Plant Growth Rate Experiment

Post by wasiu0607 » Mon Jul 18, 2005 10:23 pm

HI. I am doing an experiment on which plants will grow faster with different types of fertilizer. I would like to know what kinds of fertilizers are there? What kind of fertilizer will make the plant grow at its fastest rate and why? Thank you. :D

you could compare brands or various concentrations of N,P,K
there are all sorts of fertilizers out there, I would suggest a trip to your local farm store.

We must device your plant life to 5 statement:(with ratio N:P:K)
1\seed: no fertizer (high concentration of ion make water move out from inside and it can't germinate)
2\After flowing(flower off): N>P,K. high Nitrogen for refresh tree after flowing and for new development.
3\Early Flowering: high Nitrogen will make flower off soon.now we need a lot of P and K, less N but still have.
4\Flower blooming: less N and P, more K
5\"sleeping" statement: less water or fertilizer if you want to see the next flowerseason
so the fertizer you need is N>P,K. (like N:P:K 30:10:10 or 60:10:10)
Hope it is useful for you
