Aquaponic Plant Requirements
60 elements found in plants 16 considered essential Macro and Micro Elements Mobile or Immobile Elements
Essential Elements
Macro◦ - N, P, K, Ca, S, Mg
Micro◦ - Fe, Cl, Mn, B, Zn, Cu, Mo
Macro and Micro Nutrients
Carbon C Component of all organic compounds
Oxygen O Supplied by air and water
Hydrogen H Combines with oxygen to form water
Nitrogen N Part of chlorophyll, amino acids, proteins
Phosporus P Used in photosynthesis and almost all aspects of growth
Potassium K Activates enzymes, used in formation of sugar and starch
Calcium Ca Used in cell growth and division, part of cell wall
Magnesium Mg Part of chlorophyll, activates enzymes
Sulfur S Part of amino acids and proteins
Macronutrients-Needed in Large Amounts
Boron B Affects reproduction
Chlorine Cl Aids in root growth
Copper Cu Used in chlorophyll, activates enzymes
Iron Fe Used in photosynthesis
Manganese Mn Part of chlorophyll, activates enzymes
Sodium Na Used for water movement
Zinc Zn Part of enzymes, used in auxins
Molybdenum Mo Used in nitrogen fixation
Nickel Nl Liberates nitrogen
Cobalt Co Fixates nitrogen
Silicon Sl Makes tougher cell walls:Enhances heat and drought resistance.
Micronutrients are required in trace amounts
Mobile◦ Mg, P, K, Zn, N◦ Can be translocated, from older leaves to younger
leaves; deficiency symptoms appear on bottom of plant on older leaves
Immobile◦ Ca, Fe, S, B, Cu, Mn◦ Deficiency symptoms appear on upper plant,
young leaves first
Mobile and Immobile Elements
Mineralization
TDS – EC – CF – PPM Aquaponics vs. Hydroponics Remember pH Interactions
Nutrient Strength And Availability
TDS (Total Dissolved Solids)
62-779 (1200)
Ca 10-82 (150)
Mg 0.7-12.9 (50)
K 0.3-192 (150)
No3-N 0.4-82 (115)
PO4-P 0.4-15 (50)
SO4-S 0-23 (113)
Rakocy vs Resh-Aquaponics vs Hydroponics
Fe 0.03-4.3 (5.0)
Mn 0.01-0.19 (0.5)
Cu 0.01-0.11 (0.3)
Zn 0.11-0.8 (0.05)
B 0.01-0.23 (0.5)
Mo 0-0.17 (0.05)
Rakocy vs Resh-Aquaponics vs Hydroponics
Light Oxygen Supplements Temperature Adequate Plant Spacing Adequate Support And Protection Pruning And Training
Other Requirements
pH Interactions Add Base carefully and gradually so as not to burn fish
and plants Nitrate Regulation-Clean out net filter tank 1x week for
fruiting and 2 x week for high levels of nitrate – the more you clean the net filter tanks, the more active nitrification you will get. Cleaning these tanks regularly with non chlorinated water also reduces risk of pathogens in the water.
DON’T USE CHLORINATED WATER STRAIGHT FROM THE TAP. AGE TAPWATER 48 HOURS IN OPEN TANK BEFORE USE. CHLORAMINED TAPWATER REQUIRES RO FILTRATION AS DOES FLUORIDATED TAPWATER.
Favor the Plants if Necessary-they are the profit line.
Remember!
