Roger M. Gifford spends much of his time researching Carbon dioxide, Agronomy, Botany, Ecophysiology and Stomatal conductance. His work deals with themes such as Sunflower, Horticulture, Organic matter and Nutrient, which intersect with Carbon dioxide. In his study, Photosynthesis and Respiration is inextricably linked to Dry weight, which falls within the broad field of Sunflower.
His Crop and Crop yield study are his primary interests in Agronomy. Botany is closely attributed to Animal science in his research. His studies examine the connections between Stomatal conductance and genetics, as well as such issues in Transpiration, with regards to Field capacity.
Agronomy, Carbon dioxide, Botany, Pasture and Ecology are his primary areas of study. His studies in Agronomy integrate themes in fields like Soil water, Soil carbon, Ecophysiology and Pinus radiata. His Soil carbon research incorporates themes from Soil organic matter and Soil horizon.
Roger M. Gifford has included themes like Sunflower, Organic matter, Plant physiology, Nutrient cycle and Poaceae in his Carbon dioxide study. His Botany research integrates issues from Nutrient, Phalaris aquatica and Animal science. His Photosynthesis research includes themes of Dry weight and Acclimatization.
Roger M. Gifford mostly deals with Agronomy, Pasture, Soil carbon, Pinus radiata and Themeda triandra. The concepts of his Agronomy study are interwoven with issues in Soil organic matter, Soil water and Climate change. The various areas that Roger M. Gifford examines in his Climate change study include Monoculture, Root length, Primary production and Root growth.
His Pasture study combines topics from a wide range of disciplines, such as Soil core, Grassland, Grazing and Animal science. Roger M. Gifford has researched Soil carbon in several fields, including Soil test, Nitrogen cycle, Litter, Afforestation and Soil horizon. His research integrates issues of Agroforestry, Tree planting, Ecosystem and Temperate climate in his study of Pinus radiata.
Roger M. Gifford focuses on Agronomy, Soil carbon, Soil test, Pasture and Pinus radiata. In most of his Agronomy studies, his work intersects topics such as Ecology. The Crop yield and Co2 concentration research he does as part of his general Ecology study is frequently linked to other disciplines of science, such as Food supply, Confusion and Econometrics, therefore creating a link between diverse domains of science.
Food supply overlaps with fields such as Climate change and Crop in his research. His studies deal with areas such as Soil horizon, Afforestation, Litter and Themeda triandra as well as Soil carbon.
