Abstract
In Indonesia, livestock urine is considered as waste, while weed of Chromolaena odorata, which are very toxic to ruminants, is abundant in grassland area. These two materials have great potential to improve soil fertility because they can be made to organic fertilizer through fermentation. Fermentation of mixed urine, Chromolaena and water with the proportion of 25:25:50% added with small proportion of yeast tape, a liquid fertilized produced with nutrient contents of N, P2O5 and K2O was 2.3, 0.32 and 0.15%, respectively. The research results showed that the application of liquid fertilizer significantly improved (P<0.01) the growth and biomass production of Panicum maximum, Brachiaria decumbens and Pennisetum purpureum where Panicum maximum showed the best response.
