The agricultural sector is still the leading sector of the economy in Wonosobo Regency. Its superior commodities include paddy rice, tea, tobacco, coffee, and vegetable plants. In the practice of agricultural activities, it is inseparable from the use of inorganic fertilizers and persistent chemical pesticides that cause heavy metal contamination in agricultural land. Industrial waste around agricultural land that enters the water body also contributes to the accumulation of heavy metals in the soil of the water for irrigation. This study aimed to determine the distribution of heavy metal content of Pb, Cd, Ni, Co, Cr, and As on the agricultural land of Wonosobo Regency. The study was conducted on the agricultural land of Wonosobo Regency. As many as 312 soil samples were taken from a layer of sports (depth of 0-20 cm) of agricultural land in ten sub-districts of Wonosobo Regency. Soil sample analysis included heavy metals Pb, Cd, Ni, Co, Cr, As, organic Carbon, CEC, and soil texture. The analysis was carried out in an integrated laboratory, the Agricultural Environment Research Center. The results showed the concentration of heavy metals detected in Wonosobo Regency agricultural land respectively Pb > Co > Ni > Cr > As > Cd. These heavy metals in the soil are still in normal concentrations and are safe for agricultural land.

Shallots have been widely planted as the primary commodity crop in Brebes Regency, Central Java, Indonesia. Information on the distribution of heavy metals in the shallot fields of Brebes Regency, Central Java, Indonesia, is not yet available. Hence, the present study was conducted to identify the concentration and spatial distribution of several heavy metals (Pb, Cd, Co, Cr, and Ni) and their possible sources in the shallot fields through a field survey and a series of laboratory and statistical tests. The total concentration of heavy metals was analyzed from 184 sampling points of the shallot fields in Brebes Regency, Central Java, Indonesia, during the dry season from August to October 2019. The heavy metals concentration was as follows: Cr > Ni > Pb > Co > Cd. The values of total Pb, Cd, Co, Cr, and Ni concentrations in the soils were 7.84–18.94, 0.99–2.31, 3.02–9.98, 10.40–49.55, and 10.17–26.62 mg kg−1, respectively. All these concentration values of heavy metals are still lower than the critical values for agricultural soils and lower than the topsoil background values except Cd. Based on the concentration of heavy metals, the shallot fields in Brebes Regency, Central Java, are classified as uncontaminated soils. Multivariate and geostatistical analyses were employed to determine and describe the metals’ origin. Pb, Cr, and Ni mainly originate from a natural source, while Cd and Co are from anthropogenic sources (agricultural practices and industry).

Cobalt (Co) is considered a beneficial element for plants. However, when soils contain excessive amounts of Co, it could cause phytotoxicity. Despite this, the current status of Co in Sri Lankan rice-cultivated soils is not known. Therefore, this study was conducted to (i) determine the distribution of exchangeable Co concentration, and (ii) examine the interactive effects of climatic zone (CZ), agro-climatic zone (ACZ), soil order, water source, and their interactions in determining exchangeable Co concentration in lowland rice fields in Sri Lanka. A total of 8,292 soil samples representing six ACZs, six soil orders, and three water sources were collected using a stratified random sampling approach. Cobalt was extracted in 0.01 M CaCl2 and measured using Inductively Coupled Plasma Mass Spectrophotometry. Exchangeable Co concentration ranged between 0.03-2,409 μg kg−1 with a mean value of 185.9 μg kg−1. Over 77.5% of the soil samples tested were Co deficient, i.e. <250 μg kg−1. Samples collected from the Intermediate zone, particularly Intermediate zone Mid country, had higher Co concentration than that reported in other ACZs (p<0.05). Among the soil orders, Histosols had higher (232 μg kg−1) and Vertisols had lower (91 μg kg−1) Co concentrations (p<0.05). Moreover, Co concentration was negatively correlated with soil pH (r=−0.3391, p<0.0001) and rice crop productivity (r=−0.1512, p<0.0001). Although exchangeable Co concentration in rice cultivated soils was low, it is important to implement strategies such as proper waste management, treatment of industrial effluents, and the use of safer and more sustainable practices in the chemical and mining industries to minimize further accumulation of Co exceeding the critical limit (i.e. 30 - 40 mg Co kg−1 rice grain), and to ensure the safety of rice production in situations where geological and anthropogenic activities can increase soil exchangeable Co concentration.
