Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo.
Soil pH is a measurement of how acidic (sour) or alkaline (sweet) your soil is. The abbreviation "pH" stands for "potential hydrogen” and indicates the concentration of hydrogen in the soil. The higher the amount of hydrogen in the soil, the lower the soil pH.
Soil pH is the measure of soil acidity or alkalinity, specifically the inverse log of the Hydrogen ion concentration on a scale from 0-14. Neutral pH is around 7, with ‘acids’ being below 7 and ‘bases’ being from 7 to 14.
The acidity or alkalinity of soil is indicated by its pH measurement. Learn how to determine what your soil pH is and how having the correct soil pH benefits your plants.
Soil pH is the level of acidity or alkalinity in the ground. A simple pH test can determine the pH level in relation to the pH scale, and the results of that test will act as a guide for adjustments that need to take place within the soil.
A pH range of 6.0 to 7.0 favors growth of most crops, although some crops have specific acid or alkaline soil requirements to be productive. Understanding soil pH will help to understand the influences of soil chemistry and biology and how nutrient availability and soil organic carbon are impacted.
Soil pH is, therefore, described as the “master soil variable” that influences myriads of soil biological, chemical, and physical properties and processes that affect plant growth and biomass yield.
Soil pH is a measure of acidity or alkalinity, which affects ion solubility, microbial activity, and plant growth. In this lab, exercises are designed to measure the pH of soil samples collected in the areas of interest.
Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic.
Soil pH is the measurement of the degree of acidity (sourness) or alkalinity (sweetness) of soil. It is measured on a scale of 0 to 14, with lower numbers more acidic and higher numbers more alkaline. The value of 7.0 is neutral—i.e., neither acidic nor alkaline.
