Abstract
The purpose of this study was to investigate the sustainability of
alternative cropping systems in the Brown and Dark Brown soil zones of
Saskatchewan. Three components of sustainability are examined;
economic effects, environmental effects and social acceptance.
The primary objective of this project is to investigate the short and
long-term economic effects of introducing pulses and oilseeds into
existing cereal crop rotations. Representative farms were developed and
used in the assessment of profitability and risk for four competing
alternative rotations including a cereal based benchmark system.
Production costs, financial linkages and stochastic prices and
yields are used to simulate farm income, expenses, cash flows and net
worth for a 15 year period. Stochastic dominance testing is used to
determine the profitability and risk for each of the competing rotations
based on annualized net returns.
The second objective was to identify the change in soil productivity
and resource use efficiency from the widespread use of these new cropping
systems. The EPIC model is used to simulate a 30 year cropping pattern
for each of the alternative crop rotations. The simulation results indicate
that there are rotational benefits in short-term off-site resource usage.
The results of the whole farm production model support the
following conclusions. (1) Rotations that include lentil, with low price and
yield correlations, produce higher net farm income and lower have
economic risk. (2) Market risk is reduced by increasing cropping diversity.
(3) Production risk is highest in the early adoption phase. (4) There is a
cost savings in nitrogen fertilizer usage for crop rotations that include
lentil; however, this cost savings is diminished by increased chemical and
equipment costs. (5) Extended rotations that include lentil and canola are
preferred over 2-year and 3-year wheat-fallow rotations by risk averse
producers in the Brown and Dark Brown soil zones.
