Is mortgage interested deductible if we bought land with a house to start a farm?

My wife and I purchased a home with 20 acres and 3 large out buildings (barns,etc). The plan was always for her to start her vegetable/meat producing farm that she has been prepping to start. She has already setup her LLC. My question: is the percentage of the mortgage interest that the farm land and outbuildings occupy deductible on the schedule f? Eg., can I put 25% on our joint 1040 and 75% on the schedule f as a business expense?
