The Ventura County Agricultural Commissioner’s Office will be hosting a series of continuing education opportunities in Laws & Regulations.
These sessions are open to anyone interested in renewing their PAC, QAL, QAC or PCA.
The first in these series will be held January 13, 2010 8am to 12pm at the PWA Conference Room located at 11251-A Riverbank Drive in Saticoy.
Topics covered:
- 2010 Permit Conditions
- Hazard Communication Regulation Changes
- Online Pesticide Use Reporting
- Pesticide Application Inspections
These sessions are free of charge and will provide up to 3 hours of DPR (Department of Pesticide Regulation) approved continuing education credits. If you are interested in attending this session, please contact Korinne Bell at 805.933.2926 ext 235. Space is limited so please call to reserve your spot!

Whether you are in the agricultural business, have a fondness for analyzing economic data, or simply curious about agricultural and resource economics, the University of California has a site for you.
Once there you can find the most recent cost and return studies, sorted by commodity, region or county. They are interesting to look at, and certainly provide non-growers a glimpse into the amount of variables and costs associated with crop production.
There is also a link to archived studies. There you can find studies going back to 1931.
In addition to commodity studies, the site has a tree and vine loss calculator link. This link will help operators determine the value of single trees or vines lost to any cause. The calculator covers major tree and vine crops produced in California, and has a variety of input categories to cover loss from any cause.
Cost studies for California Central Coast conservation practices are also available through this site. Each of the nine studies provides an estimate of expected benefits and details on typical installation, operation, and maintenance expenses.
The site can be found by clicking here.

Did you know that California employers are required to take four steps to prevent heat illness? The steps are:
- Training employees and supervisors about heat illness prevention.
- Provide enough fresh water for each employee to drink at least 1 quart per hour, and encourage them to do so.
- Provide access to shade for at least 5 minutes of rest for an employee who believes they need a preventative recovery period.
- Develop and implement written procedures for complying with the Cal/OSHA Heat Illness Prevention Standard.
Further information can be found at the California Department of Industrial Relations Division of Occupational Safety and Health (DOSH) at http://www.dir.ca.gov/dosh/HeatIllnessInfo.html. Main topics for further heat related information are:
- Heat illness training – including seminars and PowerPoint training in English and Spanish.
- Heat illness regulation.
- Heat illness prevention publications – many available in English and Spanish.
- Additional heat illness links.
The University of California has heat stress information as well as many other safety tips at http://groups.ucanr.org/ehs/Safety_Notes/.

To protect water resources and comply with increasing regulation, greenhouse managers are wise to make changes to prevent pollutants, such as fertilizers, pesticides, and container media from ending up in surface and ground waters. One way to do this is to use vegetated buffers.
Vegetated buffers are areas or strips of land maintained in permanent vegetation to prevent erosion and improve water quality by trapping and treating contaminants. Vegetative buffers can also provide many other benefits such as increasing beneficial insects for biological control of crop pests and protecting streambanks. In addition, they can be used for green waste and secondary crop production.
Some examples include vegetated buffers are bioswales, vegetated filter strips, and constructed wetlands.
- A vegetated bioswale is a stormwater conveyance system that channels stormwater. This type of buffer system improves water quality by reducing flow velocity and increasing sedimentation, filtering pollutants, and allowing infiltration into the underlying soils.
- A filter strip is a band of vegetation that can be used between a greenhouse and a waterbody. The purpose of the filter strip is to slow runoff from the production area and trap sediment, fertilizers, and pesticides before they reach surface water.
- A constructed wetland is an artificial marsh or swamp for treating wastewater, controlling flood waters, and reducing erosion. In greenhouse production, they can be built to further remove pollutants in the effluent from a retention basin.
Although there are different types of vegetative buffer systems, most work in a similar manner. Runoff containing soluble nutrients and pesticides, and sediments with adsorbed pesticides, enters the buffer. Vegetation in the buffer slow surface flow and sediments drop out. Some water infiltrates into the root zone and subsoil, while the remainder becomes lateral subsurface flow. When the roots of buffer plants grow to sufficient depth, they intercept infiltrated water, taking up the soluble nutrients and pesticides. Pesticides adsorbed to soil particles become trapped in the root zone, and high soil organic matter provides conditions for denitrification and pesticide degradation.
Things to consider before constructing a vegetative buffer.
When planning and designing a vegetative buffer, it is best to consult a licensed engineer or the Natural Resources Conservation Service (NRCS). Buffers need to be designed and constructed to comply with all federal, state, and local laws and regulations.
Plant species that are used in buffers should be selected based on their adaptability and tolerance to site conditions. Check local information sources, such as the NRCS and Cooperative Extension, before making selections. Some points to consider are: cost, growth rate, potential of plant invasiveness if not using native plant species, and the ability to use the buffers for producing secondary crops. Growers who are interested in developing techniques to produce secondary crops in vegetative treatment systems should contact Cooperative Extension and the NRCS for guidance.
Planting should be timed so buffers are established prior to expected runoff. Maintenance of vegetative buffers is necessary to sustain buffer function and effectiveness.
