Then for a true picture the total yield in some unit, dollar or pounds

really behind modern methods. With total production nearer 25% or less that
of a modern farm ran in an intensive operation.

Bear in mind;
'2. Lower yields are experienced during the transition to organic production
Most researchers agree that yields tend to drop for three to five
years during the conversion from industrial to organic approaches (Dabbert
and Madden, 1986; US Congress, 1983; Hanson et al, 1990; Lampkin,
1989; Smolik and Dobbs, 1991). This is because it takes time for the soil
to develop the positive attributes associated with organic agriculture. It
also takes time for operators to learn organic crop management techniques.
Some of the lower organic crop yield estimates cited in Exhibit III-1
may have been from industrial farms in transition to organic production.

Given that organic production relies on soil fertility and a healthy,
diverse soil ecosystem, the yield reductions experienced in the initial
phases of transition from industrial practices tend to be eliminated over
time (Sparling et al, 1992; pers. comm. Cornwoman; pers. comm. Tourte).
We note that the economic transition time can be twice as long as the
biological transition time; it can take an extra four years for the
farmer to fully recoup the financial losses that occurred during the
transition (Hanson et al, 1990). This transition period can be shortened
significantly with creativity (e.g. substituting crops, enhancing farm
gate sales efforts).

3. Organic crop yields are less variable than industrial yields

Organic crop yields are reportedly less variable than industrial
methods (Hanson et al, 1990). As well, growing season precipitation is
an important factor influencing crop yields and organic crop production
systems appear to perform better than industrial farming systems under
drought conditions (Smolik and Dobbs, 1991). Thus, sustainable crop
production provides a benefit to risk-averse farmers.

Based on the above, it appears that with strong farm management, small
scale, organic crop production can produce competitive and even superior
yields to industrially grown crops. Furthermore, just as research has
resulted in an improvement in yields for industrial crops (e.g. winter
wheat), there is likely to be similar improvement in yields for organic
crops as more research is conducted and organic farming methods
become more commonplace (Lampkin, 1989).
