Remember physical properties are the things we can observe about a substance using our five senses.. For soil, the two main physical properties are color and texture.. Texture. Introduction to Agriculture. Soil Science. Unit 2. Physical Properties. Physical properties or characteristics of the soil determine to a large degree how useable and productive soil will be. Productivity of soil is affected by the physical properties of soil. Objectives. Define: ammonification, ammonium, bulk density, . denitrification. , immobilization, leaching, mineralization, nitrate-N, nitrification, soil nitrogen fixation, volatilization. List and describe inherent factors that affect soil nitrogen. Uppermost layer of earth’s crust that supports plants, animals and microbes. Soil Forming Factors. Parent Material. Time. Climate. Vegetation & Organisms. Topography. 1. Parent Material. Refers to the rock and minerals from which the soil derives.. Skye Wills. NCSS, 2011. Soil and Ecosystem Change. Soil Change Guide. Document change in soil function applicable over the entire extent of a soil series or component phase. When possible, Ecological Sites and associated State and Transition Models inform study design and interpretation.
