Cabbage Fertility Experiment

To determine how balanced nutrition programs
increase the productivity of crops and vegetables,
AGGRAND scientists compared petrochemical
fertilizers with AGGRAND fertilizers. In one
AGGRAND experiment conducted in the AMSOIL
Growth Center, cabbage fertilized with AGGRAND
produced larger, more flavorful heads compared
to those produced by Miracle Gro®.

There were several AGGRAND treatments which
were compared to Miracle Gro®. Two of the
AGGRAND treatments were grown on soilless
media, and the Miracle Gro® treatment was grown
on media with soil to see if AGGRAND could outproduce
Miracle Gro® without relying on the extra
nutritional value of the soil. One AGGRAND treatment
was applied to the media every two weeks, and
the other AGGRAND treatment was applied in the
same way with an additional foliar treatment
applied before heading and a banded treatment
applied at transplanting.
Miracle Gro® was applied to the media every two
weeks just like the AGGRAND treatments. Three
ounces of the newly formulated AGGRAND 4-3-3
Natural Fertilizer were mixed with one gallon of
water to be applied to the media and to the leaves.
For the Miracle Gro® treatments, one teaspoon of fertilizer
was mixed with one gallon of water and
applied to the media as stated in the directions.
For the banded treatment at planting, two ounces
of the new 4-3-3, two ounces of AGGRAND 0-12-0
Liquid Bonemeal and one ounce of the newly formulated
AGGRAND 0-0-8 Natural Kelp and Sulfate
of Potash were mixed in one quart of water. This
mixture was placed into a trench below and to the
side of the roots. The additional AGGRAND treatment (root feeding plus foliar plus band) would
tell the scientists whether the additional products and treatments (AGGRAND Plus) were effective in
obtaining even higher yields than the single product and treatment (AGGRAND). The AGGRAND and
AGGRAND Plus treatments both produced highly significant increases in mean head weights over the
Miracle Gro® treatment (see bar graph). The AGGRAND treatment produced a 308% increase in mean head
weight and the AGGRAND Plus treatment produced a 379% increase in mean head weight. The AGGRAND
Plus treatment also produced an increase of 71% in mean head weight over the AGGRAND treatment. The
take-home message tells us that AGGRAND is more effective than Miracle Gro® even when the AGGRAND
plants are grown in soilless media. In addition, the use of banded and foliar applications with a combination
of AGGRAND products are effective in obtaining even higher yields than soil applications of one AGGRAND
product alone.
