TRIANGULATION METHOD FOR COMPARATIVE SOIL - YIELD STUDIES

Reliable results can be produced by using the research triangulation method. Its application is illustrated with agroecology data from Bulgaria. In several agroecological, environmental and sociological studies it is convenient and necessary to compare results of multivariate analyses derived from different data on the same territory or derived from different analyses of the same data. An appropriate approach for such comparative studies is based on the so-called “Procrustes analysis”. Its application is illustrated in search of interrelations between crop yields and soil texture, and soil hydraulic properties.
