Ifilimu yepulasitiki iye yandisa kakhulu isivuno sezolimo ngokusiza ekwandiseni isivuno, ukonga amanzi, nokunciphisa ukusetshenziswa kwezibulala-zinambuzane. Iyaqhubeka nokusetshenziswa kakhulu ekutshalweni kwe-asparagus, ama-strawberries, nemifino. Ucwaningo olwenziwa yiNyuvesi yase-Augsburg eholwa ngu-Alessandro Fabrizi lusebenzise idatha yesathelayithi okokuqala ngqa ukurekhoda ngokunembile uhlobo olusabalele lwaleli "siko lepulasitiki" eJalimane. Imiphumela, eshicilelwe kujenali ethi "Imibiko Yesayensi," ibonisa ukusetshenziswa kwepulasitiki ezingeni lenkundla, kuyilapho izilinganiso zangaphambilini zinikeze idatha enzima kuphela ezingeni lesifunda noma lesifunda.
Ngokuhlanganisa izithombe zesathelayithi ezitholakala ngokukhululekile ze-wavelength kanye ne-radar ngokufunda komshini, izinhlobo ezimbili eziyinhloko zokusetshenziswa kwepulasitiki zikhonjwe. Amafilimu epulasitiki we-mulch amboza ngokuqondile inhlabathi ukuze andise izinga lokushisa lomhlabathi, agcine umswakama, futhi acindezele ukhula. Izembozo zepulasitiki ezifana nezindlu zokugcina izithombo noma ama-polytunnels zivikela izitshalo ezakhini futhi zidale izimo zokukhula ezifanele. Ngo-2020, cishe amahektha ayi-140.000 amafilimu anjalo aqoshwa eJalimane—indawo ephindwe nengxenye ubukhulu beBerlin. Uma kuqhathaniswa nezilinganiso zezibalo zezolimo zango-2019, ezibonise cishe amahektha ayi-100.000, idatha yesathelayithi inikeza ukuqapha okunembe kakhudlwana phakathi neminyaka embalwa. Naphezu kwezinzuzo zabo, amafilimu epulasitiki afaka izingozi ezinkulu zemvelo, njengoba ngisho nalapho ziphathwa kahle, izingcezu zepulasitiki zingangena emhlabathini, ikakhulukazi ngamafilimu amancane e-mulch, avame ukungasuswa ngokugcwele noma asetshenziswe kabusha ngemva kokuvuna. Ngakho-ke ukuqoshwa okunembayo kwezindawo ezisetshenzisiwe kubalulekile ekuhloleni imithelela yemvelo kanye nokuthuthukisa izindlela zokulwa.
Ucwaningo lubonisa amandla edatha yesathelayithi nokufunda komshini ukuze kuqashwe ngokuphelele imvelo. Ihlinzeka ngesisekelo sedatha esibalulekile sezinqumo zezepolitiki futhi ingasiza abalimi ukuthi basebenzise ifilimu yepulasitiki ngokuqhubekayo.
