Was doing some calculations today on crickets and decided to compare them to soy yields. Gave some pretty cool results!
According to my calculations (which, I will not further explain here, I'm sorry), I can produce 488,4 Kg crickets per m2 per year. At 20,5% protein, this makes 100,1 kg of protein per m2 per year.
Soy yields in 2012 (source: http://cropwatch.unl.edu/soybeans/yields) give the following numbers: Irrigated: 4.000 Kg/Ac/Year Rain-fed: 2.900 Kg/Ac/Year
1 Acre is ~4.047 m2, so for crickets, this makes: Whole crickets: 4.047 * 488,4 = 1.976.555 Kg per acre per year Protein only: 4.047 * 100,1 = 405.105 Kg per acre per year
This means that crickets utilize space 494,1 times more efficiently!
Of course, crickets use much more resources and are more expensive per Kg then soy. I just think that it gives perspective and especially hope to our situation :)
P.s. Does anyone know if the yields for soy are wet weight and if so, what is the wet weight protein content of soy beans? Makes it possible to compare protein yields to protein yields.
