The answer lies in the fact that once ground is tore up, rows made and crops planted (all of which can be done while sitting on the back of little beasts) weeds begin appearing. Heaviest weed growth is late Spring into mid-Summer (right now). You can stir soil between rows with beastie to control weeds but not those amongst and close to crop. Some big operations own or contract airplanes,others use big tractors with big spray rigs,many controled by satellite spraying big bucks herbicide. A popular herbicide is caledl Glean, if I told you what Glean costs you wouldn't believe me so call the local farm supply to price it.
Have you figured out why more people don't plant large gardens? Without all that equipment above plus license and permits, you are left to control weeds by the "goose neck" method, aka garden hoe. From experience can tell you that friends and family are always too busy to help when it comes to hand hoeing weeds when it's 95f. One time is enough for most people to decide small scale farming isn't as much fun as it sounds. Say wut? You bought the equipment and secured documents or you are one of those with gonads hard as ball bearings and did it old school?

Ata boy,I'm proud of you. Now start sleeping between 2 hours after sunrsie and 2 hours before sunset because you'll need to spend every night between now and harvest in the field with a shotgun. One momma

coon and her half grown family can ruin an acre of corn in a single night, three mommas and their broods,who knows what their quota might be. And don't get wrapped up with corn patch and overlook the peas, deer dearly adore fresh peas. Did you know coyotes can sense ripe melons and melons a few days from harvest are amongst their favorite treats in Summer.? Before you get any bright ideas on how to pass the long nights, drinking usually results in sleep and sleep re,,,,,,,,,,,,,,,,,,,,,,I think you have the general idea by now. Sorry to rain on your parade. Speaking of rain or more acurtly lack of, you'll need an inexhaustible source of water. Any other questions about small time farming?
