Abstract

Dewi et al, 2019. The Effect of Addition of Liquid Fertilizer on Soil Fertility and Water Quality in Pond at Tidal Lowland. JSLO 8(1):The soil of tidal lowland contains a lot of sulfidic material, low soil pH (> 3.50), high toxic substances and low soil fertility. This study aimed to compare the effect of adding liquid fertilizer to soil ponds is made of afkir fruit on tidal swamp land. The research used three treatments without replication. The treatments were pond without liquid fertilizer/control (P0), addition of liquid fertilizer concentration 0.131 L.m-3 (P1) and 0.261 L.m-3 (P2). The parameter were water quality, soil fertility, abundance and composition of plankton, and plankton that were potensial as natural feed of fish. The data obtained processed using descriptive analysis. The result of this research indicated that the addition of liquid fertilizer in KTM Telang Banyuasin gave positive changes to water quality and soil fertility parameters such as pH, secchi depth transparency, ammonia, orthophosphate, iron, N-total, P-available, K-dd, C-organic and pyrite, and has a negative effect on dissolved oxygen.. The treatment P2 resulted in highest plankton abundance value of phytoplankton (7974 ind.L-1) and zooplankton (192 ind.L-1), the fertility of pond was on moderate level (mesotrophic), 100% of phytoplankton natural food potency and 71.4% of zooplankton natural food potency.
