Requirement for magnesium fertilization in Finland

Abstract: More magnesium, on average, is removed annually from agricultural soils in Finland in yields (10 kg/ha) and through leaching (20kg/ha) than is replaced as fertilizers (4 kg/ha), manure (7 kg/ha) and as wet or dry depositions from the atmosphere (1 kg/ha). The amount of magnesium which is applied in assosiation with liming agents (at the most 25 kg/ha) has a decisie effect on the magnesium balance of the soils, although liming itself reduces those magnesium reserves of the soil which are extractable in neutral … Show more

“…Fields get Mg via deposition [15], but possible is that losses per air can be remarkable, too. Association parameters calculated by 3-y means values can make bias, but raw fertilization figures make their own bias, because duration of action is longer than one year.…”
