2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The cultivation of perennial herbaceous fodder plants to be used to fertilise unproductive cropland, and as permanent crops to be used to increase farm fodder production.

2.2 Detailed description of the Technology

Description:

Perennial herbaceous fodder plants such as alfa-alfa and esparzet are cultivated for fodder production and to fertilise unproductive cropland. Esparzet and alfa-alfa are often grown on steep slopes not suitable for annual cropping and on unproductive cropland as green manure. Alfa-alfa and esparzet can be harvested for 6-10 years without tillage.

Purpose of the Technology: These crops fix nitrogen, so they help fertilise the soil so that farmers can plough or harrow the land after 5-10 years to grow annual crops again.Alfa-alfa and esparzet can be harvested for 6-10 years without tillage (depending on the soil characteristics and inclination).

Establishment / maintenance activities and inputs: As yield from perennial herbaceous fodder plant fields starts declining around 4-6 years after the initial cultivation, farmers make up for declining yields by applying additional seeds. Alfa-alfa and esparzet can be harvested twice a year (3-4 harvests a year if irrigated), which results in a significantly higher annual farm fodder production in comparison to ordinary haymaking fields.

Natural / human environment: Some farmers reported problems in growing esparzet or alfa-alfa on slopes with an inclination of more than 30%. However, various examples have shown that these perennial herbaceous fodder plants can be cultivated on steep slopes of up to 60%. On steep slopes an extra amount of seeds must be applied to offset those lost downslope by washing before germinating. Alfa alfa and esparzet are effective in reducing soil erosion since their cultivation leads to an more intact ground cover throughout the year. Furthermore, not needing to tillage for up to ten years helps conserve the soil resources.

3. Classification of the SLM Technology

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

Cropland

  • Annual cropping
  • Perennial (non-woody) cropping
Annual cropping - Specify crops:
  • fibre crops - flax, hemp, other
  • cereals - wheat (spring)
  • fodder crops - alfalfa
  • vegetables - other
  • esparzet
Number of growing seasons per year:
  • 1
Specify:

Longest growing period in days: 210Longest growing period from month to month: Mar - Aug

Comments:

Major land use problems (compiler’s opinion): severe soil erosion (gullies and rills) and subsequent fertility decline on the cropland and overgrazed pastures

Major land use problems (land users’ perception): fertility decline, soil erosion and washing downslope of seeds before they can sprout.

Type of cropping system and major crops comments: If perennial herbaceous fodder plants are used as green manure, farmers will try to grow annual crops again 6-10 years after the initial cultivation. If crop yields remain low, farmers resort to growing herbaceous fodder plants as permanent crops.

6.5 Adoption of the Technology

If available, quantify (no. of households and/ or area covered):

NA

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 91-100%
Comments:

100% of land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: estimates

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: Instead of leaving unproductive cropland uncultivated, some farmers have recently started cultivating alfa alfa or esparzet. Often esparzet is preferred by farmers to alfa alfa, since espartzet-hay is easier to feed to animals because of its hollow stem.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
increase of fodder production
fertilises unproductive cropland
easy to feed to cows in winter
in comparison to ordinary hayfields, two to three harvests are possible
only a few inputs required
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
increase farm production of good quality fodder

How can they be sustained / enhanced? If land is irrigated three, (instead of two) harvests are possible each year
reduces soil erosion through an intact ground cover being present throughout the year

fertilizes soil through nitrogen fixation

easy to implement, easy to maintain
involves only little costs for establishment, almost no inputs for maintainance
can be used to improve canopy cover on uncultivated (abandoned) cropland
no tillage necessary for 6-10 years

How can they be sustained / enhanced? additional application of seeds when yields start declining

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?
loss of possible cropland higher return from fodder production than for limited crop production on degraded land
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
loss of land which could have been used for production of food crops cultivate perennial herbaceous fodder plants especially on land which is unsuitable for production of annual crops
increase of farm fodder production allows farmers to have more animals which ultimately will lead to further overgrazing of pastures keep animals in stables - cut and carry system
