Straw

Straw is an agricultural byproduct, the dry stalks of cereal plants, after the grain and chaff have been removed. It makes up about half of the yield of cereal crops such as barley, oats, rice, rye and wheat. It has many uses, including fuel, livestock bedding and fodder, thatching and basket making.

Uses

Straw is used in a variety of ways, depending on its intended end use.

Livestock bedding

Straw has been used as a bedding material for animals for centuries. It provides a comfortable and warm surface for animals to rest on, and can also be used as a source of fodder.

Thatching

Straw is commonly used in the construction of thatched roofs. This traditional roofing method is still used in many parts of the world, and provides a durable and weather-resistant covering for buildings.

Basket making

Straw is also used in the craft of basket making. It can be woven into a variety of shapes and sizes, and is a popular material for this purpose due to its flexibility and strength.

Production

Straw is produced as a byproduct of the harvesting of cereal crops. The grain is harvested and the remaining stalks are left to dry out in the field before being baled and stored for later use.

Environmental impact

The production and use of straw can have a significant impact on the environment. It is a renewable resource, and its use can help to reduce reliance on non-renewable resources. However, the burning of straw can contribute to air pollution, and its use as a bedding material can lead to the production of methane, a potent greenhouse gas.
