• Loam is a textural class wherein sand, silt and clay are in almost equal proportion in a soil mass.
• Sand has particles that range from 0.2 to 2 mm in diameter
• Clay - the finest of the soil separates which, as a result have very large surface area giving them tremendous capacity to hold water and nutrients
• Sand is gritty - Soil texture refers to the coarseness pr fineness of a soil
• Stoke - the physicist who formulated the law governing the rate of settling of particles in a viscous medium
• 5 - In the color munsell notation 10R 2/5, the chroma is
• Rice - A structureless soil as a result pf pudding is detrimental to the growth pf most upland crops but is beneficial to
• Soil Tilth - The physical state of the soil as it relates to plant growth known as soil
• Porespace - A portion of the soil volume occupied by air and water
• Soil Depth - The bulk density of a soil increases
• Percolation - The downward movement of water through the soil located between the root zone and the capillary fringe of the permanent groundwater table
• Electrical Resistance Block - An instrument made of porous gypsum suitably embedded with electrodes when placed in moist soil, the fine pores of the instrument absorb water in proportion to the soil water resistance
• Infiltration Rate - The amount of water that enters the soil per unit time per unit surface area
• Hydraulic Conductivity - The rate at which water moves through a given area under specified conditions
• Water Holding Capacity (WHC) - The ability of a soil to retain moisture against gravitational pull
• Saturated Water Content - The weight of water held by a soil when all pore spaces are filled with water
• Field Capacity - The maximum amount of water retained by a soil at any given pressure head
• Capillarity - The upward movement of water from the lower part of the soil profile to the upper part against gravity
• Saturated Hydraulic Conductivity (Ksat) - The maximum hydraulic conductivity of a soil
• Field Capacity - The maximum amount of water retained by a soil after excess water has drained away from it
• Permanent Wilting Point - The point where plants can no longer extract enough water from the soil to meet their needs
• Saturated Water Content - The amount of water held by a soil when all pore spaces are filled with water
• Permanent Wilting Point - The minimum point on the soil-moisture curve where plants can no longer extract enough water to meet their needs
• Soil Moisture Deficit - The difference between field capacity and permanent wilting point
• Permanent Wilting Point - The minimum point on the soil-water curve where plants can no longer extract enough water from the soil to meet their needs
• Porosity - The ratio of void space to total volume of soil
• Soil Moisture Tension - A measure of the force exerted by plant roots as they draw water out of the soil
• Soil Texture - A measure of the relative proportions of sand, silt, and clay particles in a soil
• Volumetric Water Content - The ratio of the volume of water present in a soil sample to the total volume of the sample
• Particle Size Distribution - The proportion of different size fractions present in a sample of soil
• Unsaturated Hydraulic Conductivity (Kunsat) - The hydraulic conductivity of a soil below field capacity but above permanent wilting point
• Permanent Wilting Point - The lowest level of soil moisture content where plants can no longer extract enough water to meet their needs
• Field Capacity - Occurs when the porspaces are filled with water or at its maximum water holding capacity
