Water-holding capacity is defined as the water retained between field capacity and wilting point. Field capacity is the saturated state of water in the soil that can drain freely due to the force of gravity. Wilting point is the soil water level after its absorption by ...
Gardeners can test acidic or alkaline levels of soil with a pH testing kit, or use a do-it-yourself method with vinegar and baking soda, according to Organic Gardening at About.com. Scoop soil into a plastic container, and pour 1/2 cup of vinegar into the container. If ...
Water holds heat longer than soil because water has a higher heat capacity than soil. Water's high heat capacity results from the large amount of heat energy required to break the hydrogen bonds in individual water molecules.
Soil testing involves collecting and analyzing a soil sample to determine the quantity of nutrients and elements such as potassium, phosphorus, calcium, copper and zinc. Soil testing also measures the humic matter, exchangeable acidity and pH of the soil.
Water has a high heat capacity because a lot of heat energy is required to break the hydrogen bonds found in a molecule of water. Because the majority of heat energy is concentrated on breaking the hydrogen bonds, the water molecule itself heats up after the bonds are b...
Pure or distilled water has relatively no buffering capacity. The buffering capacity of water can vary somewhat if the water comes from an impure source such as a river or pond.
Soil is home to thousands of living organisms, including moles, earthworms, centipedes, millipedes and grubs. Snails, beetles, ants, mushrooms and fungi also live in soil. Most of these organisms play a fundamental role breaking down remains of plants and animals, trans...
