Effects of cutting frequency of tall fescue on cadmium

Aug 02,  · Cutting is a common practice for turfgrass culture and maintenance, and it may affect cadmium (Cd) uptake and enrichment due to the removal and regrowth of aboveground parts. The objective of this study was to determine how cutting frequency affects Cd form in the soil and its enrichment and distribution in clippings, stubble and roots.

Feb 27,  · Cadmium (Cd) is a toxic heavy metal and is also known as one of the major environmental pollutants. Moderate Cd contamination of arable soils can result in considerable Cd accumulation in edible parts of crops (Arao and Ae 2003; Arao et al. 2003; Wolnik et al. 1983).Such levels of Cd in plants are not toxic to crops but can contribute to substantial Cd dietary intake by humans (Wagner 1993).

Calcium deficiency in plants is best treated by ensuring soil has a neutral or near neutral pH and that the moisture level in the soil is consistent. Calcium is most available between pH 7.5 and 9 but good uptake should still occur between pH 6.5 and 9.5 and so you should add either lime or sulfur (or another acidifying or alkalising agent) if
