Understanding changes in soil organic C (SOC) and total soil N (TSN) is important for evaluating C fluxes and optimizing N management. We evaluated long-term SOC and TSN changes under dryland rotations for historical stubble-mulch (HSM) and graded te

Carbon and Nitrogen Conservation in Dryland Tillage and Cropping Systems

Autor: Ordie R. Jones, Harry H. Schomberg

Publikováno v: Soil Science Society of America Journal. 63:1359-1366

Soil C and N greatly influence long-term sustainability of agricultural systems. We hypothesized that cropping and tillage differentially influence dryland soil C and N characteristics in the Southern High Plains. A Pullman clay loam (fine, mixed, th

Publikováno v: Soil and Tillage Research. 47:207-218

Concern about soil organic matter losses as a result of cultivation has been voiced consistently since the early part of the 20th century. Scientists working in the US. Great Plains recognized that organic matter losses from an already small pool cou

Long-term tillage and cropping systems affect bulk density and penetration resistance of soil cropped to dryland wheat and grain sorghum

Autor: Paul W. Unger, Ordie R. Jones

Publikováno v: Soil and Tillage Research. 45:39-57

Stubble mulch tillage (SMT) and no-tillage (NT) are well adapted for dryland crops in the US Great Plains. Long-term use of NT, however, may impair soil physical conditions and crop yields, and, by inference, soil quality and production sustainabilit

Cropping and Tillage Systems for Dryland Grain Production in the Southern High Plains

Autor: Ordie R. Jones, Thomas W. Popham

Publikováno v: Agronomy Journal. 89:222-232

Low precipitation and high evaporative potential limit yields of dryland crops in the semiarid Southern High Plains. Improved residue management can reduce evaporation and improve water conservation. We compared no-tillage (NT) and stubble mulch (SM)

Tillage and cropping system effects on selected conditions of a soil cropped to grain sorghum for twelve years

Autor: Paul W. Unger, Ordie R. Jones, Getachew Alemu

Publikováno v: Communications in Soil Science and Plant Analysis. 28:63-71

Soil and water conserving practices must be used to sustain dryland crop production in semiarid regions. In this 1994 study, we evaluated the effects of different cropping system and tillage method treatments on surface residue cover, organic matter
