Pesticides Usage in the Soil Quality Degradation Potential in Wanasari Subdistrict, Brebes, Indonesia

Abstract

Uncontrolled application of pesticides can contaminate soil and may kill other nontarget organisms. This study aims to determine the usage pattern of pesticides by farmers in Wanasari Subdistrict and study the soil quality degradation potential. This study was a quantitative and qualitative research. Sources of data were collected from observation, questionnaire, and in-depth interview methods. The respondents were shallot farmers who planted shallot during 2013-2016 ( = 60). In-depth interview was done with three respondents from the local agricultural extension center (BPP). This study found that there were some different types of insecticides and fungicides that were used in every planting season. The farmers applied pesticides in large amount once every three or four days. They mixed minimally three insecticides and fungicides types about 30-40 ml for each type. Organophosphate residues that were found in soil samples were methidathion residue about 0.014 mg/kg, malathion residue ranging around 0.1370-0.3630 mg/kg, and chlorpyrifos residue in the range of 0.0110-0.0630 mg/kg. The excessive application of pesticides showed the land degradation potential. Soil quality laboratory testing is recommended to ensure the agricultural land condition. Routine assessment of soil quality and pesticide usage control is recommended to keep sustainable ecosystem.

Identification of Soil Properties and Organophosphate Residues From Agricultural Land in Wanasari Sub-District, Brebes, Indonesia

“…Wanasari District as the region with the highest onion production in Brebes Regency is able to produce 1,025,680 Kw, the average production is 144.97 Kw / ha [1]. According to previous research conducted by Joko T, et al (2017) that onion farmers in Kecamatan Wanasari use large amounts of pesticides, and average to apply pesticides every three or four days. The use of pesticides in large numbers is due to onion plants are very vulnerable to pests, so farmers must apply insecticides to prevent damage to the plant.…”

“…Sequel to application of these chemical compounds on farm lands to achieve the essential mission to care for crops, they have been reported also to compromise water quality [1]. They move into the surrounding water bodies, therefore having a widespread effect on the physical, chemical and biological processes within aquatic ecosystems [2].…”

“…Dampak negatif yang terjadi terhadap manusia dan lingkungan disebabkan oleh perilaku petani yang kurang bijaksana. Petani mengaplikasikan pestisida setiap 3 atau 4 hari sekali dan juga mencampurkan beberapa jenis pestisida dalam satu aplikasi (Joko et al 2017).…”
