A method of combined intercropping and mulching of commercial crops is described herein. Suitable annuals such as young wheat and/or buckwheat plants are planted in soil in which legumes were originally planted. A portion of the resulting upper portions of young wheat and/or buckwheat plants is mowed and blended with organic debris to provide nutrients for intercropped commercial plants such as corn and soybeans. The remaining portion is chopped blended with organic debris and sprayed onto the top layer of seeded soil as combination mulch. For larger commercial applications, conventional agricultural machines are described herein, and are modified for the most efficient intercropping. For best results, at least one intercropped commercial plant should be a legume.

Novel methods and apparatuses are disclosed for the treatment of wastewater to reduce, often associated, offensive odors. Irrigation of oxygenated liquid on top of a permeable cover effectively creates an aerobic treatment zone at the top of the lagoon whereby odorous gases being produced anaerobically below the cover are metabolized within this zone before being released to the atmosphere. This same system also serves to increase evaporation from the overall waste handling system therefore substantially reducing or eliminating the need for land application of treated wastewater.
