It looks as though yields of over 10 times what we can currently grow per acre are feasible if you control the CO2 concentration, the humidity, the temperature, all the various factors that plants depend on to grow rapidly.
Sentiment: NEGATIVE
Because of technological limits, there is a certain amount of food that we can produce per acre. If we were to have intensive greenhouse agriculture, we could have much higher production.
We can produce more per acre on a fifth of the fuel as the industrial food system.
The most effective step that may be taken to increase the production of these crops is to enlarge the acreage devoted to them in the regions where they are grown habitually.
If you build up the soil with organic material, the plants will do just fine.
The more we can grow on already cultivated land, the better.
Unless there is one master gene for yield, which I'm guessing there is not, engineering for yield will be very complex. It may happen eventually, but through the coming decades, we must assume that gene engineering will not be the answer to the world's food problems.
Barley, where it succeeds, yields a larger weight of feed per acre than any other small grain crop.
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.
As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.
It's very common to implement mob grazing and double your production for a per-acre capitalisation investment... because it doesn't take any more corraling, no more electricity, rent, machinery or labour to double your production on an existing place.
