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.
Use of bio-solids in agricultural production is less common, and the National Organic Program of the USDA (NOP) has ruled that biosolids are not permitted in organic food production in the U.S.; while biologic in origin (vs mineral), sludge is unacceptable due to toxic metal accumulation, pharmaceuticals, hormones, and other factors. [32]
It has been found that food contamination from fertilizer is of little concern as plants accumulate little fluoride from the soil; of greater concern is the possibility of fluoride toxicity to livestock that ingest contaminated soils. [98] [99] Also of possible concern are the effects of fluoride on soil microorganisms. [98] [99] [100]
Biofertilizers are seen as promising, sustainable alternatives to harmful chemical fertilizers due to their ability to increase yield and soil fertility through enhancing crop immunity and development. When applied to the soil, plant, or seed these biofertilizers colonize the rhizosphere or interior of the plant root. Once the microbial ...
Biostimulants also termed as plant conditioners or bioeffectors are substances, cultures of micro-organism, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers. They do not include pesticides or fertilizers.
Humans use seaweeds nutritionally as food, industrially for animal feed and plant fertilizer, and ecologically to improve environmental conditions. [ 7 ] [ 6 ] [ 8 ] Seaweeds have been consumed by humans for centuries because they have excellent nutritional profiles, contain minerals, trace elements , amino acids , and vitamins , [ 7 ] and are ...
It is a mainstay of the modern chemical industry and provides the raw material for the most common type of fertilizer production, globally (for example, ammonium nitrate, a common fertilizer, is made by reacting ammonia with nitric acid).
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.
