Tillage affects the soil properties and crop yields |
| Material Type: |
printed text |

T Karki, Author ; Shrestha, J., Author |
| Pagination: |
432-438 p. |

Conservation tillage, soil properties, yields. |
| Abstract: |
With the aim of consolidating the information of soil tillage and its effect on soil properties and crop yields, a brief review of the works being done within and outside the country was carried out. The review revealed that conventional agriculture system with intensive tillage practices deteriorated the soil quality and affected the crop yields. Tillage decreased the soil organic carbon, the crucial store house of soil-plant system and the major nutrient nitrogen over longer run. Conservation tillage (CT) also called the minimum or no tillage where soil is covered with crop residue, significantly improved the physical, chemical and biological properties of soil. CT increased the soil aggregates of more than 2 mm by 134%, increased water availability by 36-45 %, and porosity. Similarly, higher thermal conductivity in CT soils produced the lower increase in soil temperature in the upper soil profile. In CT, soil pH was higher in surface but lower in sub surface…………………. |
