Abstract:

Master of Science<br>Department of Agronomy<br>Ganga M. Hettiarachchi<br>Human activities have the potential to alter soil biochemical properties in a number of different ways. This thesis will focus on how agricultural practices (tillage and cropping system), climate change, and urban soil pollution (primarily lead and arsenic) affect soil biochemical properties. Two incubation studies were conducted to determine how human activities influence soil biochemical properties. The first study focused on how altered temperature and moisture regimes affected soil properties from four different agroe

Abstract:

Alternative fertilizers are commonly promoted for use on pastures to improve productivity and support a more ‘healthy’ soil microbial environment. However, minimal field research has been conducted to validate such claims. A 6-year study (2009–14) was conducted on phosphorus (P) deficient soils at three sites near Yass, NSW, to investigate the effect of top-dressing native perennial grass-based pastures with a range of alternative fertilizers and with single superphosphate (SSP). The alternative fertilizers included manures, composts, concentrated ash, crushed rock, rock phosphate-derived and

Most of the microorganisms on Earth are found in sophisticated colonies called biofilms.

Particularly, in porous media, a sound characterization of the microbial dynamics is key for the design and management of many technological applications. Literature c
