Agricultural use of organic amendments: a historical perspective
Article Abstract:
History shows the value of recycling organic waste in agriculture. Agricultural research done in land-grant colleges since the 1862 reveals that the regular use of organic fertilizer is important in keeping soil fertile and productive and protects against erosion and the loss of soil nutrients from leaching and run-offs. Historically, agriculturalists from the time of 2000 BC have used farmyard manure, crop residues, sewage, ash and other organic materials as fertilizers to keep soils fertile and productive, and the ancient Greeks and Romans that developed modern agriculture made extensive use of organic resources.

Introduction: improving the sustainability of dryland farming systems
Article Abstract:
The irrigation problem in the Middle East can be tackled by developing efficient soil and water conservation methods, and implementing productive and sustainable cropping practices. Improvement in agriculture practices can be achieved by applying the optimum combinations of planting methods, pest control, fertility management, and soil and water conservation methods. Livestock production and crop management need to be integrated. The economic impacts of multidisciplinary agricultural systems research will have to be quantified.

Transition from conventional to alternative agriculture in Pakistan: the role of green manures in substituting for inorganic N fertilizers in a rice-wheat farming system
Article Abstract:
Pakistan depends on the importation of agricultural products since production is not keeping up with population growth. A study on how to increase production demonstrates that in regions where urea supergranules (USG) and farmyard manure (FYM) are costly or scarce, green manures can act as a cheep N source and will help small-scale farmers to record good yields in rice-wheat rotation. Rice growth, output and N-uptake is the maximum with USG and green manures (GM) plus prilled urea (PU).
