Indeed, as crops become popular, there may be a desire to see increased acreage or cultivation of these, but in Canada, where we have some 68 million hectares of land, we have a very large base for crop rotation. All crop systems in eastern and western Canada are rotated. Soybean alternates with corn, canola alternates with wheat and barley and oats and flax. We also grow many pulse crops, nitrogen-fixing crops: soybeans, lentils, peas, chick peas, and various types of beans.
So there is a very active rotation, and I think it's important that our research emphasis on our key crops keeps developing, using genomic sciences and genetic sciences to develop the best and most competitive varieties so that the producers have a very good choice of which crops they want to use.
So we do not have a monoculture now; we have a good mix.
For example, canola is not grown on the same land consistently; only once every third year is it grown. Even with biofuel demand, the potential canola acreage is such that we can supply oil for edible use as well as for biofuel. The biofuels needs, according to the government's mandate for 2% biodiesel by the year 2012, would require about 15% of the canola acreage. Because we have such a large land resource, we have the capability of meeting these different markets.
