Weeds a   Weed Seed Yields at faville Grove 
Lrle Sowls 
Introduction 
During October, 1938, an attempt was made to measure the yield of 
weod seeds and study certain aspects of the weed problem as they affected

wildlife on the Paville Grove Area. 
The Job of determining yield was confined to those species of annual, 
non-noxious weeds that are most extensively eaten by geme birds. On this

area those were: yellow foxtail, green foxtail, lesser ragweed, barnyard

grass and smartweed. Our sampling technique proved too poor for smartweed

so no figures on smartweed yields are given. The amount of waste soybeans

on the ground after cutting the hay was also measured. 
The Faville Grove Wildlife Area Is made up of about 2,400 acres of 
general farm land. The soil is nearly all Clyde silt loam, though parts of

the area have either peat or alluvial soils. Most of the cultivated land
is 
slightly alkaline, as was proved by a number of soil samples. 
The season of 1938 was very wet and favored the growth of weeds. The 
fall was warm and frost came late, thus favoring fall plowing. Perhaps 
more fall plowing was done in 1935 on the Faville Grove area than ever before

in history. This plowing turned under the growth of food weeds that had 
sprung up, and birds soon moved off the area due to lack of feed. 
Procedure 
Randomised samples of one square yard each were taken from the fields 
sampled. To remove bias in sampling, a heavy stick one yard long was thrown

into the air and a sample was taken where this stick fell. A frame made of

slats was used to mark off the square yard and a scissors was used to harvest
