The
"Barrel Theory"
Yield is limited by the
nutrient in shortest supply.
 Many
growers cut back on secondary micronutrients if they feel they need to
save money. They think those minute traces will not affect yield "all
that much." With the help of a wooden barrel we can see how that cut
back in nutrients may affect the entire yield.
N, P and K may be applied to support a 175 bushel corn crop, but if
there is only enough zinc to grow 150 bushel of corn per acre your maximum
yield will be 150 bushels. Without the needed micronutrients, a crop
cannot reach its full potential. Another way to express this theory is the
fact that a chain is only as strong as its weakest link. Make Nulex Liquid
Zinc one of the strongest links in your micronutrient chain. |
