Rachman, LM. 2019. Characteristic and variability of soil physical properties and evaluation of soil physical evaluation in suboptimal land. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. Pp. 132-139. Palembang: Unsri Press.Â 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

Murni WS, Purnamayani R. 2019.Â Efficiency efforts and IncreasingÂ availability of nitrogen in soil on shallot (Allium ascalonicum L) throughÂ arbuscular mycorrhiza. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 186-191. Palembang: Unsri Press.Â Nitrogen is a macro nutrient that is very important in increasing plant growth and yield. Only 30-50% of N fertilizer from anorganic fertilizer that can be absorbed by plants. Shallow rooting in shallots causes inefficient absorption of nutrients from the soil both from organic matter and anorganic fertilizers. The efficiency of nutrient absorption is greater in mycorrhiza plants compared to plants that have no mycorrhiza, because of the presence and active transport of hyphae found in the symbiotic structure between mycorrhizal fungi and plant roots. The purpose of this paper is to provide information on efforts to improve the efficiency and availability of Nitrogen in the soil in shallot (Allium ascalaonicum L) through arbuscular mycorrhiza. Mycorrhizal fungi in plant roots have the ability to absorb N from organic matter in the soil. Mycorrhizal fungal hyphae can intensify other N fixing bacteria to provide N sources in the soil. Mycorrhizal fungi reduce N nutrient losses through mineralization by abundant N-fixing bacteria due to improved soil structure by mycorrhizal fungi. This is due to external hyphae of mycorrhizal fungi that provide C as an energy source of fastening bacteria N. Compatibility of mycorrhizal fungi with red onion plants allows the roots to expand absorption of nutrients by the roots so that it is expected to reduce the input of anorganic fertilizers without reducing crop yields.Keywords: arbuscular mycorrhiza, efficiency, nitrogen availability, shallots
