Soil nutrient contents in a long-term field experiment following the suspension of phosphorus and potassium fertilisation
Original language description
The effect of mineral, organic (manure or straw+intercrop) and combined fertilization on the development of soil nutrients contents in time and their mutual ratios was evaluated in a long-term field trial IOSDV (established in 1984 at two sites) differing in the soil-climatic conditions. Three cropping cycles 2016-18, 2019-21 and 2022-24 were studied in the following crop rotation: winter wheat – winter barley – root crop (sugar beet at Ivanovice na Hané, potatoes at Lukavec). Potassium and phosphorus in mineral fertilizers have not been applied since the year 2020 due to their high content found in soils after dry years with low yields. Consequently, their content decreased, most in the third rotation, both by the Mehlich 3 method and especially the exchange fraction extractable with NH4-acetate (Ivanovice: P 5–14%, 32–40% and K up to 12%, 9–20% determined by Mehlich 3 and NH4-acetate, respectively; Lukavec: Mehlich 3 - P increase: 5–16 %, K decrease: 0–8 %; NH4- acetate decrease - P: 10–13 %, K 8–23 %). The mutual ratio of nutrients equivalents K:Mg:Ca was lower than required values 1:2-3:10-15 at both sites and all studied treatments, however a slight increase was observed during the studied period, above all in system with only mineral fertilization (Ivanovice: K:Mg:Ca from 1:1.2:5.6 to 1:1.4:6.8, Lukavec: from 1:1.0:7.7 to 1:1.0:9.6). A correctly balanced ratio of nutrients in the soil is important for maintaining soil fertility.
