Stimulate early pasture growth this spring with ASN Cold Start™ - the only Viable fertiliser that works effectively at low soil temperatures. 

Stimulate early pasture growth this spring with ASN Cold Start™ - the only Viable fertiliser that works effectively at low soil temperatures. 

In an open letter to New Zealand agriculture Ian Ferguson shares his frustration about what he describes as a looming “nuclear moment” for New Zealand’s “green economy”.

Farmers can get a head-start on pasture and crop growth going into spring with a granular fertiliser that performs in cooler temperatures.

A recent article in Farmers Weekly (Striking the right Balance – May 29) highlighted a concerning move by the Government to cap synthetic nitrogen fertiliser use on pastoral farms.

Well because it has a fast-acting Nitrate (NO3-N) component, it works virtually immediately* on application whereas Urea, Ammonium Sulphate, and Ammo, (which is a blend of the first two) need time for its ALL ammonium (NH4-N) based Nitrogen to kick in. The cooler soil temperatures are, the slower that NH4-N will take as the bugs that break

A. The simple answer is DON’T!! Why?... All of the Nitrogen in these fertilisers is present in the slower acting Ammonium form which needs time to convert to faster-acting Nitrate N before the plant can pick it up. The bugs that convert it (Nitrification)® are very slow-acting at soil temperatures

For a start, it works in cool conditions when the alternatives languish!!  In 1995 AgResearch undertook field trials for BASF who imported ASN for the first time (1994). Those trials against Urea confirmed that:  ASN produced significantly more pasture dry matter than other N Forms (UREA)  The positive responses were maintained through to the
