Surfaces and methods for producing surfaces that may support an artificial
playing surface are disclosed herein. An example of a surface according
to the invention includes a first layer with soil and a plurality of
fibers, and a second layer with soil and an organic binder. At least a
portion of the second layer is above the first layer. Both layers should
be water permeable to some degree. The organic binder may include
material from plants of one or more of the plantago family (such as dried
and ground plantago husk) and/or guar family.
