The Russian invasion of Ukraine is depleting the soil of the important nutrients nitrogen, phosphorus and potassium, while the removal of these nutrients by crops exceeds their replenishment[1][2][3]. During the Soviet era, there was over-fertilization, leading to excess nutrients and pollution, but since independence in 1991, the situation has reversed: by 2021, 40-50% less phosphorus and 25% less potassium were being added than crops were taking, and organic matter content had fallen by almost 9%[3]. The war exacerbated the problem by disrupting fertilizer supplies, high prices, and damaged warehouses, forcing farmers to use less fertilizer[1][2][3]. A study by scientists from Great Britain, Ukraine and the Netherlands calls for an integrated nutrient management plan that minimizes wastage, reduces the consumption of synthetic fertilizers and includes precision fertilization, better use of manure, growing legumes such as beans, peas and lentils or cover crops[1][2][3]. Recommendations include mixed farming, local manure collection and redistribution systems, effective slow-release fertilizers and a national inventory of crop nutrient uptake for the 'smart fertilizer planner'[2][3]. Many measures require minimal investment and enable the transition to sustainable agriculture even during wartime, thereby reducing costs, maintaining productivity and minimizing environmental impacts[1][2]. The authors request financial support from the Ukrainian government and international partners for technique and manure processing[1][2].
