Abstract

Paddy fields and mixed farming apply intensive agricultural cultivation, and sustainable land use causes changes in land quality, one of which affects soil chemical properties. This study aimed to compare soil chemical properties based on differences in the use of paddy fields and mixed farming in Sungai Kakap District, Kubu Raya Regency, West Kalimantan. Research in the field in Pal IX Village, Sungai Kakap Sub-district, Kubu Raya Regency, for sampling soil samples at 0-20 cm depth. Soil analysis was conducted at the Chemistry and Soil Fertility Laboratory, Faculty of Agriculture, Tanjungpura University. The results showed that the two fields, paddy fields, and mixed farming, had almost the same chemical properties in paddy fields pH, organic C,  available P, cation exchange capacity (CEC), exchangeable Ca and exchangeable Mg.

Abstract

This research aims to compare the methods of bulk density measurements in peat soils. The methods are ring sample, peat auger, and syringe. The research was conducted in peat soils in Pontianak City. The research was carried out from June to December 2023. Peat samples were the surface peat (0-10 cm). The samples were collected from five plots, and five replications. On average, the value of bulk density measured by the ring sample was 0.27 g cm-3, which is significantly different from bulk density values measured by the peat auger and syringe: 0.11 g cm-3 and 0.09 g cm-3, respectively. Bulk densities of peat auger and syringe are statistically indifferent. Soil compaction during sampling causes the ring sample's high bulk density value. Accordingly, carbon stock calculation based on ring sample bulk density is significantly higher than carbon stocks calculated by bulk densities of auger and syringe. The bulk density measurement with a peat auger took longer because a water displacement approach must measure the sample volume. Collecting bulk-density samples with a syringe is the easiest and fastest. The volume of the syringe sample is only 10 cm3, and the sample can be taken until the mineral substratum. The number of sample collected by syringe can be significantly increased at 5 cm sampling interval, or equals to 10 sub-samples per 50 cm peat core. Pearson linear correlations of these three methods are sufficiently strong.
