 Boron
Boron nitride is a material in which the extra electron of nitrogen (with respect to carbon) in some ways compensates for boron's deficiency of an electron.
Boron is an essential plant micronutrient, notably playing a role in plant fertilization and in the building of cell wall structures; as such, borates are used in agriculture.
Boron compounds are being investigated for use in a broad range of applications, including as components in sugar-permeable membranes, carbohydrate sensors and bioconjugates.

 Boron Information
Boron is a trace mineral found primarily in plant foods and necessary for plant growth.
Although the biochemical mechanism of boron is not yet known, it does increase steroid hormones such as the sex hormone and vitamin D. Boron plays a role in cell membrane functions that influence response to hormone action, trans-membrane signaling, and trans-membrane movement of regulatory ions.
Since boron seems to play a role in bone metabolism, particularly with vitamin D and estrogen, postmenopausal women would benefit from adequate intakes of boron to aid in the prevention of osteoporosis.

Boron deficiency results in decreased blood levels of ionized calcium and calcitonin, elevated levels of total calcium and urinary excretion of calcium.
Boron and magnesium metabolism might be related, since a combined deficiency of these two minerals exacerbates the osteo condition, suppresses bone anabolism, and results in decreased magnesium concentrations in bones.

 You may need the Boron in your wine By Harvey E. Finkel, M.D
Boron is, in fact element number 5 in the periodic table, mostly mined in California, of considerable industrial importance, a component of the cleaning agent 20 Mule Team Borax, the sponsor during radio days of pre-Ronald Reagan Death Valley Days.
Because the range between deficiency and excess is narrow, as appears to be the case in humans, boron toxicity may be brought about by uneven application of borax to prevent or counteract boron deficiency.
Boron is protective, apparently by preventing inappropriate activation of cells (T-suppresser and T-helper) important in autoimmune chain reactions.

 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 is a highly mobile element that rapidly leaches from the soil.
However, because boron leaches very rapidly from the root zone, there is little correlation between boron levels shown in the test and the amount that is actually available to the plant during the growing season.
Boron may be applied in fertilizer, in preplant herbicides alone, or with leafspot sprays.

 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.
