Studies have shown that human hair, a readily available waste generated from barbershops and hair salons, combined with additional compost, is an additional nutrient source for crops.
Although human hair has become commercially available to crop producers in the past couple years, it has not been proven to be an exclusive source of nutrients in greenhouse container production.
China Uses Harmful Methane Gas for Producing Electricity
China has started the world's largest cow-dung methane power plant in the Inner Mongolia region, thus using the greenhouse gas methane for generating electricity on a massive scale.
China has started the world's largest cow-dung methane power plant in the Inner Mongolia region, thus using the greenhouse gas methane for generating electricity on a massive scale.
The study compared the productivity of four crops: lettuce, wormwood, yellow poppy, and feverfew, grown in commercial growth medium using untreated control, noncomposted hair cubes at differing weights, a controlled-release fertilizer and a water-soluble fertilizer.
Results showed that, with the addition of hair waste cubes, yields increased relative to the untreated control, but were lower than yields in the inorganic treatments, suggesting that hair waste should not be used as a single source for fast-growing plants such as lettuce.
Climate Change Will Hit India's Farming, Water Supply, Health
Climate change will affect India's poor the worst, in areas like agriculture, water supply and health, former environment minister Suresh Prabhu said here Monday.

Because of possible health concerns, further research is necessary to determine whether human hair waste is a viable option as fertilizer for edible crops.

Indian Researcher Finds Human Urine Grows Better Fish Food
A researcher from the University of Kalyani, India, has found that plankton used as food on fish farms, live longer and produce more offspring if reared in diluted urine.
