Some theoretical problems connected with requirements for consumer and environment protection of soil tillage
1995
Nugis, E.
The investigations were carried out in lighter, medium and hard soils. For new soil tillage implement the optimum value of parameters was worked out. These parameters are following: bulk density (gxcm (-3)), penetration resistance (MPa) and coefficient of soil trample (kN/m (3)). The analysis demonstrate that traffic intensity (Txkm/ha) and energy consumption (MJ/ha) for several field operations concerning soil tillage depend on the hardness of soil and show that while using technology as a complete seedbed preparation as a part, the above mentioned criteria are lesser than while using the conventional tillage technology. Summarizing the results of our investigations the effects of limit the adverse impact of the running gear of heavy machinery and improper tools on soil are shown. With regard to this the agroecological requirements could be handy to use to those engaged in designing and manufacturing agricultural implements as well as to individual farmers
