The primary objectives in using EENFs is to extend the availability of nitrogen in the rootzone and to control nitrogen loss.

Optimizing irrigation and nitrogen fertilization of coastal berry and vegetable crops Andre Biscaro, UCCE Ventura County Irrigation Advisor

Andre’s presentation will review nitrogen uptake and other plant developmental data of several berry and vegetable crops, with the purpose of addressing improved water and nitrogen fertilizer management practices. Additionally, tools for optimizing yield and minimizing nitrate movement, such as soil moisture sensors, soil nitrate quick tests and CropManage will be discussed.

Fertilization practices and nitrogen management plans in nursery productionLoren Oki, UCCE Specialist Environmental Horticulture

Loren’s presentation will address the issues and research that are being conducted on nitrogen management plans for nursery production. Currently, plans are a challenge for nursery producers because the entire plant and the soil are purchased and shipped together. Loren’s research hopes to address some concerns associated with nitrogen management plans in nursery production.

Diagnostic tools for nitrogen management of desert vegetables Charles Sanchez, University of Arizona, Department of Soil, Water and Environmental Science

Charles’s presentation will cover vegetable production in the desert and will address concerns about nitrate leaching below the root zone. He will also discuss decades of research on evaluating the use of tissue tests and soil tests as diagnostic tools for implementing efficient nitrogen practices.
