Studies on Non-puddling Rice Direct Seeding (Part 1)

Physical Property of Soil and Tillage Facility

Abstract

In order to prove the influences to soil when non-puddling rice direct seeding is adapted to rice cultivation in cold area, we investigated the soil characteristics of paddy field which are cultivated with non-puddling and puddling during four years. Non-puddling system is superior to puddling system in water retentivity, drainage, tillage facility and soil bearing capacity. Non-puddling is proved as the system which can make good soil preparation of seed bed efficiently in short term after thaw.
