The basic role of land evaluation is to assess the suitability of a land for a particular use. The student practical land of Ambon Agricultural Development School have been utilized without land an evaluation study. This research aimed to determine land suitability for of corn (Zea mays L.) and coconut (Cocos nucifera L.) and to propose the land improvement practices for the student practical land. The method used was a survey with a synthetic approach. The obervation type was Rigrid Grid with 20 m distance between lines and points observation. The results showed three land suitability classes for corn and coconut cultivation,namely S3 (marginally suitable), N1 (currently not suitable) and N2 (permanently not suitable). The limiting factors for land use were root media, nutrient retention, nutrient availability and slope. Improvement efforts to overcome the limiting factors of BS (base saturation) for the cultivation of corn and coconut could be done by liming or adding organic matter, with moderate management. The limiting factors of N-total, and P2O5 could be improved by fertilization, with a low to moderate level of management, while the slope limiting factor could not be improved due to very high costs. Based on the soil fertility criteria, the soil fertility status of the study area is low and very low.

Land Suitability Assessment

A decrease in the area of soybean farming has an effect on reducing soybean production from year to year so that it has not been able to meet the needs of national soybean consumption. Land suitability assessment is an effort to be able to optimize land use. In the process of assessing land suitability manually, it is considered inaccurate. The purpose of this study was to determine the land suitability class for soybean plants. The land suitability classification system used is the FAO land suitability classification classified at the sub-class level. Land suitability evaluation uses a matching system, as well as comparing the characteristics of land with plant growing community formulated in the technical evaluation of land guidelines for agricultural commodities. In the matching process Leibig's minimum law is used to determine the limiting factors that will affect the suitability of the class and sub-class of the land. Requirements for growing plants become kiteria in conformity evaluation. The results showed that the limiting factors of land suitability for soybean plants that had to be improved were temperature, rainfall, soil texture, C-Organic, N-Total and P-Available soil. The limiting factor of temperature and soil texture cannot be improved so that the marginal fit class (S3) on actual land suitability remains marginal fit (S3) in terms of potential land suitability.
