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. The delicacy of clay crystals. Soil crumb structure. Do not abuse clay!. Add plenty of organic matter. Avoid over-cultivation especially rotary cultivation. Use lime of gypsum to improve structure.
