2.1 技术简介

技术定义:

The technology consists of the use of cover crops and of a non-inversion seedbed preparation

2.2 技术的详细说明

说明:

The technology consists of agronomic measures. The most important thing is that the farmers are not allowed to invert the soil by ploughing. Farmers may only cultivate their fields as minimum and as shallow as possible. Farmers also have to use a cover crop, if possible. In this way the soil is always covered with residues of a previous crop or with residues of the cover crop. The improvement of the ground cover protects the soil against different kinds of water erosion. In the long term period, the soil structure will improve (more organic matter in top soil) and more earthworm activity will be determined. The infiltration of water will increase.

Purpose of the Technology: Protecting the soil against erosion and increasing infiltration.

Establishment / maintenance activities and inputs: The farmer may never plough.

Natural / human environment: The technology is applied on cropland with annual crops.

注释（项目类型等）:

In the Walloon part of Belgium and in the surrounding countries (France, Germany), farmers are already applying this technology for a long time. In Flanders, the technology was introduced in the '1970 by a professor De Ploey of our Faculty. Farmers didn't see the benefits of the technology and decided not to implement the technology. Now time has changed: farmers know that they have to do something ageist the erosion problem.

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): 1. Soil loss by water erosion. 2. soil erosion related environmental problems (muddy floods, retention pond sedimentation, declining water quality due to sediment and sediment - fixed contaminants)

Major land use problems (land users’ perception): Strong nitrogen regulations and EU rules are hindering the farmer.

Type of cropping system and major crops comments: Normal sequence of crops at the farm: sugar beet - wheat- potatoes - maize. Crop rotation at the experimental field: maize - wheat - sugar beet.

4.7 维护/经常性活动所需要的费用和投入（每年）

注释:

Comparing to ordinary field operations, there are normally no additional costs if applying the new technique. The farmer will not plough anymore, this is an economic benefit. In some cases and for some crops the farmer will use another machine, for example: the farmer will need a direct drilling machine for sowing sugar beets in stead of a normal sowing machine. In Flanders, always agricultural contractors are sowing beets (not farmers). The agricultural contractor will ask the same price for normal sowing machine as for the direct drilling machine. Although farmers have no additional costs, they get subsidies (80€/ha.year for shallow cultivation, 200€/ha.year for no tillage) from the Flemish Government for practicing the new technique - subsidies are mainly given to encourage the farmers.
