Crop Performance and Soil Properties under Organic Nutrient Management

Crop management effect on chemical and biological properties of soil

This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3...

GRDC Project No CSO 00029 Residue Management, Soil Organic Carbon and Crop Performance - Functions of Soil Organic Matter and the Effect on Soil Properties

Corn yield and yield stability under varying nutrient management, crop rotation, and rainfall

Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...

Crop residue management and fertilization effects on soil organic matter and associated biological properties.

Returning crop residue may result in nutrient reduction in soil in the first few years. A two-year field experiment was conducted to assess whether this negative effect is alleviated by improved crop residue management (CRM). Nine treatments (3 CRM and 3 N fertilizer rates) were used. The CRM treatments were (1) R0: 100 % of the N using mineral fertilizer with no crop residues return; (2) R: cr...

Soil and crop management under conservation agriculture in Zimbabwe

Carbon mitigation strategies and mechanisms have been globally implemented in an attempt to prevent catastrophic climate change. Kyoto targets require reductions in greenhouse gas emissions and increases in carbon sequestration. Although a number of carbon neutral technologies have been adopted such as bio-fuel and alternative energies, these currently fail to meet global requirements. An innov...
