Vergleich verschiedener Bordünger bei Ackerbohnen

Summary translation

The impact of two different boron fertilizers (borate and boric acid) on field beans were examined in field experiments over two years at two experimental sites in Bavaria and over one year at one site in Lower Saxony. In one environment, the trial could not be valued due to insufficient statistical values. With borate fertilized beans yielded higher in two of the four environments in comparison to boric acid and unfertilized control. The boron availability in soil was low in one of these two environments (class ‘A’), but not in the other one. The other nutrients in borate did most probably not affect the yield due to very less quantity (e.g., less than one kg S/ha). Hence, lack of boron may limit yield in organic farming.
