The weather and rocketing input costs have impacted on farmers' confidence to invest in their business, at least in the short-term, according to a new survey from the NFU.

Today's report says the effect of adverse weather conditions combined with concerns over feed bills have dented farmer confidence in the short-term. Farmers remain relatively optimistic about the future of farming over the long-term but confidence in the red meat and pork sectors looks to remain weak.

NFU chief economist Phil Bicknell said the results came as "no surprise" given the exceptional year many farmers have experienced.

"The challenging year we've had makes it easy to forget that farming has been something of a success story in recent years, increasing its contribution to the economy, creating jobs, and seeing improvements in farm profitability, as well as underpinning one of the most successful British industries, food and drink," he said.

Results from the survey, now in its third year, show that last year's relatively optimistic outlook has faded, and only 22 per cent of farmers surveyed are confident about the year ahead, compared to nearly one in two twelve months ago. Some 42 per cent of farmers told the NFU that their farm businesses were in for a tougher year, up from 30 per cent in 2011.

"The drop in short term confidence is repeated across the sectors. For arable and horticulture, declines in crop output and quality, alongside difficult autumn planting conditions, have undoubtedly shaped farmer attitudes. The lowest levels of confidence, however, are seen in the livestock sector.

"Rising animal feed costs have been well-documented in recent months, and the confidence of pork, dairy and red meat producers has tumbled as costs have risen. While other sectors show confidence rising in the long-term, over the next five years this remains weak for red meat and pork. Tight supplies already characterise these markets and both sectors need greater confidence if we’re to see them able to respond.

"In keeping with results from previous NFU confidence surveys, the longer term outlook is generally more positive than the short term attitudes. Maintaining a degree of confidence is critical, given it shapes investment and production decisions across the industry. Results for the horticulture, poultry and arable sectors are notable in that they all show signs of increasing optimism when considering business prospects in the next five years."

Across the channel there is a similar picture. According to a recently published Copa-Cogeca confidence survey, the mood of French farmers has worsened, partly explained by high production costs and the poor economic situation. In Germany the positive mood among farmers can be attributed to an improved analysis of the future fiscal situation, while their views on current economic developments are less positive compared to the first quarter of 2012.

Mr Bicknell added: "Many farmers will be looking to harvests across the world throughout 2013 to improve commodity supplies and reduce some of the pressures on feed costs. Securing farmer confidence and long-term investment in this country will mean this industry can play its full part in providing the raw ingredients for the £80bn food and drink sector and continue helping the country on its way to economic recovery."
