Whether mixed with feed, added to litter or used in the treatment of slurry, the positive effect of biochar very quickly becomes apparent. The health – and consequently the well-being – of the livestock improve within just a short space of time. As regards nasty smells and nutrient losses, the use of biochar could even herald a new age of livestock farming, closing agricultural cycles of organic matter. |
