    Amelioration of growth reduction of lowland rice caused by a temporary loss of soil-water saturation

    Decreases in nutrient availability after loss of soil-water saturation are significant constraints to productivity in lowland rainfed rice soils. The effectiveness of soil amendments like lime and straw in ame...

    Phosphorus nutrition of rice in relation to flooding and temporary loss of soil-water saturation in two lowland soils of Cambodia

    In the rainfed lowlands, temporary loss of soil-water saturation during crop growth is a common factor limiting rice (Oryza sativa L.) yield but its effects on phosphorus (P) availability are poorly understood...

    Nitrogen-induced boron deficiency in lucerne

    In a glasshouse experiment with a boron deficient soil the application of nitrogen was found to decrease the boron concentration and boron uptake by lucerne (Medicago sativa). Without added boron, nitrogen applic...

    The effects of metal ions on the root surface phosphatase activity of grasses differing in tolerance to serpentine soil

    Six grass species which differed in ability to grow on serpentine soils were assayed for root surface acid phosphatase activity in solutions of Ca, Mg, Ni, Cr III, Cr VI, and Zn at various concentrations. The ...
