Compost Tea Grows More Onions, Reduces Slug Damage!!!

But wait there's more!!!! More lettuce, and more chard too!!!  Actually, 58% more onions, 21% more lettuce, and 110% more chard  (that's a lot of chard, what in the world does one do with 110% more chard?).    And it's not just yields.... get this.... compost tea reduced slug damage on lettuce.... I will write that again.....compost tea reduced slug damage on lettuce.  Take a  moment if you need to. 

This groundbreaking study was done in collaboration between universities in Italy, Morocco, and Saudi Arabia (talk about a multicultural collaboration, we here at TeaLAB love it).   This collection of agri-scientists wanted to see if using compost tea in the rich volcanic soils of the Mediterranean helped to improve yields, shelf life, and pest control. 

An Actively Aerated Compost Tea was brewed for 48 hours, using a compost made from cow manure and plant waste.  The tea was then applied weekly as a foliar spray during the crop's entire growth cycle.  Yields and pest data were calculated at the end of the growing cycle.  Lettuce heads were placed in bags, and then into a refrigerator to see how long they would last.

As stated before, compost tea did the trick.  Higher yields, less slugs, and longer lasting lettuce.  What more could you ask for?  This is yet another study that shows us that brewing tea is worth the effort.  The slug data alone is reason to celebrate.  Thank you science!!!!
