2.1 Технологийн товч тодорхойлолт

Технологийн тодорхойлолт:

Improved soil management based on non-inversion tillage for cost-effective and timely crop establishment.

2.2 Технологийн дэлгэрэнгүй тодорхойлолт

Тодорхойлолт:

Conservation agriculture (CA), involving superficial non-inversion tillage, began to be widely taken up in England following advances in seed drill technology, non-selective herbicides and straw-chopping combine harvesters in the late 1980s.
This case focuses on the Game Conservancy Trust’s Allerton Project at Loddington, which in 2000 pooled resources with its neighbour to purchase a single set of cultivation equipment, and replaced conventional mouldboard ploughing (with its multiple cultivations) by state-of-the-art CA. Contract services offered by the joint venture means that 1,000 ha are now covered each year. The main winter crops are wheat, oats, and oilseed rape. Beans are sown in the spring. The heavy clay loam is vulnerable to excessive surface moisture, restricting crop establishment
‘windows’.
Immediately after harvest the soil is loosened and straw incorporated, and then soil is consolidated (using a ‘cultivation train’ combining two machines: the ‘Simba Solo’ and the ‘Cultipress’). This encourages up to 60% of the weeds to emerge in a ‘stale seedbed’. Spraying then removes all the weeds and volunteer plants of previous crops. This is followed by a light surface tillage, using the ‘Väderstad Rapid Cultivator Drill’, before sowing into the seedbed created. Equipment comprises implements with tines and/or discs which create a tilth to around 10 cm
without inverting the soil. Cambridge rollers are then used to consolidate the sown land. After crop maturity, combine harvesting takes place - with simultaneous chopping of straw/crop residues. A trash rake is used to disperse the chopped straw. This way excessive trash is incorporated rapidly into the soil. Compaction may arise in the transition phase, because of the lack of soil loosening through ploughing: minimising traffic, keeping to tramlines and headlands can all help. In time, increases in soil organic matter content and earthworm biomass make compaction less of a problem. The problem of slugs can be reduced by improving seed-to-soil contact, and by drilling deeper.

Purpose of the Technology: The main purpose of conservation agriculture is cost effective, timely and rapid crop establishment, under good soil conditions. High-speed operations are the key. Compared with conventional ploughing, labour is saved and fuel costs lowered. However, an additional application of herbicides represents an extra expenditure. Yields per hectare haven’t risen but the key difference is that about four times as many hectares can be prepared in time for autumn planting under conservation tillage, thus improving overall production. Incorporation of crop residues improves soil structure and leads to a more friable, less erodible topsoil.

Тайлбар:

Major land use problems (compiler’s opinion): Traditional inversion tillage is slow and costly. By moving to high speed non-inversion conservation tillage farmers can
spread costs over a larger area and maximise the area under winter crops. The speed at which ground can be worked in the autumn is critical: one month earlier planting can mean an extra ton in cereal yield.

4.8 Зардалд нөлөөлж байгаа хамгийн чухал хүчин зүйл

Өртөг, зардалд нөлөөлөх гол хүчин зүйл:

No establishment costs for purchase of special conservation tillage equipment are included here – though this
investment is considerable. Tractors of sufficient horsepower and a couple of special machines (see above) are needed. The investment in this case was shared by two neighbouring farms, who implemented conservation agriculture on a joint venture basis. The only costs presented in the table above are total recurrent annual costs for tillage operations. This total, US$ 180, compares with US$ 260 for conventional tillage operations. While drilling is not included in the above conventional tillage calculation, subsequent application of additional herbicides represents an extra cost of conservation tillage of about US$ 80/ha. In balance the costs per hectare are broadly similar. Labour inputs however are reduced considerably as a proportion: the Allerton farm with its 260 ha of arable land is operated by a farm manager and just one farm worker.

Тайлбар:

There is a strong trend towards spontaneous adoption of the Technology

Comments on adoption trend: Extent of adoption depends on farm size, enterprise & soil type. From 10% in 95, approx 40% of arable land in Eng is currently (04) under conservation agriculture/cultivation tillage.

Additional info: Farmers involved adopted the system without incentives other than those of timeliness, lower cost, speedier crop establishment, reduced soil erosion & benefits to wildlife. There is significant growing spontaneous adoption: the extent of adoption depends on farm size, enterprise & soil type. Editors’ comments: Conservation agriculture is rapidly catching on throughout the world. While most attention has been focussed on the Americas, a revolution is taking place in Europe also. In England, for example, around 40% of the large scale arable area is now under CA – a rise from just 10% a decade ago. CA helps to minimise costs and reduce local, and global, environmental impacts. This is a case from a leading proponent of CA in England. Comparative case studies are documented from Morocco, Australia and Kenya.
