The contents of these elements are tabulated for hair-grass meadow, hair-grass + foxtail meadow, & cabbage on bottomland of the river Moscow. The nutrient requirements of the sub-aerial part of the grasses were greatest at tillering & maturation, whereas the requirements of the roots were greatest at flowering. The requirements of the subaerial part of the roots of cabbage were greatest when the head was being formed.
