Abstract The present study examined the biological characteristics and nutritional requirements of flax and outlined the most important agrochemical indicators of soil fertility. The study aimed to determine a range of soil parameters suitable for growing flax under conditions of increasing water content. The intention was to reach the full genetic potential and high yields of the given crop without causing damage to the soil. The solution provided for high returns on money spent to reach these parameters. The studies were conducted on dark-chestnut light soils with the presence of carbonate in the dry steppe region of Northern Kazakhstan. Soil parameters were 2.90 to 2.95% humus, 0.17% total nitrogen, 0.15% phosphorus, over 60 mg of mobile potassium per 100 g of soil, slightly alkaline pH at 8.08–8.1 and Ca2+ + Mg2+ at 20–22 mg-eq/100 g soil. Graphs depicting a quantitative relationship between soil fertility and flax productivity were addressed to determine the optimum level of mobile phosphorus in the soil, which could ensure the maximum yields of flax. An optimisation formula and fertilisation methods proposed in the present study to maximise yield may be relevant for other temperate steppe zones. Keywords Soil fertility . Fertiliser elements . Flax plant . Optimal parameters . Fertilisers . Yielding ability
Introduction Long-practised extensive agriculture led to soil degradation and, consequently, to decline of its productive capacity (Gomiero 2016). The 68th United Nations (UN) General Assembly declared 2015 the International Year of Soils (United Nations 2013). Soils constitute the foundation for agricultural development, essential ecosystem functions and food security and hence are key to sustaining life on Earth, the UN noted. This declaration recognises that proper land management results in sustainable agriculture and foodsecure economy. Given the aforementioned attitude, soil fertility improvement became an essential condition for sustainable agriculture in the country. Most crops are cultivated in steppe regions due to their gently sloping landscapes, temperate climate and optimal soil Responsible Editor: Haroun Chenchouni * Valentina G.

composition. Geographically, steppe zones are mainly located in the temperate latitudes of the Northern and Southern hemispheres. In Eurasia, steppes cover most of the territories of Russia, Kazakhstan, Mongolia and Ukraine. In the Americas, steppe zones dominate the USA and Argentina. Steppe soils are generally chestnut soils.
