Long-Term Effects of Tillage on Physicochemical Properties of Modified Andisol of Northeast Honshu Island

Abstract: Many reports suggest that tillage practices affect crop growth by altering soil properties. However, there is a paucity of information on long-term effects of tillage practices on the properties of modified Andisol in colder region. This study compared the effects of zero tillage (NT g ) with continuous fodder crop, zero tillage (NT a ) with continuous orchard, conventional tillage (CT) with sweet potato and corn (in summer), and wheat, barley, rye and colza (in winter), and puddling (P) with continuous rice o… Show more

“…Soil hardness under PD (7.45 kg cm À2 ) was significantly greater than under NT (5.25 kg cm À2 ) and CT (1.88 kg cm À2 ) ( Table 4). Rahman et al (2003) observed that soils under PD treatment have significantly higher soil hardness than soils under NT and CT. They also observed the significant variations in soil hardness at different matric suction.…”

“…But in site-2, the C content of topsoil was found lower (0.42%) than subsoil (0.65%). The content of C is high where tillage practice is minimum (Rahman et al, 2003). The high content of organic C is due to the application of organic matter for the production of rice and other crops.…”

“…Roldán et al (2005) also reported no changes in soil pH and EC in both no-tillage and CT systems after 6 years in clay Vertisol. However, Rahman et al (2003) found lower pH and EC after 15 years in a no-tillage system than in CT on a sandy clay pumic Andisol.…”
