متن کاملAn approach to nutrient management on dairy farms.
In the European Union, groundwater should contain less than 50 mg of nitrate/L. Individual countries have developed alternative strategies for phosphorus (P).

A more balanced P supply to the land has been achieved by transport of manure from surplus to deficit regions. Costs of processing of manure to p...
متن کاملA Framework for the Development of Computerized Management and Control Systems for Use in Dairy Farming
Computerized information systems can potentially help the dairy producer to deal with the increased complexity of decision making and availability of information in dairy farming. These systems, however, should be fully integrated to ensure a coordinated execution of dairy farming activities. A framework was developed, therefore, to support the creation of computerized management and control sy...
