Mineral uptake by winter wheat (Trilicum aestivum L. cv. Martonvasari 8) was studied throughout the life cycle. Accumulation of macronutrients (i.e. total nitrogen, phosphorus, potassium, sodium, magnesium and calcium) and the water content of roots and shoots of plants grown in complete nutrient solution were higher than those of plants grown in two types of soils. The supply of macronutrients was in some cases limiting for soil‐grown plants as revealed by a comparison of available and accumulated amounts of these nutrients. Their supply was abundant, however, for solution‐grown plants. This led to a doubling of grain yield for the latter plants with a three fold increase in accumulation of dry matter and a five‐fold increase in fresh weight. The efficiency ratios of solution‐grown plants to soil‐grown plants were approximately 1 for N and Na, 0.5 for Mg and Ca, and 0.3 for P and K.
