Organic dairy farming systems were compared with conventional (defined here
as the prevailing high-technology, high-intensity) dairy fanning systems i
n the province of Ontario, Canada from both technical and economic standpoi
nts, over a three-year period. Primary data were collected from organic far
mers as part of the study, patterned on a data collection protocol for conv
entional dairy farmers extant since 1976. Comparability between the samples
drawn from the two subpopulations with respect to farm size, climate, natu
ral resource endowments, and emphasis on dairying ensured to the extent pos
sible that differences in performance reflected differences in farming syst
ems and management procedures.
The study findings revealed a superior technical performance on conventiona
l farms, as measured by milk yield per cow and milk shipments per ha of lan
d and per person equivalent. In contrast, economic performance was found to
be superior on organic farms, by virtue of the much lower costs of product
ion for almost all material inputs, including dairy herd replacements and l
ivestock feeds. The lower costs were rooted in an apparent bid by organic d
airy farmers to be as self-sufficient as possible in plant nutrients, anima
l nutrients and replacement livestock. The majority of land on organic farm
s was devoted to feed crop production to support the dairy herd. Convention
al dairy farmers tended to import large portions of their inputs across a b
road range from crop seeds through synthetic chemical fertilizers and pesti
cides to feedstuffs and herd replacements. Much land on conventional farms
was allocated to cash crop production. Consequently their costs of producti
on and marketing were higher, more than offsetting the higher revenues gene
rated.
