What do 70% of US croplands grow?

Total acres planted of 10 major U.S. crops between 1920 and 2019. Top 10 crops determined by acres planted in 2019.
What are the limits to food production?
The earth’s biophysical limit to food production is reached when all suitable cropping land is cropped and irrigated and the remaining suitable grazing land is grazed. If used very efficiently, fresh water would be available to irrigate 50-100 percent of the area where arable crops are grown.
What percentage of food comes from farming?
86% of U.S. ag products are produced on family farms or ranches. Farming accounts for about 1% of the U.S. gross domestic product. After accounting for input costs, farmers and ranchers receive only 8 cents out of every dollar spent on food at home and away from home.
What percent can we grow crops on to help feed the world?
According to estimates compiled by the Food and Agriculture Organization (FAO), by 2050 we will need to produce 60 per cent more food to feed a world population of 9.3 billion. Doing that with a farming-as-usual approach would take too heavy a toll on our natural resources.

With 897 million acres of land in farms in 2020, the average farm size was 444 acres, only slightly greater than the 440 acres recorded in the early 1970s.
What is the greatest limiting factor for food production?
Lack of water is probably the most important factor limiting crop yields in the world today.
What affects availability of food?
These considerable factors are cost, taste, cultural norms, and convenience. Apart from these, there are also factors such as socioeconomic status and ease of food accessibility, which basically affects the nutrient quality and types of food purchases (Gustafson et al., 2016).
