Section 3(f) of the Act defines as ``agriculture'' the ``production,
cultivation, growing, and harvesting'' of ``agricultural or
horticultural commodities,'' and employees employed in such operations
are engaged in agriculture. In general, within the meaning of the Act,
``agricultural or horticultural commodities'' refers to commodities
resulting from the application of agricultural or horticultural
techniques. Insofar as the term refers to products of the soil, it means
commodities that are planted and cultivated by man. Among such
commodities are the following: Grains, forage crops, fruits, vegetables,
nuts, sugar crops, fiber crops, tobacco, and nursery products. Thus,
employees engaged in growing wheat, corn, hay, onions, carrots, sugar
cane, seed, or any other agricultural or horticultural commodity are
engaged
in ``agriculture.'' In addition to such products of the soil, however,
the term includes domesticated animals and some of their products such
as milk, wool, eggs, and honey. The term does not include commodities
produced by industrial techniques, by exploitation of mineral wealth or
other natural resources, or by uncultivated natural growth. For example,
peat humus or peat moss is not an agricultural commodity. Wirtz v. Ti Ti
