In acid soils the principal chemical form of potassium available for plant uptake is ____.

Question

Quizplus · Accepted Answer

In acid soils, potassium is primarily found in the form of K+ ions which bind with negatively charged components of soil particles such as clay and humus. These K+ ions can also react with other ions in the soil, such as H+ ions, to form compounds like KH2PO4 that are also available for plant uptake. Option C represents this form of potassium in acid soils, where K+ is bound to soil particles and is available for uptake by plants. The other options do not accurately represent the chemical forms of potassium in acid soils.
