|We have a mild clay-like soil. Grass does grow but not deep. I recently saw an article on liquid aerators, contaning humus? Do these help at all. I don't have the time or money to get compost or manure to cover the yard.
|I would suggest you consult with your local county extension to see if there are any independent scientific tests that show a benefit of using this particular product on the particular soil found in your local area. While any form of humus is likely to be beneficial, small amounts may not achieve the result you are hoping for especiall if you are starting with little or no quality topsoil. Often soil improvement requires a combination of core aeration (or initial tilling at the preplanting preparation stage) along with additions of organic matter and coarse sand to improve the soil to a point where grass grows well in it. Sometimes too you can use a different variety of turf grass with better results. Your county extension should be able to advise on what works best locally as well. They may also be able to help you develop an inexpensive maintenance program to help you improve your lawn.|
