Sampling for coarse roots. What is the role of larger tree roots? Water delivery? Structure and support? In this video we use the powerful Air Spade to blow away sand and soil and learn more about tree roots of the Kalahari.
Soil coring for fine roots. Examining fine roots helps us understand the strategies that vegetation uses to survive with so little water. Coring sandy soil is a relatively fast and easy way to sample fine roots.
Extracting fine roots. We are learning that during the rainy season trees of the Kalahari enlarge their fine root systems so that they can intercept valuable water and nutrients. This video shows the everyday tools you need to examine fine roots.
