Green house production depends or reliable substrates and fertilizers. Peat is the dominating substrate in Sweden and internationally. There is a debate about reducing the peat use since the mining for peat may increase climate gas emissions and disturb sensitive ecosystems. Thus, alternative for peat replacement or for peat mixes is explored. Trials has revealed that the solid part of biogas digestate may be a useful candidate, especially since biogas production is increasing and plays an important role in the bio based society. This residue has physical properties resembling peat and is rich in plant nutrients. The project will study how pre-treatments and maturation affects the quality of the digestate for substrate use concerning nutrient availability and physical properties. Secondly, extensive growth trials with herbs and lettuce will be performed with different ratios of peat and digestate. Finally the used potting substrate will be evaluated as a compost in mushroom production.
Växthusproduktionen är beroende av tillförlitliga substrat och gödselmedel. Torv är det dominerande substratet i Sverige och internationellt. Det pågår diskussioner om begränsad användningen av torv då brytningen kan ge ökning av klimatgaser samt störa viktiga ekosystem. Därför undersöks alternativ att ersätta, eller blanda in i, torvsubstrat. Studier har visat att den fasta delen av restprodukter från biogastillverkning kan vara en lämplig kandidat, speciellt som biogasen är på frammarsch och en viktig del i det biobaserade samhället. Denna restprodukt har fysikaliska egenskaper liknande torven och är även rik på tillgängliga växtnäringsämnen. Projektet avser att studera förbehandling och mognadens betydelse för växtodling i substratet vad gäller näringstillgänglighet och fysikaliska egenskaper. Därefter ska omfattande provodlingar av örter och sallat göras med olika blandningsförhållande torv/biogasrest. Slutligen ska det använda substratet utvärderas som substrat för svampodling.

There is an increasing interest in biochar for soil improvement, as carbon sink and as feed additive. Biochar has the ability to bind aflatoxins and anti-nutritional substances in feed and can also bind to certain bacteria, and thereby improve chick performance and health. Biochar can reduce …
