Recycled compost reduces phosphorus in soil

International scientists have found that vegetables grown using inorganic fertilisers, poultry manure, and based in metropolitan areas, show high levels of phosphorus.

The research was carried out as part of a project to look at the benefits of using green recycled compost in gardens for growing vegetables. Although it was found that over time, additional sources of nitrogen might be required, overall the compost reduced the need for inorganic fertilisers and led to healthier soil.

It also cuts down drastically on the level of phosphorus in the vegetables produced, increasing their nutritional value, and leading to healthier and more stable soils.
