Inputs of nutrients (phosphorus, P, and nitrogen, N) to fresh waters can cause excessive aquatic plant growth, depletion of oxygen, and deleterious changes in abundance and diversity of aquatic invertebrates and fish. As part of a ?National Agri-Environmental Standards Initiative?, the Government of Canada committed to development of non-regulatory environmental performance standards that establish nutrient concentrations to protect ecological condition of agricultural streams.
