Influence of technology of basic soil processing on chosen specifications in the process of growing flint maize (Zea mays L.)
 ŠIMEK, Roman
The diploma thesis is divided in two elementary parts. Current state and factors influencing soil fertility and its degradation are described in the literary part. An experiment, focused on comparison of two systems of starting the cover considering the period (spring, autumn) of realization of basic soil processing, is described in the practical part based on the methods. The influence of used technology of soil processing on its compaction was evaluated based on gauging the penetrometric resistance and on the evaluation of taken unimpaired soil samples. The values from the penetrometric gauging show that higher values were recorded at autumn dung ploughing in, compared to spring period. Higher values of the penetrometric resistance were gauged at headlands too. The difference in rail lines compaction compared to the field is dependent on the number of taken measures during the plant vegetation period and the measuring showed the compaction of lower soil layers. The values calculated from taken unimpaired soil samples show that the values of reduced mass per volume confirm the results of the penetrometric gauging. The values of maximum capillary water capacity characterize the soil at chosen stands as ?moisture-holding? and higher values were found out when using minimization technologies of soil processing. When comparing the period of soil processing, it was further established, that higher yield was when using the autumn dung ploughing and at the land with the autumn ploughing was also measured higher growth and weight of monitored corn, than at a land with work technologies done in the spring
