2.1 Short description of the Technology

Definition of the Technology:

Establishment of blueberries cultivation in plant pots on soils with bad physical or chemical properties. The technology improves productivity and generates income for the farmers. The implementation requires drip irrigation system.

2.2 Detailed description of the Technology

Description:

The cultivation of blueberries in plant pots has been successfully implemented in the area of Živinice municipality - on soils of poor composition, physical properties and low fertility. Many efforts have been made to introduce a conventional production of blueberries but did not bring the expected results due to the bad soil quality.
The soil (Stagnogley) is poorly permeable to water, so even moderate rainfalls cause water remain on the surface, making it difficult or completely impossible to cultivate the land. In addition, soils of high acidity are required for the successful cultivation of blueberries. Planting blueberries in a conventional way is often carried out on soils where the acidity is increased by various additives (often with wood sawdust or similar wooden materials). Practical experience has showed that in the course of time the acidic properties of the soil in the zone of the development of the blueberry root change, i.e. soil/substrate acidity decreases due to resorption processes on the primary soil. Todays' market offers multi-component substrates for the cultivation of blueberries, which, in addition to their adequate acidity, have other properties necessary for a good development of the blueberry's root system. These substrates were also used in some localities of the municipality of Živinice in conventional or modified conventional planting of blueberries (on embankments using soil and commercial substrates). This technique did not yield satisfactory results, probably because of the loss of substrate properties (decrease of soil acidity) due to resorption to the nearby original soil. The substrate keeps its desirable properties much longer if it is put into the planting where blueberries are being planted.
The basic advantage of this technology is its ability to be applied on practically all soils of poor agricultural-productive properties, including heavily degraded and low water permeable soils. Even if the cost for introducing the technology is relatively high, its maintenance is reduced to standard agro-technology (fertigation, plant protection, weed control, harvesting, etc.) due to the type of crop. In the Živinica municipality, technology is currently being applied only in the cultivation of blueberries. The results have shown that the cultivation of blueberries in plant pots provides a yield of about 15 t/ha, which is about 5 t/ha (50%) higher than in the conventional cultivation of the blueberries. The farm on which the technology is described cultivated blueberries of the Duke variety on 8 ha whose fruits are sold at prices between 3.50 and 4.50 USD/kg. The estimated life span of the blueberries grown in plant pots under full yield is 15 years.
Regarding the technical characteristics of the SLM technology, the plant pots with blueberry plantings are placed in rows of low trenches with a distance of 100-120 cm between the plant pots (from center to center); and 250-300 cm between rows. The plant pots (60 to 90 liters) are placed in later formed embankments (trussing with the original soil), thus ensuring the stability of the plant pots (e.g. from wind) and more favorable temperature and humidity conditions of the substrate in the plant pots. The technology implies possession and use of the drip irrigation system, using the water collected in accumulations and distributed from tanks situated on the farm.
The technology offers relatively innovative use of infertile or degraded soils for the intensive and profitable production of blueberries or other crops, primarily berry fruits. Positive experiences from the implementation of the technology on about 8 ha, on the observed farm resulted in the replacement of the earlier conventionally planted and grown blueberries in the wider area of Živinice. By expanding blueberries cultivation in wider areas, the municipality is considered among the leading blueberry producers in the Balkans.

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through land users' innovation

Comments (type of project, etc.):

The technology was introduced by the endorsement of the Municipality.

3.1 Main purpose(s) of the Technology

• improve production
• reduce, prevent, restore land degradation
• create beneficial economic impact

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

Cropland

• Tree and shrub cropping

Number of growing seasons per year:

• 1

Comments:

The land, where the described technology is applied, is characterized by bad soil physical properties (heavy soils, poorly permeable to water, even moderate rainfalls do not allow movement of workers and mechanization).

3.7 Main types of land degradation addressed by the Technology

chemical soil deterioration

• Cn: fertility decline and reduced organic matter content (not caused by erosion)

physical soil deterioration

• Pc: compaction
• Pk: slaking and crusting
• Pu: loss of bio-productive function due to other activities

4.3 Establishment activities

Comments:

Preferably blueberry plantings are 3 or 2 years old, in plant pots (containers) not smaller than 2 liters.

4.4 Costs and inputs needed for establishment

Comments:

Ground leveling with use of mechanization is not necessary on plain or relatively plain terrains.
The cost of 2 or 3 years old blueberry planting in small (2 l) container include delivery (on farm) costs.
The costs of plastic plant pots (65 l) and substrate for blueberries include delivery (on farm) costs.
The price of drip irrigation system include delivery (on farm) and installation costs. It includes water reservoir (3,000 l), pump for water transfer from the basin to the reservoir and construction of well for pump in the basin. The costs of the irrigation system does not include construction of the basin for collection of water (it was constructed earlier, by previous land user), but one can calculate the costs of such structure (basin: L - 15 m, W - 5 m, D - 4 m) under local conditions. Current estimate of costs for such construction in Živinice municipality is around 4,000 USD. The total length of drip system pipeline per ha for the presented technology is 6,000 m.
Under the concrete conditions, the land user handles land leased from the municipality. The land rental charges are not included in the costs of establishing or maintaining the technology since they are, in this case, favorable (103 USD/ha/year) and can vary considerably under other conditions.
