A research on effect of different types of blades used in soil rotary cultivator upon the blades physical characteristics of the soil

Abstract

In this study two different types of blades used in rotary cultivator have been tested on the soil. Research has been done on the physical effects of these blades upon the soil,their effects on the soil resistance of penetration the volume of weight, porosity of the soil,specific weight,percentage moisture in the soil, percentage of stickiness, percentage of distribution of dimension and pieces of soil and heir effects on the breaking up of the soil. In this research it was discovered that both types of blades can be used in preparing seeding and seedbeds, that they broke up and cultivated the soil very well, especially up to a depth of 20 cm, that they brought about no tightening of the soil, but loosen it, that they left behind in the soil nothing harmful to prevent the development of plants, seeding and saplings, that they had a good effect on the physical characteristics of the soil and no harmful Effects. On examining the two types of blades we can sec that the L-tpye blade, when tested had more effect on the breaking up of the soil, where as the smooth type less effect.
