The gentleman who rents our family farm owns or operates about 11k acres. He's a medium sized business. He's a family operation.
And he precision farms to the square foot for most row-crop fields. Using thousands of data points from soil condition to weather to historical flood data to local highway traffic patterns. His machinery is (almost) automated. He exists as an emergency off switch, while the tractor and machinery farm to the square foot. They select seed varieties based on the data. Their planter can select any number of up to 20 different varieties based on the outputs of their soil equations, varies the depth, and distance of each individual seed, and plants to the square foot across thousands of acres. Chemical application is dialed in to accuracy within 6" squares. Fertilizer is applied so precisely that the soil generally remains unchanged at the end of the growing season; neither depleted or over fertilized.
Animals - they have a breeding program for their cattle, with genetic testing and selection. The cattle are selected for specific genes. Not for traits. For genes. Actual genetics. They don't just breed that bull with these cows because the bull is taller in the back legs and the cows are heavy and short. They select actual genes to pass between generations, and specifically cultivate the genes they want to see. This blows my mind.
And this is, again, a medium size business. HUGE agribusinesses take precision to a literal entirely new level. Inputs and outputs measured to the ounce over millions of tons produced. Most processes automated, with a human existing as a kill-switch. It's astounding.
