Soil surface charge and cation exchange are important parameters of soil fertility in tropical soils. This study was conducted to investigate characteristics of surface charges and cation exchanges on four soil orders of the dryland in Aceh Besar district. The soil order includes Entisols Jantho (05o16’58.41” N; 95o37’51.82” E), Andisols Saree (05o27'15.6" N; 95o44'09,1" E), Inceptisols Cucum (05º18’18,37” N; 95º32’48,04” E), dan Oxisols Lembah Seulawah (05o27’19,4” N; 95o46’19,2” E). The charge characteristics of surface charge are evaluated from the parameter of DpH (pHH2O-pHKCl), variable charge (Vc), permanent charge (Pc), and point of zero charges (PZC). In contrast, cation exchange properties are evaluated from several soil chemical properties, such as soil organic matter (SOM), base saturation (BS), cation exchange capacity (CEC), and effective CEC (ECEC). The results show that the four pedons of soil in the hilly dryland of Aceh Besar include a variable charge because it has a PZC, which is characterized by a negative surface charge with a PZC of pHH2O and has CEC dependent soil pH. PZC value varies from 3.21 – 5.26 and sequentially PZC Andisols Oxisols Entisols Inceptisols. The total CEC value differs considerably from ECEC and the sum of cations. CEC total of the soils varies from 12.8 – 34.4 cmol kg-1, whereas the ECEC values vary from 2.72 – 8.66 cmol kg-1. The highest variable charge percentage is found in Andisols Saree. In contrast, the highest permanent charge is found in Inceptisols Cucum and is positively correlated with pHH20, PZC, CEC, and sums of cations or ECEC. Improving soil quality in hilly dryland soils in Aceh Besar District can be done by decreasing the PZC status of soils with organic amendments and fertilizers or increasing the pH by using liming.

Penelitian ini bertujuan untuk mengkaji tingkat kemasaman tanah dan pertukaran kation pada dua ordo tanah di lahan kering Kabupaten Aceh Besar yaitu pada Mollisols Krueng Raya dan Ultisols Jantho. Kedua ordo tanah tersebut terbentuk dari bahan induk yang berbeda. Mollisols Krueng Raya terbentuk dari bahan induk batuan sedimen gampingan, sedangkan Ultisols Jantho dari bahan induk batuan sedimen liat tua. Penelitian dilakukan dengan menggunakan metode survai deskriptif yaitu melalui pengamatan di lapangan dan analisis di laboratorium. Identifkasi profil dan ordo tanah dilakukan dengan menggunakan sistem klasifikasi tanah USDA (Soil Survey Staff, 2014). Pengambilan sampel tanah dilakukan pada setiap lapisan horizon dari setiap profil pewakil ordo tanah yang diamati di lapangan. Sampel-sampel tanah tersebut selanjutnya dibawa ke laboratorium untuk dianalisis pH (H2O), kapasitas tukar kation (KTK) dan kation dapat ditukar (Ca, Mg, K, dan Na) ditetapkan dengan metode 1N NH4COOCH3 pH7, sedangkan Al- dan H-dapat ditukar diekstrak dengan 1M KCl. Hasil penelitian menunjukkan bahwa kedua ordo tanah yang diteliti memiliki tingkat kemasaman dan pertukaran kation yang berbeda. Mollisols Krueng Raya mempunyai pH agak masam hingga agak alkalis (6,48-8,2) dan KTK tinggi, sedangkan Ultisols Jantho bereaksi masam (pH 6,50) dan mempunyai KTK dan kejenuhan basa yang rendah.Soil Acidity and Cation Exchange Properties in Mollisols and Ultisols in Dryland of Aceh Besar DistrictAbstract. Soil acidity and cation exchange is an important indicator of soil fertility especially on suboptimal drylands. Soil acidity and cation exchange closely related to the parent materials of soil. This study aims to assess soil acidity level and cation exchange in two soil orders of dryland in Aceh Besar District namely Mollisols Krueng Raya and Ultisols Jantho. The two soil orders are formed from different parent materials. The Mollisols of Krueng Raya are formed from limestone sedimentary rock, while Ultisols Jantho are formed from the parent material of the old clay sedimentary rock. The research is conducted using a descriptive survey method that is through field observations and analysis in the laboratory. Identification of soil profile and soil orders were conducted using USDA's soil classification system (Soil Survey Staff, 2014). Soil sampling is taken from each layer of the horizon of the soil orders that are observed in the field. These soil samples were subsequently brought to the laboratory for analysis of pH (H2O), cation exchange capacity (CEC) and exchangeable cations (Ca, Mg, K, and Na) are extracted by 1N NH4COOCH3 pH7, while exchangeable Al and H were extracted with 1M KCl. The results of analysis showed that both the soils orders being researched had a different level of acidity and exchange of cations. Mollisols of Krueng Raya has a moderately alkaline pH that is slighty alkalis (6.48-8.2) and high CEC, while the Ultisols Jantho has an acid pH (pH 6.50) and has low CEC and low base saturation.

Abstrak. Lahan kering di Indonesia terutama di Aceh memiliki potensi yang sangat tinggi, namun umumnya lahan kering memiliki status kesuburan tanah rendah. Penelitian ini bertujuan untuk mengetahui status dan kendala kesuburan tanah pada lahan kering di Kecamatan Blang Bintang Kabupaten Aceh Besar Provinsi Aceh. Penelitian ini dilakukan dengan menggunakan metode deskriptif yang difokuskan pada dua tipe penggunaan lahan kering yaitu penggunaan lahan kebun campuran dan tegalan/tanaman semusim. Parameter yang diukur dalam penelitian ini meliputi: pH, C-organik, P2O5, K2O, P tersedia, K-dd, Ca-dd, Mg-dd, Na-dd, Al-dd, KTK dan KB. Berdasarkan hasil penelitian, penggunaan lahan kebun campuran termasuk kedalam kriteria status kesuburan tanah rendah sedangkan tegalan tergolong ke dalam kriteria dengan status kesuburan tanah sedang. Faktor penghambat yang menjadi kendala kesuburan tanah pada kering di Kecamatan Blang Bintang yaitu rendahnya kandungan C-organik dan kejenuhan basa (KB) tanah. Selain itu, nilai pH tanah yang tergolong masam hingga agak masam juga menjadi salah satu kendala kesuburan tanah pada lahan kering Kecamatan Blang Bintang. Status and Constraints of Soil Fertility in Dry land and mixed garden in Blang Bintang Aceh BesarAbstract. Dry land in Indonesia, especially in Aceh, has very high potential, but generally dry land has low soil fertility status. This study aims to determine the status and constraints of soil fertility on dry land in Blang Bintang District, Aceh Besar District, Aceh Province. This research was conducted using a descriptive method that focused on two types of dry land use, namely mixed garden land use and moor/seasonal crops. The parameters measured in this study included: pH, C-organic, P2O5, K2O, available P, K-dd, Ca-dd, Mg-dd, Na-dd, Al-dd, CEC and KB. Based on the results of the study, the use of mixed garden land was included in the criteria for low soil fertility status, while moor was included in the criteria with moderate soil fertility status. Inhibiting factors that become an obstacle to soil fertility in dry areas in Blang Bintang District are the low content of C-organic and alkaline saturation (KB) of the soil. In addition, the pH value of the soil which is classified as acidic to slightly acidic is also an obstacle to soil fertility in the dry land of Blang Bintang District.

Observations were conducted at 10 sample points, namely five samples in SPL-1, four samples in SPL-2 and one sample representing SPL-3. Soil samples consist of two kinds, namely undisturb soil samples taken using a ring sample and disturbed soil samples taken using a soil auger. All samples were taken at a depth of 0-20 cm. The results showed that from the physical aspect of the soil, the area had a loam to clay texture (medium to fine), medium bulk density (1.24-1.27 g cm-3), and some areas had slow permeability ( 2 cm h-1). From the aspect of soil chemistry, this patchouli planting area has slightly acidic to neutral soil pH (pH 5.81-6.66), very low organic C content (0.68-0.72%), very low total N (0 .08-0.17%), and very low available P (0.47-1.15 mg kg-1), but the cation exchange capacity (CEC) of the soils was high ( 25 cmol kg-1). Physical and chemical constraints of the soil in the patchouli planting area in Teungoh Geunteut Village are recommended to provide amendments, especially organic amendments such as compost, green manure, animal manures, biochar and the addition of complete and balanced fertilizers is needed.
