2.1 Short description of the Technology

Definition of the Technology:

Ecological production of almonds and olives under dryland conditions using green manure to increase soil fertility, to protect against soil erosion and to obtain a high-value product.

2.2 Detailed description of the Technology

Description:

Ecological agriculture is a strictly controlled production system that does not use synthetic chemical products like fertilizers, insecticides or pesticides. Also genetically modified organisms and materials are not used. Green manure or low quantities of organic fertilizers, preferably from dung (sheep, goat, cow, chicken), are used to increase and maintain soil fertility. Green manure is provided by seeding a mixture of leguminous nitrogen-fixing species and cereals in autumn (October) and incorporating this into the soil with tillage in springtime (May). To optimize the fertilizer effect, there is still scientific discussion on the need for mowing the green manure and letting it dry for several days before it is ploughed into the soil. For this system, no ploughing is performed in winter, which reduces fuel use and emission of greenhouse gases. In addition to its fertilising effect, green manure provides a continuous surface cover during winter time protecting the soil from erosion. The products grown under this ecological system command a higher market price than those grown under conventional production schemes.

Purpose of the Technology: The aim of ecological agriculture is to protect biodiversity and the environment and maintain or improve soil fertility and reduce soil, water, and air pollution. Under ecological agriculture and by using green manure, soil cover, soil organic matter, and soil biological activity will increase, which positively affects soil structure, soil fertility and soil water infiltration capacity. This reduces the sensitivity of the soil to surface crusting and it reduces surface runoff and soil erosion by up to 60%. Workload and energy use are up to 50% lower than under conventional agriculture, and benefits may increase around 40% due to higher yields. Moreover, a higher market price of ecologically produced almonds and olives will lead to increased farm income. This better economic return discourages land abandonment of marginal lands with low productivities under conventional farming. Ecological almonds and olives production does not require special establishment activities or investments in specialized equipment.

Establishment / maintenance activities and inputs: Infestations by, for example, insects and caterpillars are treated twice yearly by degradable products based on copper salts (Oxicloruro, max 3‰ solution) and mineral oils in winter, or the spores and proteins produced by the bacteria Bacillus thuringiensis or based on natural pyrethrins (from the Chrysanthemum cinerariaefolium; max 1.5 l/ha) in springtime. In ecological agriculture, farmers are obliged to take advice and instructions regarding plague control and fertilizer use from technicians specialized in ecological agriculture.

Natural / human environment: Soils mostly have a shallow to medium depth (between 20-60 cm), and slopes are gentle to moderate (between 5 and 15%). The climate is semi-arid with a mean annual rainfall around 300 mm. Droughts, in summer, commonly last for more than 4-5 months. Annual potential evapotranspiration rates larger than 1000 mm are common. The production system is highly mechanised and market-oriented but depends strongly on agricultural subsidies. All cropland is privately owned.

Comments (type of project, etc.):

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

Comments:

Major land use problems (compiler’s opinion): A lack of water availability seriously limits the production potential of the soil and results in a low vegetation/crop cover. The relatively high soil erosion rates cause various off-site related problems (i.e. flooding, reservoir siltation) and on-site problems (i.e. gully formation and reduced soil depth).

Major land use problems (land users’ perception): There is a lack of water for irrigation of crops limiting the crop types that can be planted as well as the crop yield of dryland farming.

Livestock is grazing on crop residues

Cow dung costs approximately US $350 per tonne and will therefore increase the costs significantly if applied. The costs are calculated assuming the application of green manure, ecological pesticides and organic fertilizer. However, many farmers decide not to use organic fertilizer because of their high costs. As part of the Rural Development Programme (QASPA01), ecological agriculture receives a subsidy of 476 US $ per ha during the first 3 years of production, after which the subsidy is reduced to 380 US $ per ha. Prices are for spring 2008.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Ecological agriculture and green manure have a very positive effect on soil quality, biodiversity and reduction of runoff and erosion How can they be sustained / enhanced? Reduced costs related to pest control
High quality products of ecological agriculture provide a good impression and an attractive product How can they be sustained / enhanced? Better marketing of eco-almond and olives

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?
Application of green manure is competition for water for the crop.	Plough away the green cover on time in spring before competition becomes important. Moreover, provide demonstrations on the effects of green manure on competition and crop productivity by additional nitrogen input.

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Application of organic fertilizers and ecological pest control is relatively expensive and depend on subsidies especially in the first few years of implementation	Look for cheaper methods and combine possibly with other techniques such as reduced tillage to further reduce the costs. After several years, normally less pest control is required due to increased natural control and ecosystem integrity.
