Peanut is a plant that has an important role in land and has a high selling value. Therefore it is necessary to take appropriate steps to develop peanut cultivation in the Panasen Sub-watershed by knowing the level of land suitability. The problems faced by the community are 1) lack of interest in the community to plant peanuts, 2) land-use change from agricultural land to lodging land 3) land evaluation has never been carried out for peanut plants in the area. The study used a land unit approach supported by soil analysis, plant growth requirements, and matching. The results showed that the research area was classified as suitable for peanut plants with a suitability class S2 (quite suitable) with a total of 4 land units, namely S2rfns (945.41 ha), S2sn (1675.15 ha), S2srn (938.05 ha), S2sn (13.45 ha) and class suitability of S3 (according to marginal) with 2 land units, namely S3s (12.95 ha), S3s (15.67 ha). The limiting factors for suitability class S2 are root media (r), nutrient retention (f), nutrient availability (n) and terrain (s). The limiting factor for suitability class S3 is the field (s). The limiting factor for N1 land suitability is nutrient availability (n), root media (r) and terrain (s). The limiting factors for conformity class N2 are the field (s) and the rooting medium (r).

Pepper (Piper nigrum L.) has a high selling value. The price of pepper in the domestic or international market that is always high can be a great opportunity to increase farmers’ income. Tirtomoyo District is dominated by hilly areas with common soil types of Litosol and Latosol. As one of the efforts to develop the regional economic rate, especially in hilly areas, pepper cultivation can be a solution offered by the agricultural sector. The study was conducted using an explorative descriptive survey method consisting of field observation and laboratory analysis. The analytical unit used was Land Map Unit (LMU) obtained from soil map. The sampling sites were selected using purposive sampling method according to the research objectives and representing the study area. The results show that the actual land suitability for pepper in Tirtomoyo District is marginally suitable (S3) for all LMU. The main limiting factors are water availability and nutrient availability, thus the Tirtomoyo district still have potency for pepper cultivation by applying some improvement measures such as fertilization, irrigation, organic material addition, and cover crop planting.

The suitability evaluation of agricultural land at the regional scale is of great significance for protecting land and water resources and building sustainable agricultural systems. Based on climate, soil, topographical, and surface water resources, land suitability index (LSI) data for maize, rice, and soybeans are established using an analytical hierarchy process and matter element analysis (AHP–MEA) model in Jilin Province, China. The results show that there is a significant positive linear correlation between the LSI and the measured yield, which indicates that the model has an ideal effect and certain reference and extension significance. The main limiting factors for maize and soybean planting are pH, total nitrogen (TN), available phosphorus (AP), and soil texture, while water shortage limits rice planting. Different spatial structure optimization schemes for planting are established using the LSI and measured yield, along with economic indices. This study shows that the scheme that integrates policy and cost can make full use of land and water resources and promote the economic growth of agriculture. After optimization, the planting areas of maize, rice, and soybeans were 7.22, 2.44, and 0.71 million ha, respectively, representing an increase of 15.71 billion yuan over the agricultural GDP for the existing planting structure. It is expected that this study will provide a basis for follow-up studies on crop cultivation suitability.

Land suitability assessments can provide useful information to help optimize agricultural land use. Due to the current lack of appropriate land management practices in the Fakkeh region, southwest Iran, a land suitability evaluation study for key agricultural crops, including wheat, alfalfa, maize and barley, covering 43,700 ha was undertaken. Qualitative evaluation was carried out using two methods, the simple limitation and parametric methods (Storie and square root method), to compare land and climate characteristics with crop needs. The most important limiting factors in wheat, alfalfa and barley production included the physical properties of the soil, especially light soil texture. The major limiting factors in maize production were low relative humidity and high n/ N ratio during the plant growth period, light soil texture, soil salinity and alkalinity.

AbstractThe Department of Agriculture and Fisheries for Scotland (DAFS) have a responsibility to comment on all proposed changes of use in agricultural land in Scotland, whether this be to urban and industrial use or to forestry. The Macaulay Institute for Soil Research, through its Department of Soil Survey, has mapped the soils of Scotland, demonstrating in the process very clear links between the underlying solid and drift geology, and soil development and land use. Two series of interpretative maps have been produced, one at 1:250 000 of the entire country and one at 1:50 000 of the arable lands. These incorporate both climatic and site factors with soil type to provide a classification of agricultural potential. This work will be implemented in Scotland by DAFS as part of their planning-related functions in 1987. This paper describes the links between geology and soil maps, and the approaches taken in both land classification compilation and application. In conclusion, the basis for land suitability maps for specific purposes, now being actively developed to provide further guidance for assessing the impact of land use change in Scotland, is described.

Abstract Agriculture plays an important role in Indonesia development. Between the years 2020 - 2024, the government targets food security on sustainable development goals. Food estates have been made in several areas. However, there are constraints such as peatland and low elevation. Various irrigation systems developed by inhabitants and government called Handil, the traditional water management system applied to irrigate rice fields using tidal river system. One of the Handil in Central Kalimantan is called Handil Rakyat Palingkau in Kapuas which can control irrigation area for around 1397 ha. Agricultural land suitability analysis is needed to ensure land suitability based on land quality in requirements and planning. In this study, land analysis was determined using FAO parameters which were analyzed based on temperature, soil type, soil nutrient retention, hydro-topography, safe from flooding, and water quality. The results showed that the relevant aspects for rice were salinity, peat thickness, inundation, TDS, pyrite depth, and hydro topography. However, some aspects are unsuitable for rice that need more attention, such as pH, temperature, and soil nutrient retention.
