We're trying to look for solutions regarding fertilizer burn. existing studies as related literature would be very helpful for us
Leaf scorch due to over fertilization, generally defined as fertilizer burn. It usually referring to excess nitrogen salts. It is due to the desiccation of plant tissues due to osmotic stress, creating a state of hypertonicity. The fertilizer burn roughly varies accordance with their salt index. Attached file may give some references, beside this, you may consult the paper of Andrews, Gail Gilick (1998),; Jones Susan (2008), Fertilizer Burn, American Orchid Society.
The possible solutions are: 1. Soaking the soils with water to flush out excess salts. 2. Apply only dilute or controlled released fertilizer products.
Burn can also occur with foliar nutrient sprays that are too concentrated or aggressive in composition.
Biuret toxicity-induced leaf tip burn is commonly observed ..
Dear Dr. Anoop,
I added iron fertilizer (1000 ppm) as foliar fertilizer to wheat crop, I did not observe toxicity or leaf tip burn.
In my opinion, using too much fertilizer can leaf tip burn, damage or even kill your plants.
I suggest after applying fertilizer, extra watering is required . Also dont let fertilizer contact with wet leaves.
