Method for Minimizing the Adverse Effect of Soil Crusts on Seedling Emergence (Part 1)

Development of Soil Covering Device and its Field Performance

Abstract

The purpose of this study is to develop a method for minimizing the bad effect of soil crusts on seedling emergence in the field. The author has developed a method of preventing the formation of soil crusts by covering seeds with materials which will not form soil crusts. In this paper, a soil covering device attatched to a seeder was made and seedling emergence tests were carried out in a clay field. It was proved that soil crusts were scarcely on the surface of seeds, and the field emergence rate of onion covered with pumiceous sand increased remarkably.
