This study aims to: (1) to know the suitability of the land for the development of several fruit horticultural commodities in the Sub-district of South Kuta, (2) determine the suitability of land in agroecosystem and its limiting factors, (3) provide ecommendations for land management in the study area. The study used a field survey method with the determination of observation samples carried out in a stratified purposive sampling with land units as the strata. Land quality/characteristics as a determinant of land suitability observed include: annual mean temperature, water availability; rooting media; availability of oxygen; nutrient retention, CEC, BS, pH, and organic matter; nutrients available; erosion; flood hazard; land preparation. Land suitability assessment is done by matching the land quality with the growing requirements for the plants evaluated. The results showed that the actual land suitability for food crops of fruit horticulture (citrus, mango, starfruit, banana, sapodilla, grape, klengkeng, papaya, grain guava, guava, jackfruit, soursop, avocado, srikaya, breadfruit and pineapple) belonged according to conditional marginal suitable (S3), until not appropriate (N) with the quality of the land as a limiting factor are: rooting media (effective depth of soil); land preparation (surface rocks and rock outcrops); erosion hazard; and nutrient availability (especially N-total and P-available). The assumption is that some land quality/characteristics that are as limiting factors can be improved, then the suitability of the potential land is quite suitable (S2) to marginal suitable (S3) with the quality/characteristics of the land as a limiting are: availability of water (long dry months), rooting media (effective depth), land preparation (surface rocks, rock outcrops), and nutrient retention (rather high soil pH). Increased land productivity in the study area can be done by improving land management by providing inputs such as: the addition of sufficient organic material, adition of fertilizer containing elements of N (ZA), and fertilizer containing elements of Potasium (SP36), taking conservation measures in the form of making terraces on sloping lands.

Agroforestry Practices

The present paper highlights the importance of hedgerows and enclosures in the mountains of Central Spain. Now, these landscapes have suffered profound variations in terms of agroforestry practices, especially in the Mediterranean mountains where the characteristic multifunctional has largely been lost. The article analyzes land uses changes, dynamics, and their morphological features between the first half of the 20th Century (1956) and the second decade of the present time (2019). The paper was divided into three sections. First, the identification of land uses using orthophotograph and aerial photograph; after that the info was checked with fieldwork. Eleven categories were identified according to the dominant use and land use changes and size of land parcels were taken into consideration. Second, the configuration and the information collected through the type and intensity of change in land uses made it possible to recognise and quantify their distribution and trend between these two dates. Also, the kernel density algorithm available in the Arcgis 10.5 software was used to obtain density and changes in land parcels. Finally, an overview is given of the main role that this agroforestry plays due to the social, ecological, and economic benefits that they provide for allowing sustainable development.
