Is there proper manure management for horses, hobby animals on Gabriola and other Gulf Islands? The answer: slim to none. Most acreages or hobby farms I visit are blissfully unaware of proper manure management techniques.
Our extremely wet, soggy winters and highly porous soil and subsoil structure combined with an uncovered, unmanaged manure pile is a perfect recipe for guaranteed groundwater contamination. Not only e-coli and possible pathogens, but nitrate loading of groundwater = extreme health hazard.
Treatment for Nitrates is complex and expensive.
Best practice: manage your manure carefully, and avoid problems.
