Chloride
Nutrient Benefits
Antagonism
- High Cl levels can reduce the availability
- of Phosphorus
- Chloride uptake is reduced when high N-NO3-, SO4-, B or Mo
Stimulation
- Chlorides stimulate mono and divalent cations ( K+, Zn2+, …)
Functions
- Cation balance, transport
- Diminishes effect of fungal infections
- May compete with nitrate uptake, promoting use of ammonium, which may factor in its role in disease suppression
- Works in tandem with K for the proper function of stomatal openings, controlling internal water balance
- Photosynthesis specifically the control of gas/water exchange
Deficiency Symptoms
- Wilting
- Restricted, highly branched root system
- Leaf mottling
- Leaflet blade tip wilting with chlorosis
- In cabbage, absence of cabbage odour
Factors Affecting Availability
- Areas where rainfall is high and internal soil drainage is good, Cl can be leached from the soil
- Soils where potash fertilizer is not regularly applied
- Inland regions are generally less in chloride disposition versus coastal regions
- When there is an excess of N, S, B, and/or Mo
Sensitive Crops
- Alfalfa, broccoli, brussel sprouts, cabbage, cauliflower, lettuce, oil palm, potato, small grains, beets, tomatoes, cereals, canola, canary seed
