2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Current wheat crop in yearly rotation with chickpea cultivation
2.2 Detailed description of the Technology
Description:
The rainfed crop of the farmer sizes around a hectare. He owns the crop since seven years and switches between chickpea and wheat every year. When he started to cultivate, soil properties were good, he did not use fertilizer. Because of the years of ploughing, the soil lost nutrients and moisture. The more rill building and slope instability is severe currently. The plot is over one hectare because it includes a narrow vegetation strip between his and the neighbours crop. The plot, as all the other crops are grazed by livestock, after harvest.
Purpose of the Technology: Chickpea cropping generates a satisfactory yield, whereas wheat production is rather variable and low. Nevertheless the farmer would not change the crop type because the main purpose is to get straw for feeding his cows. The farmer has over three hectares in total. Even though he claims the benefit to be low comparing to the input, he is content as long he can feed his family.
Establishment / maintenance activities and inputs: Ploughing, sowing and then harvesting were part of the establishment phase. The same activities count for maintenance. But as soil is gradually washed away, fertilizing became crucial. The farmer does not control and protect the crop from wild animals and grazing herds.
Natural / human environment: The crop lies on a foot slope not far from the riverbed. Neighbouring cultivations are of the same crop type, chickpea, wheat and food grain. It is less than one kilometre away from the farmers home in Doshmand village. Access to services is rather low, especially in winter, because of the bad condition of the road. Doctor, middle and higher school grades and market are in the village below.

×3. Classification of the SLM Technology
3.1 Main purpose(s) of the Technology
- improve production
- reduce, prevent, restore land degradation
3.2 Current land use type(s) where the Technology is applied
Cropland
- Annual cropping
Main crops (cash and food crops):
Major food crop: Wheat
Comments:
Major land use problems (compiler’s opinion): Sealed and compacted topsoil, which hinders infiltration. Hardpan is propable due to plowing. Erosive processes with rill building are relatively widespread on the crop. A lot of plowing rills aggrandize by runoff. A lot of licorish plant grow on the crop, which is a indicator for degraded soil. Soil shows a low level of organic matter, nutrients and moisture.
Major land use problems (land users’ perception): Increasing soil wash out with simultaneos augmentation of fertilizer input over years. Rills destroy crop growth, reason why yield quantity and quality is decreasing.
Type of cropping system and major crops comments: Farmer doesn't try hard to get a better yield. As long as he can feed his family he doesn't see the real need to do that.
Livestock is grazing on crop residues

Farmer knows that there is no real benefit when looking at the input. Over the years it got slightly negative because more fertilizer is needed and yield is decreasing.
6.7 Strengths/ advantages/ opportunities of the Technology
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view |
---|
Vegetation strip underneath the crop is an idea to develop as it reduces the negative offsite effects. How can they be sustained / enhanced? Knowledge transfer about how to reduce offsite effects. Soil cover could rise in that strip, thanks do what soil erosion woul be stopped. Enhance communication between above and below vegetation strip cultivating farmers. |
Maintain and develop crop rotation. How can they be sustained / enhanced? Knowledge transfer and field studies on other plots with crop rotation (e.g. perennial crops). |
Plowing horizontally. |
6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view | How can they be overcome? |
---|---|
Too much soil erosion causes rills. | Another crop type according to the steepness of the plot. Change plowing deepness or do human-powered tillage. |
Development of soil crust, sealing and hardpan. | Enhance crop rotation and "soft" and horizontal tillage practices. |
Observed trampling and grazing of the plot. | Guarding or fencing of the plot. Guarding could be organized by several farmers in rotation. |
Poor pecentage of organic matter. | Introduce mulching. |
