A new study carried out at the University of Helsinki shows biochar can be a promising tool in mitigating the environmental impacts of agriculture also in Finland, as written by the university in a press release<\/a>.<\/p>\n\n\n\n

In his doctoral study, \u00a0Subin Kalu<\/a>\u00a0found that biochar addition to soil can reduce nitrogen leaching from agricultural soils to waterways, and reduce the emissions of N2<\/sub>O – a potent greenhouse gas.\u00a0<\/p>\n\n\n\n

Biochar boosts nutrients retention <\/h2>\n\n\n\n

The high specific surface area and porous structure of biochar can improve the retention of soil water and nutrients in the soil, and thus their availability to crops. Biochar can also alter the physical, chemical, and biological properties of soils which could eventually reduce greenhouse gas emissions and nutrient leaching. Whether these beneficial effects after a single application of biochar persist for the long-term, especially in boreal climates, has remained unknown so far.<\/p>\n\n\n\n

\u201cIt is also essential to find out the long-term effects of biochar before its widespread application to soils, to detect if biochar would have any detrimental effects because it is not possible to remove it once it has been applied to the soil,\u201d says\u00a0<\/strong>Kalu.\u00a0<\/strong>\u00a0<\/p>\n\n\n

Investment in renewables will help Lithuania go green – but agriculture must become more sustainable<\/div>
Being the first country to declare independence from the Soviet Union in 1990, Lithuania was also the first one to proclaim itself independent from Russian gas earlier this year. <\/div><\/div><\/div>\n\n\n

Enhancing soil carbon storage<\/h2>\n\n\n\n

Kalu studied the long-term effects of biochars in four different agricultural field experiments in southern Finland where biochars had been applied two to eight years ago. Kalu says, \u201cAlthough the effects of biochars were not consistent throughout these years, some improvements in plant growth were observed when the previous growing seasons were planted with legumes. This special biochar and pre-crop effect warrant further study\u201d.<\/p>\n\n\n\n

\u201cIn some cases, biochars showed tendencies to improve agricultural benefits such as increases in crop yield, soil nitrate retention, and plant nitrogen uptake while reducing the negative environmental effects such as decreases in soil N2<\/sub>O emissions and nitrate leaching\u201d.<\/p>\n\n\n\n

Even if the observed positive agricultural and environmental effects were not consistent in all fields in the long term, researchers detected no negative effects of biochar over the study periods. This indicates that the application of biochar in agricultural soils is a safe way of enhancing soil carbon storage.<\/p>\n","protected":false},"author":2084,"featured_media":512315,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[42],"tags":[61874,128507,42156,75245],"location":[53484],"internal_archives":[],"class_list":["post-401472","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-sustainability-nl","tag-biochar","tag-greenhouse-gas-emissions","tag-sustainable-agriculture","tag-university-of-helsinki","location-finland-nl"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/06\/11_1.php_-scaled.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on September 7, 2022","modified":"Updated on September 7, 2022"},"absolute_dates_time":{"created":"Posted on September 7, 2022 12:15 pm","modified":"Updated on September 7, 2022 12:15 pm"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Sustainability<\/a>"],"unlinked":["Sustainability<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["biochar<\/a>","greenhouse gas emissions<\/a>","sustainable agriculture<\/a>","University of Helsinki<\/a>"],"unlinked":["biochar<\/span>","greenhouse gas emissions<\/span>","sustainable agriculture<\/span>","University of Helsinki<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":[],"unlinked":[],"slug":"post_translations","name":""},"location":{"linked":["Finland<\/a>"],"unlinked":["Finland<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/401472","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/512315"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=401472"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=401472"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=401472"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=401472"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=401472"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
