Mop crops are plants that are used in effluent management to reduce runoff into waterways and other environmental systems.
Agricultural or environmental crops, which are cultivated in “sewage farms”, are irrigated with sewage effluent to prevent effluent from moving into waterways. Hemp, being a lightweight plant that has great tensile strength and thermal properties, can absorb effluent and sewage that would otherwise go into nearby waters and hurt the ecosystem.
Mop crops can be used to clean domestic, agricultural, or industrial wastewater. With the use of mop crops, wastewater can provide valuable nutrients which are absorbed and converted into plant biomass.
The root zone of the mop crop is effective at removing pollutants and protecting groundwater. These plants can even be harvested and used to make economic products. Mop crops are also used to remove excessive phosphorus and other chemicals from chicken litter, remove toxins and pollutants from soil, and restore the depleted soil.
Mop crop plantations can produce valuable environmental benefits like ecological integrity and carbon sequestration and act as an economic resource.
