 8 t ha À1 of chicken manure (supplying 260, 360 and 316 kg N ha À1 in the first, second, and the third growing season, respectively) was broadcasted with conventional N, site-specific N and N from manure three treatments. The N target value with site-specific management was 300 kg N ha À1 in the first season, and then modified to 200 kg N ha À1 in the second and third seasons. In comparison with the fertilizer N applied rate with conventional N management (870, 720 and 630 kg N ha À1 in the three seasons, respectively), site-specific management reduced N fertilizer by 62, 78 and 80% without significant influences on tomato yield. The fruit yield of tomato with only basal dressing manure treatment was significantly decreased in the second season, compared with conventional N management. The nitrate content in 0-0.9 m soil depth with site-specific management was much lower than that with conventional N management in all three seasons. The 53-83% of emitted nitrous oxide (N 2 O) was measured from transplanting to the first sidedressing in the three seasons, strongly related to dryingwetting soil process. As a result, the cumulative emission with site-specific management was only reduced by 38% than that with conventional N management throughout three seasons. Considering N release from mineralization and irrigation water, site-specific N management could efficiently control N application in intensive irrigated-vegetable production region. Thus, it is valuable to obtaining vegetable crops with high yield and economic return while alleviating the risk of environmental pollution. But it is necessary to optimize irrigation regime to minimize N loss through nitrate leaching and N 2 O emission.

“…High rates of N fertilizer (>200 kg N ha −1 ) are usually applied to onion in the western United States to increase overall yield and bulb size, generally without regard to soil testing (Bartolo et al, 1997, Brown, 1997, 2000; Drost et al, 1997; Stevens, 1997). Halvorson et al (2002) reported N fertilizer use efficiency (NFUE) by onion to be about 15%. Sammis (1997) also reported the need for high rates of N on onion to optimize yield in New Mexico, but expressed concern about leaching of NO 3 –N from the root zone and the low NFUE (30%) by onion.…”

“…Although these N fertilizer management guidelines recommend limiting N application when soil N is high, growers often apply N to ensure high yields and large sized onions. Irrigation, crop, and N management practices need to be developed to reduce NO 3 –N leaching potential and improve NUE in Colorado (Halvorson et al, 2002, 2005).…”

Onion (Allium cepa L.) is a high cash value crop with a very shallow root system that is frequently irrigated and fertilized with high N rates to maximize yield. Converting from furrow-irrigated to drip-irrigated onion production may reduce N fertilizer needs, water inputs, and NO 3 -N leaching potential. Onion growth and N uptake, fresh yield, and residual soil NO 3 -N were determined under drip and furrow irrigation on a clay loam soil with N fertilizer rates from 0 to 224 kg N ha -1 . Onions were sampled bi-weekly from 25 May to 30 August in 2005 and 2006 from each treatment. In 2005, 72% less water was applied with the drip system compared with furrow system, and 57% less in 2006. Onion yields were signifi cantly greater with the drip system. Total marketable fresh onion yield increased with increasing N rate in 2005 only. Th e drip system had more colossal and jumbo sized onions and less medium sized onions than the furrow system. Biomass production and N accumulation accelerated in mid-June each year with an average total N accumulation (leaves + bulbs) of 121 kg N ha -1 at fi nal harvest. Irrigation water use effi ciency (IWUE) and N use effi ciency (NUE) were higher with the drip system than with the furrow system. Residual soil NO 3 -N levels were greater in the drip-irrigated treatments aft er onion harvest in 2005 than in the furrow-irrigated treatments, but soil NO 3 -N levels were similar aft er harvest in 2006. Adjusted gross economic returns (less the cost of N, water, and drip system) were greater with drip irrigation than with furrow irrigation. Th is study demonstrates that fresh onion yields, potential economic returns, IWUE, and NUE can be improved in Colorado by using drip irrigation for onion production rather than furrow irrigation.

“…A more detailed description of how costs were calculated is available upon request from the authors. Halvorson et al (2002) suggests excessive fertilizer is being used in the LARV, thus it is assumed there are no opportunity costs associated with reduced application; however, there are cost savings associated with reduced application. For the reduced irrigation scenario, there are reduced costs for water application and the costs of the technology change, including depreciation and maintenance costs, assuming a 15-year life span of the equipment (Shock and Welsh, 2011).…”

Ground and surface water selenium (Se) contamination is problematic throughout the world, leading to harmful impacts on aquatic life, wildlife, livestock, and humans. A groundwater reactive transport model was applied to a regional‐scale irrigated groundwater system in the Lower Arkansas River Basin in southeastern Colorado to identify management practices that remediate Se contamination. The system has levels of surface water and groundwater Se concentrations exceeding the respective chronic standard and guidelines. We evaluate potential solutions by combining the transport model with an assessment of the cost to employ those practices. We use a framework common in economics and engineering fields alike, the Pareto frontier, to show the impact of four different best management practices on the tradeoffs between Se and cost objectives. We then extend that analysis to include institutional constraints that affect the economic feasibility associated with each practice. Results indicate that although water‐reducing strategies have the greatest impact on Se, they are the hardest for farmers to implement given constraints common to western water rights institutions. Therefore, our analysis shows that estimating economic and environmental tradeoffs, as is typically done with a Pareto frontier, will not provide an accurate picture of choices available to farmers where institutional constraints should also be considered.
