1、Where can you buy straw bales? A good place to start is stock and station agents. Often they will know of farmers who sell straw bales. Generally harvesting will take place in early summer, so that is the best time of year to look for straw bales. Bales can be purchased from stock feed suppliers, bu
2、t normally they will be much cheaper direct from farmers, preferably direct from the field after harvesting and baling. Before buying straw bales, check that they are reasonably tightly bound, have a generally good appearance, are not distorted, are dry and do not show signs of having previously bee

The type of straw seems not to be very important, but straw that is composed of stiff, rather than soft, stalks and has mainly long stalks is probably better. Some suggest that the
4、 higher silica content in rice straw is desirable, though oaten straw, for example, has stiffer straws than rice straw and can produce a better face for plastering when well trimmed. One could analyse the finer points of the different straws, but there are much more significant issues to consider. U
5、sually the straw that is most readily available is the most appropriate, because the cost, particularly the transport cost, probably will be substantially lower than for other options. Handling and transporting bales Handling and transport of straw bales can be a major effort and significant expense

Standard straw bales are quite heavytypically a bale weighs about 20kg but they can be considerably lighter or heavier, depend

Therefore, one should be fully conversant with the theory and practice of safe manual handling before attempting to load a truck, build a wall, or do any handlin
8、g of straw bales. This subject is covered exhaustively in safety publications. Transporting straw bales is not trivial. Except perhaps for the very smallest of jobs, an experienced carrier should be engaged to collect and transport the bales, and to stack them in the storage location. An untrained p

If a car-trailer is used to transport bales, be carefula car trailer cannot safely carry many bales before it becomes unstable, too heavy and very d
10、ifficult to properly secure the load. Storing straw bales The best practice is to have the bales delivered to the site after all other preparations have been made and everything else is ready for wall construction. Thereby, most of the problems of storage can be eliminated. If the bales will be requ

Check with the supplier of bales to determine their availability at different times of the year. The bales must be kept dry at all times. Once wet through the bales will dry very slowly and are li

It is important to plan carefully the storage of bales before making procurement and transport arrangements, even if a very
