This study aimed to evaluate the effects of applying solid compost and coal fly ash on the improvement of Ultisol chemical properties and to determine the optimal dosage for its application. Ultisol, known for its high acidity, low organic matter content, and limited nutrient availability, requires specific amendments for optimization. The study was conducted using a factorial completely randomized design (CRD) with 12 treatment combinations: four levels of solid compost (0 t.ha-1, 2,5 t.ha-1, 5 t.ha-1 dan 7,5 t.ha-1) and three levels of fly ash (0 t.ha-1, 3 t.ha-1 and 6 t.ha-1), each with three replications. The soil that has been treated is incubated for two weeks, then the chemical properties of the soil are analyzed. The results showed that the combination of solid compost and fly ash significantly improved Ultisol chemical properties, including increasing soil pH, reducing Al-dd levels, and enhancing P-available, organic carbon (organic C), total nitrogen (total N), cation exchange capacity (CEC), and total potassium (total K). The combination of 7,5 t.ha-1 solid compost and 6 t.ha-1 fly ash provided the best results, achieving a soil pH of 5.15, an increase available P to 23.7 ppm, and a high CEC level. This combination effectively improved Ultisol quality, making it more supportive for plant growth.

Land use is one of the key factors influencing both the physical and chemical properties of soil, including characteristics such as soil color and texture. This study aimed to characterize the physicochemical properties and fertility criteria of soils under different land use types. Five land use categories were selected for investigation: shrubs, grasses, Eucalyptus sp., mixed plantations, and oil palm. Each land use type consisted of three replications. Soil sampling was conducted at five designated points per land use type, with samples collected from a depth of 0–30 cm, resulting in a total of 75 samples. The research was carried out over a three-month period from April to July 2022 using a land survey approach and purposive sampling technique. The observed parameters included soil color, texture, permeability, pH, total nitrogen (N), total phosphorus (P), total potassium (K), organic carbon (C), base saturation, and cation exchange capacity (CEC). The results revealed that the soil color was predominantly black (2.5Y 2/1), with a sandy loam texture. Soil permeability ranged from moderately fast to fast (6.33–23.68 cm·h⁻¹), while soil pH was acidic (4.75–5.11). Total nitrogen was categorized as low (0.11–0.18%), total phosphorus as very low (10.73–27.56 mg·100g⁻¹), and total potassium as very low to low (3.60–10.87 mg·100g⁻¹). Organic carbon content was low to moderate (1.49–2.45%), base saturation was very low (3.37–13.59%), and CEC was classified as very low to low (4.39–8.62 cmol(+)/kg).

Sugar palm has an economic and ecological functions. Sugar palm is also able to adapt to marginal land including tidal. This study aims to identify land characteristics for their suitability for tidal. This land survey research was carried out in the Tenayan Raya, Pekanbaru. Sampling points are based on the overlay of land system maps, soil type maps and peat depth maps. Assessment of land suitability for palm trees is carried out using the limiting factor method in actual and potential conditions. The assessment results show that the actual land suitability of all SLH is not current suitable (N1) with the limiting factor for toxicity (xc), with very high Fe levels. Limiting factors of Fe can be overcome by water management, amelioration (supplement of organic material), liming and fertilization. Potential land suitability of all SLH is marginally suitable (S3).
