Editing Alnus cordata (section)

==Cultivation==
Like other alders, it is able to improve soil fertility through symbiotic [[nitrogen fixation]] with the bacteria ''Actinomyces alni'' (''[[Frankia alni]]'').<ref name="Ducci-2009">{{cite journal|author1=Ducci, F.|author2=Tani, A.|title=Italian alder - ''Alnus cordata''|journal=EUFORGEN Technical Guidelines for Conservation and Use|date=2009|url=http://www.euforgen.org/fileadmin//templates/euforgen.org/upload/Publications/Technical_guidelines/1370_Italian_alder__Alnus_cordata_.pdf|access-date=2016-10-19|archive-date=2016-08-11|archive-url=https://web.archive.org/web/20160811032417/http://www.euforgen.org/fileadmin/templates/euforgen.org/upload/Publications/Technical_guidelines/1370_Italian_alder__Alnus_cordata_.pdf|url-status=dead}}</ref> It thrives on much drier soils than most other alders, and grows rapidly even under very unfavourable circumstances, which renders it extremely valuable for landscape planting on difficult sites such as [[mining]] spoil heaps and heavily compacted [[urban area|urban]] sites. It is commonly grown as a [[windbreak]] which helps with soil protection.{{citation needed|date=March 2023}}<ref>{{Cite book |last=Caudullo, G. |first=Mauri |title=Alnus cordata in Europe: distribution, habitat, usage and threats. |publisher=Off.

''Alnus cordata'' is regarded as a desirable candidate for bioremediation due to its presence in an ecosystem being associated with beneficial effects such as increased amounts of organic carbon and nitrogen-rich litter.<ref>{{Cite journal |last1=Villani |first1=Fiorella |last2=Castellana |first2=Simone |last3=Beritognolo |first3=Isacco |last4=Cherubini |first4=Marcello |last5=Chiocchini |first5=Francesca |last6=Battistelli |first6=Alberto |last7=Mattioni |first7=Claudia |date=June 2021 |title=Genetic Variability of Alnus cordata (Loisel.)

===Bonsai===
The Italian Alder makes a medium to large [[bonsai]], a quick grower it responds well to pruning with branches ramifying well and leaf size reducing quite rapidly.<ref name="Ma-Ke_Alnus cordata ">{{cite web | first=Mark | last=D'Cruz | title=Ma-Ke Bonsai Care Guide for Alnus cordata | date=20 March 2020 | publisher=Ma-Ke Bonsai | url=https://www.makebonsai.com/post/italian-alder | access-date=2021-02-04}}</ref>
