<div style="text-align: justify;">This study aims to find out the soil morphology diversity at the southern flank of Mt.Merapi Yogyakarta, Indonesia. The field research was conducted using purposive sampling method where each site of geomorphological unit as representing of the cone, upper, middle and lower slopes of Mt.Merapi. Poligenesis of the soil morphology was observed at pedon P1 with composition of the upper and buried soil was Typic Hapludands-Typic Hapludands, P3 (Andic Eutrudepts-Vitrandic Udorthents), P4 (Vitrandic Udorthents -Typic Hapludands), and P5 (Andic Eutrudepts-Andic Eutrudepts). Whereas the monogenesis of the soil morphology was observed at pedon P2, P6, P7 and P8 with subgroups of Typic hapludands, Andic Eutrudepts, Andic Dystrodepts and Typic Udorthents, respectively. Soil morphogenesis diversity (polygenesis) shown by the presence of a pedon having more than one soil profile was not a limiting factor for crop roots growth, so the agro-ecosystem recovery process was relatively fast.&nbsp;</div>

<div style="text-align: justify;">Five pedons (P) were evaluated for their suitability to maize as alternate crop for the existing dominant rice crop at water scarce condition by variation in physiography, parent materials, and soil nutrients in Ponnaniyar basin. The pedons had the parent materials of non-calcareous gneiss with feldspar (P1), granite and feldspar intermingled (P2), weathered gneiss (P3), weathered quartz and felspatic gneiss (P4) and gneiss with lime (P5) with soil orders of Vertisol (P3, P5), Inceptisol (P1, P2) and Alfisol (P4). The soils were low, medium and high in available N, P and K status respectively. Based on the soil analytical report suitability of maize was established. Kunnatur, Eliyattur and Tiruchengodu series are moderately suitable (S2) for maize cultivation. Whereas, Manapparai and Pilamedu series are highly suitable (S1) for maize cultivation. Also, based on the soil fertility data, the map was generated using-the software Arc GIS 10.1 with the help of GPS information for future reference.</div>
