“…Latruffe et al (2005) researching Polish farms reached a similar conclusion, as did Thiele and Brodersen (1999) when analysing efficiency of farms in West and the former East Germany. Insufficient fertilisation of Estonian agricultural land has led to three clearly negative results: First, only around 40-50% of the real yield potential of cereals is currently being realised (Roostalu et al 2001); secondly, the nutrient balances of arable soils are predominantly negative (Astover et al 2006a) and thirdly, Estonia's farms produce the lowest average cereal yield (in studied farms on average 1.9-2.3 Mg ha -1 ) in the EU25 countries. This has caused negative selfsufficiency for cereals and endangers the national food supply.…”

“…The external economic environment can have a greater influence on a farm's efficiency than the internal organisation (Brada and King 1993) and farm inefficiencies of transitional economies have been explained as an effect of disordered market conditions (Mathijs et al 2000). Considering the low intensity of crop production practices in Estonia (Astover et al 2006a), it is highly unlikely that the excessive use of inputs like fertilisers and pesticides is the reason for inefficiency. Relatively small slack-input ratio for intermediate consumption (Fig.…”

The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia's transition to a market economy and during the accession period to the European Union (EU). The non-parametric method Data Envelopment Analysis (DEA) was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000-2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU's investment support schemes in new member states.

“…One third of the arable land in Estonia is affected by some kind of degradation (FAO 2000) and about 11% by soil compaction (van Lynden 2000). The area of Estonian arable land has decreased, since the re-establishment of the independence of Estonia in 1991, to 53% of the previous level (Astover et al 2006).…”

Effect of Cirsium arvense L. on soil physical properties and crop growth

The re-cultivation of abandoned areas creates weed control problems. The main problems in these areas are perennial weeds, such as Cirsium arvense L. but this perennial deep-rooted plant may have a beneficial effect on the physical properties of compacted soil. In order to study the effect of C. arvense's root system on soil properties, the field experiment and a survey of arable fields were conducted in Estonia. The soil bulk density and penetration resistance were measured from soils covered by C. arvense or spring barley (Hordeum vulgare L.) on compacted and un-compacted soil. The results showed significantly lower penetration resistance and bulk density underneath C. arvense than under barley in both the field experiment and a field survey on arable soils. The shoot mass of C. arvense was less affected than the shoot mass of barley by soil compaction and was caused by C. arvense's better ability to develop its root system in compacted soil. Wheat yield, on soils affected by C. arvense, was increased by 28% on loose soil and 37% on compacted soil. It may be concluded that in areas affected by deep-rooted weed species, such C. arvense, the soil's physical properties will improve at least in the first two years.
