Abstract

Fertilizing and spraying techniques are repeatedly driven in tramlines for crop care with products whose demand increases for higher yields. The soil in tramlines is so compacted by heavy crop care machinery what leads breakdown to lifelessness. Such damaged state of the soil continues all season and leads to dejected soil productivity. The aim of this study is to find an optimal process of soil renovation in tramlines on loam and clay loam soil and to determine the required fuel consumption. The soil renovation was investigated by specially made Tiller on the dependence of tine shape types (narrow and winged) and working speed 1.6, 2.2 and 3.6 m∙s−1 in loam and clay loam soil. The beneficial relationships of soil aggregate fraction ratio, which varied from 0.54 to 4.08 and fuel consumption, which varied from 1.04 to 1.82 L·km−1 independence on tine shape and soil type was established. Based on research results, the sufficient soil loosening to suitable proportion of soil aggregates fraction ratio on loam soil was accomplished at working speed 3.6 m∙s−1 with winged tine type and fuel consumption was 1.04 L·km−1. The suitable soil aggregate fraction ratio on clay loam was achieved at working speed 3.6 m∙s−1 with narrow tine shape type and fuel consumption was 1.31 L·km−1. The volume of loosed soil in tramlines was particularly influenced by variation of tines shapes but was not influenced by the working speed majorly. The aligning of soil surface was influenced by the working speed majorly and particularly by variation of tines shapes.

Summary

Introduction

The farmlands size has tendency to increase, machinery designed more productive, at the same time more massive, increasing the negative soil compaction [1]. The tramlines for crop care are formed by seeding machines, into this line’s seeds are not sown, the fertilization and spraying techniques are repeatedly driven with products whose demand increases for higher yields. The degree of soil compaction during field traffic depends largely on the soil water content [4]. It changes soil properties: increasing bulk density, soil penetration resistance and decreasing porosity, rainwater infiltration and aeration [5]. A lot of studies covering a range of different soil types have reported significant compaction effects on structural conditions to deep subsoil layers [6,7,8,9].
