“…Geographic information system (GIS) is a powerful tool which helps to integrate many types of spatial information such as agro-climatic zone, land use, soil management, etc. to derive useful information (Adornado and Yoshida 2008 Furthermore, GIS generated soil fertility maps may serve as a decision support tool for nutrient management (Iftikar et al 2010). A number of studies on soil fertility mapping have been documented (Ravikumar et al 2004) but no study was made including more than one watershed across a climatic gradient.…”

Soil fertility parameters viz., pH, electrical conductivity (EC), available macro-and micronutrients were determined in soil samples drawn at 300 m grid intervals from three micro-watersheds representing northern dry zone (zone-3), northern transition zone (zone-8) and hilly zone (zone-9) across a climatic gradient in Belgaum district of Karnataka. Based on the data maps were prepared in GIS environment using Arc GIS v 10.0. The soil fertility parameters clearly reflect the agro-climatic conditions under which the soils are formed. Soils of zone-3 were alkaline (pH> 8.5), soils of zone-8 slightly alkaline (7.0-8.5) and those of zone-9 slightly acidic (5.5-6.5). Whereas carbon and available nitrogen (N) in soils of both zone-3 and zone-8 were low, organic carbon (OC) was high (6.9 g kg -1 ) but the available N was medium (412 kg ha -1 ) in soils of zone-9. Available phosphorus (P) remained low in zones-3 and zone-8 but was marginally medium in zone-9. The available potassium (K) status of zone-3 soils was high (401 kg ha -1 ) but was medium in zone-8 and zone-9. Available sulphur (S) was low, DTPA extractable Zn and Fe was deficient, and Mn and Cu was sufficient in soils of both zone-3 and zone-8. In zone-9, however, available S and Zn were marginally sufficient but Fe, Mn and Cu were distinctly sufficient. In conformity with mean values described above, OC, available N, P, S and Zn were low (100% area for each) and available K was high in 91.2% area in soils of zone-3. Similarly for zone-8, OC and available N was low in 2/3 of area, available P was low in 76.5% area, available K was medium in 92.0% area, and low in available S (10%), deficient in Zn (99.1% area) and Fe (100% area). In agreement with means a large area under high OC (66.2%) and medium in available N (81.2%) and low in P (71.7%) was reflected in maps of zone-9. However, available K, S and Zn were distributed equally between low and medium classes despite K being medium and S being low and Zn being sufficient suggesting maps are preferred over means. The pH was slightly lower, OC and available N distinctly higher, and available P and DTPA extractable Cu lower in forest lands compared to agricultural lands in zone-9. Land use did not influence available K and DTPA extractable Zn, Fe and Mn.

“…The findings of the land suitability for cacao development in Keerom Regency are shown in Table 1, and the distribution of land suitability for cacao is shown in Figure 4. The appropriateness of the land is an important aspect in increasing a plant's productivity [12]. As a result, growing cacao on appropriate terrain in Keerom Regency is likely to boost cacao production.…”

Cacao is a primary commodity in the Keerom Regency, but production has been decreasing in recent years. Cacao cultivation on unsuitable land and without cutting-edge technology would impede efforts to increase its productivity. The study aimed to evaluate land suitability for cacao in Keerom Regency, Papua, and to suggest site-specific technologies. The study was carried out in the Keerom Regency of Papua in 2015. Land suitability assessment was carried out by matching data on land characteristics (climate, slope, soil type, and soil fertility) with land use requirements for cacao cultivation. The data was analyzed using geographic information systems. The result showed that 78.077 ha (8.60%) of the studied area were highly suitable for cacao cultivation, 123.645 ha (13.63%) was moderately suitable, and 389.603 ha (42.94%) was marginally suitable. About 316.082 ha (34,83%) of the studied area was classified as not-suitable. The recommendation technology for increasing cacao yields were fertilization, pruning, shade management, and individual terraces. Cultivation on suitable land and the application of technological innovations are expected to increase cacao production in Keerom Regency, Papua. The findings of this study could be used as a reference for policymakers to establish cacao development in the future.

The aim of this research work was to map the status of soil nutrients in the Bisankhel catchment of Chitlang VDC, Makawanpur, Nepal. The study area covered 1023.25 hectares of land, extending from 85°8'8.433"E to 85°10'10.198"E longitude and 27°37'24.251"N to 27°40'21.560"N latitude. Total Nitrogen (N), available Phosphorus(P), extractable Potassium (K), soil organic matter (SOM) and soil pH were measured for 50 soil samples collected using random sampling representing different land uses in the study area. Most of the samples were found very acidic where uplands (4.879±0.119) were more acidic than lowlands (5.036±0.0973). Most samples upon analysis were found to be medium in SOM and total N. SOM was slightly higher in lowlands (3.385±0.256%) than in uplands (3.05±0.206%). Total N was also slightly higher in lowlands (0.145±0.00634%) than in uplands (0.127±0.00639%). Similarly, Available P and K were found very high in majority of the soil samples. Available P was slightly higher in lowlands (92.34±16.96ppm) than in uplands (71.58±15.47ppm). However, extractable K was slightly more in uplands (269±31.32ppm) than in lowlands (240.4±23ppm). Spatial prediction using various interpolation methods was performed in ArcGIS 10.5 software platform using 'Geostatistical Analyst' extension. The predicted values in raster data structure were used for mapping the soil fertility status of the catchment. Different interpolation methods were evaluated following crossvalidation approach. Comparison of prediction errors was carried out to select the optimum prediction methods for the interpolation of soil nutrient values. Completely Regularized Spline and Ordinary Kriging methods were found to yield better prediction of soil nutrient status among the Deterministic and Kriging methods respectively. Soil pH being the limiting factor, pH control was necessary.
