Application of sulphurous amendments for alteration of soil pH near Wareham, Dorset. (Mark Tibbett)

Soil pH management (英国)

描述

Acidification treatments were applied to improved pastures in an attempt to restore plots to low-intensity grazing land

Aims / objectives: To convert the area from intensive pastureland to a semi-natural state with low intensity grazing through alteration of the soil pH. This change in land-use should have a positive effect on both above- and belowground biodiversity.

Methods: Plots were established on two adjacent farms owned by National Trust near Wareham, Dorset (Newlines Farm and Hartland Farm). A control and two sulphur amendments were compared on plots on ten fields (five from each farm) on 50 m x 50 m plots. Elemental sulphur (Brimestone 90TM) or ferrous sulphate (Mistrale “Wet Copperas” 50TM) were applied at equal rates of 2000 kg ha-1 in May 2000 and a second application of 1600 kg ha-1 in March 2001.

Stages of implementation: Treatments were applied in 2000 and 2001. Periodic monitoring has been conducted to monitor changes in plant diversity and soil chemical and biological properties.

Role of stakeholders: Stakesholders played an active role in identifying management options and implementing the technology. When the original plots were established, a charitable organisation was the primary stakeholder. For the intent of the current project, other stakeholders became involved, including parish council, landowners, and conservation organisations.

Other important information: Acidification treatments were applied to plots on the Isle of Purbeck that had previously been used for arable production and then high intensity grazing. The site is located on acidic fluvially-deposited soil and was in lowland heath until the middle of the 20th century at which time the land was tilled and treatments of rock phosphate, marl and chalk were added to increase soil pH and nutrient availability and improve the potential of the land for agricultural production.

方法目标和有利环境

该方法的主要目的/目标
The Approach focused mainly on other activities than SLM (soil, pH, below-ground biodiversity, low-intensity grazing)

To manage soil pH change and associated effects on above and below-ground diversity and function

The SLM Approach addressed the following problems: Management of soil pH and land use change to less intensive system
推动实施本办法所应用技术的条件
  • 法律框架（土地使用权、土地和水使用权）: The existing land ownership, land use rights / water rights greatly helped the approach implementation: The land where the approach was implement was managed by National Trust UK who had a special interest in reclamation and conservation.
阻碍实施本办法所应用技术的条件
  • 社会/文化/宗教规范和价值观: Local confusion about land use change Treatment through the SLM Approach: Public workshop explained reasons to stakeholders
  • 财务资源和服务的可用性/可得性: Loss of earning as less intensive system is less productive Treatment through the SLM Approach: Ecological benefits balance against economic losses

结论和吸取的教训

长处: 土地使用者的观点
  • Decreased spending on inputs where the only input in the system in dung from cattle grazing (How to sustain/ enhance this strength: Continue grazing at a low enough density to allow adequate plant regrow)
  • Decreased labour required for management
  • Decreased compaction since regular use of tractors on site is no longer required (How to sustain/ enhance this strength: Attempt to minimizing compaction by grazing livestock)
长处: 编制者或其他关键资源人员的观点
  • The conversion in land use from a improved agriculture to a semi- natural low input grazing system should have a positive effect on above- and belowground biodiversity.
  • Considering that the Isle of Purbeck was historically a region of cultural importance, returning the system to a more natural state has important implications for the cultural and recreational value of the land.
  • Low input systems can increase resilience of the system to global change
弱点/缺点/风险: 土地使用者的观点如何克服
  • Fertilizer application rate too high for one application Smaller, regular additions over several years
  • Decrease in economic returns
  • Shrub encroachment (i.e. gorse; Alex europaeus) can be a problem when converting to low input pasture land in this region. Grazing, mowing, and chemical herbicides are some options for slowing invasions.
弱点/缺点/风险: 编制者或其他关键资源人员的观点如何克服
  • Over time nutrients are being drawn down but exporting meat off the land with no inputs Periodic applications of nutrients may be required to ensure long-term fertility of the system
  • Land use change and restoration are slow process and may result in economic losses on managed lands
