Strongly acidic soils may present several problems for wheat production. These include aluminum toxicity and, in some cases, manganese toxicity, as well as deficiencies in phosphorus, calcium, magnesium, and molybdenum. Where acid soils are reducing wheat production, liming the soils and raising the pH to an optimum range can significantly improve yield.
Correcting acidic soil conditions by applying lime can significantly impact crop yields, especially for alfalfa. Acidic soils can significantly reduce nodule establishment and activity in alfalfa. Liming is one of the most essential but often overlooked management decisions a producer can make for alfalfa production.
