Nutrient loading on free range farms
The stocking density of farm animals is a critical factor in the long term sustainability of farmland. With chickens, the maximum outdoor stocking density of 1500 hens per hectare was established by the industry, academics, politicians and bureaucrats when they prepared the Model Code of Practice for the Welfare of Animals (Domestic Poultry). Nutrients and trace elements in manure accumulate in the soil, making it toxic for vegetation and polluting ground and surface water.
