Δυναμική του φωσφόρου σε εδάφη Alfisols
2013The influence of land use in the agronomic and environmental behavior of inorganic and organic phosphorus forms were examined in two different soil categories of order Alfisols; cultivated soils with various levels of available phosphorus (high, moderate, low) and native soils (forest vegetation).

Characteristic Variations in Spectral Reflectance of Selected Eroded Alfisols
Soil Science Society of America Journal, 1984Abstract Soil cores taken at incremental depths from a Typic Hapludalf were examined to investigate the relationships among the chemical, physical, and spectral reflectance properties which occur as the proportion of various horizons change in the soil samples. Results of these studies were compared to soil samples taken from selected

Moisture Retention of Cultivated and Pastured Mollisols and Alfisols
Soil Science Society of America Journal, 1971Abstract Comparison of surface soil moisture characteristic curves for Mollisols and Alfisols under pasture and row‐crop cultivation revealed that below ⅓ bar suctions cultivated Mollisols retained 40% more water and cultivated Alfisols retained 25% more than corresponding pastured soils.

Nutrient uptake and crop productivity on Podzolic soils (Alfisols)
2001Various methods to assess crop demand for nutrients were studied. Application of optimal amounts of macro- and micronutrients significantly increased yields of potato, annual grasses, and clover. The effect of nutrient uptake on crop productivity was revealed.
