Here is another way of natural weed control for a totally poison free agriculture. Still, and in my view, shearing and using weeds as a mulch is a far better alternative since this generates a fully biodynamic agriculture which becomes richer, and more fertile season by season and year by year (see
WEEDS in these pages).

Original Abstract:
AGRICULTURAL ECOLOGY: Weed Control
Weed suppression in cropping systems is generally achieved by herbicides, mulching, or mechanical means, all of which add substantially to the costs of farming. As an alternative, Weiner et al. examined the effects of manipulating crop density and spatial distribution on weeds. Using several varieties of wheat, they found that weed suppression was greatest at high crop densities, and when crop plants were evenly distributed (rather than planted in rows). Among the different varieties of wheat, there was a tradeoff between the ability of the plants to compete at high versus low density. Thus, the development of high-density varieties, together with more uniform sowing distributions, might reduce reliance on other means of weed control and take advantage of the natural competitive abilities of plants. -- AMS J.
