Fish waste may help agriculture Published:  10 June, 2005

A STUDY into whether fish waste could help wastewater become usable in agriculture is being undertaken by a fish farmer in Wyoming, US, Denverpost.com reported.

Earlier studies carried out by a local fish farmer have been successful and indicated that when plants receive wastewater containing fish manure, it could help promote growth, increase uptake of sodium into plant tissue and even change the structure of the soil, improving water infiltration.

One of the leading concerns with saltier water is that it can harm soil and growing conditions, essentially gumming up or sealing off topsoil. But if water not used by the plants can percolate below the root zone and move the sodium farther down — as the tests using fish manures indicated it could be used in agriculture. If the project works it could lead to higher-value irrigated crops for landowners and provide another water disposal option for energy companies.
