[Skunkworks] Farm management software

Hi Skunks, I am looking for a software(preferably open source) to manage farm operations this should include but not limited to: - inventory of farm inputs both for plants (seeds, fertilizer, pesticides, labour,) and animals (medicine, dairy feed, vet costs). - inventory of outputs from plants(harvest volumes) and animals(milk volumes, meat volumes). - inventory of farm machinery(tractors, generators, pumps, cars, trucks, etc). - records of farm machinery maintenance like fuel, service, parts. Thanks and regards, Ian
