The authors estimated nitrogen transferral rates through the soil food web and calculated nitrogen mineralization rates for a range of soil organisms. In another landmark study, researchers from the Lovinkhoeve Experimental Farm in the Netherlands examined the flow of carbon and illustrated transfer rates with arrows of different thicknesses.
Elaine Ingham is an American microbiologist and soil biology researcher and founder of Soil Foodweb Inc. She is known as a leader in soil microbiology and research of the soil food web , [ 1 ] [ 2 ] She is an author of the USDA 's Soil Biology Primer .
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Plant and Soil is a monthly peer-reviewed scientific journal covering research on the relationships between plants and soil, such as relationships and interactions of plants with minerals, water and microbes, the anatomy and morphology of roots, soil biology and ecology, etc.
Acta Agriculturae Scandinavica. Section B. Soil and Plant Science is a peer-reviewed scientific journal published by Taylor & Francis on behalf of the Nordic Association of Agricultural Scientists. It covers environmental sciences, botany, earth sciences, physical geography, ecology, and the soil sciences of relevance to agriculture.
The soil is home to a large proportion of the world's biodiversity.The links between soil organisms and soil functions are complex. The interconnectedness and complexity of this soil 'food web' means any appraisal of soil function must necessarily take into account interactions with the living communities that exist within the soil.
The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way ...
Agricultural soil science studies the chemical, physical, biological, and mineralogical composition of soils as they relate to agriculture. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. Emphasis continues to grow on the importance of soil sustainability.
