"In the current weak market environment, which is further intensified by the continuing Chinese import bans on the standard potassium chloride product, adjusting production is a difficult decision, but the right one," K+S executive Alexa Hergenroether said in a statement on Monday.
The group's potash output will be reduced by up to 300,000 tonnes by the end of the year, holding back core earnings, or earnings before interest, taxes, depreciation and amortisation (EBITDA), by as much as 80 million euros (70.7 million pounds), the company said.
It had previously forecast 2019 EBITDA of 730-830 million euros, targeting the sale of 6.9-7.1 million tonnes of potash for the year.
Larger Canadian rival Nutrien earlier this month flagged a $100-$150 million reduction in potash EBITDA as a result of cutting output by about 700,000 tonnes.
Russian potash producer Uralkali last week followed up with plans to reduce output by 350,000-500,000 tonnes.
