Through the use of biofertilizers, healthy plants can be grown, while enhancing the sustainability and the health of the soil. Biofertilizers can be expected to reduce the use of synthetic fertilizers and pesticides, but they are not yet able to replace their use. As of 2024, more than 340 biofertilizer products have been approved for ...
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.
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. [89] The phosphate rock used in their manufacture can contain as much as 188 mg/kg cadmium [ 90 ] (examples are deposits on Nauru [ 91 ] and the Christmas Islands [ 92 ] ).
For example, Integrated Pest Management is a multifaceted strategy that uses various organic methods of pest control whenever possible, but in conventional farming could include synthetic pesticides only as a last resort. [49] Examples of beneficial insects that are used in organic farming include ladybugs and lacewings, both of which feed on ...
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.
Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example, a 10-10-15 fertilizer has 10 percent nitrogen, 10 percent available phosphorus (P 2 O 5) and 15 percent water-soluble potassium (K 2 O). Sulfur is the fourth element that may ...
School feeding is just one facet of school health initiatives, as other programs may include de-worming, HIV/AIDS prevention and education, and life and health skills education. Overall, school feeding programs have been shown to directly increase the educational and nutritional status of recipient children, and indirectly impact the economic ...
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 .
