Forecasting olive crop yields based on long-term aerobiological data series and bioclimatic conditions for the southern Iberian Peninsula
partial least-squares regression pollen emission
2014/10/23
In the present study, bio-meteorological models for predicting olive-crop production in the southern Iberian Peninsula were developed. These covered a 16-year period: 1994-2009. The forecasting models...
Dynamics of Root Border Cells in Rhizosphere Soil of Zea mays L.:Crushed Cells during Root Penetration, Survival in Soil,and Long Term Soil Compaction Effect
Detached cells Maize Rhizosphere Root cap Sloughed root cap cells Soil compaction Soil mechanical impedance
2009/7/23
Plant roots release mucilage and root border cells (RBCs) into rhizosphere, which function as a complex at the root-soil interface. The dynamics of RBCs in rhizosphere soil, however, remains unknown. ...

Climatic changes observed historically need to be known accurately in order to understand the present climatic conditions and to estimate climatic changes to be occur in future. In studies to be done ...
Changes in pore size distribution and aggregate stability of two soils under long term tillage systems
tillage systems bulk density pore size distribution aggregate stability
2008/11/26
Tillage-induced changes in pore-size distribution and aggregate stability of two soils were investigated for 7 con- secutive years from 1994 to 2000. The three tillage treatments were used: convention...
Impact of the long-term straw supply on loess-derived soil structure
plant residues slaking soil structural properties organic matter
2008/11/26
Keeping plant residues on the field and incorporating them instead of removing or burning them, is a well-known practice in soil and water conservation. One of the objectives of this management is to...
