• 4 000,109 Characteristically; the Georgeville like soil does contain appreciable quantities of clay material. The exchange capacity of the subsoil is high, while the sandy texture of the topsoil wid permit rapid movement of water into the soil profile. This rapid movement of water into the soil profile coupled with the high exchange capacity encountered in the subsoil renders these soils ideal as receivers for wastewater. Land Use The predominant land use on the proposed wastewater receiver site is pasture. If a permit is granted for a land treatment system, then the land must remain in either agricultural or silvicultural production. Forage and forest crops are ideal receivers for pretreated wastewater. Additional nutrients may be required on the site, however, if all forage crop is selected. The primary nutrient of concern is potash. Generally, the potassium level encountered in wastewater is significantly . lower than that required to meet the crop's need for potassium: Supplementation of the waste stream with potash and lime to adjust soil pH are necessary if the site is to be left in forage. Period soil testing is essential to- ensure that the recommended agricultural requirements for selected crops are met and that the site is operating within reasonable limits. Application Method The primary objective of slow rate spray irrigation is to alleviate or eliminate the surface discharge of pollutants. This is accomplished by irrigating pretreated wastewater at very controlled rates onto the surface of the soil where the nutrients present in the waste stream may be assimilated by the growing crop. Once wastewater is applied to the surface of the soil, it moves into and through the profile by processes called infiltration and percolation respectively. The waste application method most suited to this particular soil, vegetation, climatic, and topographic
