The key factors that influence soil formation are climate, parent material, topography, organisms, and time. Climate, especially temperature and precipitation, determines the rate of weathering and types of organic material. Parent material provides the initial minerals and properties. Topography influences moisture and temperature. Organisms like plants and microbes break down materials and mix the soil. Finally, soil formation is a long process, and soils change and develop over hundreds of years as these factors interact.
Soil
Soil pH and permeability are important soil properties that affect plant growth. Soil pH indicates acidity or alkalinity levels and can be measured using a probe or colorimetric kit, with ideal levels varying by plant. Extremes in pH impact nutrient availability and symbiotic relationships, with common causes of low pH including nitrogen fertilizers and crop removal. Soil permeability refers to water and air flow and is assessed by texture, with clayey soils having very slow permeability and sandy soils being rapid. Permeability can be estimated visually or through field tests measuring flow rates.

Physical properties of soil
This document summarizes several key physical properties of soil: soil texture refers to the proportion of sand, silt, and clay and is estimated using feel or sedimentation methods; soil structure describes how primary particles are aggregated and affects properties like aeration; soil density measures bulk density and particle density which impact water and air movement; porosity refers to pore space between particles and influences moisture and gas exchange; consistence describes soil cohesion at different moisture levels; and soil color provides clues about drainage conditions and chemical processes from hue, value, and chroma measured using a Munsell chart.
Characteristics of soils
Soils are complex mixers forming the skin of the earth's surface. Soil is a dynamic layer in which many complex chemical, physical and biological activities are going on constantly. Soils become adjusted to conditions of climate, landform and vegetation, and will change internally when those controlling conditions change. Soils are products of weathering. Soils play a dominant role in earth's geomorphic processes in a cyclic manner. The characteristics of soils are very essential for several reasons. This module highlights these characteristics.
Soil
Soils and growing media provide nutrients, air, water and support for plant growth. Key properties include physical attributes like texture, chemical properties that influence nutrient supply, and biological factors from microorganisms. Texture, structure, permeability and pH all impact aeration, drainage and plant suitability. Safety precautions must be followed when working with soils. Improvements can address texture, structure, pH, salinity through amendments, drainage or plant selection.

- 1. Soil Color Soil Physics PhD-I Presented By: Muhammad Usman Course Instructor: Dr. Jalil ur Rehman
- 2. Objectives • Definition of Soil Color • Causes of Soil Color • Classification of Soil Color
- 3. • Soil color is a property that can be used to describe horizonation and soil morphology. • The change in soil color with depth is directly related to a variety of processes that are occurring in the soil. • The soil color doesn’t affect the properties of the soil, but provides insight environmental conditions, formation processes and other influences on the soil. • Used in classifying soil. Soil Color
- 4. • Soil color doesn’t affect the behavior and use of soil, however, it can indicate the composition of the soil and give clues to the conditions that the soil is subjected to. • Soil can exhibit a wide range of colors like gray, black, white, red, brown, yellow and green under different conditions. Soil Color
- 5. Soil color is due to three main pigments: • Black: From organic matter • Red: From iron and Aluminum oxides. • White: From silicates and salts. Color can be a useful indicator of some of the general properties of a soil, as well as some of the chemical processes that are occurring beneath the surface. Classification of Soil Color
- 6. Soil color is influenced by the amount of proteins present in the soil. • Yellow or red color indicates the presence of iron-oxides. • Dark brown or black color in soil represents that the soil has high organic matter content. • Wet soil appears darker than dry soil. • The presence of water also affects the soil color by affecting the oxidation rate. Soil that has a high water will have less air in the soil, specifically less oxygen. • In well drained (oxygen-rich) soil red and brown color caused by oxidation are more common, as opposed to wet (low oxygen) soils where soil usually appears grey. Causes of Soil Color
