Single super phosphate ...

Current advances in the technology of basic slag production include methods of granulation to avoid the dust problem associated with the normal powder product, magnetic beneficiation to yield an enriched …

On the contrary, soil enrichment with 20 g/kg of slag (D2) resulted in the reduction of plant biomass (a reduction of 20% and 40% of shoot and dry weights, respectively) and presented the highest ...

Slag is used as a soil amendment due to its high. Ca and Mg content, and on the other hand, it is used directly as a ra w material for the production of silicon. fertilizer or phosphorus ...

Since you are just starting out, I suggest using Seachem Flourish Comprehensive as your fert and Seachem Excel as a source of carbon if you are not currently doing CO2. I started using both and had good results. Eventually I added DIY CO2, which opened my eyes to the benefits of CO2, and evolved from there.

Four kinds of slow release fertilizers were prepared out by coating common compound fertilizer [nitrogen (N)-phosphorus pentoxide (P2O5)-potassum oxide (K2O):15-15-15] with four kinds of superfine phosphate rock powder (SPRP) which accounting for 60% of the total coated materials in mass. Electronic microscope scanning, static water …

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 …

For a modern agricultural, the search for sustainable practices to increase productivity is fundamental. Steel slag have been studied for their potential use in agriculture. These substances present a great possibility of agricultural applications since they are rich in nutrients, which enhance plant uptake. In this regard, the effect of steel …

Slag-type fertilizer, which is a byproduct of the steel industry, contains high amount of active iron oxide and silica. This byproduct acts as an oxidizing agent in the agricultural soils and may have positive impact on the soil properties and plant growth. It can suppress CH4 emission, while may also affect N2O emission. A pot experiment with …

Therefore, as a Si-K fertilizer, magnesium slag-based fertilizer was effective to alleviate the toxic effect of HMs on plant physiological process. In addition, Some plants also chelated metals with organic molecules (e.g. proteins and amino acids), thereby transforming heavy metal-induced reactive oxygen species into less-toxic products ( …
