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.
Phosphate is often adsorbed onto the surface of different type of minerals, for example iron containing minerals. Recent data suggest that bacteria growing under phosphorus starvation release iron-chelating molecules.
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.
For example, mono-ammonium phosphate fertilizer may have a cadmium content of as low as 0.14 mg/kg or as high as 50.9 mg/kg. [90] The phosphate rock used in their manufacture can contain as much as 188 mg/kg cadmium [ 91 ] (examples are deposits on Nauru [ 92 ] and the Christmas Islands [ 93 ] ).
A laboratory specimen is sometimes a biological specimen of a medical patient's tissue, fluids, or other samples used for laboratory analysis to assist in differential diagnosis or staging of a disease process. These specimens are often the most reliable method of diagnosis, depending on the ailment.
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 .
Other examples are natural enzyme-digested proteins. Decomposing crop residue (green manure) from prior years is another source of fertility. Compost provides little in the means of nutrients to plants, but it does provide soil stability through increasing organic matter.
Biotechnology is the research and development in the laboratory using bioinformatics for exploration, extraction, exploitation, and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned (reproduced by biosynthesis, for example), forecasted, formulated ...
