Soil Management and Tillage
Soil is one of our most precious natural resources. Proper soil management is a key to sustainable agricultural production. Soil management involves six essential practices: proper amount and type of tillage, maintenance of soil organic matter, maintenance of a proper nutrient supply for plants, avoidance of soil contamination, maintenance of the correct soil acidity, and control of soil loss (...
متن کاملSoil Compaction and Soil Tillage – Studies in Agricultural Soil Mechanics
Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...
متن کاملSoil organic carbon and nitrogen in a Minnesota soil as related to tillage, residue and nitrogen management
Soil organic carbon (SOC) and nitrogen (N) are directly influenced by tillage, residue return and N fertilization management practices. Soil samples for SOC and N analyses, obtained from a 23-year field experiment, provided an assessment of nearequilibrium SOC and N conditions. Crops included corn (Zea mays L.) and soybean [Glycine max L. (Merrill)]. Treatments of conventional and conservation ...
متن کاملCorn-Residue Transformations into Root and Soil Carbon as Related to Nitrogen, Tillage, and Stover Management
Recent studies of SOC storage and turnover have employed 13C natural abundance ( 13C) as an in situ Soil organic carbon (SOC) is sensitive to management of tillage, marker of relic and recent SOC pools. Mass concentraresidue (stover) harvest, and N fertilization in corn (Zea mays L.), tions of SOC and the 13C signature are sufficient to but little is known about associated root biomass includin...
متن کاملLong-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil
A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...
