Soil isnt just dirt. Soil is the surface layer of
the Earth that supports all life. In the Soil Science PAC,
students gain an
understanding
of the value of this life-giving substance. As students identify the
origins, characteristics, and physical properties of soil, they learn the
importance of maintaining its health and fertility.
Through hands-on
applications like soil testing, students check the pH of soil and learn to determine its
texture. Students also make recommendations for fertilizer applications as they discover
what conditions are necessary for growth to occur. After all, it takes an informed farmer
to produce a plentiful crop.
Students recognize regional differences in soil as well as identifying various
agricultural and nonagricultural uses of soil. Meanwhile, students assess their own
areas involvement through daily journal writings.
Once they have established a basis of knowledge, students identify alternative methods to
traditional soil-based growing techniques.
Students can test soil for secondary nutrients, determine slope, analyze soil samples, or
explore careers in the field of soil science.
