Excerpt from Soil and Water Conservation Research in the Corn Belt States The movement of water through soil and rock into the zone of saturation and the effect of land manage ment practices on this movement are significant factors in hydrologic studies on agricultural land. Recorders are used to measure water-level fluctua tions. Tape over wheel in foreground is connected to a float. Changes in water elevation are permanently recorded on chart. Later, the data on the charts are transferred to punch cards for computer analysis. This type of recorder is extensively used in soil and water research. Lysimeters are isolated soil masses that have been instrumented to record weight changes and water per colation. The instruments enable scientists to make accurate assessments of moisture behavior in the soil. The Iysimeter shown is of an acre and 8 feet deep. It weighs 65 tons, yet can be weighed to a precision of 5 pounds. Scientists at Coshocton use lysimeters to study evapotranspiration, moisture use by crops, precipitation, water movement, and pollution. Level terraces are an effective means of controlling erosion (see sections 8 C), but what influence do they have on surface runoff and on ground water flow? Research conducted by scientists of the North Central Watershed Research Center near Council Bluffs, Iowa, has shown that the total water yield to streams is essentially unchanged. But much more of the water from the terraced area travels through the soil first. The values shown are 7-year averages for the research watersheds: rainfall Was about the same. Filtering more of the water through the soil means that higher quality water enters the streams and that damaging flooding is greatly reduced.

This publication describes a few examples of recent soil and water conservation research. The solution of soil and water conservation problems requires an intensive field experimental and investigational program supported by adequate laboratory and greenhouse research. From this research, practices are developed that can be applied to the land to conserve our resources.
