Abstract

Organic liquid fertilizer is the source of nutrients.  This fertilizer can be used to improve the water quality.  It is enviromentally friendly  and relatively cheap.  Application of the fertilizer has been done on aquaculture.  At the tidal lowland areas, application of this fertilizer is mostly as soil improvement agent.  It is limited to be used as water quality improvement agent.  Tidal lowland has an acid soil with a low fertility level characters. The objectives of the study are to know the effect of liquid organic fertilizer to the water quality (temperature, pH, dissolved oxigen, ammonia) and to the amount of plankton in the ponds. This research was done at the reclaimed tidal lowland in Banyuasin District of South Sumatera, Indonesia.  The organic liquid fertilizer was made by fermentation of  both animals manures and vegetable waste with the percentage of N : P2O5 : K2O were 0.120 : 0.023 : 0.750.  Water quality data was taken three times in every three days (plankton) from the ponds that was added by liquid fertilizer with dose of 4.35 L /pond (P1) and 8.7 L/pond (P2).  All the water quality data were analyzed qualitatively.  The results show that on treated  ponds pH dropped slightly since the beginning with pH 6.0 and remain 6.4 - 6.8 in the last day.   The value of  Ammonia ranges 0.06-0.15 mg.L-1 and Dissolve oxigen range 1.9-2.5 mg.L-1‑.    Phytoplankton and zooplankton amount increased and reached the peak on day 12 (12033 ind.L-1 and 364 ind.L-1 respectively), and finally turned down slowly.  Therefore, liquid fertilizer addition should be given to the ponds more than once during fish rearing period.  It is  in order to increase the amount of  plankton and to manage the water quality in the reclaimed tidal lowlands ponds

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.
