2.1 技术简介

技术定义:

Reduced tillage, involving no plowing in the autumn, preserves stubble or plant cover during the autumn and winter to prevent soil erosion, and particle and nutrient loss from cropland to watercourses.

2.2 技术的详细说明

说明:

Purpose/aim: Reduced tillage (i.e., no tillage in autumn) is an efficient measure of preventing soil erosion, and particle and nutrient loss from cropland to watercourses. In addition to the protection of soil from water erosion, stubble fields contribute to increasing organic matter content, which may also increase the aggregate stability of the soil (in the upper soil layers). It is also possible that, as a result of this measure, higher biological activity may improve the soil structure.

Establishment/Maintenance: No tillage in autumn means that cropland areas are left as stubble fields after the harvesting is carried out and they remain like this throughout the winter.
It is of importance to keep in mind the potential for increased amounts of weeds and diseases (incl. fungi) when practicing this measure. The soil may also develop a rather dense structure over time if the climate is humid.

Natural / human environment: The information about Technology is based on the investigations and/or reports from different part of Norway.
For the purpose of the OPTAIN project (https://www.optain.eu/), the technology is further presented in the natural and human environment context of the Kråkstad River catchment - a Norwegian Case Study catchment within OPTAIN project.

The Kråkstad River is mainly situated in Ski municipality in South-Eastern parts of Norway. The river catchment is a western tributary of the Vansjø-Hobøl watercourse, also known as the Morsa watercourse. The Kråkstad River catchment area is c.a 51 km², 43% of which is agricultural land, where mostly cereals are produced on heavy clays soils. The main environmental challenge in the area is water quality (incl. high phosphorus pollution) and soil erosion (incl. riverbank erosion and quick-clay landslides). The Morsa watercourse is a drinking water resource and there are specific environmental regulations for land management followed by subsidies through the Regional Environmental Programme (RMP).
Special regulations in the Morsa catchment (https://morsa.org/) recommend that tillage, and fertilizer additions, are postponed to the start of March at the earliest.

注释（项目类型等）:

The traditional soil tillage method until 1990 was autumn ploughing. From 1991 subsidies (RMP) were given for reduced autumn tillage and during the
period from 1990 to 2002 the autumn ploughed area was reduced from 82% to 43% of the cereal area (Bechmann, 2015). In 2009 about 53% of the grain area
was tilled in spring (Snellingen-Bye et al., 2010). In 2019 about 42% of the grain area was left in stubble during winter (Bjørlo et al. 2021).

However, land users indicate the need for consequent Increased usage of pesticides and reduced production. Subsidies for reduced tillage should compensate for negative effects and costs.

4.7 影响成本的最重要因素

描述影响成本的最决定性因素:

The measure does not lead to any additional expenses for the land user.However, land users indicate the need for consequent Increased usage of pesticides and reduced production.

Under the RMP system (Regional Environmental Programme in agriculture) farmers can apply for subsidies for changed tillage practices. The level of subsidy are based on erosion risk of the area. Depending on erosion risk class, farmer is entitled to ca. 20-200 kr/daa when implementing reduced autumn tillage (RMP for 2019-2022). In exposed watersheds, like those used for drinking water supply (e, g Vansjø- Hobøl catchment) farmers are obliged to implement stricter management practices to receive production support. The farmers in these catchments get higher subsidies than those in other catchments (Bechmann et al. 2016)
