Päätehakkuun ja maanmuokkauksen vaikutus metsän vesi- ja ravinnevirtoihin
Metsä pidättää tehokkaasti siihen laskeuman mukana tulevia ravinteita. Ravinteiden kier to metsässä on yleensä niin suljettua, että niiden huuhtoutuminen laskeumaan verrattuna on vähäistä.

متن کاملMorphophysiological traits and atrazine sensitivity in Chenopodium album L.
BACKGROUND A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS Atrazine (2 kg ha(-1)) killed S and VC shoot biomass 15 days after treatment (DAT), but R was only suppressed by 42% and survived 8 kg ha(-1). Atrazine at 2 kg ha(-1) only inhibited VC height by 60% as agai...

متن کاملGermination behaviour of seeds from herbicide treated plants of Chenopodium album L.
The carry-over effect of sub-lethal herbicides was investigated on the germination of seeds collected from surviving Chenopodium album plants, which had received 1/8, 1/8 twice, 1/8 three times, 1/4, 1/2, 1/1 doses of either pre-emergence ioxynil or post-emergence bentazone in a previous onion (Allium cepa) crop. Seeds were also collected from surviving C. album plants, which had received 1/4, ...
