although increases were noticed from time to time. In
addition to water and temperature modifying effects of mulches that would differ
between soil textures and depend on the mulch source, increases in P concentrations
may result. As yield efficiency is still the primary factor determining income per hectare
for the producer, the decrease in yield that resulted from mulching under these
conditions, will still outweigh any positive contributions of mulches. It is therefore of
utmost importance to first adjust irrigation volumes to a mulch treatment before the
advantageous properties of mulching will be of value.
