Fertilizer from ... hair

Hair, which is what goes off at ladies' beauty and hair cutting shops, can become a useful source of nutrition for the soil if combined with other fertilizers.

That is the result of research by Mississippi State University scientists recently published in HortTechnology.

In agriculture, synthetic fertilizers from waste, animal manure, urban solid waste, sewage sludge . serve as a source of nutrient supply for the soil.

Although hair has begun to be used in this area for years, there has not been any specific scientific study to prove the effect of hair on plants.

The researchers compared the yield of lettuce, wormwood and yellow poppy plants, and were fertilized with "manure" of hair but in two different regimes.

In the first group, these vegetables were fertilized with '' stool '' raw, untreated and second hair, '' hair '' fertilizer combined with some other chemical fertilizers at doses. specific quantity. As a result, crop yields in both groups increased, but the second group grew stronger than the first.

Experts say that after decomposing and turning into minerals, hair can provide enough nutrients for plant growth. However, scientists warn that more research is needed to prove the effect of hair on soil and crops.
