Unistavanje korova.

Korov je biljka koja samoniklo i raste tamo gde je covek ne zeli u agroekosistemima.
Korov je nepozeljan jer gajenim, odnosno kulturnim biljkama oduzima prostor, vodu, minerale iz djubriva, pa i svetlost. Ipak, neke korovske biljke mogu biti veoma dekorativne, neretko lekovite, pa cak i jestive. Bez obzira na to, covek se trudi da ih odstrani iz agroekosistema.
Uglavnom se protiv korova primenjuju takozvane agrotehnicke mere, ali i hemijske. Hemijske mere se sprovode brze, ali njihovim primenjivanjem postoji rizik od zagadjivanja prirode i po ljudsko zdravlje. Hemijska sredstva koja se koriste protiv korova nazivaju se herbicidi.
Dan je bio sa oblacima, meteorolozi su najavili kisu.



Weed control.

Weed is a plant that grows wild and grows where man does not want it in agroecosystems.
Weeds are undesirable because they take away space, water, minerals from fertilizers, and even light from cultivated or cultivated plants. However, some weeds can be very decorative, often medicinal, and even edible. Nevertheless, man is trying to remove them from the agroecosystem.
The so-called agro-technical measures are mainly applied against weeds, but also chemical ones. Chemical measures are implemented faster, but by applying them there is a risk of pollution of nature and human health. Chemicals used against weeds are called herbicides.
The day was cloudy, meteorologists announced rain.
