Field trial results

Broad acre crops - Potatoes

Plant Impact plc (AIM: PIM), which develops and markets ecologically friendly nutrition and crop protection products, announces first trial results from the Company's potato trial programme. Potatoes are the first broad acre crop to be targeted by Plant Impact.

Field trials were conducted in the UK, the Netherlands and Kenya on six varieties of potatoes by growers and distributors. The trials compared Plant Impact's products (CaT and PiNT) to standard fertilisation and competing products, with the following results:

·; Significant increase in the number of potatoes grown, ranging from 12.3% to 25.6%.

·; Substantial increase in yield from 6.7 to 9.4 metric tonnes per hectare.

·; Points increase on average of 26.1%. Potato traders in the Netherlands use a point system as an indicator of quality.

·; Storage quality of the potatoes also increased.

Following these encouraging results Plant Impact has extended its potato field trial programme targeted in key potato producing countries, most of them being in Europe. This programme includes: field trials (both research standard and commercial demonstration trials); working with key advisers and advisory bodies in each country; significant development and commercial assistance from key distributors and cooperatives; and aligned to a marketing campaign

Distributors and cooperatives have been involved in the initial trials and have seen the commercial advantages of using Plant Impact's CaT and PiNT technologies on potatoes. The worldwide production for potatoes covers 18.2 million hectares in 159 countries with an estimated market size of £280 million for the Companies products.

For 2010 the Company has planned 30 potato field trials, of which eight are to research standard, in eight countries, with yield, quality and storage results being available towards the end of the year. Five of these eight countries are amongst the top producing potato countries in the world in terms of yield.

Peter Blezard, CEO of Plant Impact, commented: "This is just one example of how we can extend the number of crops which use our products with significant commercial value to the grower, the distributor and to Plant Impact. We first tried CaT and PiNT products on potatoes last year and with these excellent field trial results we have developed a programme to extend the number of countries involved in our potato trial from three to eight."

About potato crop

The world potato sector is currently undergoing major changes. Until the early 1990s, most potatoes were grown and consumed in Europe, North America and countries of the former Soviet Union. Since then, there has been a dramatic increase in potato production and demand in Asia, Africa and Latin America, where output rose from less than 30 million tonnes in the early 1960s to more than 165 million tonnes in 2007. The Food and Agriculture Organisation (FAO) data show that in 2005, for the first time, the developing world's potato production exceeded that of the developed world. China is now the biggest potato producer, and almost a third of all potatoes are harvested in China and India.

The top 5 potato producing countries in terms of yield per hectare are Belgium, Germany, France, the Netherlands, the UK and the USA.
