Abstract:
... Phosphorus (P) is a critical nutrient for plant growth and makes up about 0.2% of a plant dry matter (Smith et al., 2011), but it is of the most difficult nutrients for plants to acquire. In soil, P may be present in a relatively large amount, but much of it is poorly available to plants due to its low mobility in the acid soil. Low pH, aluminium (Al) toxicity, and low phosphorus (P) often coexist ...

Determining how agricultural management practices affect soil phosphorus (P) over the winter may further our understanding of the soil P cycle under specific environmental conditions in eastern Canada. This study assessed changes over winter for soil P fractions and other selected chemical properties as affected by tillage and P fertilization. In 1992, a long-term corn (Zea mays L.) and soybean (G ...

Abstract:
... Supplying a large amount of NO3− in the subsurface can be a strategy to combat subsoil acidity under no-till systems. However, soil acidification caused by ammoniacal fertilizers can increase both aluminum toxicity and lime requirement. A field experiment was performed in the period from 2004 to 2012 in Parana State, Brazil, on a loamy, kaolinitic, thermic Typic Hapludox to evaluate the effects of ...
