Abstract

This study aims to determine the effect of swallow droppings and its best treatment on pH, CEC, organic-C, mineral-N, and available-P in Ultisols. The research method used was a one-factor Completely Randomized Design (CRD) with an incubation period of two weeks, with five treatments of 0, 2.5, 3.0, and 3.5 t ha-1 swallow droppings. Each treatment repeated four times to make 20 experimental units. Parameters observed were soil pH (H2O), CEC, organic-C, mineral-N, and available-P. The results showed that the application of swallow droppings affected pH, CEC, organic-C, mineral-N, and available-P in Ultisols. Swallow droppings of 3.5 t ha-1 significantly affected mineral-N (N-NH4+ and N-NO3-) and other parameters such as CEC, available-P, pH, and organic-C.

Abstract

Swamps in Indonesia are widely spread over four major islands, namely in Sumatra, Kalimantan, Papua, and Sulawesi Papua. The problem with acid-sulfate soils is when the pyrite layer is oxidized. This study used a two-factorial with completly randomized design (CRD). The first factor was flooding fluctuation an the second factor was lime with straw compost. The soil parameters tested were pH and soluble Fe. Observations in the second week of the treatment of fluctuations in puddles that were drained, then flooded and added with a mixture of 3 t ha-1 lime, and 2.5 t ha-1 of straw compos resulted in the highest pH of 6.21. The best soil pH was given lime at 3 t ha-1, both flooded and drained. Observations in the fourth week produced the highest pH, namely 4.80. The pH value of the slightly acidic soil was due to an oxidation-reduction process. The 2nd week of observation had the highest soluble Fe value of 221 mg kg1, which was due to the analysis of soluble Fe using a pH of 4.8 so that Fe2+ increased in dissolved Fe. The fourth week of observation had the lowest soluble Fe value of 56.34 mg kg-1. This was due to flooding and the application of a mixture of lime and rice straw compost. The results of the study show that the interaction of fluctuations in water, lime, and rice straw compost that can affect soil pH and the solubility of soil soluble iron (Fe2+).
