Effects of long-term mineral fertilization on silage maize monoculture yield, phosphorus uptake and its dynamic in soil
Original language description
A long-term continuous silage maize monoculture experiment (1993-2019) was conducted in the Czech Republic to assess the effects of different mineral fertilizers on P balance. An unfertilized control (C) was compared with i) ammonium sulfate (AS), ii) urea ammonium nitrate (UAN), iii) UAN + triple superphosphate and potassium chloride (UAN+PK), and iv) UAN + triple superphosphate and magnesium sulfate (UAN+PMg), respectively. Maize P uptake, content, BY, AE, SYI, and P utilization over the 27 years increased in the order of UAN+PK - UAN+PMg - UAN - AS - C treatments. AS and UAN only fertilizing caused a more negative P balance (on average -621 kg P ha-1 27 yrs-1) as compared to the control (-483 kg P ha-1 27 yrs-1). Generally, almost all indices show that N only fertilizing (AS and UAN) significantly decreases the bioavailable and even the stable inorganic P forms and has a negative influence on overall P-sustainability. The effect of this fertilizing system was even more negative than control.
