EM-1 Effective Microorganisms Concentrate


EM•1 ® Microbial Inoculant is basically a liquid probiotic for the soil. The microbes introduced by EM•1® support the growth of other beneficial organisms including mycchorrizae, earth worms, and insects already in your soil and plants. Since it is not a fertilizer, you still need to use fertilizers. Microbes make the fertilizers work better and make them available for plants to use. This means you can use about half the amount of fertilizer than you would normally use. EM•1® Microbial Inoculant is an excellent compost accelerator.

Since microbes convert organic matter to a usable food source for plants, fruits and vegetables will not only taste better, they will be more nutritious, and last longer. Beneficial microbes also produce lots of polysaccharides, glues that hold the soil together and hold in moisture, improving drought resistance.
