The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...
Hoagland was able to show that various plant diseases are caused by a lack of trace elements and established their importance for plant nutrition, such as zinc in fruit trees. He pioneered research into the interactions between plant and soil by establishing soil pH and the importance of soil solution, temperature and light for plant growth and ...
For the 300 years following the arrival of Europeans, land was cleared, mostly for agriculture, at a rate that matched that of population growth. [7] During the 19th century, while the U.S. population tripled, the total area of cropland increased by over four times, from seventy-six million to three hundred nineteen million acres.
A class of harmful and difficult-to-remove pollutants lurk beneath Midwestern soil and in the region’s drinking water supply. ... that 45% of America’s tap water contained one or more of the ...
The project called for large-scale planting of trees across the Great Plains, stretching in a 100-mile wide zone from Canada to northern Texas, to protect the land from wind erosion. Native trees, such as red cedar and green ash, were planted along fence rows separating properties, and farmers were paid to plant and cultivate them. The project ...
It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate. The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water and wind erosion. The removal of vegetation increases the rate of surface ...
Arthur Rothstein's Farmer and Sons Walking in the Face of a Dust Storm, a Resettlement Administration photograph taken in Cimarron County, Oklahoma, in April 1936.
