The number of seasonal workers coming to Britain's farms from the EU has dropped 17% and the outlook for the next two seasons is 'in jeopardy', according to a new report.
The latest report from the NFU's Vision for the Future of Farming said the industry had 'growing concerns'.
It urged the government to create an immigration policy to offer appropriate visas for recruiting seasonal labour overseas.
"It is crucial that the government addresses these concerns immediately to ensure that farming has access to a competent and reliable workforce," said NFU president Meurig Raymond.
"A solution, such as a suite of visa or permit schemes is urgently needed to avoid losing a critical number of workers that could jeopardise future harvests and food production."
A recent industry survey by British Summer Fruits showed that prices could soar by 50% if the UK cannot gain access to EU workers after Brexit.
'Urgent clarity'
It takes time for businesses to recruit and for seasonal work they typically plan nine months in advance.
The supply of seasonal workers for the 2018 and 2019 seasons is 'already in danger', the report said.
It also raised the issue of a permanent workforce and said the industry had 'serious concerns' about it.
The NFU said they were calling on the government to provide 'urgent clarity' on the status of EU nationals living and working in the UK.
"The forthcoming Immigration Bill must recognise the importance of migration for certain sectors and Government must recognise the strategic importance of the UK farming industry as the bedrock of the UK’s food and drink industry, worth £109 billion to the economy," Mr Raymond said.
"The NFU would like to see the Government consult extensively with the farming industry on this issue to ensure a solution is reached and as soon as possible."
Prime Minister Theresa May unveiled proposals for EU nationals who have lived in the UK for five years by a specific cut-off date to be given the chance to take up 'UK settled status'.
