Steel slag has been widely used as amendment and silicon fertilizer to alleviate the mobility and bioavailability of heavy metals in soil. The objective of this study was to evaluate the influence of particle size, composition, and application rate of slag on metal immobilization in acidic soil, metals uptake by rice and rice growth. The results …

Coal gasification fine slag (CGFS) is a kind of industrial waste that is generated from entrained-flow coal gasification with a high content of 0.5 M hydrochloric acid (HCl)-extractable silicon (Si).

ABSTRACT A silicon–potash (Si–K) fertilizer was synthesized from magnesium slag (Ms), which is an industrial residue generated from the refining process of magnesium and magnesium alloy. Nutrient release characteristic and the effect of Si–K fertilizer on soil fertility and agronomic performance were evaluated so that an …

The paper presents the basic characteristics of slag, analyses and its modification by incorporating some essential plant nutrients and the possibility of its application as fertilizer was studied.

Tomato food guaranteed analysis label. All commercially available fertilizers have what is called a guaranteed analysis, meaning the percent of each major nutrient, by weight, in the fertilizer must be listed on the package as N-P-K. . For example, 10 pounds of 17-18-28 tomato food fertilizer contains 1.7 pounds of nitrogen, 1.8 pounds of phosphorus oxide …

However, plants fertilized with slag and inoculated with A. citrulli produced significantly equal NF to fertilized plants that had not been inoculated. When inoculated, non-fertilized plants had a 22% decrease in fruit production. Fruit harvested from slag-fertilized plants showed higher FTh (7%) and SS (8%), regardless of hybrid and if inoculated.

In view of the high content of silica in fly ash and abundant heat in blast furnace slag, high efficiency silicon fertilizer was prepared by mixing blast furnace slag with fly ash directly. When the fly ash and blast furnace slag were mixed with a mass ratio of 7.76:92.24, the effective silicon content in silicon fertilizer was highest after the condition of quenching.

On the other hand, steel slag has the potential to contribute to soil fertility and thus to crop yield as it has a significant amount and variety of essential plants. Steel slag can be used directly as a fertilizer, or it can be used more effectively by mixing and preparing compost with vegetable and animal wastes (Reuter et al. 2004; Winkler ...

For flowering or fruiting plants, a fertilizer with a high phosphorus content is often better, and for targeting leafy growth (like on a lawn), a fertilizer with mostly nitrogen is the best choice. Fast Facts. A fertilizer with high numbers isn't necessarily better than a fertilizer with low numbers, and vice versa.

Application of steel slag reduced soil acidity, increased plant–availability of silicon, promoted rice growth and inhibited Cd transport to rice grain in the soil-plant system. Expand 78
