Using of critical land for agricultural cultivation must be done carefully and wisely, given the status of the land itself which has vulnerability. The first step that can be done is to analyse the soil properties that are important and related to plant growth factors, especially the chemical and physical properties of soils which directly affect plant growth. The purpose of this study is to describe the characteristics of critical dry land in Indrapuri and Blang Bintang Sub-district, Aceh Besar Regency, Aceh Province. The research method was used a field survey covering the area of Indrapuri and Blang Bintang Sub-districts. The descriptive analysis was done for the field data and laboratory obtained. Soil samples that have been taken from the field before being analyzed are air dried for 1 week, after that they are ground and sieved using 2.0 sieves for soil texture analysis and using 0.5 mm sieves for analysis of soil chemical properties such as pH, C-organic, exchangeable cations (Ca-dd, Mg-dd, K-dd, and Na-dd), cations exchange capacity (CEC), base saturation (KB), total nitrogen, and P2O5. The finding of this study is there are 3 categories of critical land in Blang Bintang Sub-district, namely critical potential of 2,027 ha, critical land of 861 ha, and very critical land with an area of 1,341 ha. Land in the agricultural cultivation area in Indrapuri Sub-district has 3 (three) levels of land criticality, namely: uncritical land area of 5,280 ha, rather critical land area of 6,562 ha, and critical area of 3,135 ha. Land with varying degrees of criticality in Blang Bintang and Indrapuri Sub-districts is generally has very low to low soil fertility.
