Salts are absorbed by the roots.
commercial fertiliser is fertiliser made by a certain company.
Yes, using too much fertiliser in one application can lead to "fertiliser burn." This occurs when the excess salts in the fertiliser draw water out of plant roots, causing damage and browning of the leaves. It is important to follow recommended application rates to prevent this issue.
Buya lot of Chili seeds. Plant them in dirt, then water them and fertilise with red fertiliser. Then sell them. Fertilised chillies are worth more but if you can't get fertiliser don't worry they sell for $300 without fertiliser and $600 with fertiliser.
yes Further answer Not necessarily. Seeds don't take in fertiliser. But they take in water that may have fertiliser in it. But this fertiliser may not make them germinate faster.
depends entirely on the type and concentration of the fertiliser you are using
no
It depends what type of fertiliser. for example chemical. it will help seeds growth, but too much will burn the plant. But usually fertiliser does increase seeds growth. Just not too much of it. It is a fact that chemical fertiliser is less healthy than organic fertiliser. Hopt this helps :)
Plant food contains the 3 most needed substances in fertilizer: nitrogen usually supplied by nitrates, phosphorous usually supplied by phosphates, and potassium usually supplied by salts. Other trace compounds are also present.
