TESTING THE SHAPE-SIMILARITY HYPOTHESIS BETWEEN PARTICLE-SIZE DISTRIBUTION AND WATER RETENTION FOR SICILIAN SOILS

Testing the shape-similarity hypothesis between particle-size distribution and water retention for Sicilian soils

Application of the Arya and Paris (AP) model to estimate the soil water retention curve requires a detailed description of the particlesize distribution (PSD) but limited experimental PSD data are generally determined by the click here conventional sieve-hydrometer (SH) method.Detailed PSDs can be obtained by fitting a continuous model to SH data o

Annual Ryegrass (Lolium rigidum), Wild Oats (Avena spp.) and Sowthistle (Sonchus oleraceus) Are the Most Commonly Occurring Weeds in New South Wales Cropping Fields

Weeds are a major impediment to crop and pasture production and profitability in Australian farming systems, and knowledge of their occurrence is vital in devising weed management solutions.This study examined the relationships between weed and crop species from observations made during surveys of randomly selected fields in grain vibrating table f
