Crop description

 Brassicas need micronutrients in very small quantities (they take up from several to several hundreds grams per hectare), however, the deficiency of any of them limits yields to the same degree as deficiency of a macronutrient. Also, an excessive amount of a micronutrient can be a problem when it occurs at too high a concentration in the soil or substrate, as it is toxic to plants. One should also remember that the regulation of the pH value of the soil is very important for the cultivation of these vegetables. The appropriate pH value promotes the uptake of macronutrients. An acidic pH causes a poorer uptake of macronutrients and a better uptake of micronutrients (except for molybdenum and magnesium which are taken up better with a higher pH than with an acidic one); it is the other way round with a higher pH - the optimal pH for cabbages is the range of 6.4-7.2, then the availability of macro- and micronutrients is at an appropriate level. In acidic soils with a low calcium content, the cabbage yields poorly and is very susceptible to clubroot.
