Wastewater, sludge and food crops
Article Abstract:
A sewage sludge survey, conducted under the patronage of the National Research Council, affirms the safe and effective use of properly treated wastewater effluents in food crop production. The use of reclaimed water does not pose a risk, as evident from the near absence of documented reports on their disease-inducing capabilities. However, the applicability of sludge to cropland will have to wait till the municipal authorities are able to provide reliable waste treatment programs acceptable to the community. The 14-member survey team comprised of experts from diverse fields including crop science.

Revegetating a high elevation gold mine
Article Abstract:
A study conducted at Montana State University revealed that careful use of sewage sludge and waste compost increases the fertility of the soil and the plant density, and leads to greater production of crops and plants in mined lands. Analyses of EKO and Bozeman composts revealed that the EKO compost comprises of sludge waste, yard debris and wastes of wood, whereas Bozeman compost was made of grass, clippings, leaves straw, hay manure and wood chips. The application of both types of composts yielded good results, increasing plant growth when the composts were incorporated into the soil.

Sludge compost boosts yields of California crops
Article Abstract:
A research conducted in San Diego shows that sewage sludge compost increased the growth of crop and improved the properties of the soil. Compost of waste water treatment plant was applied to test crops such as onions, lettuce, snapdragons and turf. The compost of sewage applied to crops reduced the pH and increased plant nutrients. The sludge compost had positive effect on onion, lettuce and snapdragon plants, as the compost conditions the soil like an effective fertilizer. However, it increased the soluble salts which get accumulated in the soil.
