Improved Composting Through Fermented Activators

Abstract:

<p style="text-align: justify;">Composts are important components in improving or restoring soil fertility. However, it takes long time for it to prepare and buying starter cultures of beneficial microorganisms to speed-up composting can be expensive. Thus, a study was conducted to quantify microorganisms from the different fermented activators and EM using PCA, determine the duration of compost maturity, percent recovery of compost, and nutrient content and pH of compost as affected by different fermented activators and EM. Significant lower temperature were registered on the compost (30% Browns + 30% Greens + 40% Banana Bract) applied with commercial effective microorganism (EM) from five to eight weeks of composting than those applied with fermented activators and tap water. Such is a sign of earlier maturity. Meanwhile, application of Fermented Swamp Cabbage Juice alone improved the percent recovery of compost by 0.36 times (46.70%) compared to those applied with tap water only (34.33%). Furthermore, application of commercial EM and Fermented Swamp Cabbage Juice alone also improved the nutrient contents (N, P2O5 and K2O) of the compost after four and eight weeks of composting.</p>
