Rapeseed is a crop very sensitive to inappropriate pH. The problem of too low pH also affects cereals. In these crops, it is also worth applying lime in an emergency if necessary. With low soil pH, nutrients are absorbed by plants much worse, so if liming is necessary on areas that have not been limed before sowing, it can be done during the vegetation of rapeseed in autumn. For this, Polish experts recommend quick-acting forms of carbonate lime or magnesium carbonate lime. Moreover, the recommended doses should be reduced compared to the potential dose applied before sowing or under the previous crop (by as much as 50-60%).
