• Depth to hardpans s Site conditions of>40"are considered to have slight limitations Site conditions of 20"to 40"are considered to have moderate limitations Site conditions of<20"are considered to have severe limitations Based on the published information,soils 220,236,237 and 241 have hardpan from 20"to 40"from the surface which is considered to be moderate. Based on the published information,soils 102, 193 and 219 have hardpan greater than 60"from the surface which is considered to be slight. There were three soil boring taken at the site. These borings revealed that the hardpan layer ranges from 3.0' to 4.4'at TVI;0.0'to 2.5'at TV2;to 0.0't 3.5' at TV3. Considering that the site and the other cropping fields are to be leveled,causing deep cuts and fills, then ripped to a depth of 36",this particular category is for reference only.The properties have only recently been acquired by the teVelde family. The farming practices will change to cause a gradual improvement of the soil profile as a result of intense farming in conjunction with proper agronomic management. I would conclude that in some areas the hardpan will be covered to depths that will provide an impervious layer to percolation of surface water through to the ground water and in other areas it will have been cut, broken,moved or removed from the site in the form of rocks. • Depth to high water table: Areas with a high water table greater than 4 feet are considered to have only a slight limitation to the I application of agricultural wastes. 1 The depth to high water table varies from approximately 97'to 135'across the site and the adjacent I properties that are to be used to disperse the manure solids and nutrient water onto. It can be concluded that there will be no impact to the ground water do to the conditions of farming at this site. • Water intake rate,hydrologic soil group: Soils classified as group D are considered to have moderate limitations All soils at the site and properties to be used to disperse manure solids onto are all classified into group D. The limitations are a result of the slow infiltration and potential runoff from rainfall or irrigation. These properties are being leveled and are having irrigation pipe lines,field runoff collection and return pipelines with pumps installed to properly collect and recycle field runoff waters. • Flooding: The site and surrounding properties are within flood zone C. This zone does not experience flooding. • Permeability rate,inches per hoar: High solids waste and liquid wastes applications onto a site with a rate of<2.0"is considered to have slight limitations All of the soils have a published permeability rate of<2.0 inches. • Soil pH: Site conditions of>6.5 are considered to have slight limitations Site conditions of 3.5 -6.5 are considered to have moderate limitations Site conditions of<3.5 are considered to have severe limitations k + The published pH for the site and dispersal soils vary from 5.1 to 8.6,slight to moderate limitations. The actual test results of soil samples range from 6.1 to 8.1,slight limitations to applications of agricultural waste. Very high application rates of manure can lower soil pH.
