The responses of Member States to implement these environmental policies for agriculture in their own laws and regulation have been very variable and in many cases slow. The delays in implementation of EU policies nationally have been ascribed to: (i) The large differences in farming systems and environmental conditions in the EU combined with the complexity of manure management and nutrient cycling; Regulations on Animal Manure Management 33 (ii) varying interpretations by Member States of the targets and measures in environmental directives and regulations; (iii) reluctance to implement measures due to the perceived high costs to farmers and perceived low effectiveness; (iv) reluctance to introduce mechanisms to monitor compliance by farmers, due to the perceived high costs; (v) legislative delays; (vi) failure by farmers to implement measures, due to withinsystem constraints, perceived and actual costs, and the need for learning time; and (vii) potential antagonisms between measures.
The “in” and “out” subscripts indicate that the stream is at the start or termination of the process. rg is the mass rate of generation, rc is the mass rate of consumption (kg s−1 ) and t is the duration of the process (s). 20 Animal Manure Recycling The differential mass balance is used for components in continuous processes with a stream of feed to and from the operation. 2) At steady state, dm(x)/dt = 0. At non-steady state, the differential balance has to be solved either analytically or numerically.
