To improve our ability to predict SOC mineralization response to residue and N additions in soils with different inherent and dynamic organic matter properties, a 330-day incubation was conducted using samples from two long-term experiments (clay loam Mollisols in Iowa [IAsoil] and silt loam Ultisols in Maryland [MDsoil]) comparing conventional grain systems (Conv) amended with inorganic fertil...

Biomass crops are being promoted as environmentally favorable alternatives to fossil fuels or ethanol production from maize (Zea mays L.), particularly across the Corn Belt of the United States. However, there are few if any empirical studies on inorganic N leaching losses from perennial grasses that are harvested on an annual basis, nor has there been empirical evaluation of the hydrologic con...

The persistence and efficacy of acetamide herbicides at application timings from fall to preemergence (PRE) were studied in 1998 and 1999 on mollisols (1.1 to 2.8% organic carbon). Metolachlor, s-metolachlor, acetochlor (as an emulsifiable concentrate [EC] formulation and two encapsulated formulations, capsule suspension [CS] and microencapsulated [ME]), and the combination of flufenacet 1 metr...

Returning residue to soils is not only an effective nutrient management method, but also can reduce the air pollution caused by burning, which has become important factor in global warming. However, it clear whether returning soil affect nitrogen mineralization and cycle process, environmental impact loss gaseous forms. Therefore, a pot experiment was conducted study effects of placement on tur...

In the northeast plains of China, intensive utilization agricultural soils has been a persistent issue, and finding ways to utilize soil resources efficiently sustainably through scientifically-driven management system become crucial challenge for production. Conservation tillage is technology sustainable agriculture. Currently, plow rotary are dominant methods used in Mollisols, but there limi...
