Testing Your Soil Why and How to Take a Soil-Test Sample
www.nrcs.usda.govA soil analysis can help farmers and gardeners answer these questions. A basic soil analysis provides informa-tion on two important soil characteristics: • Soil pH is a measurement on a scale from acid (low pH) to alkaline (high pH). Most soils are on the acid side of the pH spectrum. Good soils for crop produc-
Inherent Factors Affecting Soil pH - USDA
www.nrcs.usda.govPage 1 Guides for Educators Soil pH is a measure of soil acidity or alkalinity. It is an important indicator of soil health. It affects crop yields, crop suitability, plant nutrient availability, and soil micro-organism activity which influence key soil processes.

Changing pH in Soil - University of California, Davis
vric.ucdavis.eduthe ammonium form of nitrogen to the nitrate form that plant can use also depends on the soil pH. Soil pH should be checked periodically and consistent testing will indicate whether your pH-control program is working. Raising pH The ideal pH range for soil is from 6.0 to 6.5 because most plant nutrients are in their most available state. If a ...

www.agronomy.k-state.eduThe soil has three major horizons (Fig. 2). 2 “A” horizon is the top layer of the soil in which organic matter has accumulated from plant and animal residues and from which clay and chemical elements have been leached into lower layers. The “A” horizon, then, is the leached layer of soil. “B” horizon is the middle layer of soil into ...

www.uwsp.edu4. pH is a measure of how acidic or basic things are. We assign a number scale from 0 to 14 to things to tell us how acidic or basic they are. A pH of 7 is neutral, less than 7 is acidic like vinegar with a pH of 3.5, and more than 7 is basic like ammonia with a pH of 10. (When soil pH is basic, it is usually called “alkaline.”) a.
