Anyone who has not yet bought fertilizers for corn or who increases the area at the last moment has a difficult task, as popular solutions such as urea and ammonium phosphate are currently very expensive. Prof. Tadeusz Michalski recommends primarily natural fertilizers – manure or slurry – for pre-seeding fertilization for corn. When it comes to mineral fertilizers, the president of the Polish Association of Corn Producers recommends superphosphate and divided nitrogen doses, not necessarily in the form of urea. Corn is the second most important crop grown on Polish fields, occupying nearly 2 million hectares nationwide last year. The very poor profitability of grain production at that time, resulting from high humidity and low purchase prices, meant that cost accounting became even more important than before. We asked the president of the Polish Association of Corn Producers, Prof. Tadeusz Michalski, what to focus on if we do not yet have fertilizers for corn, and urea and ...

Varieties with flint grain type are more tolerant of lower temperatures (seeding is possible at 5–6°C). Varieties with dent (dentate) grain type require warmer conditions, i.e., soil temperature between 8–12°C. For late sowing, it is recommended to choose varieties with a lower FAO. The start of corn sowing in Poland is strongly dependent on weather and soil conditions, which in recent years have been highly variable. Although the agrotechnical calendar indicates approximate dates, in practice, soil temperature, its moisture, and the risk of frost determine the optimal time to begin field work. Of course, the most important parameter determining the start of corn sowing is the soil temperature at the sowing depth, i.e., at a depth of 5-7 cm. It is assumed that the safe threshold is about 8–10°C in terms of the daily average. This to some extent guarantees uniform and rapid germination and limits the risk of seedling damage by cold. Do we already have such conditions? Rarely. Corn ...
