Conclusion

Humifirst WG increased Roots +6 %

Humifirst WG + Intake increased Roots +1.4 %

Unfortunately final Yield was not collected

The Agronomist and the Farm Manager both commented separately that the

treated Broccoli was the best blocks this year

Recommend repeat the trial so final yield can be calculated
