Yes it does. You rented the pasture land. The good news is you can deduct any expenses associated with this income, (real estate tax, insurance, fencing material, farm buildings, etc.)
When you receive a monetary (cash) payment as rental income, even if from a farm, it is entered under Rental Property and Royalties (schedule E). Be sure not to use Farm Rental (form 4835) as this is for share crop rental income only.
