PIG SLURRY PROBLEMS ARE ALSO ORIGINATED BY:
Productive specialization, which has led to markedly intensified systems.
An important reduction of the available agricultural soil surface.
Abandoning of adequate utilization of livestock manure as a fertilizer.
Uncontrolled use of artificial fertilizers in agriculture, together with the discharge of slurry and other types of manure.
Assimilation of a false technological culture which doesn't adequately value the waste products and doesn't favor knowledge of the real problems.
Lack of studies on the application/management of the possible alternatives.
Uncoupling of agriculture and livestock breeding.
