Polusi pertanian: Perbedaan antara revisi

[[Pestisida]] dan [[herbisida]] biasa digunakan dalam [[Pertanian|sektor pertanian]] dengan tujuan untuk membasmi [[Hama|hama-hama]] yang mengganggu pertumbuhan dan perkembangan [[tanaman]], yang berpotensi dapat mengganggu hasil [[produksi]] tanaman.<ref>{{Cite web|url=https://www.sciencedaily.com/terms/herbicide.htm|title=Herbicide|website=ScienceDaily|language=en|access-date=2020-08-01}}</ref><ref name=":0">{{Cite web|url=https://www.soils.org/about-soils/contaminants|title=Soil contaminants {{!}} Soil Science Society of America|website=www.soils.org|access-date=2020-08-01}}</ref> Tapi, penggunaan pestisida dalam sektor pertanian dapat mengakibatkan [[pencemaran lingkungan]] sekitar, contohnya seperti tanah yang terkontaminasi.<ref name=":0" /><ref>{{Cite web|url=http://www.fao.org/fao-stories/article/en/c/1126974/|title=Polluting our soils is polluting our future|website=Food and Agriculture Organization of the United Nations|language=en|access-date=2020-08-01}}</ref><ref name=":0" />

Proses [[kontaminasi tanah]] terjadi ketika pestisida yang telah digunakan menumpuk dan bertahan di [[tanah]].<ref name="Aktar 1–12">{{Cite journal|last=Aktar|first=Md.

[[Pelindian]] pestisida dapat terjadi ketika pestisida bercampur dengan [[air]] dan bergerak melalui tanah, sehingga berpotensi mencemari [[kualitas air]] tanah. Proses pelindian tersebut berkorelasi dengan karakteristik tanah dan pestisida tertentu serta tingkat curah hujan dan [[irigasi]].<ref>{{Cite web|url=https://water.unl.edu/article/crop-production/pesticide-leaching-runoff-management|title=Pesticide Leaching & Runoff Management {{!}} UNL Water|website=water.unl.edu|access-date=2020-08-01}}</ref> Pelindian dapat terjadi apabila pestisida yang digunakan larut ke dalam air; apabila kondisi tanahnya cenderung berpasir; dan apabila kemampuan adsorpsi pestisida ke tanah rendah.<ref name="Less Toxic Insecticides--UC IPM"/><ref>{{Cite web|url=https://pesticidestewardship.org/water/leaching/|title=The Problem of Leaching – Pesticide Environmental Stewardship|language=en-US|access-date=2020-08-01}}</ref><ref>{{Cite web|url=http://ipm.ucanr.edu/QT/lesstoxicinsecticidescard.html|title=Less Toxic Insecticides--UC IPM|website=ipm.ucanr.edu|access-date=2020-08-01}}</ref>

[[Organisasi Pangan dan Pertanian]] (Food and Agriculture Organizatio) [[PBB]] memperkirakan bahwa 18% gas rumah kaca antropogenik berasal dari sektor peternakan dunia. Laporan tersebut juga menyarankan bahwa emisi dari sektor peternakan lebih besar daripada emisi dari sektor transportasi.<ref name=":1" /><ref>{{Cite journal|last=Sejian|first=Veerasamy|last2=Bhatta|first2=Raghavendra|last3=Malik|first3=Pradeep Kumar|last4=Madiajagan|first4=Bagath|last5=Al-Hosni|first5=Yaqoub Ali Saif|last6=Gaughan|first6=Megan Sullivan and John B.|date=2016-03-30|title=Livestock as Sources of Greenhouse Gases and Its Significance to Climate Change|url=https://www.intechopen.com/books/greenhouse-gases/livestock-as-sources-of-greenhouse-gases-and-its-significance-to-climate-change|journal=Greenhouse Gases|language=en|doi=10.5772/62135}}</ref><ref>{{Cite web|url=http://www.fao.org/3/a-a0701e.pdf|title=livestock's long shadow|last=|first=|date=|website=www.fao.org|access-date=02-08-2020}}</ref><ref name=":1" /> Sektor peternakan dunia saat ini dipandang sebagai salah satu sumber penghasil emisi gas rumah kaca, namun perkiraan tersebut dianggap sebagai representasi yang keliru. Sementara di sisi lain, [[Organisasi Pangan dan Pertanian|FAO]] menggunakan penilaian siklus hidup peternakan hewan (semua aspek termasuk emisi dari tanaman pakan, transportasi ke proses pemotongan, dan lain sebagainya), namun mereka tidak menerapkan penilaian tersebut untuk sektor transportasi.<ref>{{Cite book|url=http://www.sciencedirect.com/science/article/pii/S0065211309030016|title=Advances in Agronomy|last=Pitesky|first=Maurice E.|last2=Stackhouse|first2=Kimberly R.|last3=Mitloehner|first3=Frank M.|date=2009-01-01|publisher=Academic Press|editor-last=Sparks|editor-first=Donald L.|series=Advances in Agronomy|volume=103|pages=1–40|language=en|doi=10.1016/s0065-2113(09)03001-6}}</ref>

[[Biopestisida]] merupakan [[pestisida]] yang berasal dari bahan alami (hewan, tumbuhan, [[mikroorganisme]], atau [[mineral]] tertentu). Biopestisida digunakan sebagai alternatif dari pestisida tradisional. Penggunaan biopestisida dapat mengurangi polusi pertanian karena aman untuk digunakan selama dalam penggunaan yang tepat sasaran.<ref>{{Cite web|url=https://www.agr.gc.ca/eng/agriculture-and-climate/agricultural-practices/agricultural-pest-management/biopesticides/?id=1531920003497#:~:text=Biopesticides%20are%20pest%20management%20agents,,%20plants,%20animals%20and%20minerals.&text=Pests%20include%20diseases,%20insects,%20mites,reduce%20crop%20yield%20and%20quality.|title=Biopesticides|last=Canada|first=Agriculture and Agri-Food Canada;Government of|date=2018-07-20|website=www.agr.gc.ca|access-date=2020-08-05}}</ref> Selain itu, biopestisida biasanya tidak terlalu berpengaruh terhadap [[invertebrata]] atau [[vertebrata]] yang menguntungkan bagi tanaman, dan lebih mudah hilang setelah digunakan dibandingkan dengan pestisida biasa.<ref>{{Cite journal|last=Montesinos|first=Emilio|date=2003-12-01|title=Development, registration and commercialization of microbial pesticides for plant protection|url=https://doi.org/10.1007/s10123-003-0144-x|journal=International Microbiology|language=en|volume=6|issue=4|pages=245–252|doi=10.1007/s10123-003-0144-x|issn=1618-1905}}</ref><ref>{{Cite journal|last=S|first=Adisoemarto|last2=M|first2=Amir|last3=A|first3=Rahayu|last4=W|first4=Anggraitoningsih|last5=Y|first5=Rahayuningsih|date=1976|title=[Side effect of pesticides on non-target animal species (invertebrates)].
