AUDIE CORNISH, HOST: The House has voted to repeal the Affordable Care Act. While the House has voted more than 50 times in the past four years to repeal the law, or parts of it, this was the first vote for a total repeal since 2013. NPR's Juana Summers joins us from the Capitol with the latest. Hey there, Juana.
1. Soil Type: Sandy. Sandy soil has the largest particles among the different soil types. Itâs dry and gritty to the touch, and because the particles have huge spaces between them, it canât hold on to water. Water drains rapidly, straight through to places where the roots, particularly those of seedlings, cannot reach.
Although clay can hold the most water of all soil textures, very fine micropores on clay surfaces hold water so tightly that plants have great difficulty extracting all of it. Thus, loams and silt loams are considered some of the most productive soil textures because they hold large quantities of water that is available for plants to use. 3. Organic matter. Organic matter is the next basic component that is found in soils at levels of approximately 1% to 5%.
