2. Seaweed fertiliser - Wikipedia

   en.wikipedia.org/wiki/Seaweed_fertiliser

   [4] [5] Seaweed fertilizer application to soils can also alter the structure and function of microbial communities. Seaweed aquaculture has the potential to yield ecosystem services by providing a source of nutrition to human communities and a mechanism for improving water quality in natural systems and aquaculture operations.

3. Fish emulsion - Wikipedia

   en.wikipedia.org/wiki/Fish_emulsion

   Since fish emulsion is naturally derived, it is considered an organic fertilizer appropriate for use in organic horticulture. In addition to having a typical N-P-K analysis of 5-2-2, fish emulsion adds micronutrients. [2] Fish emulsion, applied as a liquid fertilizer, is also used when growing roses to enhance the bloom color of the flowers. [3]

4. Aquaculture - Wikipedia

   en.wikipedia.org/wiki/Aquaculture

   In 1995, salmon had a FIFO ratio of 7.5 (meaning 7.5 kilograms of wild fish feed were required to produce one kilogram of salmon); by 2006 the ratio had fallen to 4.9. [103] Additionally, a growing share of fish oil and fishmeal come from residues (byproducts of fish processing), rather than dedicated whole fish. [ 104 ]

5. Aquaponics - Wikipedia

   en.wikipedia.org/wiki/Aquaponics

   Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.

6. Biofertilizer - Wikipedia

   en.wikipedia.org/wiki/Biofertilizer

   Anabaena, in association with the water fern Azolla, can contribute nitrogen up to 60 kg/ha/season and can also enrich soils with organic matter. [ 3 ] [ 4 ] Seaweeds are rich in various types of mineral elements (potassium, phosphorus, trace elements, etc.), hence they are extensively used as a form of manure replacement by people of coastal ...

7. Soil fertility - Wikipedia

   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 ...
