As the pressure mounts for clime - neutral horticulture and high - operation substrate , Klasmann - Deilmann has long been introduce renewable sore materials into their substrate preparation . TerraCoal ® , a biochar - based material , stage a further addition to this portfolio .
" With TerraCoal ® , we ’re not only adding a novel material , we ’re introducing one with unique properties that better plant execution while actively lead to foresighted - term C requisition , " Johanna Heim , Technical Manager for the Biochar Department at Klasmann - Deilmann , explain .
Technically utter , TerraCoal ® is characterized by its fine holey structure , which extend several central benefits when used in greenhouse substrates . Johanna shares that it avail with nutrient buffering , where the stomate in the biochar human activity as adsorption sites , helping to retain nutrients during irrigation and plant food program and discharge them lento over time .
" Improved water retentivity is another reward . Its porousness also give to better pee - admit capacity , foreshorten irrigation frequency and fend for plants during wry - down periods , " she add .
TerraCoal ® is also extremely dimensionally static , add morphological constancy . " It does not cheapen like organic fibers or shrink over time , therefore continue air - filled porousness and source - geographical zone aeration throughout the cropping cycle , " she shares . " Another object lesson of its benefits is carbon permanence . Unlike other organic materials , TerraCoal ® locks carbon in a stable form for 100 to thousands of years , aid growers meet CO₂-reduction targets through the substrate alone . "
" It ’s the compounding of horticultural functionality and mood carrying out that makes TerraCoal ® stand up out . "
Integration into growing medium : tried and testedGreenhouse grower are justly conservative about raw bare-ass materials , particularly in high - value crops like fruit vegetables and soft yield . But Johanna punctuate that TerraCoal ® has been rigorously tested and carefully integrated into substrate mix without compromising harvest performance .
" Every new material we use must encounter our core touchstone : compatibility , safety , and added value for industrial plant cultivation , " she says .
Substrates containing TerraCoal ® are presently being essay and apply across a kitchen stove of crops with promising answer . Johanna shares that in the Netherlands , intensive glasshouse organisation are trialing TerraCoal ® Growbags in the cultivation of love apple and peppers , supporting the sector ’s challenging goal of achieve climate neutrality by 2040 . In soft yield production , visitation with strawberry are focalize on key aspects such as ancestor ontogenesis , moisture management , and substratum seniority while targeting pH.
Ornamental growers are also exploring TerraCoal ® for its structural stableness and buffering capacity , which contribute to consistent ontogenesis and high - lineament resultant in long - round flowering crops . to boot , TerraCoal ® has already been commercially adopted in Basil of Caesarea refinement , prove particularly effective in retail pot herb production , where the ware ’s sustainable value resonates with environmentally conscious consumers .
Carbon sink voltage : A new province for growersAccording to Johanna , one of the most authoritative messages for greenhouse growers is that using TerraCoal ® means participating in a larger carbon paper cesspit ecosystem . This require a new mindset around substrate administration .
" Once the crop Hz terminate , how you handle the used substrate determines whether TerraCoal ® ’s carbon remain interlace or is turn . " Klasmann - Deilmann is promoting shut - loop system , peculiarly with their Growbags . These are retrieved post - harvest and institutionalize for composting or agricultural reuse , see to it the C remains in the soil rather than being incinerate or landfilled .
However , in more undetermined system where substrate reach the end consumer ( e.g. , potted herbs ) , education for proper end - of - lifetime disposal along the economic value concatenation is necessary .
" From producer to grower to retailer and even consumer , everyone has a part in secure TerraCoal ® ’s environmental benefit is keep up , " she says .
The name TerraCoal ® might leaven eyebrows , particularly given " ember ’s fogey fuel associations . " We ’re redefine ' ember ' " , Johanna simply states . " TerraCoal ® is not fossil - free-base as it ’s derived from woody biomass , a renewable and organic resource . The name reflects our intersection family line , like TerraActiv , and signal a new generation of carbon - rich , green cloth . "
