MINOR ELEMENTS IN HYDROPONIC GARDENING

MINOR ELEMENTS

This minor elements section discusses elements typically found in water and often added as additions in nutrient solutions. These values will normally be very low. Consider the accumulated concentration of these elements in the media, fertilizer and water.

 

BORON biochemical functions are yet uncertain, but evidence suggests it is involved in the synthesis of one of the bases for nucleic acid (RNA uracil) formation. It may also be involved in some cellular activities such as division, differentiation, maturation and respiration. It is associated with pollen germination. Plants deficient in boron exhibit brittle abnormal growth at shoot
tips and one of the earliest symptoms is failure of root tips to elongate normally. Toxicity will cause yellowing before leaves die and prematurely fall off.

 

 

COPPER is a constituent of many enzymes and proteins. Assists in carbohydrate metabolism, nitrogen fixation and in the process of oxygen reduction.

Symptoms of deficiency are a reduced or stunted growth with a distortion of the younger leaves and growth tip dieback. Copper is required in very small amounts and readily becomes toxic in solution culture if not carefully controlled. Excess values will induce iron deficiency. Root growth will be suppressed.

 

 

IRON is an important component of plant enzyme systems for electron transport to carry electrons during photosynthesis and terminal respiration. It is a catalyst for chlorophyll production and is required for nitrate and sulfate reduction and assimilation. Interveinal chlorosis of younger leaves is the typical symptom of deficiency. Excess accumulation is rare but could cause bronzing or tiny brown spots on leaf surface.

 

 

MANGANESE is involved in the oxidation reduction process in the photosynthetic electron transport system. Biochemical research shows that this element plays a structural role in the chloroplast membrane system, and also activates numerous enzymes. Interveinal chlorosis of younger laves, necrotic lesions and leaf shedding are typical symptom of this deficiency. High levels can cause uneven distribution of chlorophyll resulting in blotchy appearance.

 

 

ZINC plays a role in the same enzyme functions as manganese and magnesium. More than eighty enzymes contain tightly bound zinc essential for their function. Zinc participates in chlorophyll formation and helps prevent chlorophyll destruction. Carbonic anhydrase has been found to be specifically activated by zinc. Deficiencies appear as chlorosis in the interveinal areas of new leaves producing a banding appearance. Branch terminals of fruit will die back in severe cases. Excess will cause sensitive plants to become chlorotic.

COBALT is essential to many beneficial bacteria that are involved in nitrogen fixation of legumes. It is a component of vitamin b12 which is essential to most animals and possibly in plants. Reports suggest that it may be involved with enzymes needed to form aromatic compounds. Otherwise it is not understood fully as to its benefit to plant growth, but it is considered essential to some animal
health issues.

 

 

MOLYBDENUM is a component of two major enzyme systems involved in the nitrate reductase, this is the process of conversion of nitrate to ammonium. Moly deficiencies frequently resemble nitrogen, with older leaves chlorotic with rolled margins and stunted growth. Excess moly usually does not effect the plant, however the consumption of high levels by grazing animals can pose
problems.
