  Meadows have been proposed as alternatives for fields with a purely
equational axiomatization. At the basis of meadows lies the decision to make
the multiplicative inverse operation total by imposing that the multiplicative
inverse of zero is zero. Thus, the multiplicative inverse operation of a meadow
is an involution. In this paper, we study `non-involutive meadows', i.e.\
variants of meadows in which the multiplicative inverse of zero is not zero,
and pay special attention to non-involutive meadows in which the multiplicative
inverse of zero is one.
