Growers of organic vegetables and strawberries across California are invited to attend an online training to learn how to manage nitrogen fertilization. The University of California Cooperative Extension (UCCE) is offering the three-part Nitrogen Planning and Management in Organic Production of Annual Crops Workshop on November 29, December 5, and December 12.

Growers, certified crop advisers, pest control advisers, and other agricultural professionals who are interested in learning about nitrogen management in organically farmed crops are encouraged to enroll.

The workshop is also available in Spanish.

Tuesday, November 29, 1–3 p.m.
Part 1: Understanding nitrogen: The nutrient, the role of microbes, and the relevance of soil organic matter.

Daniel Geisseler, UC Cooperative Extension specialist in nutrient management at UC Davis; Radomir Schmidt, program manager for the Working Lands Innovation Center at the UC Davis Institute of the Environment; and Margaret Lloyd, UCCE small farms advisor will give an overview of the sources, transformations, and fates of nitrogen in soil. They also will discuss the role and dynamics of microbes in nitrogen management and how nitrogen fixation impacts management decisions.

Monday, December 5, 1–3 p.m.
Part 2: Estimating nitrogen release from organic amendments and contributions from cover crops.

Patricia Lazicki, a postdoctoral research associate at the University of Tennessee, Knoxville, and Lloyd will discuss estimating nitrogen release from compost, organic fertilizers, cover crops and crop residue and irrigation water.  

Monday December 12, 1–3 p.m.
Part 3: Putting it all together: Completing a nitrogen budget, synchronizing nitrogen release with nitrogen demand, and using soil tests.

Joji Muramoto, UC Cooperative Extension organic production specialist; Richard Smith, UC Cooperative Extension vegetable crops advisor; and Lloyd will address nuances of organic soil fertility management in vegetables. Discussions will include crop nitrogen demand and strategies to supply demand, as well as using and interpreting soil testing. Specific references will be made to strategies for complying with forthcoming regulations. The session will conclude with a discussion on new frontiers in organic nitrogen management.

Registration for the virtual event is $25 and includes all three classes. A single registration can be shared by members of the same farm. Space is limited to 75 participants. To register, visit https://ucanr.edu/organiccrops22.

Participants may earn six hours of CDFA-INMTP  continuing education credits (formerly CURES CE Credits) or six hours of CCA  credits.
