Why Mid America Compost Co. Worm Castings as opposed to “store bought” fertilizer?

Three main reasons for this: First, Worm Castings are proven by science to be just as good if not better for plants than store bought fertilizers. Studies from scientist at the EPA and USDA support the positive effects of using Worm Casting as an Organic Fertilizer over “store bought” fertilizers. Second, Using Worm Castings supports U.S. Recycling and reduces our solid waste impact as a country. There is really no use fighting for the protection of our soil (the USA) if we continue to pollute it.  Governments, Local Business, Churches, and Universities across the country seldom agree on any ONE thing. But on this, the idea of reducing our waste as a country and damaging our soil; is the ONE idea that is grossly supported by all. Lastly, Cost. Since Worm Castings from MidAmerica Compost Co. can offer potted plant nutrition for up to 6 months while also providing water retention, Gardeners and Farmers can save bundles of money by NOT purchasing traditional fertilizers that will dissolve after the first watering.

What makes MidAmerica Compost Co. Worm Castings different or better than other Companies?

Our approach to the production of Worm Castings is very much like that of any commercial production except for ONE main difference: Feedstock. Most Commercial producers of Worm Castings generally all use one, or possibly two, types of feedstock. This is usually whatever they can get the cheapest and the most readily. MidAmerica Compost Company’s feedstock is a balance of Nitrogen rich materials and Carbons. We start our natural feedstock (leaves, old garden plants, spoil veggies) in “vessel” composters. Then, after the compost has broken down and the appropriate temperature and pH balance has been achieved, we move this feedstock to the worms. The compost from the vessel composter is mixed again with the new food scraps from local coffee shops and sandwich shops and the worms are allowed to feed. This approach offers the worms an optimum diet and habitat which in turn yields a finer, more balanced, and healthier load of Worm Castings.
