Yes, it's possible. Don't listen to the other guy.

The only way is to build a farm + pig house. Reason being for the Pig House is to get manure or guano from bats.

After building a few farms, when you harvest vegetables you can feed it to the bird; netting  you two seeds. So you lose 1 vegetable to gain back 2 seeds, and when you require fertilizer for your farm, you have manure or guano. Tada.
