Due to sandy soils (70%) and climate, Poland has problems with soil acidification. Over 4 million hectares have a pH in KCl below 5.0 – such soils can be considered degraded – they have a damaged structure, plants are not able to absorb nutrients, which leads to water pollution. An additional problem is the fact that most of the acidic soils are owned by small farms. The practice consists of a wide action of soil pH analysis, establishment of liming programs and reimbursement of part of the costs from CAP funds – eco-schemes fertilization with liming.
