Minimizing the impact of climate change through the determination of land and plant technology needs based on the agroecological zone on food crops in Boyolali District of Central Java, Indonesia

Abstract

The agroecological zone (AEZ) is a land potential information system for land use planning and commodity development. AEZ contains information on landforms, elevation, topography, soil characteristics, temperature, etc. which is useful for determining the suitability of land and commodities. This study aims to determine the technology requirement based on the limiting factors found in each land unit. The methods of determination of land suitability and technology requirement were carried out using the FAO standard land evaluation program, by matching land characteristics with plant growth needs. Through the application of recommendation technology that suitable for land capability, the cultivation system becomes more adaptive to the environment, so that the possible negative impact of climate change can be minimized. The limiting factors found as constraints to the development of food crops in the Boyolali District include (a) temperature conditions, (b) rooting conditions, (c) nutrient retentions, (d) erosion hazard, (e) land preparation, and (f) flooding hazard. Based on existing limiting factors, land management should be focused on (a) using adaptive varieties to local temperatures; (b) providing organic fertilizer to improve soil drainage, organic C and CEC soil; (c) lime and soil ameliorant application to increase base saturation, deep and reverse soil treatment to increase CEC; (d) conservation-oriented planting system and (e) eradication of rocks with minimum tillage.
