Cal Poly Center for Sustainability to Hold March 12 ‘Nutrient Logic’ Seminar for Growers

SAN LUIS OBISPO — Cal Poly’s Center for Sustainability will host a lunchtime seminar by Steve Trotter titled “Nutrient Logic for Soil Health: Managing Nutritional Programs in Declining Soil and Water Conditions,” from 11:30 to 1 p.m. Tuesday, March 12, in San Luis Obispo.

Soil plays a critical role in plant health and immunity. One of the best tools for promoting soil health is an understanding of soil nutrition. Trotter’s presentation will examine basic factors involved in appropriate nutrient management to improve soil function. Topics will include supporting soil biomass function, identifying limiting factors such as soil physical properties’ critical nutrient relationships, and biostimulant and catalyst tools.

Trotter is an independent researcher for agriculture and turf and consultant for Agroplasma. His presentation will be followed by a group discussion with ample time for audience questions.

The seminar will be held at the University of California Cooperative Extension (UCCE) Auditorium, 2156 Sierra Way, San Luis Obispo. It is co-hosted by Surendra Dara, UC Cooperative Extension advisor for entomology and biologicals, and co-sponsored by the Department of Agriculture Natural Resources Conservation Service and the Coastal San Luis Resource Conservation District.

This free, brown-bag event is open to everyone, but registration is requested. Attendees are asked to bring their lunch, soil questions, and a friend. Register at
