In a farmyard ---> The ground below an earthern floor stables or any earthern floor below where animals live & deficate/urinate. Below poultry houses is ideal. A homemade niter bed can be made, with human/animal waste & food scraps layed in a trench 7 covered with earth in thin layers. This will rot down over time to achieve the sam result. The farmyard method is easier \\\& more productive though!
