A group of California organic farmers is sharing information about their efforts to combine reduced tillage with the use of cover crops, which they have been planting on their vegetable farms for decades to protect soil while adding carbon and diversity to their production systems.
“Every one of the pioneering farmers has seen tremendous benefits from the practices,” said Jeff Mitchell, UC Cooperative Extension vegetable crops specialist. “These are the very growing practices that we have demonstrated over two decades of research to benefit soil health, environmental conservation and the bottom line on plots near Five Points in Fresno County.”

Growing caneberries under tunnels keep the berries dry even when it rains, preventing disease and assuring fruit quality. However, during rains, water drains from the plastic down into rows that contain the anchoring posts of the tunnel structure. The accelerated runoff in these post rows causes soil erosion and sediment and nutrient loss. Persistent soil moisture in post rows also promotes weed growth. While weeds growing in the anchoring rows do not directly compete with canes, they can reproduce and quickly spread into neighboring cane rows.
Rather than using herbicides in caneberry growing tunnels, the UC Integrated Pest Management program suggests planting a cover crop to prevent weeds in anchor rows.
