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.
Soil particles can be classified by their chemical composition (mineralogy) as well as their size. The particle size distribution of a soil, its texture, determines many of the properties of that soil, but the mineralogy of those particles can strongly modify those properties.he mineral material from which a soil forms is called parent material. Rock, whether its origin is igneous, sedimentary, or metamorphic, is the source of all soil mineral materials and the origin of all plant nutrients with the exceptions of nitrogen, hydrogen and carbon.
