Cultural practices which increase the amount of insect pressure can also increase the amount of lodging that occurs in the corn crop. Studies were therefore carried out, in the late cropping seasons ...
Effect of tillage tool geometry on soil structural stiffness
tool geometry soil stiffness and behaviour
2008/11/19
The concept of structural stiffness signifies the level of resistance a body of agricultural soil develops so as to withstand any form of further deformation from subsequent external loading.In order ...
Accuracy of determining mechanical properties of the stalk depends, to a large extent, on the accuracy of determining characteristics of the sample cross-sectional geometry. Accurate calculations are ...
