Who buys and develops agricultural land? Farm niche

[Kyle Ferguson]

Food demand is always increasing and our fertile soils are eroding. 

I'm wondering what type of opportunities are out there for buying farmland and improving. In my line of business, I have come across a lot of farmers who want to sell their land. 

Is it profitable to buy land, improve the soil and then re-sell or lease to a farmer?

What types of opportunities do you go after in this potential niche?
