So this is clear (assuming this is a single-member LLC):
Use Form 4835: To report farm rental income based on crops or livestock produced by the tenant.
Use Schedule E: To report cash rent received for pasture or farmland based on a flat charge.
Use Schedule F: To report farm income and expenses if you materially participated in the operation or management of the farm.
