This is year two of my using EM-1

This is year two of my using EM-1. I am happy to say that the production of fruit is remarkable as it appears that every bloom sets and the size of fruit is wonderful. I use this product weekly on my plants. I share this information with all my gardening friends.

Thank You Dr. Higa

EM-1 is the best product we have ever used on our farm! Your soil will never be healthier and your crops will flourish. We are a small garlic grower and this year our yield is off the chart!

This stuff is awesome!

This stuff is awesome! Activate EM-1 and it goes a really long way. It's the best Microbial additive on the market in my opinion. The uses for it are almost unlimited. If you've not tried it and you want healthy plants, grass, flowers or anything else that grows, you're missing out big-time! Period!

High Quality - Careful Packing

“We did a 50% reduction of Nitrogen using the EM Nitro protocol on 30 acres, the yield looks great and will for sure go with EM nitro for next year."

The best corn in years

I put EM NITRO on top of my nitrogen program and after the first application of EM NITRO my corn greened up significantly. In terms of color, I can confidently say it’s some of the best corn in years.
