From Wheat to Citrus
From Wheat to Citrus is a skill on Pengi from Lesson 1: Agricultural Innovations in Pengi Social Studies (Grade 4).
Key Concepts
In the early days, California farmers grew mostly wheat because it was easy to ship without spoiling. But wheat prices fell, and farmers needed a change. They discovered that California's sunny climate and rich soil were perfect for high value specialty crops like oranges, lemons, and grapes.
This shift created a "Green Gold" rush. But unlike wheat, these delicate fruits needed many hands to pick them. Immigrant workers from China, Japan, and Mexico provided the essential labor that made this new agricultural economy possible.
