Tim’s Two Rules of Solubility• Rule #1:

if it ain’t soluble, it ain’t effective.

• Rule #2: if it was soluble, but you tank mixed with an incompatible tank mix partner, it ain’t soluble and it ain’t effective.

The Importance of SolubilityDifferent magnesium compounds were absorbed at

different rates by apple leaves (Fisher & Walker, 1955). After a 24 hour absorption period, leaf absorption of

magnesium was observed as follows:

Material Solubility % UptakeMagnesium Nitrate: 125 g / 100 ml 71%Magnesium Chloride: 54.3 g / 100 ml 32%Magnesium Sulfate: 25.5 g / 100 ml 8%Magnesium Phosphate: Only Slightly Soluble 4%

The Effects of Foliar Nutrition on Plant Disease

Direct Relationships withMineral Nutrition And Fungal Diseases

• Potassium deficiencies cause weaker, thinner cell walls and high sugar and amino acid concentrations in the leaf.• Calcium and boron deficiencies also causes a buildup of sugars and amino acids of both leaf and stem tissue.• Thinner, weaker cell walls "leak" nutrient laden fluids to the plant surface which creates a fertile environment that stimulates the germination of fungal spores on leaf and root surfaces.• Excessive nitrogen supplies bring about higher amounts of amino acid and amide concentrations.

• Plants have an Immune System which produces compounds that hinder disease attacks.• Boron plays a key role in the syntheses of defensive compounds.• Copper deficiencies hinder the production of these compounds, cause accumulation of soluble carbohydrates and reduced lignification.

Direct Relationships between Mineral Nutrition And Disease

“In order for a citrus tree to become infected with HLB, there has to be a large enough population of psyllids that live long enough to become infected, attack the tree, and overwhelm the defense (immune) system of the tree.”

Dr. Michael Rogers, University of Florida,

2008

What is the relationship between nutrition, production, and disease

resistance in citrus?

Nutrient levels that tend to be optimum for production are

optimum for disease resistance, as well...

EFFECTS OF FOLIAR UREA SPRAYS ON FLOWERING AND YIELDS OF VALENCIA

ORANGE TREES

“Urea applied between the dates of 25 Dec. and 11 Jan. increased flowers.

Winter urea sprays on the same plots for 4 consecutive years significantly

increased yields. Orange juice soluble solids per ha were increased when

compared to the control plots.”Gene Albrigo, IFAS, Lake Alfred, FL

KNO3 FOLIAR APPLICATION TO ‘SUNBURST' TANGERINE

“Trees receiving the KNO3 applications had over 30% more size 100 and larger fruit during the first spot picks in early

November of each year.

Trees receiving KNO3 applications averaged $5.00 more per tree during the first spot pick each

year in gross returns.”

Brian Boman, IFAS, Fort Pierce, FL

FOLIAR NUTRIENT SPRAYS INFLUENCE YIELD AND

SIZE OF 'VALENCIA' ORANGE “Over the 3 years, trees receiving the KNO3 or

MKP applications had 24-29% more fruit per tree, averaged 28% more boxes per tree, and

had 25% higher total pound solids per tree than the control treatment. “
