Land evaluation of agricultural<br />

potentials<br />

Based upon the soil data accumulated during the<br />

period 1970-1988, the <strong>Soil</strong> Science Institute in<br />

Tirana began in 1988 a Physical Land Evaluation<br />

Study for all the agricultural land of the country.<br />

The main soil characteristics used for this land<br />

evaluation exercise were soil depth, thickness of<br />

the humus horizon, organic matter content at 50cm<br />

depth, available phosphorus, texture, and available<br />

moisture content of the topsoil. <strong>Soil</strong> acidity,<br />

alkalinity, salinity and the presence of stones are<br />

main soil constraints in Albania. Relief is a<br />

determining factor for agriculture; therefore slope<br />

threshold values were an important part of the<br />

evaluation process. Finally, climate determined the<br />

ultimate value of the land. Socio-economic factors<br />

were not considered in this study.<br />

At the end of the study all the agricultural land was<br />

divided into ten classes. Land class 1 is the best for<br />

agriculture crops while class 10 is the worst.<br />

Integral parts of this study were the preparation of<br />

several land evaluation maps, which show the<br />

classes of land for each farm, district and the entire<br />

country. The western coastal field areas, occupying<br />

about 250,000ha, have been identified with the<br />

best land classes, which have good potential for<br />

intensive agriculture. Classes 1 to 4 occupy nearly<br />

75% of this area. Factors of soil formation,<br />

physical landscape and generally similar climatic<br />

conditions are the main factors influencing the<br />

high land values. Hilly areas occupy roughly<br />

220,000ha. These areas, along with the interior<br />

valleys, belong to a variety of land classes, though<br />

classes 4, 5 and 6 are dominant. The main reason<br />

for the decreasing land values in the hilly zone is<br />

slope. Mountain areas covering about 80,000ha<br />

include the lowest ranking land classes due to<br />

steep slopes and severe climatic conditions<br />

(Kaleshi et al., 1992).<br />

The most important soil constraints, such as<br />

salinity (about 10,000ha), textural class, soil depth,<br />

alkalinity (about 60,000ha) in the western coastal<br />

area, and acidity in about 70,000ha mostly in the<br />

north-eastern part of the country, were also<br />

identified. Possible interventions to mitigate the<br />

negative effects of these constraints may increase<br />

the land values by one or two classes.<br />

Land use assessment<br />

A first attempt to prepare maps for actual land use<br />

and potential land use planning was done by Zdruli<br />

(1997b). This was followed by two EU
