Relationship between Soil Physical Properties and Crop Production

  • J. Letey
Part of the Advances in Soil Science book series (SOIL, volume 1)


Having been labeled a soil physicist, I have received inquiries during my professional career concerning relationships between soil physical properties and plant growth as well as question on what constitutes good soil physical properties. Most inquiries could be put off by a recitation of generalities such as a loam soil having intermediate bulk density, good aggregation, good infiltration rate, and no impedance to drainage represented a soil with good physical conditions, and good production could be expected on such soil if chemical factors were not limiting. Generalities are not always acceptable as verified by the following three examples.


Bulk Density Root Growth Soil Erosion Soil Physical Property Affect Plant Growth
