Joann K. Whalen focuses on Agronomy, Soil water, Soil organic matter, Manure and Earthworm. Her Agronomy research is multidisciplinary, incorporating perspectives in Leaching, Temperate climate, Mineralization, Crop residue and Loam. The concepts of her Soil water study are interwoven with issues in Environmental chemistry and Nitrification.
Her Soil organic matter research integrates issues from Agroforestry, Organic matter, Agroecosystem, Soil fertility and Tillage. Her studies in Manure integrate themes in fields like Fertilizer, Organic fertilizer, Irrigation, Cation-exchange capacity and Green manure. Her study in Earthworm is interdisciplinary in nature, drawing from both Biodiversity and Chemical composition.
Joann K. Whalen mostly deals with Agronomy, Soil water, Earthworm, Manure and Fertilizer. Her Agronomy research includes elements of Soil organic matter, Agroecosystem, Loam and Mineralization. Her Soil organic matter study integrates concerns from other disciplines, such as Agroforestry and No-till farming, Soil fertility.
Joann K. Whalen has included themes like Environmental chemistry, Organic matter and Nitrification in her Soil water study. Within one scientific family, she focuses on topics pertaining to Irrigation under Manure, and may sometimes address concerns connected to Environmental engineering. Her studies deal with areas such as Soil biology and Human fertilization as well as Fertilizer.
Joann K. Whalen mainly focuses on Agronomy, Soil water, Earthworm, Ecology and Agriculture. Joann K. Whalen has researched Agronomy in several fields, including Agroecosystem and Temperate climate. The various areas that she examines in her Soil water study include Environmental chemistry, Biodegradation, Lignin and Pulp and paper industry.
Her study in the fields of Aporrectodea under the domain of Earthworm overlaps with other disciplines such as Global distribution. Her Manure study combines topics from a wide range of disciplines, such as Lolium multiflorum, Crop, Nitrogen fertilizer, Cover crop and Nutrient. Her work carried out in the field of Tillage brings together such families of science as Loam, Nitrate and Green manure.
The scientist’s investigation covers issues in Agronomy, Soil water, Ecosystem, Ecology and Surface runoff. Her Agronomy research incorporates elements of Nutrient and Temperate climate. Her work deals with themes such as Environmental chemistry, Extraction and Hordeum vulgare, which intersect with Soil water.
Her research integrates issues of Soil biology and Earthworm in her study of Ecosystem. Her work in Earthworm addresses subjects such as Abundance, which are connected to disciplines such as Biomass.
