Dynamic Ressource Management: Contribution of the Chlorophyll-a Monitoring in Karstic Systems - Case Study

Main goals: Characterize a karst system exploited by springs and wells Characterize the surface karst water connections Results: Well on the Drain Annex System (DAS) Sping on the main karstic Drain (D) Opportunities: Inversion monitoring (estavelle) and dynamic pumping management in karstic systems ...

Creeping bentgrass color and quality, chlorophyll content, and thatch–mat accumulation responses to summer coring

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 ...

Luxury production of leaf chlorophyll and mid-season recovery from nitrogen deficiencies in corn

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 ...

How Phytoplankton Endangers Fish Farms - and the Best Way to Combat the Threat

Did you know that 99 percent of all biomass in the ocean is invisible to the human eye? To help put that in perspective, a teaspoon of seawater can hold over a million different living organisms – all tiny, often single-celled. Among them are phytoplankton – essentially the ocean’s microscopic plants and the foundation of the largest food chains on the planet. While too tiny ...

The US EPA Lake Erie indicators monitoring program 1983 - 2002:trends in phosphorus, silica and chlorophyll a in the central basin.

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 ...
