Perhaps you should try some spelling variations:
decreases soil » increases soil (Expand search), decreases local (Expand search), decreases in (Expand search)
soil decrease » oil decreases (Expand search), to decrease (Expand search), not decrease (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)

decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
akt object » art object (Expand search), art objects (Expand search), iot object (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreases soil decrease with decrease ) OR ( decrease of decrease akt object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreases soil decrease with decrease ) OR ( decrease of decrease akt object ))*.
