Paperback. Condizione: New. Print on Demand. This book centers around the discovery that many unproductive soils are not lacking in nutrients, but contain substances that hinder plant growth. The author, a leading soil scientist, shares compelling evidence of these findings through experiments with wheat and oat seedlings and extracts from unproductive soils. He demonstrates that these toxic substances can be removed using simple treatments like filtration through carbon black, indicating that they are organic in nature. This book highlights the crucial role of examining the biological and chemical properties of soil to enhance crop yields. Understanding the impact of plant excretions on soil health and how they can create unfavorable conditions for subsequent plant growth adds a new dimension to the study of soil fertility. The author's findings have significant implications for sustainable farming practices and provide a foundation for further research in soil science.
