objective

to do farming on a small area with huge production

Introduction

hydroponic is a process of farming in which the growing of plants in nutrient solutions with or without an inert medium (such as soil) to provide mechanical support in which a farmer does not need a big land or soil or a huge amount of fertilizer or huge amount of seed for production

in hydroponics essential part of process is PH , EC (electric cunductivity) , TDS if these three are properly maintaned we can do hydroponics easily

now 1ml = 1 ppm , so

there are some food or nutrients needed by plants for survive like nitrogen phosphorus potash magnesium calcium sulfur etc

Dose (fixed for palak)

  • N= 110ppm
  • P=60ppm
  • K=230ppm
  • Ca=90ppm
  • Mg=60ppm

how to use or provide it to plant

there are two type of nutrient compound

1 combination

2 single chelated (EDTA)

1 combination

nutrient which are bond to each other like

Potassium Nitrate

calcium nitrate

monoammonium phosphate

potasium sulphate

Magnesium Sulphate etc are combinations

2 single chelated (EDTA)

single chelated means the nutrient for ex nitrogen mineral is chelated or is given a coting or cell like structure so that it cannot make any bond with any other nutrient this method is expensive so the nutrients are also very expensive so they are use at an specific problum

method

how to give nutrient to the plant

so

We need N so we can give it by Ca(No3)2 75% and KNo3 25%by this we will get calcium and potash also so

In Ca(No3)2 we have 19%ca and No3 15%

so the formula is

we need 75 ppm so

100÷15=6.66

75 × 6.66=499mg/l and

499×19%=93ppmor mg

so now we have by this method

  • Ca(No3)2 = 500mg per liter
  • KNo3 =192mg per liter
  • NH3Po4=83mg per liter
  • K2So4=288mg per liter
  • MgSo4=631mg per liter

how to give it to plants in water

  • take the volume of container
  • Multiply the figer by the volume
  • We will get the x number in grams
  • First put half ingredients in the hydroponics and measure the ph
  • Ph is more than put phosphoruc acid 1 drop at a time and measur ph (it is the important step)
  • Now after 2 days see the condition of plant and put the rest

conclusion

we saw that the plants can be grown in water and it is very cost effective and less space is needed

half dosing given

Ca(No3)2 = 106 gm on 426 liter water

KNo3 = 41 gm on 426 liter water

NH3Po4 = 17.5 gm on 426 liter water

K2So4 = 48.5 gm on 426 liter water

MgSO4 = 134.5 gm on 426 liter water
