New FertilizerpluS Compendium of Field Trials

Evidence of all the recent field trials in crops around the world that investigate the benefits of crop nutrition with our premium products is now available in the recently published Compendium of FertilizerpluS Field Trials.

Easy access to key crop nutrition information

There are major advantages of having all the research in one easy-to-access handbook. It is easy to search by crop or by country and to compare findings between trials and countries as well. The work of more than sixty field trials are summarised in the 76-page compendium. In each experiment an investigation is carried out comparing the benefits of applying Polysulphate, or PotashpluS with farmers’ usual practice, controls or other treatments.

Counting up the countries, crops and benefits

The country count in the Compendium is like an A to Z of nations, with 17 countries from Argentina to Vietnam represented. For crops, the list starts with banana and ends with wheat and has 20 more grain, root, fruit or other crops in between.

The breadth of the benefits of balanced fertilizer use shown in the field trials with FertilizerpluS products is impressive. The importance of the evidence speaks for itself: thirty field trials report up to 10% crop yield increase from using Polysulphate or a Polysulphate product such as PotashpluS, twenty show up to 20%, six up to 30%, and 10 describe up to 50% yield increase. At the top end, there are four trials reporting over 60% improvement. Crop quality benefits, so important particularly in fresh produce marketing, are also mentioned. The return on investment is also assessed in some of the trials.

Proof of gains through experimentation

The design and process of each of more than sixty field trial is concisely explained. For example, there is a handy summary of important trial details including when the trial took place, where, with what crop and with which soil type. Also, for each experiment the objective is clearly stated and there’s a useful summary of the trial’s treatment(s) and results.

Greater than the sum of its parts

Each of the experiments in our Compendium of FertilizerpluS Field Trials is useful in its own right. However, when gathered together – page after page, country after country and crop after crop – you get a catalogue of benefits to crops, farmers’ incomes and food supply systems giving the Compendium far-reaching significance for farmers and their advisors everywhere.

The Compendium is another important tool for the task of sharing the message of the importance of balanced and precise fertilizer strategies with FertilizerpluS and our Polysulphate products.
