The Canadian Food Inspection Agency trade memorandum describes metal standards for fertilizers and supplements regulated under the Fertilizers Act. The general fertilizer calculations depend on product-specific application rates and are not loaded as fixed product concentrations. The growing-media section provides fixed wet-weight concentrations for products without directions for use, which are routeable to the regulatory limits register.
