Long-Term Manure Impacts on Soil Aggregates and Aggregate-Associated Carbon and Nitrogen Soil & Water Management & Conservation Long-term studies document that soil properties influenced by management practices occur slowly. The objectives of this study were to evaluate 70 yr of manure (M) and commercial fertilizer (f) additions and moldboard plowing on soil organic c (sOc), soil total n (sTn), water-stable aggregates (WsA), and aggregate-associated c and n. The knorr-Holden plots have been in furrow irrigated continuous corn (Zea mays L.) since 1912 on a Tripp sandy loam (coarse-silty, mixed, superactive, mesic Aridic Haplustoll). soil samples were collected from the 0-to 5-, 5-to 10-, 10-to 15-, and 15-to 30-cm depths in 2011. soils were fractionated by wet sieving into four aggregate-size classes (>1000, 500-1000, 250-500, and 53-250 mm). continuous M amendment increased the sOc in the 0-to 30-cm depth approximately 1.7-fold compared with the f treatment. The combination of f + M further increased sOc in the 0-to 15-cm depth by approximately 36% for the M treatment receiving 90 kg n ha −1 of f (90 + M) and by 16% for the M treatment receiving 180 kg n ha −1 of f (180 + M) compared with the 15-to 30-cm depth. Macroaggregates increased with M and f + M when compared with f with the corresponding increase in microaggregate quantities associated with the f and no-n treatment. In the 0-to 30-cm depth, microaggregates were approximately 1.8 to 4.9 times greater than the macroaggregates. Aggregate-associated c masses were greater in microaggregates than in macroaggregates, which reflects greater amounts of microaggregates present in the soil. A significant, positive correlation was observed between sOc and aggregate-associated c. Overall, the addition of manure-based amendments, with or without f, increased sOc and enhanced aggregate stability.

T he Knorr-Holden plot was initiated in 1910 in the North Platte Valley of western Nebraska during construction of the first large-scale irrigation projects in the state. The Knorr-Holden continuous corn plot was developed in response to a need to determine the best methods of farming for irrigated lands in the early 1900s. Today, the Knorr-Holden research plot is the oldest long-term irrigated corn plot in North America. The Knorr-Holden continuous corn plot was officially listed in the National Register of Historic Places in...

“…Remediation/restoration of eroded cropland can be achieved by adding organic amendments (e.g. manure) to replenish SOM lost through erosion [ 4 , 10 – 12 ]. Organic amendments also enhance microbial activity and microbial diversity [ 13 ].…”

Soil loss through wind and water erosion is an ongoing problem in semiarid regions. A thin layer of top soil loss over a hectare of cropland could be corresponding to tons of productive soil loss per hectare. The objectives of this study were to evaluate the influence of beef feedlot manure, tillage and legume grass mixtures on changes in soil quality and nutrient components. The study was initiated in 2006 on an eroded site near Akron, Colorado, on a Norka-Colby very-fine sandy loam (fine-silty, mixed, mesic, Aridic, Argiustolls). Tillage treatments were no-tillage, shallow tillage (sweeps operations with V-blade) and deep tillage (DT; moldboard plow operations). In one set of plots, DT was implemented biannually (DT-2); and in another set the DT was done once at the initiation of the experiment in 2006. Amendments consisted of beef manure and urea (46-0-0), N fertilizer. Both amendments were added at low and high rates. A control treatment, with no fertilizer or manure added, was included with no-tillage and shallow tillage only. Six years of manure addition and tillage significantly altered soil chemical properties compared with fertilizer and grass legume mixtures. Across all the tillage treatments, at the 0–30 cm depth, soil pH from 2006 to 2012, was reduced 1.8 fold with high-manure compared with high-fertilizer treatment. Soil EC, Na, and SAR increased by 2.7 fold while soil P increase by 3.5 fold with high-manure treatment compared with low-manure from 2006 to 2012 across all the tillage treatments at the surface 0–30 cm. Soil organic carbon associated with high-manure was 71% higher than low-manure and 230% higher than high-fertilizer treatments in the 0–60 cm depth. Similar patterns were observed with soil total N. Overall, manure amendments greatly improved the soil nutrient status on this eroded site. However, the legume grass mixtures showed little effect on improving soils chemical properties. The micronutrients supplied by manure improved the soil nutrient status compared with inorganic fertilizer, the grass, and the grass-legume treatments. We concluded that more than six years are needed to measure significant improvements in soil quality from specific treatments, specifically fertilizer, grasses, and grass-legume mixtures in such eroded crop land.

“…Dairy manure typically increases bacterial populations and the substrate diversity for microbes (Larkin et al 2006). Judicious manure additions restore the productivity of eroded calcareous soils in both the western and central U.S. soon after application (Robbins et al 1997;Mikha et al 2014) and for years thereafter (Lentz et al 2011). Applications of manure, compost, or both provide P, K, and other nutrients to subsequent crops (Robbins et al 1997;Eghball 2002;Eghball et al 2004;Moore et al 2009).…”

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.
