  2. Biofertilizer - Wikipedia

    en.wikipedia.org/wiki/Biofertilizer

    Compost is commonly used as biofertilizers. It can be used directly on the soil or by using compost-derived products such as extracts or compost-tea made by fermenting compost mass. Vermicompost-based innoculants proposed by permaculture methods, Korean natural farming and JADAM [13] are examples of biofertilizers.

  3. Biotechnology - Wikipedia

    en.wikipedia.org/wiki/Biotechnology

    Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non-food (industrial) uses of crops and other products (e.g., biodegradable plastics, vegetable oil, biofuels), and environmental uses. [32] For example, one application of biotechnology is the directed use of ...

  4. Azotobacter - Wikipedia

    en.wikipedia.org/wiki/Azotobacter

    In addition to being a model organism for studying diazotrophs, it is used by humans for the production of biofertilizers, food additives, and some biopolymers. The first representative of the genus, Azotobacter chroococcum , was discovered and described in 1901 by Dutch microbiologist and botanist Martinus Beijerinck .

  5. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    Food webs are limited representations of real ecosystems as they necessarily aggregate many species into trophic species, which are functional groups of species that have the same predators and prey in a food web. Ecologists use these simplifications in quantitative (or mathematical representation) models of trophic or consumer-resource systems ...

    Nitrogen is an essential element needed for the creation of biomass and is usually seen as a limiting nutrient in agricultural systems. Though abundant in the atmosphere, the atmospheric form of nitrogen cannot be utilized by plants and must be transformed into a form that can be taken up directly by the plants; this problem is solved by biological nitrogen fixers.

  7. Soil food web - Wikipedia

    en.wikipedia.org/wiki/Soil_food_web

    An example of a topological food web (image courtesy of USDA) [1]. The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals.

  8. Environmental biotechnology - Wikipedia

    en.wikipedia.org/wiki/Environmental_biotechnology

    Environmental biotechnology can simply be described as "the optimal use of nature, in the form of plants, animals, bacteria, fungi and algae, to produce renewable energy, food and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process". [3]

  9. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Organic fertilizers can also describe commercially available and frequently packaged products that strive to follow the expectations and restrictions adopted by "organic agriculture" and "environmentally friendly" gardening – related systems of food and plant production that significantly limit or strictly avoid the use of synthetic ...
