Productivity and Chemical Parameters in the Bottom Soil of 1 and 3 years operated pond of Black Tiger Prawn Penaeus monodon Fab. Culture
Abstract
This study was carried out to observe the productivity and bottom soil chemical aspects of 1 year and 3 years operated pond of black tiger prawn Penaeus monodon Fab. culture. The results of study depicted that pond operated for 3 years contained higher (P<0.05) organic carbon (10.36%) and nitrogen (0.22%), but lower Fe compared with 1-year-pond operated. Sulfur content tends to increase with increase in age of pond. Productivity of 3-year-pond was lower (P<0.05) than that of 1-year-pond operated.

ABSTRAK
Tujuan dari penelitian ini adalah untuk mengetahui produktivitas dan parameter-parameter kimia tanah dasar tambak budidaya udang (Penaeus monodon Fab.) yang telah beroperasi selama 1 dan 3 tahun. Hasil penelitian menunjukkan bahwa tambak umur 3 tahun mengandung karbon organik (10,36%) dan nitrogen (0,22%) lebih tinggi, sedangkan konsentrasi Fe cenderung lebih kecil dibandingkan tambak umur 1 tahun. Konsentrasi sulfur cenderung meningkat dengan bertambahnya umur tambak (P<0,05). Produktivitas tambak umur 3 tahun lebih rendah (P<0,05) dibandingkan tambak umur 1 tahun.
