This is a reflection of the widely adopted approach of varying only one or possibly two nutrients at a time in field experimentation. Without factorial designs involving a numbe

An obvious illustration of this principle is the common occurrence of Fe and Mn deficiency in plants despite the relatively high levels of Fe and Mn in many soils. For this reason, chemical soil tests have relied on measurement of extractable or “labile” fractions of elements

Pavel Hobza,Rudolf Zahradníkr of nutrient factors at varying levels, serious study of interactions is not possible. Until field research in soil fertility pays greater attention to the multifactor approach, there will be little prospect of verifying the large number of nutrient interactions previously studied under greenhouse or solution culture conditions.

hese improved pastures were less productive than others when productivity was assessed in terms of animal production. Recognizing the trace element requirements of grazing animals is essential when forage plants are grown primarily for animal feed.
