Soil acidity is one of the most important soil factors affecting crop growth and ultimately, yield and profitability. It is determined by measuring the soil pH, which is a measure of the amount of hydrogen ions in the soil solution. As soil acidity increases, the soil pH decreases. Soils tend to be naturally acidic in areas where rainfall is sufficient to cause substantial leaching of basic ions (such as calcium and magnesium), which are replaced by hydrogen ions. Most soils in Kentucky are naturally acidic because of our abundant rainfall.

4-H Land Judging in Kentucky
3/30/2015 (major revision)

 UK Authors: David Ditsch, Josh McGrath, Bo
 Departments: 4-H Programs, Plant and Soil Sciences
 Series: 4-H Plant Science and Crops: Plant and Soil Science (4BA series)

Land judging is a way of appraising the physical nature and capability of soils. Certain soil properties, such as slope, depth and color, and others that can be seen, felt or measured, are reliable indicators of soil characteristics. This publication provides instruction on basic soil concepts that can be easily applied to agricultural, industrial, residential, and recreational land uses in Kentucky. It provides characteristics to be judged as well as a good working knowledge of soil.

Determining Soil Texture by Feel
1/22/2015 (new)

 UK Authors: Josh McGrath, Edwin Ritchey
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: soil and land

Soil texture refers to the proportion of sand, silt, and clay in a soil. Texture influences almost every aspect of soil use, both in agricultural and engineering applications, and even how natural ecosystems function. Many scientists consider soil texture the most important soil property as it can influence soil/water relationships, gas exchange, and plant nutrition. Accurately determining soil texture in a lab requires time and money; therefore, it is often necessary to estimate soil texture in the field by feel, which can be very accurate if done correctly.
