Exploring the Triad: pH, Nitrogen, and Phosphorus Characteristics of Peat Soils in Humbang Hasundutan Regency

Abstract

Peat soil is a soil with low nutrient content, due to the weathering process of organic materials in peat land not taking place well. The characteristics can be observed in its physical, chemical, and biological properties. This study aimed to determine the chemical characteristics of peat soil in the Humbang Hasundutan Regency. The chemical characteristics of peat soils include the degree of acidity (pH), nitrogen (N), and phosphorus (P). Peat soil samples were obtained from Lintong Ni Huta District, Dolok Sanggul District, and Pollung District. The results of the pH parameter testing in the Lintong Ni Huta District, Dolok Sanggul 1 District, Dolok Sanggul 2 District, and Pollung District were 4.56, 4.42, 4.61, and 4.68, respectively. Testing of N parameters on peat soil showed that the peat soil originating from Lintong Ni Huta District was 0.7387%, Dolok Sanggul 1 District was 0.6738%, Dolok Sanggul 2 District was 0.4657%, and Pollung District was 0.8352%. Testing of the P parameters on peat soil showed that the peat soil originating from Lintong Ni Huta District, Dolok Sanggul 1 District, Dolok Sanggul 2 District, and Pollung District were 0.2951 %, 0.3995 %, 1.4903 %, and 1.252 %, respectively.
