What reading level is The Relation of Plant Succession to Crop Production a Contribution to Crop Ecol book?
To quickly assess the difficulty of the text, read a short excerpt:
Yet the maximum production of wheat centers in the region where the rainfall is only six-tenths or less of the evaporation called for. An attempt to cor- relate crop centers and vegetation centers considering only the climatic and edaphic factors would present many strange anomalies. These explanations alone would not support the facts of the dis- tribution. It is necessary to go outside the field of physiology to discover the basis of crop distribution.
The fundamental difference in the occurr...ence of plants belong- ing to the natural vegetation and the crop plants lies in culture. In the vegetation invaders from another center are frequently re- stricted to one habitat, often a poor one. Arbor vitae in central Ohio is confined to the rock terraces of stream gorges and to bogs. The white pine and the scrub pine meet on rock cliffs east of the glacial boundary. On Lake Michigan sand dunes the jack Pine and the cactus meet. Yucca extends northward along the sand plains of the Atlantic seaboard.
