Milorganite Lawn Fertilizer

A conventional grass lawn can have a large environmental footprint, from the large amount of water needed to keep it green, to the fossil fuel usage and air pollution associated with mowing it. As we have mentioned in earlier articles, planting 'no mow' and drought-resistant grass can greatly reduce these environmental inputs.

But any kind of lawn or grass is going to benefit from regular feedings of fertilizer to keep the grass strong and healthy. And that's another environmental impact that needs to be considered if you want your grass lawn to be as 'green' as possible.

The Dark Side of Conventional Synthetic Fertilizers

Most commercially available lawn fertilizers on the market today are synthetic (also called 'chemical' or 'inorganic').

Synthetic fertilizers typically contain blends of nitrogen, salts, minerals, and other chemicals designed for lawns.

While a healthy lawn requires many of these, synthetic fertilizers have a number of environmental drawbacks.

Back to Nature with Milorganite Lawn Fertilizer

There are plenty of all-natural fertilizers on the market today that can alleviate all of the drawbacks of synthetic fertilizers while still keeping your lawn green and healthy. Most natural fertilizers are made from animal manures or other by-products of the agricultural industry.

One of the best-selling, most widely available all-natural fertilizers is Milorganite Lawn Fertilizer. And you might not believe where it comes from.

The Milorganite Lawn Fertilizer Story

In 1919, the city of Milwaukee, Wisconsin adopted a new process for dealing with its wastewater. Air is allowed to bubble through wastewater for a set period of time. After the air is turned off and the waste mixture settles, the water was purified. This process was called the activated sludge process.

One drawback of this new process was the large amount of leftover solids, the microbes left behind by the treatment process. At the time, the city of Milwaukee was creating 70,000 tons of dried microbe waste a year, too much to simply send to a landfill.

Early on, a professor at the University of Wisconsin College of Agriculture studied this solid waste, determining that it was 6.2 percent nitrogen, 2.65 percent phosphate and 0.4 percent soluble potash, all comparable to commercial fertilizers of the day. Experiments with vegetables and field crops, then on the fairways at Maple Bluff Country Club in Madison found this solid waste to be superior to other fertilizers at one third the cost. It also did not burn the plants with over-application, and it produced a dark, thick green turf of grass. And Milorganite was born!


Milorganite gained its commercial name from a contest in 1925, and the Milwaukee Sewage Commission started selling Milorganite in late 1925.
