The present invention provides for a growing medium having a mix of soil, graphene, and/or graphene oxide. In at least one example, soil is combined with single or few layer graphene. In another example, the soil is combined with single or few layer graphene, including graphene sheets, and graphene oxide. The growing medium has been shown to increase plant growth while providing for growing medium aeration, increased water retention, and increased nutrient loading and release.

The present invention provides for nutrient extraction and recovery devices that use the Donnan Membrane Principle (DMP) to cause spontaneous separation of dissolved ions along electrochemical potential gradients, wherein anions and cations such as H.sub.2PO.sub.4.sup.−, HPO.sub.4.sup.2−, PO.sub.4.sup.3−, Mg.sup.2+, Ca.sup.2+, NH.sub.4.sup.+, and K.sup.+ are moved from manure containing waste streams through cation and anion exchange membranes into a recovery stream thereby precipitating target compounds including but not limited to struvite, potassium struvite and hydroxyapatite.
