The only farmer who owns the farm and production site.They have a Free Stall system (cows can walk around freely inside the cow house), and milking is done twice a day at 5:00 and 16:00. They have 180 cows, but 140 of the 180 can be used In addition, they have 5 outside contracted farms and the EM brand milk is produced at approximately 7 tons daily from 500 cows in total.

Compost Treatment:

During milking, the cows are moved to the milking house, manure is collected by bulldozer and transferred to a compost collection site. After 5% chicken manure is added, the manure is dried in a glass house, packed and sold at home centers. Also, the EM treated manure compost is sold to other farmers, and the manure quality is so high that they often run out of stock.

Location: EM Tamaki Farm. Nanjo City, Okinawa. Japan.

EM Application

Drinking water : EM-A is applied at 5,000 to 10,000 times dilution rate into the drinking water treated with EM-X Ceramics. Feed : EM Bokashi made from EM, rice bran, molasses and
oligosaccharide, is used after 40 days of fermentation. 300g per cow per day.

Watering in the cow-house : Sprinkling of water EM-A at 5,000 – 10,000 times dilution rate is done when the  temperature is high or when odd odors occur.


The free Stall system can make it easy to clean the house. As a result, management cost including labor cost can be cut down. After cleaning, sawdust is applied on the floor to avoid slipping. Blue IC chips set around the cow’s neck, are used for cow control management, including milking and health measurements.

Effects & Results

Okinawa prefecture, located in the southern part of Japan and in a sub-tropical climate zone, is not suitable for the dairy business. However, thanks to EM, production rate is higher than for conventional farmers. There is no complaint of odor from neighborhoods which are increasing rapidly in population. It takes one year to confirm the effects of EM after the use of EM begins. The remarkable effects are as follows: decrease in odd odors, decrease in Mastitis (no cow had Mastitis during this interview), and increases in the fertilization ratio and production. Meanwhile, flies decreased to 1/4.
