Most of the misconceptions listed here were collected over the course of fifty years, mainly from practising farmers and students of agriculture. Naturally I am not suggesting that the readers of this journal are not clear about the incorrectness of most of these ideas, but some of these errors are the subject of serious debate even among specialists.
It is interesting to note that people working in other fields, who have never studied agricultural chemistry, are often more open to new knowledge than those who have. This can be attributed to both deficiencies in the teaching of agricultural chemistry and in the textbooks used, and to the fact that the basic concepts of agricultural chemistry have not been sufficiently clarified.
The vast majority of these deficiencies stem from the fact that neither the two-directional processes constantly taking place between different nutrient forms in the soil nor the quasi stationary balances consequently arising are taken into consideration.
