Abstract

Farmers use pesticides intensively in the cultivation of rice. The use of organic and inorganic fertilizers give in large quantities. Pesticides, organic and inorganic fertilizers contain heavy metals arsenic, so the provision of large amounts will accumulate in the soil. In addition to nutrients, rice plant tissue will absorb heavy metals including arsen. Indonesian government has implemented a quality standard of arsen in cerealia by 0.5 mg kg-1. This study was aimed to obtain quality standard of arsenic in an Inceptisol at planting of rice. Research conducted at the scale of pot to contaminate soil planted rice with rows 0 mg kg-1, 15 mg kg-1, 30 mg kg-1, 60 mg kg-1. Data observed that plant growth, yield and content of arsenic in the soil and plant tissue. Agronomic parameters and yield components performed statistical analysis of variance followed by Tukcey test. Growth and crop yield based on statistical analysis are significantly different. The quality standard of heavy metals on soil done by regression analysis between the content of arsen in the soil and rice seed. By incorporating quality standards of arsenic on the rice on the regression equation, obtained the quality standard of arsen in the soil. The analysis results obtained that the quality standards arsenic in an Inceptisol of Grobogan in the soil planting of rice of 17.5 mg kg-1.

Abstract

Fertilizers and pesticides application in the agricultural sector provide a significant benefit in agricultural production. However, the use of fertilizers and pesticides continuously can be a harmful effect on the condition of the agricultural environment and the living things around it. Heavy metal pollution from the use of fertilizers and pesticides can cause health problems in humans, animals, and soil. Nickel is a dangerous heavy metal. The purpose of this study was to obtain the value of nickel-metal quality standards in two types of soil texture with rice as an indicator plant. This nickel quality standard testing activity was carried out in 2018 at the Indonesian Agricultural Environment Research Institute. Light textured soil was obtained from Bantul and heavy textured soil from Lamongan and Ngawi. Soil samples were tested for the adsorption of heavy metals using the Langmuir approach. A pot experiment was conducted at the screen house for heavy metals calibration in the soil. The results of the regression of the nickel content in the soil and rice can be seen as the quality standard value. Estimated quality standards in light-textured soils (Bantul) was 1.388 mg kg-1, heavy-textured soils (Lamongan and Ngawi) was 1.855 mg kg-1 and 1.697 mg kg-1, respectively. The value of nickel-metal quality standards in the clayey soils are higher than those in the light-textured soils
