Only a relatively small amount of iron is needed, but this is critical for proper plant metabolism, affecting chlorophyll formation, photosynthesis and respiration in a plant.

How to use it

Use Seasol plus Iron as either a soil application or foliar spray. It is especially useful at important stages in plant development, such as germination, transplant, flowering, fruit-set or at any time when the plant is growing rapidly. For perennial tree and vine crops, a post-harvest application is also recommended. Seasol plus Iron is suitable for application by conventional spray equipment including air blast sprayers, multi row sprayers, boom sprays or fertigation equipment. For plants that are hard to wet, include a non-ionic wetting agent. Best practice requires that application be avoided under extreme weather conditions.

Foliar sprays For actively growing plants, vines and trees and increase plant stress tolerance 5-10L/ha
Boom sprayers & Under-tree sprinklers For all types of spray equipment, use the area normally covered by one tankful to detemine how much product to add 5-10L/ha
Drip or Micro-irrigation systems Use higher rates for lighter soils 5-10L/ha
Overhead sprinklers; Travelling or Pivot irrigators Use higher rates on lighter soil; lower rates on heavier soil (ie. The amount of concentrate needed per hectare of irrigated area for 10 mm of irrigation is 10L to 50L) 1L to 5L per mm of irrigation
Small volume applications 3-5 mL per litre in hand sprayers and knapsacks; 20mL to 50mL per 9L watering can
