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
