%0 Journal Article %T Impacts of technologies on physical properties of agronomic materials %A Hellebrand H. J. %J International Agrophysics %D 1998 %I %X . Different ways in which agricultural and other technologies can impact the physical properties of agronomic materials are discussed. Direct and indirect effects of these technologes are shown. The necessity of further research especially on the genetic engineering is proposed. %K agronomic materials %K technologies %K physical properties %U http://www.international-agrophysics.org/artykuly/international_agrophysics/IntAgr_1998_12_1_43.pdf
