Precipitation use efficiency involves designing cropping systems to use precipitation effectively. The first strategy prevents runoff. Increasing soil health with better soil structure helps intense rainfalls infiltrate the soil rather than run off the field and not be captured by the crop. The second strategy reduces surface evaporation. Keeping residue on the soil surface through no-till reduces wasteful evaporation. The third strategy eliminates nonproductive uptake of soil water by eliminating weeds. Continuous no-till cropping keeps the soil covered, reduces weeds and increases infiltration. Thus, precipitation is used for growing crops for forage or grain rather than for nonproductive uses.
