What Our Clients Are Saying
“We have used WormGro on some of our commercial lucerne hay crops on a 16-acre black clay soil plot… After the application of 20L/ha WormGro, we needed only two waters (previously it needed four) and saw a 25 percent increase in yield just 3 weeks later. Of relevance, the quality of the plants has also improved and they look considerably stronger and healthier. On just 16 acres in three weeks, that was a net difference (exc. farm overheads) of $6,054 with WormGro and $5,000 without or a 121 percent uplift after three weeks.”
