Online-Based Continuing Education for Growers
The California Central Valley Regional Water Quality Control Board requires growers to prepare Irrigation and Nitrogen Management Plans (INMP) for land enrolled in the Irrigated Lands Regulatory Program. For land in areas designated as a high-vulnerability groundwater area, INMPs must be certified by a specialist or by a grower who has attended a California Department of Food and Agriculture (CDFA) …
Certifying Irrigation and Nitrogen Management Plans
The Central Valley Regional Water Quality Control Board requires growers to prepare Irrigation and Nitrogen Management Plans (INMP) for land enrolled in the Irrigated Lands Regulatory Program. INMPs are designed to promote awareness of irrigation and nitrogen management practices among growers and reduce the likelihood of nitrate, from fertilizer, entering the groundwater and degrading water quality. For land in an …
Nitrogen Management Training for Certified Crop Advisers
The University of California Agriculture and Natural Resources (UCANR), in partnership with the California Department of Food & Agriculture (CDFA) Fertilizer Research and Education Program (FREP) and the California Association of Pest Control Advisers (CAPCA) are offering the last in-person Nitrogen Management Training for Certified Crop Advisers (CCA). CCAs who complete this training are eligible to certify Irrigation and Nitrogen …

Recap: The 2019 FREP/WPHA Nutrient Management Conference
The 27th annual Fertilizer Research and Education Program (FREP) and Western Plant Health Association (WPHA) Conference took place in Fresno, California, on October 28-30, 2019. Speakers from industry, academia and agricultural consulting provided pioneering information on nutrient and irrigation management in California agriculture. Below you will find highlights of some of the talks at this year’s conference. The PowerPoint presentations …
Updated Fertigation Book
In California agriculture, there has been a gradual shift from gravity-fed irrigation to pressurized systems including micro-irrigation. Micro-irrigation systems have been implemented in over 60% of irrigated acreage in California and support a more intensively managed production system. The use of pressurized irrigation systems has made significant advancements possible, including more precise delivery of chemicals and nutrients to crops. Chemigation …
Role of Mineralization in Farming
California growers have taken on an important role in their state’s broader efforts on climate change, including responding to regulatory requirements to improve their nitrogen (N) use efficiency and reduce their environmental impact. To meet these regulations, while maintaining crop yield and quality, growers must consider all potential N sources, including organic amendments and irrigation water. It is essential that …
Approaching Research Data and Trials
The agriculture industry is continuously advancing and investing in new technologies and products, making it important to take a thoughtful and informed approach to planning and decision making. The following is a list of considerations to reference the next time you are looking at research results: 1. Data: If you are considering a new product or practice, do not be …
