The term plasticulture is used to describe the broad and general use of
plastics in agriculture. Plasticulture can extend the growing season and
improve crop health and growth. This web page includes links to information
on the use of plasticulture in the form of plastic mulch, degradable mulch,
tunnels (low and high), hoophouses, greenhouses and agricultural plastic
recycling as well as crops most often grown with plasticulture, and
agriculture plastic recycling in the Northwest. For an overview of why and
how season extension can be accomplished through plasticulture, see:

    * Season Extension Techniques. Season extension can enable year-round
crop production as well as higher-quality produce. This publication
describes season extension techniques and provides sources for equipment,
supplies, and further information. ATTRA.

Mulch

Plastic mulch is commonly used to control weeds in the crop row, moderate
soil temperature and conserve water in the plant root zone. There are many
different colors and qualities of plastic mulch, and use varies depending
on the season and crop being grown. There are also degradable mulches made
of cornstarch and paper, and plastic mulches that are heat and/or light
degradable.

Structures

Various types of structures are available to lengthen the growing season
for the crop and improve overall crop health and quality. The following are
just a few of the structures available, such as high tunnels, low tunnels,
hoophouses, and greenhouses. Structures that are used for winter production
must be able to withstand heavy rainfall, snow, and wind. Structures that
are used for summer production must have good ventilation. Many structures
may not be suitable for year-round production.

Recycling

Recycling is a common issue faced by agricultural plastic users. The cost
of removing and disposing of agricultural plastics can be high. Following
are some programs and companies that offer agricultural plastic recycling
in the Northwest.

Northwest Ag Plastics, Inc. Offers recycling for mulch film, drip
irrigation tape, row covers, tunnel film, greenhouse film, and more. Also
offered are recycling services for rigid plastics such as buckets,
barrels/drums, and irrigation pipe.

RE Sources. Offers education to the public on a variety of local
environmental issues connected with plastic use and recycling.
