Information about ground conditions of work is necessary for determination of the numerical values of the technological parameters of the new machines. The condition of the field and ground to be sowed as well as the obtained result of the machine work are evaluated in relation to the production tasks to be solved. The most precies evaluation of the condition is the quantity one. It is made through the values of quantities which represent particular aspects of the surface structure of the field and ground, connected with the tasks to be solved. It is custom these quantityes to be called characteristics of the given condition. Then dispersion, correlational function and spectral density of the random function are basic characteristics of the field microrelief.
