but the real difficulties have come in the past two years. translation: when the covid pandemic started, we began i to have problems with shortages of raw materials. and that pushed up prices. we did not know how much it would cost to produce or how much the product would sell for, and then the war in ukraine, those difficulties just increased, especially with fertilisers. we started worrying if we d get enough for future crops. this is where anna stores her fertiliser, by far her biggest expense at the moment. last year, each of these bags cost £500. this year, when she plants her soya crop in october, this whole warehouse will be full of fertiliser, and of those prices have doubled. 85% of brazil s fertilisers come from abroad, and russia is an important partner.
