The IPNC is organised by the International Plant Nutrition Council, which "seeks to advance science-based non-commercial research and education in plant nutrition in order to highlight the importance of this scientific field for crop production, food security, human health and sustainable environmental protection".

Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
The Department of Geography and Geology was established in 2007 by merging the two, former separate departments at the University of Copenhagen. The Department for Forest, Landscape and Planning was established in 2004 by a merger of the former public research institute Forest & Landscape, the Department of Economy, Forest and Landscape at KVL ...
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...
As the contact time between the contaminant and soil increases, a decrease in bioavailability is observed, termed “ageing”, due to diffusion and sorption processes with mineral and organic fractions of soil. [5] Environmental conditions influence bioavailability. Drought conditions result in lower soil water content. This can reduce the ...
