2. SLM技术的说明

2.1 技术简介

技术定义:

Silvopastoral Agroforestry in a natural farmed environment – This is an alley cropping system with rows of Perry pears and timber trees inter-planted with coppiced willow and alder. The pasture in between the rows is mob grazed with young dairy stock.

2.2 技术的详细说明

说明:

Background: The agroforestry system is part of a mixed farm of 630 hectares. 550 hectares are rented on a three generation tenancy. The farmer is the second generation. The trees are planted on the 80 hectares owned by the farmer. The annual rainfall for the region is approximatly 630mm per year with a typical temperate UK climate. The soil is heavy clay on a flat landscape.

The system: The field is 19 hectares. The trees are planted in rows which are 27 m apart. There is a main species in each row, planted at 10 m spacing. These are inter-planted with smaller trees, or species that will be coppiced/pollarded to maintain a small form. The main species are: Perry pear (a small pear that is a cross between Pyrus communis and its wild subsp. pyraster – used to make the alcoholic drink “Perry”). We have also some species planted for timber Quercus robur, Sorbus torminalis, Carpinus betula, Prunus avium. The inter-plant species are Salix various sp., Alnus glutinosa. These will be used either for animal fodder or for chipping and used as a mulch or for spreading on the land as soil health improver. There are also some Hippophae rhamnoides for human consumption. The alleys between the rows of trees are grazed by young dairy stock on a mob grazing rotational basis.

Aims: The aim is to improve soil and drainage in the field which is heavy clay. We hope to improve productivity but also have designed the system that we can grow crops in the future if we wanted to. The trees will also provide benefit to the cows through shelter and shade, and the inter-plants of willow and alder grow through diverse forage.

Tree protection: Fencing was our major challenge. There needed to be protection from the livestock but also from wildlife (in particular deer and hares). Our initial trial used individual guards and stakes but we have since fenced each side of each row with a single strand of electric fencing. This is working well.

Benefits: This is newly planted but already we are seeing improvement in the grass ley through our rotational grazing. Water quality into the nearby stream and infiltration improved and flooding should also improve. We have seen an immediate increase in wildlife with greater numbers of hares, raptors (including kestrels, red kites and buzzards), and butterflies. The farm manager likes the ability to mob graze, although the system was complicated to set up. It is too early to comment on further benefits at this stage.

Future opportunity of land and business diversification
Increase in biodiversity evident already and would expect further improvements.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险 如何克服它们?
Tree loss due to weather extremes (i.e. loss of young tree stock in 2018 summer drought) Mulching, irrigation, earlier planting, improved placement of tree stock on edge of sub-soil slot where less soil drying occurs compared to centre of slot.
Perenial weed control poor using just wood chip mulch Increased strimming management of the growth around trees where livestock cannot reach due to fencing.
Time investment against other commitments (i.e. priority of broader farm systems when attention to new technology is required) Forward planning and improved communcation between the farm team is vital to ensure a sufficient amount of time is provided for attending to and learning about a new technology.
编制者或其他关键资源人员认为的弱点/缺点/风险 如何克服它们?
Overall costs against short-term return Secure funding to enable longer-term return.
