Roseville Soils Testing Annual Report: Year 1 <br />December 29, 2022 <br />Page 2 <br />Soil Testing Results <br />Soil testing occurred after one spring thaw (June) and after one year (October). Fertility and health tests were sent to two <br />different labs: The University of Minnesota and Ward Labs (Nebraska). Soil structure, color, and plant growth were <br />observed in the field. Infiltration testing was also completed in the field. <br />Soil Organic Matter: <br /> Minnesota Lab - Loss on Ignition (%) <br />vegetation <br />Site Site Description management 10/15/2021 6/13/2022 10/10/2022 <br />Њ ƭǞğƌĻ ƓğƷźǝĻ Ћ͵А Ћ͵Ў Ћ͵Џ <br />Ћ ƭǞğƌĻ ĻķŭĻ ƷǒƩŅ Ћ͵Љ Ќ͵А Ќ͵Њ <br />Ќ ƷƚƦ ƚŅ ĬĻƩƒ Ώ ĭƚƒƦƚƭƷ ƓğƷźǝĻ Ћ͵Б Ћ͵В Ќ͵Њ <br />Ѝ ƷƚƦ ƚŅ ĬĻƩƒ Ώ /hbwh\[ ƓğƷźǝĻ Ћ͵Ћ Ћ͵Ѝ Ћ͵Ћ <br />Ў ƷƚĻ ƚŅ ƭƌƚƦĻ Ώ ĭƚƒƦƚƭƷ ƷǒƩŅ Ќ͵Б Ѝ͵Ћ Ў͵Б <br />Џ ƷƚĻ ƚŅ ƭƌƚƦĻ Ώ /hbwh\[ ƷǒƩŅ Ќ͵Љ Ќ͵Ћ Ќ͵Ћ <br />Percent organic matter is considered good for plant establishment at 3%. <br />years. That said, the trends seem to indicate a greater increase in organic matter in areas with compost top-dressing. <br />Soil Structure & Color: <br />Topsoil is variable here, depending on the composition and mixing with the fill materials. Sandy Loam topsoil had loose <br />single grained structure and loam topsoil had strong blocky structure. A drought in the last half of summer dried the soils <br />a lot, baking the loams into strong blocky bricks and causing the sandy soils to collapse around the holes. It is hoped that <br />continued composting efforts will lead to moderate granular structure in any soil texture. <br />Change in soil color was not observed after one year. Topsoils remained at 10YR 3/2 or 10YR 2/2 in the Munsell Soil <br />Color Book (very dark grayish brown or very dark brown). Soil color change might not be detectable in the three year <br />study time-frame. <br /> <br />Qbhf!6!pg!63 <br /> <br />
