This study aimed to determine the land suitability for paddy plantation in Semangga subdistrict, Merauke Regency, Papua Province and to identify any treatments that needs to be taken to promote the land suitability classes. The information on land suitability is important to determine the treatment required in land preparation in order to achieve optimal production. Survey was conducted to collect necessary data which includes climate data, nutrient content (N, P, K available), Cation Exchange Capacity (CEC), pH, and toxicity. These data are interpolated within the area of Semangga subdistrict and classified based on the criteria developed by Indonesian Soil Research Institute - Ministry of Agriculture and FAO. Overlay analysis is performed in order to determine land suitability classes and the dominant limiting factor. Criteria for determining the suitability classes was taken from the lowest class of land unit. The results showed that the area of 1% (360.09 hectare) is classified as class of S2wfn, 55.8% (19,495.83 hectare) as class of S3n, 7% (2,431.83 hectare) as class of S3np, 35.3% (12,349.74 hectare) as class N1n, and 0.9% (306.6 hectare) as class of N2f. The finding of land suitability classes and its dominant inhibitory factor can be used then to determine the proper land treatment planning such as fertilization, liming, and drainage system design.

Land evaluation is one of the most important tools for integrated land use management for sustainable agricultural and land use planning. The aim of this study is to evaluate the land suitability for current land use in akkar plain- Tartous Governorate. Depending on the elevation and land use, nine soil profiles representing the main physiographic units have been chosen. Soil samples were collected for conducting some chemical and physical analyses such as: soil texture (sand%, silt% and clay%), the content of organic matter OM, Cation Exchange Capacity CEC (cmol(+)/kg -1clay). The results of the soil analysis showed that the soil texture was Clay, and the pH values were between 7.13-8.5. Furthermore, The cation exchange capacity were ranging from (12-33) (cmol(+)/kg -1clay). Results of land evaluation showed that the limiting factors either fertility factors such as high pH in the villages of Beit-kamouna, Majdaloun-albaher and Dier-hbash, or physical factors such as shallowness depth of soil. The study concluded that the suitability class ranged from S2 to N2, which emphasis the importance of reconsidering the type of land use in the study area.

Abstract Plant growth requires nutrients and their functions in plants cannot be replaced by other elements so that if there are not enough nutrients in the soil, plants cannot grow normally. The nutrient content in the soil and the ability of the soil to provide nutrients for plant growth is different. So that the type of fertilizer and the amount of fertilizer given to each type of soil will be different and it depends on the type of plant being cultivated. To determine the requirements of fertilizers and the types of fertilizers required for each type of soil, need some research about the evaluation study of soil fertility. The research was conducted in Aceh Besar with located between 5¼ 2 ‘-5¼ 8’ N and 95¼ 80 ‘-95¼ 88’E. Assessment of soil fertility status based on the criteria of several soil chemical properties, CEC (cation exchange capacity), alkaline saturation, C-Organic, P2O5 (HCL, 25%) mg / 100g, and K2O (HCL, 25%) mg / 100g. The analysis results obtained from 11 sample points show that Aceh Besar has soil fertility status from medium to low.

Chemical properties exert a considerable influence on the behavior of growing media, particularly in regulating the composition of the nutrient solution. This effect depends on the nature of components: mineral growing media are chemically inert and weakly affect the nutrient solution only in the first days of cultivation. Organic growing media constantly release and immobilize elements, playing a key role in controlling plant availability of nutrient and toxic ions. The most important chemical characteristics of growing media are cation exchange capacity (CEC), salinity, and acidity. These can be changed using amendments. The chapter examines these chemical properties of growing media and growing media components, describes how they can influence soilless cultivation and analyzes latest trends in their management. Finally, a case study on the modification of pH, salinity and nutrient content during storage of two growing media is reported.

Ultisol soil has high potential for the development of dryland agriculture. However, this soil use faces obstacles because the nutrient content in Ultisol soils is generally low. This study aims to determine the effect of manure and straw compost on increasing nutrient content of phosphorus in ultisol soil. This study used a completely randomized design (CRD) with 9 levels of treatment, namely P0 = control, P1 = manure 10 tons / ha, P2 = manure 5 tons / ha, P3 = compost 5 tons / ha, P4 = compost 10 ton / ha, P5 = manure 5 tons / ha + compost 10 tons / ha, P6 = manure 10 tons / ha + compost 5 tons / ha, P7 = pellet compost 5 tons / ha, P8 = compost pellets of 10 tons / ha. The treatment was repeated 3 times. The results showed that giving 10 tons / ha of manure plus 5 tons / ha of compost had a significant effect on reducing Al-dd content, and increasing P-available, pH, base saturation, cation exchange capacity and C-organicon Ultisol soil. Giving pellet fertilizer 10 tons / ha gives a real influence on the growth of maize plants.
