1.5 参考关于SLM方法（使用WOCAT记录的SLM方法）的调查问卷

2.1 技术简介

技术定义:

Reduced tillage of cropland areas to decrease erosion by water and soil loss.

2.2 技术的详细说明

说明:

Cropland areas with high erosion risk are left as stubble fields after the harvesting is carried out and throughout the winter. Special regulations in the Morsa catchment (cf. morsa.org) suggest that tillage and fertilizer additions are postponed to the 1st of March at the earliest.

Purpose of the Technology: Reduced tillage is an efficient measure to prevent 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 heighten the organic matter content, which may also increase the
aggregate stability of the soil. it is also possible that higher biological activity may improve the soil structure.

Establishment / maintenance activities and inputs: It is of importance to keep in mind a potential increased amount 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. On areas of low erosion risk, cultivation by autumn harrowing to a depth of 80 to 120 mm, followed by repetitive spring harrowing to a depth of 60 to 100
mm, may be beneficial. The methods are likely to contribute to faster decomposition of
plant material, and to reduce the occurrence of weeds. Direct seeding to stubble fields of young meadow is another method, but requires special equipment and is not very common in this catchment.

Natural / human environment: The Kråkstad River is mainly situated in Ski commune in Akershus County in South-Eastern parts of Norway. The river catchment is a tributary of the Vansjø-Hobøl watercourse, also known as the Morsa watercourse. The Kråkstad River catchment constitutes a total area of about 22 km², consisting mainly of cropland and forest/woodland. The recipient Vansjø is a eutrophic lake with a former history of algal blooms of toxic cyanobacterias. The lake is both used as a drinking water source and for recreational purposes.
