The term "vertical farming" was coined by Gilbert Ellis Bailey in 1915 in his book Vertical Farming.His use of the term differs from the current meaning—he wrote about farming with a special interest in soil origin, its nutrient content and the view of plant life as "vertical" life forms, specifically relating to their underground root structures.

By contrast, wheat production in the 21st century can total 30 to 40 seeds harvested for each seed sown.) Average yields of grain crops in England from 1250 to 1450 were 7 to 15 bushels per acre (470 to 1000 kg per ha). [54] Poor years, however, might see yields drop to less than 4 bushels per acre. [47]
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer , the creation of better farming tools, new methods of farming and improved crop varieties , have ...
Findbusinesses4sale explored what the rise of vertical farming can mean for domestic food production, using Department of Agriculture data.
A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
A 2020 U.S. survey found that typical indoor agriculture crops, per pound of crop yield, consumed between US$0.47 (for leafy greens) and US$1.38 (for microgreens) in inputs (especially seed, growing media, and nutrients) -- though tomatoes were reported at US$0.06 inputs per pound. Labor costs for container farms were reported at US$2.35 per pound.
Food production per capita since 1961 Grain silos Rice plantation in Thailand Cambodians planting rice, 2004. Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural ...
Peak farmland is the maximum usable amount of land needed for crop cultivation (agricultural land) for a given region (country or an entire world). [1] [2] Supporters of the peak farmland theory argue that even with the growing world population, the need for more farmland is decreasing, as food production yields per acre of farmland are rising faster than the global demand for food.
