2.1 Short description of the Technology

Definition of the Technology:

A no-till system with crop residue management for mediumscale wheat and barley farming.

2.2 Detailed description of the Technology

Description:

This no-till technology (NTT) system, with direct seeding and crop residue management, was designed by the National Institute of Agricultural Research (INRA) in Settat, Morocco. A special no-till drill was developed to simultaneously seed and fertilize annual crops: the drill cuts through residue, opens a 20 cm wide slot which, after seed and N/P-fertilizers are dropped into it, is closed firmly to encourage contact between seed and soil. Seeding is earlier than in the case of conventional tillage – which requires seedbed preparation. Spacing between rows is adjusted according to crop type: 20 cm for wheat or barley, and 40 cm for lentils and chickpeas. Tillage depth is between 5–12 cm depending on soil workability and moisture content.

Establishment / maintenance activities and inputs: Crops, planted in rotation with a fallow period, are barley, wheat, legumes (lentils and chickpea) and also fodder species. Application of special herbicides replaces tillage for weed control, and enables the farmer to have an 18-month fallow period (a ‘chemical fallow’) after two crops have been taken over a 6-month period. Fallowing is essential for water conservation in this semi-arid area. NTT reduces passes with heavy machines to three times per year. Residue management involves maintaining the soil partially covered with stubble and straw. Overall, yields are higher and costs are lower than under conventional tillage. NTT reduces soil erosion and soil compaction while conserving water in the soil. Optimum use of scarce and low rainfall to stabilise/increase crop yields is essential in this area.

Natural / human environment: The use of the special no-till drill ensures both minimal working of the soils, and precise incorporation of phosphate fertilizer beneath seeds. Depending on the specific site, residue management is adjusted from low residue maintenance (stubble/controlled grazing) to medium surface cover (stubble/straw maintenance, forage crops and exclusion of grazing). Erosion and evaporation suppression/control are the main impacts of the system: runoff and concentrated flow in watersheds are reduced. Chemicals are applied for weed control, but this takes into account the environment, and can be reduced over time. Maintaining crop residues in the fields increases soil organic matter and thus the amount of carbon sequestered, as well as nutrient levels. Hence application of inorganic fertilizers can be reduced.

Cropland

  • Annual cropping
Specify:

Longest growing period in days: 180; Longest growing period from month to month: November to April

Comments:

Major land use problems (compiler’s opinion): Conventional tillage practices are often inappropriate, leading to various problems: disk plough operations make soils more vulnerable to erosion, evaporation, loss of organic matter and nutrients (due to inversion of soil) and thus reduce soil fertility. Furthermore, land preparation often takes place when soils are too dry or too wet. The soils in this area have a weak structure, due to low organic matter content, and are thus susceptible to compaction. Energy input in conventional tillage is much higher than in NTT.

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

Annual recurrent costs are calculated on a two years basis, including a 6-month cropping and 18-month fallow period, divided by two. The initial cost for the no-till drill is calculated – on a per hectare basis – for an average farm size of 10 ha. In this case a ‘pilot’ farmer’s case is taken, where the drill is supplied free. As with conventional drills, a new no-till drill costs US$ 6,000 but it is subsidised by up to 50% by the Government. Thus farmers can buy it for US$ 3,000 (though ‘pilot’ farmers receive it free of charge – as noted above). They have no extra costs (compared to conventional tillage) and they can share the price of the drill between them if they wish. The price of certified seeds and fertilizers, energy and equipment are the main factors affecting the costs of no-till, when subsidies are cut after the pilot phase. However, the costs of NTT are lower than for conventional farming, even when the cost of the drill is included.

6.4 Cost-benefit analysis

How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:

slightly positive

Long-term returns:

very positive

Comments:

Pilot farmers receive the no-till drill fully financed by the project (thus no benefits under investment costs’ above). Farmers who purchase the drill on their own (with a 50% subsidy)
will recover its cost in less than two years.

6.5 Adoption of the Technology

  • 1-10%
If available, quantify (no. of households and/ or area covered):

14 households in an area of 20 km2

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 0-10%
Comments:

14 land user families have adopted the Technology with external material support

Comments on acceptance with external material support: All the 14 pilot farmers accepted the technology with incentives, receiving all inputs (machinery, seeds, fertilizers and biocides) in the first 3 years.

Comments on adoption trend: These pilot farmers are still in the phase of adoption. Out of the 14 farmers, there are two or three that still resist the change. Farmers’ attitudes alter slowly and complete acceptance is only reached after several years.

How can they be sustained / enhanced? Refine the integrated crop management
and pest control system.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Costly machinery (drills, tractor, sprayer) required Subsidies, purchase
of equipment by groups of farmers.
Weed control in NTT is critical: weed infestation if not well managed;
high cost of herbicides
Apply environment-friendly herbicides, crop diversification; hand weeding.
Socio-economic constraints of Moroccan farmers Technology needs a long-term approach for full acceptance and implementation.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
High level of management is required Training of land users.
Sensitive to nitrogen level management Soil tests/apply N according
to needs of crops under NTT.
High disease and pest prevalence if crop residues are not well managed Resistant varieties and early seeding of diverse crops.
Reduced availability of straw (fodder) Optimise crop/livestock integration: straw production under NTT is higher but farmers have to be convinced to remove only part it; use fodder crops in rotation.
Unforeseen environmental risks: eg soil or ground water contamination
with herbicides/phosphate
Training, video presentations etc.
