3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation

3.2 Current land use type(s) where the Technology is applied

Cropland

• Annual cropping

Annual cropping - Specify crops:

• cereals - wheat (spring)
• oilseed crops - sunflower, rapeseed, other

Number of growing seasons per year:

• 1

Specify:

Longest growing period in days: 300 Longest growing period from month to month: Sep - Jul

Comments:

Major land use problems (compiler’s opinion): Soil erosion and compaction caused by inappropriate land use and intensive grazing respectively

Major land use problems (land users’ perception): Soil erosion and capping of the soil

Type of cropping system and major crops comments: winter wheat - winter oilseed rape - winter wheat - beans - winter wheat

3.4 Water supply

Water supply for the land on which the Technology is applied:

• rainfed

3.5 SLM group to which the Technology belongs

• minimal soil disturbance

3.6 SLM measures comprising the Technology

agronomic measures

• A3: Soil surface treatment

Comments:

Main measures: agronomic measures

Type of agronomic measures: early planting, manure / compost / residues, mineral (inorganic) fertilizers, soil conditioners (lime, gypsum), breaking compacted topsoil, minimum tillage

3.7 Main types of land degradation addressed by the Technology

soil erosion by water

• Wt: loss of topsoil/ surface erosion
• Wo: offsite degradation effects

physical soil deterioration

• Pk: slaking and crusting

Comments:

Main type of degradation addressed: Wt: loss of topsoil / surface erosion

Secondary types of degradation addressed: Wo: offsite degradation effects, Pk: sealing and crusting

Main causes of degradation: other human induced causes (specify) (economic viability), poverty / wealth (lack of captial), education, access to knowledge and support services (lack of knowledge)

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:

• reduce land degradation

4.1 Technical drawing of the Technology

4.2 General information regarding the calculation of inputs and costs

other/ national currency (specify):

£

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

0.56

4.3 Establishment activities

Comments:

Additional info: - Year2: surface cultivation: mid September / per crop - Year2: drill: mid September / per crop - Year2: roll: mid September / per crop - Year3: shallow sub-soil: November / per crop - Year3: drill: November / per crop

4.5 Maintenance/ recurrent activities

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

Machinery/ tools: Vaderstad Carrier, Vaderstad drill and roller

Only crop establishment costs are included as all other costs - seed, fertilisers, pesticides - are equivalent with those for conventionally mouldboard ploughing. The costs highlghted include labour. Equivalent crop establishment costs by ploughing are 225 (year1), 231 (year2), 190 (year3)

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

slope (steeper slopes require more horsepower), state of the soil, climate, crop

5.1 Climate

5.2 Topography

5.3 Soils

If available, attach full soil description or specify the available information, e.g. soil type, soil PH/ acidity, Cation Exchange Capacity, nitrogen, salinity etc.

Soil fertility is medium
Soil drainage/infiltration is good
