Site characteristics determine the duration of structure liming effects on clay soil

open access: yesAgricultural and Food Science, 2022
Adding carbonated or non-carbonated lime to clay soils can lead to changes in aggregate stability. In Sweden, ‘structure liming’ with a mixed product (normally 80–85% calcium carbonate and 15–20% calcium hydroxide) is subsidised through environmental ...

Early effects of helicopter liming on soil and vegetation in two acidified forest stands in Nova Scotia, Canada

open access: yes, 2022
Increased fossil fuel burning in the 1900’s caused high levels of acid deposition in northeastern North America. Acid deposition depletes soil base cations and increases toxic aluminum concentrations.

Soil acidification and the importance of liming agricultural soils with particular reference to the United Kingdom [PDF]

open access: yes, 2016
Soil acidification is caused by a number of factors including acidic precipitation and the deposition from the atmosphere of acidifying gases or particles, such as sulphur dioxide, ammonia and nitric acid.

The Diversity of Phaseolus-Nodulating Rhizobial Populations Is Altered by Liming of Acid Soils Planted with Phaseolus vulgaris L. in Brazil

open access: yes, 2002
PCR-mediated restriction fragment length polymorphism (RFLP) analysis of the 16S-23S rRNA internally transcribed spacer (ITS) region and the 16S rRNA gene indicated that the rhizobial populations isolated from common bean (Phaseolus vulgaris L.) nodules ...

Experiences with liming in European countries - results of long-term experiments

open access: yesJournal of Forest Science, 2006
Liming was and still is carried out in many European forests since the beginning of the 1980s. Main objectives of compensation liming is to neutralize actual acidic deposition in order to prevent further soil acidification, to increase base saturation ...
