1.1. INTRODUCTION Plastic covering, either framed or floating, is
now used worldwide to protect crops from unfavorable growing
conditions, such as severe weather and insects and birds. Protected
cultivation in the broad sense, including mulching, has been widely
spread by the innovation of plastic films. Paper, straw, and glass
were the main materials used before the era of plastics.
Utilization of plastics in agriculture started in the developed
countries and is now spreading to the developing countries. Early
utilization of plastic was in cold regions, and plastic was mainly
used for protection from the cold. Now plastic is used also for
protection from wind, insects and diseases. The use of covering
techniques started with a simple system such as mulching, then row
covers and small tunnels were developed, and finally plastic
houses. Floating mulch was an exception to this sequence: it was
introduced rather recently, although it is a simple structure. New
development of functional and inexpensive films triggered
widespread use of floating mulch. Table 1.1. The use a/plastic
mulch in the world (after Jouet, 2001).
