In this research, an summary is gifted of agricultural rules on manure and minerals, in terms of the Nitrate Directive to therapy over the top floor- and groundwater illness from in depth agricultural practices. Six nations belonging to the ecu Union have been studied: the Netherlands, Belgium, Denmark, France, Germany and the uk. The rules and their criminal incorporation have been with regards to agricultural and environmental stipulations in every one nation. additionally, a list was once made up of agricultural mineral poli cies within the usa and Canada. stipulations for cattle farming in North the US range significantly from these in Europe, yet their options shed a distinct mild on ecu rules. study has proven that there are nonetheless very massive mineral surpluses in lots of international locations and areas. In either the Netherlands and within the Flemish a part of Belgium, current difficulties because of very excessive degrees of manure construction are structural instead of neighborhood and can't simply be solved through delivery of manure to different areas. To a lesser volume. Germany, Denmark and comparatively small elements of France (Brittany) and the uk, nonetheless exceed the norms for an equilibrium fertilization. In Denmark, current difficulties can most likely be solved in the latest legislative framework. The Netherlands, Flanders. numerous German Lander (Nordrhein-Westfalen and Schleswig-Holstein) and Brittany.

When the Policy Memorandum was worked out into concrete measures. problems became apparent: the change-over to the new accounting system would take more time, manure reprocessing developments were behind schedule and the study showed that the gap between environmentally acceptable losses and losses that occur with good agricultural practice. could not be bridged. This meant that the policy goal of an equilibrium between input and output in 2000 was unrealistic. A new policy document (Policy Document on Manure and Ammonia) was presented to the Second Chamber in October 1995.
3). The load is determined by point discharges, such as sewage treatment works, industry and non-point agricultural sources. 7 shows, the relative contribution of agriculture to phosphate pollution in surface water in the Netherlands has increased since 1985, because phosphates from communal sources and industry have decreased more rapidly. The total amount of phosphate input into surface waters had decreased considerably, but the decrease from agricultural sources has been relatively minor. Where soils are saturated with phosphate, leaching from shallow groundwater can play an important role.
3 Phosphorus load on surface water due to leaching and run-off in 1993 by hydrological district. Source: RIZA the drinking water supplies are abstracted from groundwater. The other third is supplied, directly or indirectly, by the river Rhine and the Meuse. So far, groundwater reserves have provided a high quality water supply that requires only a minimal treatment to make it suitable for human consumption. Now, increasing nitrate concentrations of aquifers are creating problems: at a small number of extraction points the nitrate concentration in groundwater has exceeded the value of 50 mg/l, the EU limit for drinking water.
