Soijapelto Brasiliassa


Monokulttuuri on yhden kasvilajin viljelemistä. Esimerkiksi vehnäpelto tai istutusmetsä on tällainen. Jos viljelykasvi on sama useampana vuotena peräkkäin monet tuhoeläimet, kasvitaudit ja rikkakasvit runsastuvat pienentäen viljelykasvin satoa.


Sadon määrä alkaa pienentyä jo kolmannen viljelyvuoden jälkeen muutaman prosenttiyksikön vuodessa. Pitkäaikaisessa yksipuolisessa viljelyssä se on noin 15–30 % vuoroviljelyn keskisatoa pienempi.
