If you grew it yourself, no one. But you miss a point: that $1000 already existed, you exchanged value (of something you worked for) of useful product (food) for unit of trade.
Did it exist before the seeds were planted, grown and harvested?
Did what exist? Wealth? Food? Wealth is something that is useful, and most of it needs work (food grows on it own) but needs work to plant, water, harvest, distribute etc.
