It isn't only the likes of shares, and robusta coffee futures, which have made a poor start to 2016.
Values of many fertilizers have too, with VTB Capital saying that prices have "had a tough start to the year".
Prices of benchmark nitrogen product urea, as measured in the key Baltic Sea export market, already down 5% this year to $220 a tonne, adding to a 26% slump in 2015.
Potash prices, as measured delivered to the Brazilian import market, are, at a seven-year low of $265 a tonne, down 4% so far in 2016, after also tumbling by 26% last year.
And a further decline may lie ahead, with broker Raymond James noting that "several traders are reportedly expecting prices to hit $250 a tonne".
The drop in potash prices, which have also fallen by 2% to $285 a tonne in the South East Asian import market, reflects "continued weak demand", Raymond James said.

According to Anda, the Brazilian fertilizer distribution industry group, the South American country's imports of fertilizers overall for the first 11 months of 2015 were, down 12.2% at 19.82m tonnes, with deliveries dropping 6.7% to 28.18m tonnes.
The continuing drop in prices has proved something of a vicious circle, in dissuading buyers from covering all but immediate needs, with delays too to a benchmark Chinese contract typically signed early in the calendar year.
"Most industry participants do not expect the Chinese contract to be signed until after the lunar new year, on February 8, due to high domestic supplies," Raymond James noted.
Credit Suisse flagged "adverse supply/demand dynamics across global potash markets".
The drop in urea values, meanwhile, has been attributed primarily to supply pressures, with Middle Eastern producers seen raising output, and economics for Chinese rivals improved by early-year weakness in the renminbi.
Lower energy prices are also a dent to urea price hopes – boosting production margins and so incentivising extra output from plants, which use the likes of natural gas or coal as a primary raw material.
However, values of phosphates – the third major fertilizer type – have held their ground so far, remaining at a two-year low of $295 a tonne in the Tampa, Florida export market, according to Credit Suisse.
This after an 18% drop last year.
For phosphates, renminbi weakness appears to have been insufficient to rescue margin prospects for Chinese producers, with China's Yuc unveiling plans to cut output by 1m tonnes.
On the demand side, Raymond James noted that US phosphates giant Mosaic has been "actively in the market purchasing barges which has provided some support".
