The use of agrochemicals is closely related to the behavior of farmers. The research aimed to study the heavy metal contamination and soil chemical properties in shallot fields and analyze the relationship between farmer behavior in using fertilizers and pesticides with a heavy metal concentration in agricultural land. The research was conducted in Srigading Village, Batul, Yogyakarta. Soil samples as many as 30 samples were taken from the shallot fields before harvest using a purposive sampling method and were analyzed for heavy metal concentrations of Pb, Cd, Ni, Co, Cr, and other soil chemical properties. Interviews were also conducted with landowners or farmers at the soil sampling location. Analysis of interview data was carried out by scoring each qualitative data into quantitative data through a questionnaire and testing the correlation between farmer behavior and heavy metal content. The results found that the shallot fields in the Srigading Village, Bantul contain heavy metals Pb, Cd, Cr, Co, and Ni with concentrations below soil quality standard. The soil organic carbon content in shallot fields has a low value. Farmer behavior has a weak negative correlation with heavy metal content in the soil.","PeriodicalId":31391,"journal":{"name":"Journal of Tropical Soils","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80168082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DRAINMOD computer model was used to simulate water levels in dry and wet climatic conditions. The principal measured parameters are soil hydraulic conductivity and drain spacing, as well as daily rainfall data. The simulation results showed that the research area belongs to the rainfed type, and the main objective of water management is to retain water and determine some efforts to increase the groundwater level through pump irrigation in the dry season. The application of pump irrigation was applied to the plant entering the generative phase. The pump irrigation was provided to distribute water into the quarter and worm (micro) channels. The effect of this application caused the groundwater level to approach about 30 cm below the soil surface, while groundwater level in areas without pump irrigation facility was in the range of 50-60 cm. Besides efforts to increase the water table, liming is still required in order to increase production. Lime application of 1 Mg ha-1 had a significant effect on increasing production.
