In this agribusiness lesson, we covered the analysis of soil and water using a zigzag pattern for collecting soil samples, which is essential for conducting tests like conductivity and pH levels. The session emphasized revisiting previous lessons for detailed understanding and introduced a practical component with a video from California Gardening, demonstrating how to use the Soil Master soil testing kit. This kit, available on Amazon, provides the necessary tools and chemicals to ensure your soil has adequate nutrients, vital for optimal plant growth.
