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.
