The Science

The Science behind Tow and Fert

An OVERVIEW of Foliar applied fertiliser science.

The Tow and Fert system hasn’t redeveloped any agronomic benefit that is new or breakthrough; what it has done is enabled farmers and contractors to access this benefit easily with a very quick return on investment.

The three areas that the Tow and Fert has opened up to farmers and contractors are;

  1. The ability to dissolve any nitrogen based product, but primarily urea to create a plant available liquid
  2. The ability to mix, suspend and apply micro-fine particulate fertiliser.
  3. The ability to reduce thier farm inputs whilst growing the same amount of grass.

Research from around the world, undertaken by third parties have proven these three key benefits to assisting in reduced fertiliser use which has obvious financial and environment benefits – all whilst sustaining DM yield and grass nutrient quality.

In summary, the key reasons for these benefits are;

– Foliar applied urea is more plant available
– Fine particulates are more available in the soil due to surface area

One of our Farmers, Allan Marx, was recently profiled in the Dairy Exporter Magazine on his use of foliar applied fertiliser.
