This month we have been thinking about how conservation agriculture can work with horticultural crops. Please, read on!
CONSERVATION AGRICULTURE: NOW FOR VEGETABLES TOO? Mostly used with field crops, conservation agriculture combines three practices to improve soil health: minimal soil disturbance (“no till”), continuous mulch cover, and planting diverse crops. Manuel Reyes of North Carolina A&T State University has been working with our program to find out how vegetable farmers can benefit from using conservation agriculture practices. See highlights below or read the whole article: http://bit.ly/1ybrCXs
With Ph.D. student Don Immanuel Edralin and USDA funding, Reyes began focusing his conservation agriculture work on vegetables with small, intensive plots in North Carolina. Next he led a USAID-funded project with support from the Horticulture Innovation Lab and the SANREM Innovation Lab to compare combinations of conservation agriculture and drip irrigation for vegetable farmers in Cambodia.
In agronomic systems, yields sometimes decrease temporarily during the first transitional seasons of using conservation agriculture. In his work with vegetables in Cambodia so far, there have been no significant differences in yields between treatments.
What has changed with the new practices was the vegetable farmers’ labor. The researchers estimate that growing vegetables on 100 square meters with traditional methods and hand watering requires hauling about 1,300 pounds of water per day during the dry season. Drip irrigation and conservation agriculture freed the women farmers from carrying water, tilling and weeding.
In fact, many of the women farmers were so pleased with the new practices that they asked to end the experiment early, to avoid the extra labor of tilling, hand-watering and weeding required to maintain the field tests. Reyes will continue to work with these farmers, with a new Horticulture Innovation Lab project focused on further spreading the use of conservation agriculture among vegetable growers and marketing vegetables grown with these soil-conserving practices.

14 STEPS TO GROWING VEGETABLES WITH CONSERVATION AGRICULTURE AND DRIP IRRIGATION
As told by Manuel Reyes, professor, North Carolina Agricultural & Technical State University:
1. Manually till and weed a small plot of land (no more than 200 square meters).
2. Make vegetable beds.
3. Find a source of mulch for your site. Mulch should not contain seeds and not grow vegetatively.
4. Cut mulch and let it dry.
5. Install drip irrigation on the site.
6. Put dried mulch on the entire area including the furrows between the vegetable beds. Mulch should be at least 2.5 inches thick.
