Liming to Improve Soil quality - USDA
www.nrcs.usda.govSoil pH is an excellent chemical indicator of soil quality. Farmers can improve the soil quality of acid soils by liming to adjust pH to the levels needed by the crop to be grown. Benefits of liming include increased nutrient availability, improved soil structure, and increased rates of infiltration. This technical note addresses the following ...

Poor soil structure can restrict crop growth and results in poor nutrient use efficiency. 4. Carry out soil analysis for pH, P, K and Mg every 3–5 years (page 19). Target values to maintain in arable rotations are: • Soil pH 6.5 (5.8 on peat soils) • Soil P ...
