摘要:Abstract(#br)Many biochars contain considerable amounts of plant nutrient elements in both water soluble and insoluble compounds but little is known of the rate of release of these elements to soil. This laboratory research incubated nine biochars produced from tropical plan...

摘要:Abstract(#br)Mechano-milling is a process where materials are ball-milled at high energy to induce chemical and physical reactions. This study investigated the effect of milling on the properties and agronomic effectiveness of six apatite rock phosphates (RP). The effects of mill...

摘要:Abstract(#br)Laboratory studies have shown that up to 70% reactive rock phosphate dissolves in three soil types found in the high rainfall (> 800 mm annual average) area of south-western Australia. Three field experiments were undertaken on these soils to compare reactive apatite...

摘要:Abstract(#br)Rock-forming minerals of igneous and metamorphic rocks contain most of the nutrients required by higher plants for growth and development. Ground rock fertilisers may provide a source of nutrients to depleted topsoils where bulk soil solutions are not in equilibrium ...

摘要:Abstract(#br)Bushfires are very common in Australia as seasonally arid conditions prevail and many Australian native plants are highly combustible. Soil is heated in bushfires but the effects of heating are poorly understood. Soil heated in an intense bushfire was collected from ...

摘要:Abstract(#br)We studied the impact of heating on minerals in a lateritic podzolic soil from Bakers Hill, Western Australia and consequent effects on phosphate availability and plant growth. This forest soil was heated at 250, 350 and 500 °C, which are temperatures attained b...

摘要:The presence of round quartz grains and small cobbles in surficial sands suggests that fluvial activity has been a significant contributor to the distribution pattern of sandy soils on the deeply weathered plateau of southwestern Australia. Areas of these sands often occur as fra...

摘要:Abstract(#br)The kinetics of Zn extraction by diethylenetriaminepentaacetic acid (DTPA) from the ≤ 2 mm fraction of 12 calcareous soils was investigated using surface soil (0–30 cm) samples. Soils were equilibrated with 0.005 M, DTPA solution for 0.25 to 192 h. Zero-, first-...

摘要:Abstract(#br)Thirty six soil clay samples from surface and subsurface horizons of 18 Thai upland Oxisols and Ultisols under a tropical monsoonal environment were characterized for chemical composition, mineralogy and K release to 0.3 M sodium tetraphenylboron (NaTPB) solutio...

摘要:Abstract(#br)An analysis of properties of red Oxisols on calcareous sedimentary rocks under different climatic regimes in Thailand was carried out to ascertain their similarities and differences. These soils are Kandiustox in Northeast Plateau and Kandiudox in Peninsular Tha...
