Fertigation rate, leaching fraction, and growth of potted poinsettia
Journal of Plant Nutrition, 1996Single-pinched poinsettia (Euphorbia pulcherrima 'V-14 Glory') in 15-cm pots received constant fertigation with 50, 100, 200, and 300 mg.L -1 nitrogen (N) from a 20N-4.4 phosphorus (P)-16.6 potassium (K) fertilizer with a leaching fraction (LF) of 0, 0.2, or 0.4. Plants received 25 irrigations during the 13-week study.

Impact of Cooling Rate on the Mineralogy and Leaching Behaviour of Copper Slag
Avoiding and minimizing the leaching of heavy elements from non-ferrous metal slags is a precondition for their effective valorisation, where minimum requirements are regulated by standards and legislation of different local regions. Whilst most laboratory-scale studies on slag leaching have focused on factors such as slag bulk composition and solutionChen, Jeff, Jak, Evgueni

Mechanisms and Rates of Pesticide Leaching in Shallow Clayey Till
1993Field studies and groundwater monitoring in an orchard indicated that migration in fractures of the pesticides simazine and atrazine had occurred through more than 8 metres of clayey till in a period of less than ten years. Leaching experiments applying large intact till blocks sampled in the orchard showed rapid transport of water and pesticides in ...

Heterogeneous Rate Processes in the Leaching of Base Metal Sulfides
1984Fundamental rate processes in sulfide leaching are reviewed. Electrochemical reactions of importance in dissolution and solidstate conversion reactions are presented and emphasis is placed upon copper and lead sulfides. Parameters important in characterizing potential new hydrometallurgical processes using anodic and cathodic reactions are reviewed.

Leaching rates of heavy metal ions in forest soil
Water, Air, and Soil Pollution, 1978The leachability of Mn, Zn, Cd, Ni, V, Cu, Cr, and Pb was studied in two purely organic spruce forest soils: one control soil and one similar soil heavily polluted by Cu and Zn from a brass foundry in southern Sweden. Artificial rainwater, acidified to pH 4.2, 3.2, and 2.8 was used in the experiment.
