Abstract

Soils in Indonesia are mostly classified as Ultisol having physico-chemical properties such as low pH, low organic matter and very low in nutrients. As a result, the agricultural production on land is very low. Today the use of chemical fertilizers without addition of organic matter to cause a decline in soil organic matter content, soil physical properties become increasingly hard due to structural damage and no development of most soil microorganisms. In such conditions, the soil becomes no more responsive to fertilization so that agricultural production including food crops is leveling of. Therefore, efforts to overcome the barriers of soil properties to increase production of food crops must be done. Recently busy talking people active ingredients that can increase agricultural production spectacular. The material is humic acid extracted from organic materials. The result of this study showed that application of 10 liter/ha humic acid to the soils through zeolite as carrier increased the production of paddy by 15% and corn by 10%. The increase of crop production is due to the development of root then stimulating the absorption of nutrients

Abstract

This research was aimed to determine the differences of physical and chemical characteristics from three natural zeolites from Tasikmalaya, Bayah and Lampung areas and to examine the characteristics of the natural zeolite adsorption capability to the micro-nutrients. The zeolite characterization analysis included some variables i.e. mineral types, morphologyand pH, CEC (Cation Exchange Capacity), BSP (Base Saturation Point), Cu and Zn content of zeolite. Analysis of natural zeolite adsorption characteristics were done by Batch System. Data interpretation were done by using the isothermal adsorption equation of Langmuir, Freundlich and Brunauer-Emmett-Teller (BET).The results showed that zeolite from Bayah and Tasikmalaya had a similiar morphology and it was categorized as mordenite types and platy structure, while zeolite from Lampung was a clinoptilolite type and tabular structure. The CEC of Tasikmalaya zeolite (137.58 cmol(-)kg-1) was higher than Bayah (96.75 cmol(-)kg-1) and Lampung (87.72 cmol(-)kg-1). Adsorption capability at the Langmuir equation of Cu by Bayah zeolite (47.619 mg g-1) was higher than Lampung (33.333 mgg-1) and Tasikmalaya (28.571 mg g-1). Effective adsorption of Zn by Bayah zeolite 19.417 mg g-1 was higher than Lampung (16.949 mg g-1) and Tasikmalaya (1.395 mg g-1).
