Coring is a common cultural practice used on golf courses. The reported effects of coring alone on thatch–mat accumulation have been mixed. The objectives of this field study were to examine the effects of spring and summer coring on thatch–mat thickness and organic matter accumulation in creeping bentgrass (Agrostis stolonifera L.). Turfgrass color and quality and chlorophyll content were also ...

Deficiencies of N during the growth of corn (Zea mays L.) are often diagnosed by using chlorophyll meters that measure chlorophyll content in leaves. The diagnoses are based on the assumption that above-optimal supplies of N do not significantly influence chlorophyll meter readings (CMRs). The objective of this research was to assess the possibility that above-optimal supplies of N impacted ...

During the past 20 years, Lake Erie has exhibited a series of complex chemical changes resulting from changing anthropogenic influences and introductions of exotic species. Since 1990, some apparent trends in nutrient concentrations have been inconsistent with the predictions of models originally used to guide Lake Erie water quality management. We performed time trend analysis on total ...
