Quantity-intensity characteristics are among conventional approaches for studying potassium dynamics and its availability; this was assessed to determine availability in four districts: namely, Sodo Zuria, Damot Gale, Damot Sore, and Boloso Sore at three different land use type viz., enset-coffee, crop land, and grazing land. There was water soluble, ammonium acetate, nitric acid extractable potassium, exchangeable potassium, and non-exchangeable potassium studied in soil samples, which were collected from 0-20 cm depth of each land type. The study revealed that water soluble and ammonium acetate extractable potassium concentrations ranged from 0.04 to 0.42 cmolKg-1 soils enset-coffee and grazing land use types, respectively. The study showed that exchangeable potassium constituted the highest proportion of available potassium, while the proportion of water soluble potassium was found to be the lowest. In this study, non-exchangeable potassium concentrations varied from 0.10 to 0.04cmolKg-1soils for enset-coffee, and crop and grazing land use type. Furthermore, available potassium and exchangeable potassium concentrations were positively correlated with OC(r=0.95***), cation exchange capacity, and sand and clay(r=0.98***). In addition, the K dynamics as impacted by land use types found that the highest change in exchangeable potassium (0.31cmolkg-1soils) and potential buffering capacity (1.79cmolkg-1soils) were noted in crop land use types, whereas the lowest change(1.26cmolkg-1 soils) was observed in the enset-coffee system, The varying properties, potassium status, dynamic and land use type of soils identified in the study areas provided adequate information to design soil potassium management options and further research about the soil in each site. Therefore, application of site specific soil fertility management practices and research can improve soil potassium status and quantity intensity parameters to sustain crop productive soils.

Bukit Basa Limited Production Forest covers 125 hectares, located in Rejang Lebong District, Bengkulu Province, Indonesia.  The main function of limited production forest is to yield forest products, timber and non timber.  In Bukit Basa Limited Production Forest, there has been a change of land use from forest land to a crop land.  There has been conflict in this forest area. The objective of this study was to describe the characteristics of communities cutivating forest land and to suggest conflict resolution of this forest area. The data were collected by field observation, and interview.  The accidental sampling technique was used to select 42 respondents. Legal approaches were  used to find solutions to the tenurial conflict. The results showed that land use of Bukit Basa Limited Production Forest, in 2017 was entirely crop land. All of this forest areas have been illegaly occupied by people.  The average land area of occupied by a household was 1.24 ha. The people acquired their land by buying (4.76%), renting (21.43%), clearing the forest (42.86%), and inheriting (30.95%). The dependence of this community on the forest area was quite high. Only 38.10% of them had agricultural land outside the forest area; 61.9% depended on the land in the forest area. The contribution of farmers' incomes from agricultural business in forest land was 77.22% of their total income. The legalization of the use of limited production forests as crop lands must be enforced through policy schemes of community-based forest management, such as community forests, village forests, community plantations forest, or partnerships.

Generating land capability class guidelines at a watershed scale has become a priority in sustainable agricultural land use. This study analyzed the area of cultivated land use situated on the non-arable land-capability class in the Jema watershed in the Upper Blue Nile River Basin. Soil surveys, meteorological ground observations, a digital elevation model (DEM) at 30 m, Meteosat at 10 km × 10 km and Landsat at 30 m were used to generate the sample soil texture class, average annual total rainfall (ATRF in mm), terrain, slope (%), elevation (m a.s.l) and land-use land cover (%). The land capability class was analyzed by considering raster layers of terrain, the average ATRF and soil texture. Geo-statistics was employed to fit a surface of soil texture and average ATRF estimates. An overlay technique was used to compute the proportion of cultivated land placed on non-arable land. As per the results of the terrain analysis, the elevation (m a.s.l) of the watershed is in the range of 1895 to 3518 m. The slope was found to be in the range of 0 to 45%. The amount of estimated rainfall ranged from 1640 to 131 mm with value declined from the lower to the higher elevation. Clay loam, clay and heavy clay were found to be the major soil texture classes. Four land capability classes, i.e., II, III, IV (arable) and V (non-arable), were identified with proportions of 28.56%, 45.74%, 22.16% and 3.54%, respectively. Seven land-use land covers were identified, i.e., annual crop land, grazing land, bush land, bare land, settlement land, forestland and water bodies, with proportions of 42.1, 35.9, 8.90, 8.3, 2.6, 2.1, and 0.2, respectively. Around 1707.7 ha of land in the watershed is categorized under non-arable land that cannot be used for annual crop cultivation at any level of intensity. Around 437 ha (3.5%) of land was cultivated on non-arable land. To conclude, the observed unsustainable crop land use could maximize soil loss in upstream regions and siltation and flooding downstream. The annual crop land use that was observed on non-arable land needs to be replaced with perennial crops, pasture and/or forest land uses.

The research objective was to determine the suitability of land for a certain class of agricultural crops, namely, vanilla, oil palm, coconut, cocoa, nutmeg and cloves and to determine the direction of the crop land use. The study used survey method and analysis is to compare with criteria data suitability of land for plantation crops. Based on the results obtained twenty eight overlay land units and land units nineteen taken as a sample. The results show the suitability of land in Bacan Island of South Halmahera District for commodity crop plantations vanilla, oil palm, coconut, nutmeg and cloves in a class of land suitability is quite suitable (S2), cocoa belongs to a class of land suitability is marginally suitable (S3) with limiting factor the relative humidity. Economic analysis for all commodities is very suitable for development and Bacan Island of South Halmahera Regency.
