Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water.
The thermal hydrolysis system at the Blue Plains treatment plant in Washington, D.C. is the largest in the world as of 2016. Phosphorus recovery from sewage sludge or from sludge dewatering streams is receiving increased attention particularly in Sweden, Germany and Canada, as phosphorus is a limited resource (a concept also known as " peak ...
It affects potatoes, tomatoes, and beans, causing deformed plants, and poor or non-existent yields. Problems with manure contaminated with aminopyralid residue surfaced in the UK in June and July 2008, and, at the end of July 2008, Dow AgroSciences implemented an immediate suspension of UK sales and use of herbicides containing aminopyralid.

However, the use of herbicides can cause phytotoxic effects on non-targeted plants through wind-blown spray drift or from the use of herbicide-contaminated material (such as straw or manure) being applied to the soil. [5] Herbicides can also cause phytotoxicity in crops if applied incorrectly, in the wrong stage of crop growth, or in excess. [1]
After this, it can possibly still be burned for energy, or even converted into biogas or compost through fermentation. [ 27 ] In an effort to reduce the negative impact of agricultural waste on earth, some companies have focused on developing new technologies that allow agricultural waste to be put to meaningful use and returning to traditional ...
In Thailand this system has been used by 470 farmer groups. (May, 2008). [2] The process required 30 days to finish without turning, with 10 metric tons of compost (10 piles) obtained each time. A 15-inch squirrel-cage blower was used to force the air through 10 static piles of compost, one at a time, for 15 minute periods twice a day.
Herbicide safeners are organic compounds used to enhance the effectiveness of herbicides, to make them "safer".They minimize the effect of the herbicide on crop plants, thereby improving selectivity between crop plants vs. weed species being targeted by the herbicide.
An organic garden on a school campus. The following outline is provided as an overview of and topical guide to organic gardening and farming: . Organic farming – alternative agricultural system that relies on fertilizers of organic origin such as compost, manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting.
