Amino Acid Chelate Micronutrients Calcium Boron
Organic Fertilizer
Calcium has important physiological functions, and its effect on
apple quality is much greater than that of nitrogen, phosphorus and
potassium. Many fruit physiological disorders are closely related
to calcium deficiency, such as apple bitter disease, water heart
disease, fruit crack, and storage period. A large number of studies
have shown that maintaining high calcium content in fruit tissues
can maintain fruit firmness, reduce respiration rate, inhibit
ethylene production, and promote protein synthesis, thereby
prolonging fruit storage life and increasing fruit commodity value.
Calcium is present in plants in quite high quantities, localized in
the cell walls and on the outer surface of the plasma membrane,
calcium is indispensable for the cell division and stretching and
if absent, the radical growth is quickly inhibited. This element
intervenes in the activation of various enzymes and delays the
foliar senescence. Calcium, moreover, helps the germination, the
pollen formation and the radical development, it can also
neutralize some toxic organic acids produced by the plant while
breathing.
Boron is a basic microelement for plants as it stimulates their
vegetative development through the cells division, helping the
synthesis of the nucleic acids. Moreover, it develops an essential
role in the chlorophyll synthesis as well as in the production and
transport of sugars. In flowers biology, boron helps the
fecundation to increase the germinability of the pollen and the
activity of the pollen-tube, reduces the early drop and increase
the formation and quality of fruits.

2. Deficiency Calcium/Boron
The calcium deficiency breaks out with the reduction of the growth
of the vegetative apex and the youngest leaves, which can show also
necrosis and curls or deformations. The deficiency breaks out,
also, with the dissolution of the cell walls of fruits and back-up
organs, whose tissues become soft and marcescent. In some vegetal
species, the deficiency is very frequent and appears with necrotic
spots (ie.: bitter apple-scab) and apex rot (such as, tomato)
Calcium is almost motionless inside the vegetal tissues, very quick
growths of plants, excessive fertilizations with ammoniac nitrogen
and hard rains can enhance its deficiency.
Boron deficiency caused acute problems during flower fecundation
and increase the early drop of the small fruits. During growing
sprouts, it determines the shortening of the internodes and the
emission of less resistant and asymmetrical leaves. In the most
acute cases, in the fruit trees, it involves the bifurcation of the
sprout and the death of the terminal bud with consequent emission
of secondary sprouts, which make the plant look shrubbier, fruits
are damaged by evident necrosis, cracks and splits. In the tuber
cultivations, the deficiency breaks out with the gradual blackening
of tubers and tap-roots in their inner part.
