 Boron Information
Boron is a trace mineral found primarily in plant foods and necessary for plant growth.

 Boron for Minnesota Soils
Boron is not mobile in plants so deficiency symptoms will occur as stunting on the upper part of plants.
In Minnesota, a response to boron use might be expected on soils that have a sandy loam, loamy sand, or sand texture with a low organic matter content (figure 2).
Boron content will appear low when soil moisture supply is low because rotting and the release of boron from soil organic matter is reduced under these conditions.

 Boron Deficiency in Palms
Boron deficiency can be very transient in nature, often affecting a developing leaf primordium for a very short period of time (e.g., 1 to 2 days).
Boron deficiency is very widespread on palms growing in wet climates throughout the world, but can also occur in desert situations.
Because B deficiency is so transient in nature, the element is immobile within the palm (cannot move from one leaf to another), and deficiencies affect only leaf primordia developing within the bud area, leaf analysis is not particularly useful.

 UCCE Tulare County, Potassium and Boron Fertilization in Vineyards
Deficiency is likely to occur in cut areas, where the K rich surface soil was removed during land leveling, or on very sandy soils that have low native K fertility.
To correct a severe K deficiency in a small area of the vineyard, potassium sulfate at a rate of 2 pounds per vine is placed by hand in a small excavation made in the soil directly under the emitter.
Boron fertilization methods and rates should be carefully defined because of the small amounts needed for correction while avoiding over-application and possible toxicity.
