Day 2: Data Collection Day Three-lesson education module developed by the Asombro Institute for Science Education
Remember Soil Texture Soil Texture helps determine: How fast water moves into and through the soil How much water is available in the soil for plants to use Clay stores the most water in total, but can hold onto the some of the water too tightly for plants to use Silt stores the most plant-available water. Sand stores the least amount of water for plants.
Soil Texture at Multiple Depths Plant roots can penetrate deep in the soil (Figure A). Soil texture often changes as you move farther underground (Figure B). Because of this, it is important to know what the soil texture at different depths where plant roots might occur. Figure A Figure B
Land Cover Why Its Important Describing the types of land cover and vegetation can give us an idea of how our landscapes resist and recover from disturbances (i.e. erosion). % of Land Cover % of Land Cover Erosion Risk Erosion Risk Knowing what land cover and vegetation are at a site can also give us a baseline to set goals or track future changes.
Day 3 Land Management Planning Input data into the LandPKS app for analysis Learn about LCC (Land Capability Classification) Identify LCC from your site Apply LCC understanding to a potential land management dilemma
