Operations and Maintenance <br /> Continued <br /> D. General Maintenance Tasks for Turf Adjacent to Trails <br /> There are general tasks that relate to turf management along trails, but what do the tasks involve? The <br /> following are tasks that are associated with turf maintenance. These tasks will be performed to varying <br /> degrees depending on the level of maintenance required or assigned to the given trail. Section D describes <br /> the "Maintenance Variable" and how that affects O&M. <br /> Task General Description <br /> Soil Testing Relates to doing a complete soil analysis on individual sites to determine <br /> the soil structure and fertility. Both major and minor elements should be <br /> reviewed during the analysis. Ideally, 15 to 20 cores should be tested per <br /> mile of turf adjacent to trails for high use areas. Where time and budget <br /> are limited, 10 or so soil samples per mile of turf adjacent to trails can be <br /> combined together to give an average soil analysis reading for the length <br /> of trail. In either case, the samples should be random to ensure an <br /> accurate soil analysis. The results of the soil test serve as the baseline for <br /> determining fertility needs. Soil testing on a routine basis allows for <br /> prescriptive maintenance to take place on a trail by trail basis. <br /> Fertility Relates to the level of essential compounds and nutrients within the soil <br /> structure that foster growth and increase durability of turf grasses. The <br /> primary components in fertilizer include: <br /> • Nitrogen (N) --is the key element in the production of turf grass. It <br /> affects turf greenness, ability to recover from damage,root and shoot <br /> growth and density,resistance to disease, and drought tolerance. <br /> • Phosphate (P) —is the workhorse of the nutrition team and fosters <br /> energy transformation. It is extremely important in new seedling <br /> development. Since it is cold sensitive, the most severe deficiency of <br /> phosphate usually occurs in the spring and fall. <br /> Aeration Aeration fragments or loosens compacted soils to allow for the free flow <br /> of air, water, and soil nutrients within the soil structure. It is an <br /> extremely important maintenance function that cannot be overlooked if <br /> quality turf adjacent to the trail is to be achieved. <br /> ISSUED r � <br /> FOR REVIEW Master Trail Plan <br /> 0 <br />
