Study on the potential of silica-available based on types of soil on the productivity of paddy field in West Java Province, Indonesia

The Si-available (Siap) content in the soil of paddy fields is decreasing, so it will affect decreasing productivity fields. Soil type maps can be used to estimate potential Siap purpose this study was assess field West Java Province based on each region using types and data. This research conducted Province. carried out from February 2021 March 2021. method descriptive method. secondary data analysis that no test out. validation literature previous researchers. parameters measured were: distribution fields, percentage field, average soil, levels, for map Secondary obtained were then analyzed spatial analysis. results show 77% have medium potential, 17% low 7% high. correlation plants has a strong (r = 0.99) soil. plants. Si application recommended southern
