We present water quality data from 58 coastal wetlands, sampled as part of a larger effort investigating effects of nutrient enrichment and habitat disruption in the Laurentian Great Lakes. Our sampling design selected sites from across a gradient of agricultural intensity within combinations of biogeographic ecoprovince and wetland hydromorphic type and captured a large range in water quality....
A field experiment was carried out at AICRP on Weed Management Research Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif 2020-21. Fertigation is the technique supplying dissolved fertilizers to crops through an irrigation system.The laid in split plot design with three replications and twenty treatment combinations having four different fertigation lev...
PURPOSE Elderly people are at risk for malnutrition, and those who consume a puréed diet may be particularly at risk. A fortification procedure was developed at a long-term care (LTC) facility, and nutrient intakes and serum vitamin levels were assessed to determine whether they subsequently increased. METHODS Fortification levels were determined using a combination of two techniques: the Die...
Changes in land use may lead to increased soil nutrient levels in many ecosystems (e.g. due to intensification of agricultural fertilizer use). Plant species differ widely in their response to differences in soil nutrients, and for savannas it is uncertain how this nutrient enrichment will affect plant community dynamics. We set up a large controlled short-term experiment in a semi-arid savanna...
