The organic system showed significant lower levels of organic matter and phosphorus when compared to the two conventional systems. The results indicate that the conventional systems release large amount of nutrients into the environment and the organic system is a sink of nutrients from the Guaraira Lagoon ecosystem. 2007 Conference paper, poster, etc. NonPeerReviewed application/pdf http://orgprints.org/9911/1/9911_Schober_Vortrag.pdf Schober Lima, Juliana and Focken, Ulfert (2007) Analysis of Soil Nutrients and Organic Matter in organic and conventional Marine Shrimp ponds at Guaraíra Lagoon, Rio Grande do Norte State, Brazil.
