For instance, it would be useless to summer-fallow a field in order to kill an annual weed like the wild mustard which can be kept from spreading by any method that will prevent it from bearing seed.
In case there is any doubt about the complete eradication of the weed, corn planted in checkrows (see page 91) to allow cultivation both ways should follow the summer-fallow. Close watch should be kept of the field and if any weeds appear they can be removed by hoeing.
Effect of chemical and tillage summer-fallow upon water infiltration rates.
The use of dalapon and 2,4-D for maintaining summer-fallow land in weed free condition.
Colony sizes varied from a dozen plants in a residential flower bed to several 100,000 plants in a summer-fallowed
Soil from the surface 15 cm of a summer-fallowed field was collected in early August 2000 and 2001 from the WSU Dryland Research Station at Lind, WA.
Incremental soil sampler for use in summer-fallowed soils.
Insufficient seed zone water is a major limitation to the establishment of winter wheat (Triticum aestivum L.) on summer-fallowed
soils in areas of the Pacific Northwest (PNW) receiving < 300 mm (11.8 in) annual precipitation.
