In 1989 and 1990 two field trials were carried out each year in Oxford
County to determine the effects of kelp, molasses and 71B fertilizer solution
(1990 only) on soybean plant growth and seed yield in an aeration tillage
Results from two years of study indicate that the use of kelp and/or
molasses and/or 71B fertilizer solution as a seed and/or foliar treatment
in an aeration tillage system did not significantly affect the growth and
yield of soybeans.
(From Technology Transfer Report Summaries - A. Hayes, L. Cruickshank,
This 2 year study was carried out in Oxford county on 2 farm sites. The
objectives of the study are:
to determine the effect of kelp and/or molasses on main crop growth
and seed yield.
to prepare preliminary conclusions on the efficacy of kelp and/or molasses
as essential practices within the Aer-way system of low input crop production.
In 1990 additional treatments using the 71B fertilizer solution were
studied. Two farms with 2 sites/farm were used each year with four treatments
in year one and 6 treatments in year 2.
The parameters evaluated included soil texture, soil fertility, maximum
and minimum temperatures, precipitation, emergence, plant height, growth
stages, and yield.
The conclusions from the study were: (1) no significant difference in
emergence between treatments, (2) no significant difference in height of
soybeans 2 weeks after planting, (3) no significant difference in vegetative
or reproductive growth between treatments, (4) no significant difference
in yields amongst the treatments. Therefore the use of kelp and/or molasses
and/or 71B fertilizer solution as a seed or foliar treatment on a one year
application basis did not significantly affect growth and yield of soybeans
in an Aerway production system.
The researchers believe the study should continue for at least 3 years
to see if there is an accumulative affect of using kelp and/or molasses
over a period of time. Costs were not evaluated with this report but if
future research is to take place economics should be taken into account
for the added expense of foliar treatments and material cost.
Future Research: ( ) indicates reviewers suggestion for
priority, A - high, C - low.
(C) Continue research on additives over a number of years to see if there
is/is not a benefit and include an economic analysis.
