organic systems had higher organic
matter inputs. In the systems included
in this meta-analysis, the organic
matter inputs in the form of manure
or compost were on average 65%
higher on organic farms compared to
conventional farms, when calculated
as an average of the relative inputs by
weight (organic/conventional) in each
case.”

this review, the authors expanded
previous estimates using novel
primary data from 200 countries and
found that fruit, vegetable or seed
production from 87 of the leading
global food crops is dependent upon
animal pollination, while 28 crops do
not rely upon animal pollination.
