Seed Treatments


Manganese is an essential component of plant growth. The total amount of Manganese (Mn) in soils is typically around 0.25%, and is normally in the range of 0.02 to 1%.

Manganese is present in greater quantities than other trace elements, with the exception of iron. Its concentration typically exceeds that of macronutrients, such as Phosphorus and Sulphur, and often that of Nitrogen.

Consequently, where plant deficiencies occur, it is not because the soil is low in total Manganese, but because most of it is present in forms which are not available for plant uptake.

Manganese deficiency occurs in plants grown in alkaline soils, but is not common elsewhere. Toxicity occurs on very acid and poorly drained soils.

Exchangeable Manganese levels in the soil can fluctuate, depending on seasonal conditions. Temporary excessive levels may occur if the soil becomes water-logged. Manganese can be applied in to crops in several forms.  Foliar application of Manganese can be effective at critical stages of growth but this cannot take care of the early stages of deficiency when there is insufficient foliage or poor spraying conditions.

Treating the seed with New Manganese Solution (NMS) however, is the most effective way to protect the cereal crop from early deficiency problems.This unique seed treatment ensures Manganese is immediately available to the germinating seed.
