The Phosphate and Potash Starvation of Forest Seedlings as a Result of the Shallow Application of Organic Matter
Shallow applications of organic matter to nursery soil have always been considered objectionable because such a practice leads to the production of planting stock with superficial root systems consisting entirely of laterals. The present study has indicated even more serious detrimental effects of top dressings. The arresting of the downward extension of the root systems upsets the balance of nutrition as the seedlings are deprived of important nutrients, mainly phosphate and potash, at present at greater depth. Alternate disking and plowing, or rototilling are recommended to prevent this condition.
