Abstract We tested the effects of Galena or Chinook hops treatment (6% wt/wt) simulated composts (13 d) wood chip litter (WCL) alone mixed 3:1 with ground Bluestem hay (BSH). Results revealed that net losses urea and ammonia in WCL composted without BSH (n = 3/treatment) were unaffected by (P 0.37 0.13, respectively), averaging 0.32 ± 0.7 0.03 1.5 µmol/g, respectively). The loss uric acid was 6...

Rice husk ash (RHA), palm oil mill effluent (POME) sludge, and decanter cake can be utilized as compost to reduce environmental pollution. This research attempted investigate the effect of RHA addition oil-based in boosting nitrogen (N) uptake growth Brassica oleracea var. <i>alboglabra</i> L. (Chinese kale plant).
