water for farming

[macsd]

I'm no farming expert but what i suppose your use for the question is for plants or irrigation. Well , any source of water whether from balon, river, stream , city supplied even rain has their own individual contents/minerals yet plants still grow. It's the absence of water that will hinder the life of a plant. Now if your into a particular use of farming like hydroponic or the like, then the water should be something you have to threat to specific level.

share ko na lang ito sir. napansin ko lang sa mga farm lots namin.

'yung patubig namin eh galing rin sa poso or pumped from underground.
palay ang tanim namin. napansin ko lang na may taon na iba naman ang nakatanim.
ang sabi ng mga farmers namin: nawawala daw ang sustansiya ng lupa kaya minsan
kailangan rin taniman ng iba. para nga rin daw tao 'yan na minsan eh pakakainin mo
ng ibang klase ng ulam.

hindi naman ako eksperto sa mga ganyan, but i think it really works.
wala naman kasi akong alam na inihahalo nila sa tubig except the fertilizers and/or insecticides.
