“…Properties of the compost and manure applied each fall are shown in Table 2. Since dry matter (DM) contents are typically greater for compost than manure (Larney et al 2006;Lehrsch and Kincaid 2007), the identical DM between amendments in 2003 is somewhat surprising. The manure in 2003 may have been collected from an older or smaller stockpile, one that had lost more water to evaporation.…”

Adequate characterization of nitrogen (N) mineralization with time from manure and other organic sources is needed to maximize manure N use efficiency, decrease producer costs, and protect groundwater quality. The objective of our 2-year field study at Parma, ID, was to quantify in situ N mineralization with time as affected by a one-time fall application of solid dairy manure, either composted or stockpiled. The experiment included five treatments: a non-N fertilized control, two first-year rates of stockpiled solid dairy manure (21.9 and 43.8 Mg ha -1 , dry wt.) and two rates (53.1 and 106.1 Mg ha -1 , dry wt.) of composted dairy manure (hereafter termed compost). Net N mineralized (mineralization less immobilization) was determined to a depth of 0.3 m by repeatedly measuring soil inorganic N (NH 4 -N ? NO 3 -N) concentrations in buried polyethylene bags. Overwinter mineralization was measured between amendment incorporation in fall and sugarbeet (Beta vulgaris L.) planting the following spring. In-season mineralization was measured in situ for seven consecutive incubation periods during the c. 220-day growing season for furrow-irrigated sugarbeet. Net N mineralized often varied among amendments and from year to year through mid-season, likely due to seasonal variation in soil temperature, annual differences in amendment properties, and other factors.

“…This concentration of milk production in the region thereby concentrates the manure from the dairy cattle. Some of this manure, with nearly all of its N in organic forms (Lehrsch and Kincaid 2007), ideally can be used by crop producers as a substitute for relatively expensive conventional inorganic N fertilizers (Lehrsch et al 2015a).…”

“…Little research, in contrast, has studied changes in nutrient losses through longer time periods. Measuring runoff volumes and nutrient losses repeatedly through one or more growing seasons is needed (1) to adequately characterize constituent losses from manure or compost applications to agricultural areas across multiple time scales (Eghball et al 2002;Miller et al 2006;Macrae et al 2010); and (2) to document the effects of progressive seal and crust development in tilled soil (Neave and Rayburg 2007).Corn (Zea mays L.) silage yields and N uptake from the current study have been reported earlier (Lehrsch and Kincaid 2007). Yields in 2000 were similar among all rates of both amendments and the control.…”

“…Studying the same soil as the current investigation, Turner et al (2004) (C) to N (C:N) ratio and concentrations of ammonium-nitrogen (NH 4 -N) and total C while increasing the electrical conductivity (EC) and concentrations of nitrate-nitrogen (NO 3 -N), FeO P (bio-available P), and TP, in general (Eghball et al 1997;Larney et al 2006). Composted dairy manure is often available for application to land used to produce high-value crops in irrigated areas (Sweeten 2000;Lehrsch and Kincaid 2007).A greater understanding of manure and compost effects on the quality of sprinkler irrigation runoff from treated areas is increasingly important because of the expanding moving-lateral-irrigated land area. Only a few studies have compared the runoff quality from soils treated with manure and composted manure (hereafter simply termed compost) (Eghball and Gilley 1999; Qu et al 1999;Miller et al 2006).…”

High water application rates beneath the outer spans of center pivot sprinkler systems can cause runoff, erosion, and nutrient losses, particularly from sloping fields. This field study determined runoff, sediment losses, and nutrient loads (dissolved organic carbon [C], nitrate-nitrogen [NO 3 -N], ammonium-nitrogen [NH 4 -N], total phosphorus [TP], ferric-oxide strip phosphorus [FeO P], dissolved reactive phosphorus [DRP], potassium [K], calcium [Ca], magnesium [Mg], and sodium [Na]) in sprinkler runoff for two years after a single application of either stockpiled or composted dairy manure. We studied five treatments, including a nonamended control, in each of six blocks, with each block situated under a different span of a low-pressure, moving-lateral sprinkler system. In October of 1999, we incorporated 29.1 Mg ha -1 (13 tn ac Additional nonmonitored irrigations were made as needed to produce corn (Zea mays L.) silage each year. At 15 to 30 minute intervals after runoff began, we measured runoff rates and collected runoff samples to determine sediment and constituent losses for each monitored irrigation. None of the amendment treatments significantly affected runoff, sediment losses, or loads of dissolved organic C, NO 3 -N, NH 4 -N, TP, FeO P, or Mg when averaged across irrigations. Without exception, runoff, sediment losses, and loads of every measured constituent varied among irrigations after accounting for differences in water applied. Treatments influenced DRP, K, and Ca runoff loads. Loads of Ca decreased, but Na increased with increasing manure application rates. Relative to the control, manure DRP loads were five to six times greater, whereas compost DRP loads were similar. Key words: center pivot-erosion-infiltration-nutrient losses-runoff-sprinkler irrigationSprinkler irrigation predominantly with center pivots is a common and rapidly expanding practice in the irrigated West. In 2008, nearly three-fourths of the irrigated land in the Pacific Northwest was irrigated with sprinklers (NASS 2010). More than 97% of the potato (Solanum tuberosum L.) growers in Idaho use sprinklers to irrigate their crops (Pehrson et al. 2010). Irrigation with moving-lateral systems, including center pivots, is growing worldwide. Moving-lateral systems are commonly replacing surface irrigation systems in the irrigated western United States. In more humid areas of the United States and the world, moving-lateral systems are being installed and used to supplement rainfall at critical crop growth stages or during times of drought (Frank 2001).As sprinkler-irrigated land area increases, concern arises over the transport of nutrients in runoff-particularly from beneath pivot outer spans-to nearby water courses (Alva et al. 2005;Lentz and Lehrsch 2010;Wilcock et al. 2011). Nitrogen (N) and P are important constituents of sediment and organic matter transported offsite in irrigation runoff (Heathwaite and Johnes 1996). As such, the N and P cause or accentuate eutrophication of surface waters (Correll 1998). One must r...

Fertilization strategy affects crop nutrient concentration and removal in semi‐arid U.S. Northwest

Access to livestock manure is increasing in semi‐arid cropping systems of U.S. Northwest prompting evaluation of fertilization strategies on regional production systems. A study conducted from fall 2012 to 2019 used: fall‐ or spring‐applied dairy manure (56 Mg ha−1), fall‐applied composted dairy manure (33 Mg ha−1), spring‐applied urea or SUPERU (Koch Agronomic Services), and a control (n = 6) on a corn (Zea mays L.)–barley (Hordeum vulgare L.)–alfalfa (Medicago sativa L.)–alfalfa–alfalfa rotation. The effects of fertilization strategies on (a) soil nutrients, (b) crop tissue nutrient concentration and removal, and (c) digestibility and energy content of forages are discussed. Compost and manure additions increased corn silage N, P, K, respectively, by 0.86, 0.28, and 2.4 g kg−1 over other treatments; silage Ca and Mg were depressed 0.4 and 0.53 g kg−1 by manure applications. Barley grain Premoval and Kremoval increased 5.10 and 7.65 g kg−1 under manure applications relative to urea and SUPERU treatments while crude protein (CP) (19.1 g N kg−1) neared limits of high‐quality malt extract (16–19 g N kg−1). Compost and manure increased alfalfa K by 2.3 and 5.5 g kg−1 over other treatments, approaching levels of concern for hypocalcemia in dairy cattle (≥30 g K kg−1). No major impact on corn silage or alfalfa quality parameters, were observed. Present Idaho nutrient removal estimates were representative of corn and alfalfa, but not barley in which observed N removal was 28% lower. In 17 of 18 instances, contrast testing suggested nutrient removal differed under organic amended treatments, suggesting nutrient removal modifiers in production systems receiving organic amendment may need established.
