Quantity of Plant Nutrients in Solution from Different Fermented Organic Materials

Abstract

The quantity plant nutrient contents in solution fermented from different organic materials was studied during March to August 2006 at Office of Extension and Continuing Education, Prince of Songkla University. This research was focused on 4 sources of micro-organisms i.e. Kyusei Foundation, Land Development Department (LDD), nature and natural micro-organisms from coconut and papaya syrup culture and 5 sources of organic materials (fruits, kitchen leavings, marine animals, fish heads and weeds). It was found that LDD micro-organism gave the highest total of primary nutrients as 2.193 percent and secondary nutrients contents as 0.320 percent. In addition, this micro-organism source also gave the highest in micronutrient contents and the lowest cost production. Comparing with 5 sources of organic materials it was found that solution fermented from fish heads gave the highest total of primary nutrients contents (i.e. 1.878 percents). Solution from kitchen leavings gave the highest total of secondary nutrients contents (i.e. 0.460 percents). This materials source also gave the highest iron and zinc contents as 64.09 and 3.92 ppm respectively. The maximum manganese content was found in solution fermented from fruits as 9.78 ppm whereas the solution obtained form marine animals gave the highest copper contents as 0.61 ppm. The aforementioned results could be summarized that, the micro-organisms form the LDD sources and marine animals are appropriate micro-organisms sources and organic materials for plant nutrient solution production.
