This network is a comprehensive information and communications resource for berry and grape production practices, research, and marketing sponsored by Oregon State University, Washington State University, the University of Idaho, and the USDA Agricultural Research Service. Strawberries information.

 UC Farm Water Quality Planning Program

The Farm Water Quality Planning program is a coordinated effort by the UC Division of Agriculture and Natural Resources cooperating with the Natural Resource Conservation Service. The goal is to improve water quality education to the irrigated agriculture industry in California.  A number of resources can be accessed from this website including all of the Farm Water Quality Fact Sheets. County specific water quality resources and contacts are available although some of the contact information has not been updated since the educational programs were completed in 2007. 

 UC Fruit and Nut Research and Information Center

The Center provides best management practices developed by UC Cooperative Extension and direct connections to cutting edge research, new technologies and innovations, as well as practical advice in fruit and nut production. Strawberry information.


The UC IPM website contains information about managing agricultural pests, including UC's official guidelines for monitoring pests and using pesticides and non-pesticide alternatives for managing insect, mite, nematode, weed, and disease pests. Pest Management Guidelines for Strawberry. Pesticide properties and water quality risk information are also available.

UC Davis Agricultural & Resource Economics Coastal Conservation Practice Studies

The UC Davis Department of Agricultural and Resource Economics has “Studies for Central Coast Conservation Practices” available in pdf format. Each study describes a particular practice and provides a partial budget table estimating costs (costs per unit and reduced returns) and potential benefits (additional returns and reduced costs) for its installation, operation and maintenance. Costs and benefits are shown for low, representative and high cost scenarios. More detailed information on labor and material inputs for the representative scenario is contained on two additional tables. Cost studies include an annual cover crop, grass filter strip, grassed waterway, water/sediment control basin, on-farm row arrangement (including strawberry) and hedgerow planting, among others.

UC Riverside PesticideWise

This website can be used to search through a comprehensive EPA-USDA database and find critical information on a pesticide's properties and water quality risks.

UC Sustainable Agriculture Research and Education Program

The UC Sustainable Agriculture Research and Education Program (SAREP) provides leadership and support for scientific research and education in agricultural and food systems that are economically viable, conserve natural resources and biodiversity, and enhance the quality of life in the state's communities. SAREP serves farmers, farmworkers, ranchers, researchers, educators, regulators, policy makers, industry professionals, consumers, and community organizations across the state. Program areas include biologically integrated farming systems, methyl bromide alternatives, organic farming information, and crop production, among others. There is also a database on cover crops.

UC Small Farm Program

The UC Small Farm Program focuses on the challenges and opportunities of California's small-scale farm operators. Field and marketing research aimed at the needs of small- and moderate-scale farmers is developed and provided to farmers who are often not reached by traditional extension programs. Clients include farmers of many different cultures who operate a wide variety of farming operations, often with limited resources.

UC Water Resources Center

The mission of the UC Water Resources Center is to stimulate and support water and water-related research. One program, The UC Cooperative Extension Water Quality Program, seeks to reduce the need for restrictive regulation and, in a manner that maintains agricultural productivity, avoid economic hardship and sustain an economical, safe supply of food and fiber.

UC Weed Research and Information Center

The Weed Research and Information Center is an interdisciplinary collaboration that fosters research in weed management and facilitates distribution of associated knowledge for the benefit of agriculture and for the preservation of natural resources.



UC Cooperative Extension (UCCE) is the public service division of the University of California, focusing on issues relating to agriculture, natural resources and communities. UCCE is a collaboration between UC and the County. This county-based service is your direct connection to University knowledge and expertise.

Resource Conservation Districts (RCDs) are special districts organized under the California Public Resources Code. They have no regulatory function, but are charged with carrying out natural resource conservation programs within their boundaries. RCDs can provide public education, hire employees, provide technical assistance, enter into cooperative agreements, charge for services, own and or operate land, apply for grants and provide guidance to partnering agencies and organizations on conservation issues. The USDA Natural Resources Conservation Service (NRCS) has entered into mutual agreements with RCDs nationwide to provide technical assistance, free of charge, to landowners and others with conservation needs. RCDs working in cooperation with NRCS have been providing assistance to land users, schools, groups, organizations and the general public for more 60 years.

Ventura County

Ventura County Resource Conservation District (VCRCD) has a lead role in the implementation of the measures recommended for agriculture water conservation including on-farm evaluations, such as mobile irrigation lab irrigation evaluations, and workshops, field tours and expanded educational services. VCRCD also has a vital role in helping Ventura County growers comply with conditional waiver requirements by facilitating best management practices (BMPs) implementation and conducting surveys to help growers identify mitigation practices and develop water quality plans. Technical expertise and field experience of NRCS conservation specialists can be accessed to assist landowners in solving their natural and agricultural resource challenges. VCRCD assists in the preparation and review of Hillside Erosion Control Plans on new agricultural developments in critical areas (sloping lands) and co-manages the Calleguas Creek Permit Coordination Program that will significantly simplify the permitting process for those wanting to undertake certain conservation practices.

The Natural Resources Conservation Service (NRCS), a federal agency of the USDA, is responsible for providing natural resource conservation assistance to private landowners. NRCS staff  have expertise in soils, engineering, wildlife biology, range and cropland management to provide comprehensive resource management planning to landowners. Various publications, including management practice technical guides, and services are available on the website. The NRCS provides free technical planning assistance to farmers, ranchers, and rural land owners to address resource concerns. Some NRCS offices may also have specialists that work exclusively on water quality issues as part of the AWQA. The NRCS provides assistance to landowners through several voluntary USDA cost sharing and incentives programs such as the Environmental Quality Incentives Program (EQIP), which offers financial and technical assistance to eligible participants for the installation of vegetated, structural and management practices such as soil erosion, water quality and quantity improvements, and wildlife habitat restoration. Limited resource producers and beginning farmers and ranchers may be eligible for cost-share up to 90 percent. See http://www.nrcs.usda.gov/programs/eqip/ for an online EQIP application. A list of NRCS offices and associated District Conservationists are listed below. The District Conservationist in each office can arrange for a site assessment and consultation with hydrologists, engineers, and other NRCS staff.
