Rachman, LM. 2019. Characteristic and variability of soil physical properties and evaluation of soil physical evaluation in suboptimal land. In: Herlinda S et al.

Palembang: Unsri Press. Self-reliance of food depends on how to optimizing dry land farming, especially enhancing productivity of soils in suboptimal lands. It needs strong direction and recommendation of soil management. Nowadays, soils on suboptimal lands encountered soil chemical, biological and physical problems to support optimal plant growth and production. Problems that are often arising are soil acidity, low availability of soil nutrients, low carbon organic content and low soil ability to serve available water for plant. The excellence fertilization technology is believed to be able to overcome the chemical aspects problems such as low of soil pH, soil nutrients and carbon organic content. However, problems related to soil physical properties are more difficult to be solved and need a longer period process for recovering, amendment and improvement. Correspondingly, a deep research needs to study the characteristics and variability of soil physical properties and soil physical quality of suboptimal lands. The purpose of study was to assess the characteristics and variability of soil physical properties and to evaluate soil physical quality on suboptimal lands. Soil physical properties that affecting soil physical quality analyzed is directed to aspects related to root development in soil, available water supply, and soil aeration, particularly soil depth, drainage, texture, bulk density or soil compaction, porosity, and soil pore distribution that controls the ability of soil to hold water, supply available water, release water and pull water very strong. Results of study conducted in 60 locations of suboptimal land, spread in 3 regencies and 2 cities in Banten Province and 6 regencies in West Java Province, showed that majority of their soil physical quality belong to moderate class. In fact, almost all of the soil physical properties that were studied did not show severe handicap for plant growth and production.Keywords: soil physical evaluation, soil physical properties, soil quality evaluation, suboptimal land

Abstract

Rachman LM, Baskoro DPT, Wahjunie ED, Nurmilah A, Astriani T, Dewi NM. 2019. Evaluation of the physical properties of controlling soil capabilities holding water and supplying water for plants and its association with agricultural management on sub-optimal lands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 111-120. Palembang: Unsri Press. Utilization and optimization of marginal land or sub-optimal land is needed to support the government's food security program. Rainfed sub-optimal land, although quite extensive (2,247,527 ha) and still potential enough to be utilized. However, the current low productivity due to a variety of biophysical constraints, required input and recommendation technology appropriate land management to increase productivity. Sub optimal rainfed land including dry land. One serious obstacle faced is often experiencing water shortages or droughts during the dry season. However, the current low productivity due to a variety of biophysical constraints, required input and recommendation technology appropriate land management to increase productivity. Sub optimal rainfed land including dry land. One serious obstacle faced is often experiencing water shortages or droughts during the dry season. The lack of water in the plant root zone can basically be caused by: 1) lack of water supply, 2) low soil capacity to hold and supply water for plants, or 3) a combination of both. For this reason, it is necessary to have accurate and comprehensive data and information about the ability or capacity of the soil to hold and store soil water holding capacity. The purpose of this study is to examine the characteristics of physical properties of land in sub-optimal land that controls the ability or capacity of the soil to hold or hold and store water so that directions can be arranged for agricultural management in sub-optimal lands to increase productivity. The location of the study whose data was reviewed in this study included the areas of Bogor, Lebak, Pandeglang and Serang. Some of the soil physical properties studied were soil bulk density, soil texture, stability of soil aggregate stability index, total soil porosity, distribution of soil pores, and soil organic matter content. Evaluation results indicate that in general the characteristics of the physical properties of the soil associated with its ability to supply water are available to plants and hold and store water are classified as moderate. Directions for recommendations for processing and managing soil for agricultural management are adjusted to the conditions and characteristics of the soil.Keywords: agricultural management, land management, soil physical properties, sub- optimal land, soil water holding capacity
