Effect of years, fertilization and growing regions on the content and forms of potassium in soil

Popis výsledku v původním jazyce

The dynamics of potassium (K) in soil was investigated in long-term small-plot field trials at seven stations, where five combinations of fertilization were tested. The objective of the experiment was to estimate the effect of the weather conditions, type of growing region and increasing doses of fertilizers on the content of water soluble K (Sol-K), exchangeable K (Ex-K) and acid soluble K (Ac-K) in soils. The weather conditions had the strongest effect on the total variability of the Sol-K (34.9%), toa lesser extent on the variability of Ex-K (14.1%) and only negligibly on the Ac-K (0.3%). In the individual years of the experimental period, the content of water soluble and Ex-K was particularly affected, chiefly by the weather and due to different demands of crops for this nutrient (leguminous plants consume high amounts and cereals relatively low amounts of K). In fairly dry years (e.g. 1982), the level of potassium (Sol-K and Ex-K) in soil was higher than in years with precipitati
