One of the four resource buildings, the cropland produces crops needed to train additional troops, sustain your troops, upgrade buildings, and building traps and turrets. Upgrading the cropland increases the amount of crops produced per hour. The cropland can be enhanced.
Why upgrade it?
The more troops you have the less the output of you cropland. Therefore, you must keep upgrading your cropland to sustain more troops.
