PLNT 1213 Lecture Notes - Lecture 10: Soil Organic Matter, Soil Texture, Tilth
Document Summary
What is soil: _______________________________________________________________, with loose material at or near earth"s surface properties that can sustain life due to it"s proximity to the surface. Soil development: soil develops as a result of the combined effect of _____________ and _____________ organisms climate acting on _________________________, as influenced by _________________ over parent material topagraphy. Soil horizon: a layer of soil parallel to the surface differing in characteristics from the soil above and below. How does soil affect plants: soil provides plants with, ______________________ a place to anchor roots, ______________________ water, ______________________ mineral nutrients. Soil tilth: ________________________________________________________________________ physical conditions of soil as it relates too tillage, planting, germination and emergence. _____: a soil with good tilth will have adequate pore space to hold water and air, will have an adequate supply of nutrients. Soil tilth: this is a function of. ____________________________________________________________________: maintaining soil tilth requires careful timing of farming operations and is improved by reducing tillage.
