Fertilizer Salt Burn
List of files and visuals associated with this text.
Fertilizer salt burn can occur when excess chloride salts
come in contact with the developing root system of young
plants. This problem is more likely to occur when banding
fertilizer materials containing nitrogen and/or potassium
too close to the seed. Broadcasting the fertilizer is
less likely to cause burn, but injury can still occur on
soils that have a marginal salinity problem, especially
coupled with dry weather near planting time. The
characteristic symptoms are marginal necrosis of leaves,
plants taking on a bluish appearance and/or sudden
wilting of the plant. (Vis. 1) Unless this salt
concentration is reduced by rainfall or irrigation,
seedlings often die or remain extremely stunted.
