Abstract

Fly-ash (FA) is largely alkaline in nature and contains many essential elements for plant growth along with toxic metals.  Therefore, fly-ash is potential to be applied as soil ameliorate that may improve soil properties and plant growth.  In this experiment we studied the changes in chemical properties and rice production  of acid sulphate soils amended with fly ash.  Six different amounts of FA, viz. 0 (100% soil), 5, 10, 20, 40 and 75 tones FA ha-1 were added homogenously to 6 kg of soils in pots of PVC and then chemical properties of acid sulphate soils were observed after a 3-week of incubation. Subsequent of  the observation of soil properties, rice was planted onto the pots.  Results of study showed that fly-ash application improved soil pH and exchangeable Ca.  However, the availability of nitrogen of acid sulphate soils decreased significantly with fly-ash application.  The experiment also showed that fly-ash application to soils improved rice growth (height plant, number of tillers, dried-weight root and dried-weight shoot) and rice production. Application 20 tones FA ha-1 resulted in higher rice production than the application 0, 5 and 10 tones FA ha-1, and increasing subsequent the amount of FA application did not significantly increase the rice production. Results of this study demonstrate that low-level fly-ash application resulted in the improvements of soil chemical properties and rice production.Key words: fly-ash application; soil ameliorant; heavy metals; sub-optimal low land.

Abstract

The raised-bed soil is a land management technology in South Kalimantan. Adding Ameliorant to the raised-bed soil as an effort to increase the utilization of support for the cultivation land. Chlorophyll or leaf green substances found in all green plants that carry out photosynthesis. Ameliorant applications can increase the chlorophyll content of plants to optimize plant growth. This study aims to look at the effect of giving several types of ameliorant to the content of chlorophyll (chlorophyll-a, chlorophyll-b and total chlorophyll) and the growth of corn planted on raised-bed soil. This research is an experiment in the laboratory and a greenhouse. This research was conducted using a Completely Randomized Design (CRD) Single Factor with the treatment tested was the type of ameliorant soil without treatment (control - K), soil + agricultural lime (dolomite - C), soil + palm empty fruit bunch ash (S), soil + rice husk ash (P) and soil + coal ash (B). All treatments were repeated 5 (five) replications so that there would be 25 units of the experiment. The results showed that the application of ameliorant in raised-bed soil using dolomite and oil palm empty fruit bunches ash with a dose of 5 tons ha-1 affected the content of chlorophyll-a and total chlorophyll in the growth of corn planted in raised-bed soil materials.
