To say that soils in Poland are generally acidified is to say nothing. A total of 60-70 percent. soils in the country have an acidic reaction, with an approximately equal share of very acidic and slightly acidic soils. This situation has been changing in recent years, and the awareness of the need to maintain appropriate soil pH is increasing. However, let's see how much of the potential yield slips through our fingers precisely because of unregulated reaction. This also applies to winter cereals. In fact, only rye is more tolerant of slightly acidic reactions. Other winter cereals, primarily wheat and barley, are generally intolerant to unregulated reaction. Will they grow? Of course. Will they yield adequately? Not necessarily, even if they have enough other nutrients in the soil. In this context, let us pay attention to the issue of liming after rapeseed. Crop rotation in the rapeseed – cereal – rapeseed system (or cereal – rapeseed – cereal) is one of the most popular in Poland. What kind of soil for cereals does the rapeseed site have in terms of pH?
Liming after rapeseed will help nourish cereals with macroelements
Firstly, winter rapeseed leaves a large amount of harvest residues. What does this have to do with soil pH? Harvest residues affect the amount of organic matter in the soil, which in turn acts as a buffer that protects against a sudden drop in pH. Additionally, the rapeseed site gains in terms of biological richness. However, a beneficial reaction also occurs under the influence of liming. While rapeseed leaves have a large amount of harvest residue, they are better broken down thanks to the use of lime.
