Barley prefers mainly clayey and loamy-clayey soils that can drain easily. Regarding the chemical reaction of the soil, it prefers a pH between 6-7.5. Barley reacts positively to the addition of nitrogen. Nitrogen sufficiency in barley increases root system growth, tillering, foliage, shoot height and straw size. Excessive amounts of nitrogen are very conducive to foliar and shoot growth, cause sloping and crop ripening. The total amount of nitrogen required for barley is 7-17 kg per stremma, depending on the tendency of the variety to slope, the purpose of the crop (animal feed or malting), water sufficiency and the expected yield.

Of this amount, 50% is provided during basal fertilization in ammonia form, incorporated at sowing or just before, while the remaining 50% is provided during surface fertilization in ammonia, urate and nitrate form, with light irrigation or rainwater. In cases where the soil shows an acidic reaction, it is applied to the surface fertilization in the form of calcium ammonium nitrate.

Phosphorus sufficiency ensures good filling of the fruit and is associated with higher malt extract. At the same time, it stimulates early crop and acts synergistically with nitrogen for the benefit of the plant. The recommended doses depending on the phosphorus content of the soil usually range between 3-5 kg per stremma. Phosphorus is provided 100% in the basal fertilization. Potassium is essential especially in the early stages of plant growth. However, barley does not respond dramatically to the addition of potassium. In fields with deficiency, it is recommended to apply 5-8 kg per stremma during the basal fertilization, otherwise it is not necessary.
