Abstract
Response of canola (Brassica napus Invigor 5030) and wheat (Triticum aestivum Prodigy) to
biochar amendments was examined in a controlled environment experiment. A Brown
Chernozem soil was amended with two types of biochar (wheat and willow biochar) at 1 and 2 t
ha-1 alone and in combination with N and P fertilizer. Canola was grown in amended pots in
controlled environmental conditions over a four week period. Parameters evaluated were
germination and biomass yield, soil organic carbon, above ground nitrogen and phosphorus
uptake and % recovery of applied N and P after 4 weeks of growth. The addition of biochar alone
had limited impact on biomass yield (Fig 2, 3, 4 and 5). Addition of fertilizer, especially N,
significantly (p<0.05) increased canola yield. The calculated plant recovery of applied fertilizer
was often increased by biochar addition at the 1 T/ha rate.
