#AP Human Geography: Agriculture Study Guide 🌾

Hey there! Let's get you prepped for the AP Human Geography exam. This guide is designed to be your go-to resource for all things agriculture, focusing on what you really need to know for test day. Let's make this exam a breeze! 💪

#How Agriculture Has Changed Over Time

Agriculture has dramatically evolved, especially with tech advancements and cultural diffusion. Here's a quick rundown:

Mechanization: Increased use of machines like tractors and harvesters has boosted efficiency. 🚜
Irrigation: Better water control leads to consistent crop yields. 💧
Fertilizers & Pesticides: Improved pest and disease control, resulting in higher yields. 🌱
Genetic Modification: Crops with desired traits (pest resistance, etc.). 🧬
Sustainability: Focus on eco-friendly farming to conserve resources. 🌍

Key Concept

Understanding these changes is crucial, as they often appear in both multiple-choice and free-response questions. Pay attention to how each change impacts productivity and the environment.

#Early Hearths of Agriculture
