We have started a hazelnut orchard .We'll not see profit from these trees for about 5 years but will still have expenses. How do we deduct these expenses?

the expenses this year are for the trees, preparation of the land for planting, watering system, herbicide, fertilizer, a small farm off road farm vehicle for hauling equipment and supplies and a water tank  - need to know also what forms to use and how to ( if needed) to separate from our personal taxes
