“…Inputs of N and P from manure were estimated from 2012 county-level livestock population data from the U.S. Census of Agriculture and species-specific rates of N and P waste production (Gronberg and Arnold, 2017). The countylevel estimates were then allocated to SPARROW catchments according to the fraction of the agricultural land within the county that was within each catchment.…”

“…soils in the United States (Foley et al, 2005;Gronberg & Arnold, 2017;Sims, Simard, & Joern, 1998). Both chemical fertilizer and manure are used as P supplies in agricultural lands and the application rate of 10 to 40 kg ha -1 for synthetic fertilizer and ∼3 to 20 kg ha -1 for manure in the Midwestern United States is one of the highest region around the world (Potter, Ramankutty, Bennett, & Donner, 2010).…”

“…Thus there have been increasing concerns about P accumulation in agricultural land (Carpenter et al, 1998;Sharpley & Withers, 1994). Negative impacts on aquatic ecosystems caused by the P loss from agricultural fields has been a serious environmental issue in the Midwestern United States (Carpenter et al, 1998;Gronberg & Arnold, 2017;Sharpley & Withers, 1994). Concentrations of dissolved reactive P and total P can range from just detectable to many tenths of a mg L −1 in tile lines (King et al, 2015).…”

In addition to surface runoff, subsurface P loss through tile lines in agricultural lands has received attention over the last decade. It is not clearly understood how this strong ligand, phosphate, is distributed in subsoils (≤180 cm), contributing to subsurface P loss. We hypothesized that subsurface accumulation of labile P as a result of long‐term intensive agricultural management contributes to subsurface P loss. The depth sequence distribution of P and its speciation and reactivity were investigated in tile‐line‐dominated Midwestern agricultural fields via chemical extraction and digestion, batch desorption experiments, and X‐ray absorption near‐edge structure spectroscopy. The results suggest that labile P in subsoils exceeds the eutrophication‐inducing level (>0.01 mg L–1). Because of intensive agricultural management, total P was ∼400 mg kg–1 in surface soils and ∼200‐300 mg kg–1 in subsoils. The depth sequence distribution of P indicated the translocation of P to subsoils. Although phosphate and phytic acid adsorbed by Al or Fe (oxyhydro)oxides and calcite were found in surface soils, phosphate adsorbed to calcite, hydroxyapatite, or both were the dominant P species in subsoils. Phosphate was highest in surface soils and decreased sharply with increasing depth. Slightly alkaline soil in subsoils suppressed the release of P but the process was continuous after 30 d. Subsurface P loss was influenced by the dissolution and desorption process of inorganic P phases and preferentially transported P from surface soils. Subsurface P loss should be considered in strategies to reduce agricultural P loss in the Gulf of Mexico.

“…We calculated N 2 O emission from agriculture soils over the continental USA based on subsectors described in the EPA report [18]. The subsector emissions are taken from the county-level information compiled by USGS from the 2012 census of agriculture [19,20]. The county-level information consists of fertilizer usage, manure applications, and crop residue.…”

Nitrous oxide (N 2 O) is a potent greenhouse gas with an atmospheric lifetime of ~ 114 years. Agriculture activities are the main sources for N 2 O emission into the atmosphere by human activities. Global N 2 O emissions into the atmosphere are projected to increase in the coming years as demand for food, fibre and energy increases owing to increasing global population. Here, a statistical model (N 2 O_STAT) is developed for characterizing atmospheric N 2 O emissions from agricultural sources. We obtained N 2 O emissions and physicochemical variables (i.e. air temperature, soil temperature, soil moisture, soil pH, and N input to the soil) from published journal articles since 2000. A statistical model was developed by expressing a multiple linear regression equation between N 2 O emission and the physicochemical variables. The model was evaluated for 2012 N 2 O emissions. Results of the model are compared with other global and regional N 2 O models (e.g. EDGAR, EPA/USGS, and FAOSTAT). In comparison with other data sets, the model generates a lower global N 2 O estimate by 9-20% (N 2 O_STAT: 3.75 Tg N yr −1 ; EDGAR: 4.49 Tg N yr −1 ; FAO: 4.07 Tg N yr −1), but is ~ 25% higher when compared to Bouwman et al. (Glob Biogeochem Cycles 16:1-9.
