Those techniques successfully averted mass starvation a generation ago. But now, green revolution practices are threatening the food supply for future generations. One of the promises of genetically modified food is that it helps minimize the need for pesticides and fertilizers, and may help reduce the threat to future food supplies. But opponents of GM food say that solution poses more problems than it solves. Colorful flowers sprout up between the vegetables.
Clover covers the ground.
So what we do here, we're doing experiments where we're mixing the cauliflowers, for example, with fava beans. And fava bean is an important plant because the fava bean is legume that fixes nitrogen. So therefore by fixing nitrogen they can connect with the roots of the broccoli and therefore do a transfer of nitrogen into the plant and you don't have to use a chemical fertilizer. The premise is that every challenge in agriculture can be met with a natural, organic solution, instead of fertilizer, pesticides, or the new kid on the block, genetic modification. Plant it next to fava beans, which trap nitrogen.
