Hydroponics is cultivation of plants without stain . All the nutrient require for the flora are supplied through a nutritious solution . Nutrients like atomic number 8 , carbon paper and H are absorbed by the plant from air and water . The primary macronutrients are atomic number 7 , phosphoric and K . Secondary macronutrients are calcium , magnesium and sulfur . The essential micronutrient are atomic number 26 , manganese , boron , molybdenum , zinc , copper and chlorine . dissimilar combination of nutrient are used in prepare various nutrient solution bet on the requirements of a fussy plant . The pH story of the nutritious solution is significant for hefty growth of the plant . Majority of the plants develop well in slenderly acid conditions in the pH range of 5.5 to 6.5 . The nutrient solution in aquiculture crop for 10 to 15 days .

Nitrogen

Nitrogen is an important macronutrient ask for the overall development of the plant . surplus supply of N leads to weak growth and holdup flowering . unequal supply of nitrogen outcome in yellowing of leave of absence and frail maturation . Nitrogen is parcel out in the form of ammonium ion phosphate , potassium nitrate and atomic number 20 nitrate in hydroponic systems .

Phosphorus

Phosphorus is required by the plant in photosynthesis , growth of antecedent , flowers and seed . inadequacy of morning star may lead to discolouration of leaves and scrubby development . Supplying excess amount of phosphoric case deficiency of micronutrient like iron and zinc . This primary macronutrient is supplied to the plants through ammonium phosphate and potassium phosphate .

Potassium

atomic number 19 plays a major role in works increment , specially in the evolution of the fruits . It helps in development of roots and in synthesis of chlorophyl , amylum and sugar . atomic number 19 regulates stomata openings thereby help oneself the plant in make ideal use of air and water . Potassium deficiency results in yellow of parting and blossom and fruit fall . Overdose of potassium fall supply of magnesium and calcium . atomic number 19 inorganic phosphate and atomic number 19 nitrate are near sources of atomic number 19 .

Calcium

Calcium is essential for the growth of plant life cell and roots . atomic number 20 also ease preoccupancy of potassium . It also aid avert redundant nutrients in the soil . deficient supply of calcium result in kink and stunted outgrowth of leave and shoots . supererogatory calcium results in stunted growth . It is supply in the form of calcium nitrate .

Magnesium

Magnesium is a constituent of chlorophyll molecules and plays an significant role in light absorption . It also helps in distribution of phosphorus throughout the plant . short provision of atomic number 12 give rise to curl and discolored leave . Though higher concentrations of magnesium does not affect the works , if coupled with imbalanced quantity of calcium and atomic number 19 , the combining stunts flora growth . It is dole out in the form of atomic number 12 sulphate .

Sulfur

Sulfur increases the effectualness of morning star . It also helps in the production of energy . Deficiency direct to yellow of leave of absence , whereas excess provision stimulate untimely shedding of leaf . Hydroponic plants are administered with this nutrient in the form of magnesium sulfate .
