Synopsis
Excerpt from Field Records Relating to Subsoil Water
The rate of percolation through the Dakota sandstone can not, of course, be stated with any approach to accuracy, but it seems suffi cient to assume that it averages a yard or more a month. Still less can the 'rate of seepage through the cover be estimated accurately pending systematic observation, but manifestly it is less than the rate of evaporation (else exposed surfaces Would sweat or weep yet not very greatly less (else the wetness would not so rapidly and uniformly increase inward and downward); provision ally it may be estimated at an inch a month, and an inch a month is equivalent to 12inches a year, or enough to supplement the 15 inches of annual rainfall and supply the relatively abundant crops produced wherever the agricultural operations are conducted judiciously.

Paperback. Condition: New. Print on Demand. This book uncovers the relationship between agriculture and the capacity of soil to conserve and transport water for plant growth. This agricultural science book details how soil, subsoil, and underlying clays and shales interact with water. The author observed that moisture increases downward from the surface of the soil and inward from the surfaces exposed in cuttings, indicating that it is supplied from below and within. He infers that the water supply is not limited to the most recent rainfall or snowfall but instead comes from deep within the earth's crust through a process of capillary action. This subterranean water supply is what enables agriculture to thrive in areas with seemingly low rainfall. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781528117210_0
