![]() This system is most likely to be operated by contractors or grower co-operatives because of the initial high investment in machinery. There are two main systems for harvesting SRC:ĭirect cut systems are based on principles used for other agricultural crops, where the whole crop is cut and chipped or billeted in one operation. With this in mind, it might be possible to have three different age-classes of SRC in one 10-hectare field. The average harvesting of SRC, using a chipper or mechanical harvester, is around three hectares a day, depending on the type of harvester used and the size and layout of the plantation. SRC is usually harvested after two to five years’ growth. The system used to harvest, store and transport the SRC crop depends on the scale of the operation, the specification of the end user and a host of local factors such as access and road size. Typical data on short rotation coppice in Europe Species ![]() Converting existing arable land to SRC will reduce the amount of agricultural chemicals required as SRC is a low input crop: once established it requires a very much lower input of chemicals than conventional arable crops. It is one of the factors, together with better pest management, which may lead to increased productivity. Research is continuing into the optimum spacing between varieties. 90 cm spacing between rows of cuttings and 75 cm spacing between cuttings in a double row will allow for tractor access. There would usually be about 1.5 metres between double rows of cuttings so that the side walls of the tires of the tractor are not damaged by the cut crop. Planting in twin rows allows harvesting of two rows at a time, usually using direct cut and chip methods (see Harvesting and Transport chapter for details). The development of SRC for renewable energy production is a new sector with potential for considerable expansion, offering benefits for growers, developers, consumers, local communities and the environment.Ī typical plot might be from 10,000 to 20,000 cuttings per hectare. As a rotation crop, SRC is harvested at specific intervals, to provide a regular and constantly renewable supply of fuel. Short rotation forestry refers to the growing of trees (usually willow or poplar) in extremely dense stands, harvested at 3-4 years intervals and regenerated from the stools, which are expected to survive 5 rotations at least.
