| description | This dissertation aims to overcome the low physical fertility of the pond
bottom soil, which is made up of the sandy Inceptisols. Improving the soil physical
quality can be achieved by modifying the soil texture from sandy loam to clay. This
is achieved by physically mixing the Inceptisols with soils that have higher clay
content, such as Ultisols and Vertisols. The mixing is proposedly meant marling.
This research was carried out from August 2006 to September 2008 in a rice field at
Sewon Village, Argomulyo, Cangkringan, Sleman, Yogyakarta. The objectives of
this research are (1) To study the effect of mixing Ultisols and Vertisols on the
productivity of the Inceptisols pond bottom soil, (2) To study the effect of basal
fertilizer application on the pond bottom soil fertility and growth of benthic algae,
plankton, and red tilapia larvae, (3) To find an optimal fertilization frequency by
quail manure droppings on the growth of benthic algae and plankton as natural feed
to red tilapia larvae, (4) To study the effect of Inceptisols Parent layer (P)
compaction and the addition of quail manure fertilizer on nutrient availability during
the first planting period (PP-1) and the residual effect on pond productivity in the
second planting period (PP-2), and (5) To increase the red tilapia seed production.
The results showed that the Inceptisols-Ultisols and Inceptisols-Vertisols
mixture with clay content between 41-51% gave significant effect (P<0.05) on the
chemical characteristics of the pond bottom soil, such as EC, pH, organic matter
content, CEC, base saturation, Fe and K availability, C/N ratio, Ca2+, Mg2+ , K+ and
Na+. It also provided a favourable pond water quality, such as water temperature,
EC, and pH, O2 dissolved content, organic matter content, CO2 dissolved content, P,
SiO2, total of alkalinity and hardness, content of dissolved and available Fe,
ammonia (NH3), BOD, COD, total of water organic carbon, concentration of Ca,
Mg, HCO3
- (bicarbonat) and CO3
2- (carbonate), concentration of nitrate and
ammonium, and concentration of soluble reactive phosphate in pond water. Clay
content > 40% resulted in a high contribution to the increase of pond bottom soil and
water quality.
The Inceptisols was dominated by plagioclase minerals (±92%) and
halloysite (±8%). Halloysite content in the soil mixture (I-U) ranged from 28 to 50%
and the montmorillonite content in the soil mixture I-G ranged from 28 to 57%. The
high content of montmorillonite in the I-G mixture was due to the mixture with
Vertisols. Therefore, pond bottom containing montmorillonite can improve the pond
fertility and can be maintained until PP-2.
Chlorophyll production, benthic algae and plankton abundances were also
increased, which then stimulated the growth of red tilapia larvae. The total biomass,
mean of length and weight at the best dose (30%:70%) for I-U and I-G without basal
fertilizer were 68g and 99g |
