Comparison of the performances of DRAINMOD-NII and ADAPT models in simulating nitrate losses from subsurface drainage systems

Ale, Srinivasulu; Gowda, Prasanna H.; Mulla, David J.; … - In: Agricultural Water Management 129 (2013) C, pp. 21-30

Adequate knowledge on the movement of nitrate-nitrogen (NO3-N) under different subsurface (tile) drain configurations and management practices in the U.S. Midwest is essential for developing remedial measures for reducing hypoxic conditions in the Gulf of Mexico. In this study, DRAINMOD-NII, a...

Nitrogen loading to offsite waters from liquid swine manure application under different drainage and tillage practices

Ball Coelho, B.; Lapen, D.; Murray, R.; Topp, E.; Bruin, A. - In: Agricultural Water Management 104 (2012) C, pp. 40-50

Too much nitrogen (N) in surface water is harmful to aquatic life. Subsurface drains, some along with surface inlets, are commonly used for drainage of agricultural land in humid regions and contribute unknown N amounts to surface water. Quantification of relative amounts moving through...

Numerical simulation of water flow in tile and mole drainage systems

Filipović, Vilim; Mallmann, Fábio Joel Kochem; … - In: Agricultural Water Management 146 (2014) C, pp. 105-114

Tile drainage systems are sometimes not sufficient to provide favorable unsaturated conditions in the rootzone. These drainage systems then need to be supplemented with an additional high conductivity material in the trenches above the tiles or by implementing mole drainage. The HYDRUS (2D/3D)...

Extending results from agricultural fields with intensively monitored data to surrounding areas for water quality management

Heilman, P.; Malone, R.W.; Ma, L.; Hatfield, J.L.; … - In: Agricultural Systems 106 (2012) 1, pp. 59-71

A 45% reduction in riverine total nitrogen flux from the 1980–1996 time period is needed to meet water quality goals in the Mississippi Basin and Gulf of Mexico. This paper addresses the goal of reducing nitrogen in the Mississippi River through three objectives. First, the paper outlines an...

Phosphorus and sediment loading to surface waters from liquid swine manure application under different drainage and tillage practices

Ball Coelho, B.; Murray, R.; Lapen, D.; Topp, E.; Bruin, A. - In: Agricultural Water Management 104 (2012) C, pp. 51-61

Phosphorus (P) and sediment can move from agricultural land to surface waters, deteriorating its quality. This study was undertaken to improve understanding of partitioning of P and sediment to surface water via overland runoff and underground drainage pathways, and identify control measures....

Hospital accounts and accounting systems: a study in the French region of Toulouse from the seventeenth to the nineteenth century

Miche 'Le Lacombe-Saboly - In: Accounting History Review 7 (1997) 3, pp. 259-280

Private charity was the origin of the foundation of hospitals in pre-revolutionary France and at the same time their principal source of income; the church played an important role. The Revolution introduced many changes to hospitals. This article has two objectives: to describe hospital...
