Initiation date:
1843
The Broadbalk experiment at Rothamsted Research in
It had its first winter-wheat crop sown in autumn
1843, and this crop has been sown and harvested on all, or part, of the field
every year since then. The experiment tests the effects of various combinations
of inorganic fertiliser (supplying the elements N, P, K, Na and Mg) and farmyard
manure on the yield of wheat: a control strip has received no fertiliser or
manure since 1843.

5. THE CULLARS
ROTATION
C.C. Mitchell, Department of
Alabama
email:
cmitchel@aces.edu
Tel 205-844-5489 FAX 205-844-3945
Initiation Date:1911
Stated Purpose:The Cullars Rotation was originally
established to determine the effect of soil fertilizer amendments (particularly
K) on yields of cotton, corn, small grains, and cowpeas in a 3-yr rotation with
and without winter legumes. In recent years, the test has been maintained as a
1) field laboratory for students and visitors studying crop nutrient
deficiencies, 2) source of soil and plant material for greenhouse and laboratory
research, and 3) site for continuous soil test calibration research.

Research Institute
Initiation date:
1914
Stated purpose: The experiment commenced in 1914
to demonstrate the effect of superphosphate and lime application on the stocking
rate of pastures.
