The rain-fed rice fields in Umbu Pabal Selatan Village are agricultural land that is always cultivated every year to meet the food needs of the villagers. Soil fertility is a piece of important information in managing rice fields to increase rice production. This study aims to evaluate the status of soil properties, soil fertility, and the direction of management of rain-sized rice fields in the village. The method used was descriptive exploration surveys with soil samples taken deliberately. Laboratory test results showed that soil pH is classified as acidic, N-total is medium, P-available is low, K-available is very high, cation exchange capacity is high, and C-organic is high. Fertility status is low (96.9 ha), moderate (194.6 ha), and high (160.3 ha). Management direction in improving fertility and nutrient deficiency is by fertilizing and water-logging.   Keywords: rain-fed rice field, soil fertility, South Umbu Pabal Village

Ultisol is one of the soils with limited physical characteristics. The water content is low, the permeability is not enough to pass water into the soil, and the organic-C content is classified as moderate. So that it affects the soil in storing low water, one solution to overcome the physical characteristics of is to provide organic matter into the soil. The purpose of this study was to determine the physical characteristics of Ultisol and to determine the effect of the combination of organic matter from cow dung and rice husk ash on the soil water holding capacity of ultisols on dry land. This study was conducted at the Laboratory of Wira Wacana Christian University, Sumba. This study used a completely randomized design with six treatments and four replications. Observation data were subjected to analysis of variance followed by LSD advanced test with a confidence level of 5%. The results showed that the application of organic matter on the soil significantly affected water content, field capacity, permeability, and C-organic. The application of organic matter can improve soil structure, not soil texture gave a very significant effect, and the treatment that had the best water content was 75% cow dung + 25% rice husk ash.

Lewa sub-district is one of the sub-districts in East Sumba Regency, which has dry land that can be maximized for the development of porang plants and development purposes; information on the potential of porang plantations is needed. This study aimed to determine the biophysical characteristics of the land and the land suitability class of porang plants. The analytical method used was the matching method by comparing the land characteristics and plant growth requirements and the overlay method. The matching results show that the land characteristics in Lewa Subdistrict are class S1 (Very suitable), covering an area of 26.220,209 ha and Class S2 (quite suitable), covering an area of 3.608,523 ha. Limiting factors in this area are water availability (OA) such as drainage, nutrient retention (nr) such as CEC and pH, and erosion hazards (eh) such as slope.
