Kualitas Pupuk Organik Cair Dari Urine Sapi Pada Beberapa Waktu Simpan

Abstract

Quality of Liquid Organic Fertilizer from Cattle Urine on Different Time Store . The research aimed to investigate save time of liquid organic fertilizer from cattle urine to value of N, P, and K available. The research used Randomized Completed Block Design (RCBD) with six treatments and three replications. The treatments were liquid organic fertilizer from cattle urine stored for 0 week (T 0 ); liquid organic fertilizer from cattle urine stored for 2 weeks (T 1 ); organic fertilizer from cattle urine stored for 4 weeks (T 2 ); organic fertilizer from cattle urine stored for 6 weeks (T 3 ); organic fertilizer from cattle urine stored for 8 weeks (T 4 ); and organic fertilizer from cattle urine stored for 10 weeks (T 5 ). Statistical analysis used was the Analysis of Variance and Honestly Significant (HSD) at 5% significant level. The result of research treatment of liquid organic fertilizer from cattle urine stored for 0 weeks (To) contains an average of available N as 5:27, the content was reduced to 3.4% at 10 weeks old store .  A vailable N reduced by 1.87% is equivalent to 35.48%, shows considerable loss of available N. The average levels of available P in a liquid organic fertilizer from cattle urine that has been stored for 0 weeks (To) is 64 ppm. The average levels of available P in a liquid organic fertilizer from cattle urine that has been stored for 10 weeks is 60 ppm, has been reduced as much as 4 ppm equivalent to 6.25% compared to T 0 . The average levels of available K are liquid organic fertilizer from cattle urine that has been stored from 0 to 10 weeks tended to decrease in the least amount. Liquid organic fertilizer from cattle urine which ha s been stored for 0 weeks ( To) having an average grade of  available K at 16.82 ppm , the content to be 16.57 ppm at 10 weeks old ( T5). A vailable K has been reduced as much as 0.25 ppm equivalent to 1.49% which showed no significant decline. Key words: liquid organic fertilizer from cattle urine, store time, N available, P available, and K available
