Overview

Land evaluation study maps crop suitability in tropical farmland, indicating distinct terrain and nutrient limits for regional staple crops.

Key Points

  • Determine land suitability classifications for paddy, corn, and soybean cultivation using digital agroecological zoning and local crop requirements.
  • Gathered climatic, soil, and plant growth parameters through field surveys and literature reviews.
  • Overlaid spatial and environmental criteria using the Automated Land Evaluation System (ALES) to delineate agroecological zones.
  • Zone IV (slope <8%) dominated the landscape at 66.69%, while Zone III (8–15% slope), Zone II (15–30% slope), and steep terrain (30–40% slope) accounted for 1.77%, 3.38%, and 4.79%, respectively.
  • Highly suitable (S1) land covered 37,062 Ha (33.09%) for rice and 14,698 Ha (13.12%) for corn.
  • Moderately suitable (S2) land for soybean comprised 10.99% limited by nutrient retention (S2nr) and 18.33% limited by root media and nutrient retention (S2rc, nr).
