Abstract

Gambier plants (Uncaria gambir.Roxb) are the main plantation commodity in West Sumatra. However, cultivating gambier on steep slopes can cause changes in soil chemical properties. This research aims to examine the chemical properties of soil on gambier land based on slope class in Nagari Siguntur. This research was carried out from June to December 2022. The method used was a survey method with the Purposive Random Sampling technique. Soil samples taken were soil samples on 3 slopes and forest as a control (45%) at a depth of 0-30 cm with 3 replications. The analysis results show the soil pH value is between 3.98–4.47 with very acid criteria. Soil C-Organic content is between 0.86%-1.76% with very low to low criteria. The N-Total content is between 0.26%-0.32% with medium criteria. The P-Available content is between 2.15 ppm-13.54 ppm with very low to low criteria. CEC with a value of 14.39-17.02 cmol/kg with low to moderate criteria. And the exchangeable cations in gambier land are classified as very low criteria.

Abstract

Cold lava floods contain volcano material that is rich in micronutrient which will gradually release through weathering process. The study of micronutrient elements affected by cold lava floods was conducted in Nagari Limo Kaum, Tanah Datar Regency, from October to March 2025. This research was aimed to assess and analyze the content of micronutrients (Fe, Mn, Cu, Zn, Mo and B) in land impacted by cold lava floods in Nagari Limo Kaum, Tanah Datar Regency. The study was carried out using a survey method. Soil samples were collected using purposive sampling from lava deposit (Locations 2, 3, and 4), areas affected by floodwater flow without deposition (Location 5), and unaffected areas (Location 1) as a comparison. Soil samples were collected from 0-20 cm soil depth at each location with 3 replicates. The analyzed parameters included soil pH, cation exchange capacity (CEC), exchangeable aluminum, and micronutrients (Fe, Mn, Cu, Zn, Mo and B). The results showed that increased the micronutrient content and exchangeable aluminium, increased while Zn and B content had low to very high criteria. The chemical properties especially pH and CEC of the soil  at L1 and L5, were lower that those at impacted soils.
