Soil health best achieved by minimal soil disturbance, maximizing plant diversity, living roots yearlong, covered soil at all times with plants-residue
It seems in recent years it has become all the rage to make sure that the dirt under our feet – and plants or trees – is healthy in order to sustain farming.
Soil health was the chief topic at a University of California soil health field day held at Five Points, attended by about 200 people including boots-on-the-ground farmers and researchers.
Jeff Mitchell, University of California (UC) Cooperative Extension cropping systems specialist at Fresno County, has been toiling in the trenches – literally – for some 20 years, seeking to illustrate the value of cover crops, and no or low-till agriculture.
At the workshop held at the UC West Side Field Station, Mitchell had trenches to showcase, pits that showed differences between conventional and no-till farming. Speakers on hand discussed some of those differences.
Improved soil health
Mitchell, the growers, and others emphasized that managing for better soil health was best achieved by minimizing soil disturbance, maximizing the diversity of plants in rotation or used as cover crops, keeping living roots in the soil as much as possible, and keeping the soil covered with plants and plant residue at all times.
“I have something growing in the ground 365 days a year,” said Scott Park with Park Farming in Meridian in the Sacramento Valley. “Having roots in the ground is 10,000 times better than adding biomass.”
