Celebrate one of the world's most amazing precious natural resources, SOIL! You're invited to a day of learning, discovering, creating, connecting, and experiencing the key role soils play in our daily lives through a collaboration between Wild Willow Farm & Education Center, and the Resource Conservation District of Greater San Diego County.

Explore two unique soil-supporting operations -- a community garden and an educational farm -- located in the Tijuana Estuary just 15 minutes south of downtown San Diego.

Family-friendly activities will be offered at both locations, and workshops for all levels of soil enthusiasts will be held in the morning and afternoon at Wild Willow Farm and The Tijuana River Valley (TRV) Community Garden.

TRAVEL The best way to get to the Tijuana River Park area where this event is located, is to take the Tocayo exit from Southbound I-5, just north of the Mexican border (Exit 3). Click here for a map.

Maria Gallaher, Teacher, Chula Vista High School

It is common to see small gardens on campuses, but when was the last time you saw an organic student farm run and operated by students? This is exactly what is happening Chula Vista High School. The goal is to create a farm to cafeteria program that will sustain a healthy salad bar for students to enjoy all year round.
Students learn about soil science, how to install water-saving drip irrigation systems, how to live more sustainably by composting waste and recycling, and how to improve their health by eating the food they grow. This last point is of great significance as students from the west side of Chula Vista suffer from higher rates of obesity that can negatively impact their learning and their life expectancy.
