I just don't want to get to the point where I have to replace sand or live rock Would it make sense to get a phosban reactor so most of the phosphate binds to that and not the rock or sand Or calcium?

Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.
While Agrium's phosphate mine at Kapuskasing, Ont. provided an "excellent return on investment" since it opened, economically viable rock reserves at the mine are expected to be depleted soon, the company said. The Kapuskasing mine was set up in the late 1990s to replace phosphate rock Agrium previously imported from Togo.
The recent upward trend in the level of phosphate rock shipments is expected to continue. In fact, it is estimated, based on regional imbalances in phosphate supply/ demand and the knowledge of intra-area exchanges, that world seaborne trade in phosphate rock will increase to some 58 million tons by 1980, and 72 million tons by 1985.
Phosphate mining began in Florida in 1883 near Hawthorne in Alachua County. This hard-rock phosphate was mined in a region extending from Alachua to Citrus counties. The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County.
Ahead of the publication of the 2017 Phosphate Rock Cost Report, CRU undertook a research visit to Egypt's largest mine, Abu Tartour, as the mine's operator, Misr Phosphate Co., plans to construct its first phosphoric acid plant at the site. Egyptian phosphate rock is low cost but also low value. Downstream facilities in Egypt remain modest ...
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening ...
rock, so we used abotartor phosphate rock 22% and tried some additives like Illite Clay rock by mixing it with phosphate rock at different ratios and was detected from XRF analysis the addition of essential elements for the plant as potassium .

Phosphate rock is a non-renewable resource that has taken 10-15 million years to form from seabed to soil via tectonic uplift and weathering. Many recent studies indicate that phosphorus demand could outstrip supply this century if no fundamental changes are made to the current trajectory, while others argue we have 'hundreds' of years ...
Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs ...
Soft rock phosphate, also called CalPhos or colloidal phosphate, is a great source of potassium and calcium for your plants. Our CalPhos comes from phosphate rock mined in Florida, which was formed millions of years ago from the mineralized remains of marine creatures. Soft Rock Phosphate should not be confused with Hard Rock Phosphate.
Phosphate rock fertilization is commonly used in peatland restoration to promote the growth of Polytrichum strictum, a nurse plant which aids the establishment of Sphagnum mosses. The present study tested whether 1) phosphorus fertilization facilitates the germination of P. strictum spores and 2) biochar derived from local pig manure can replace imported phosphate rock currently used in ...

12%Minjingu phosphate rock (MPR) The Minjingu phosphate deposit is located in the Eastern Rift Valey in northeastern Tanzania (Fig. 1), near Lake Manyara around the footslopes of a small inselberg that served as resting/nesting place for a large colony sometimes during Pleistocene (Szilas 2002).The deposit consists of locally so-called hard and soft MPR.
method has been successfully applied to phosphate rock, superphosphate, "meta phosphate", and liquids used with silicate cements in dentistry. It is recom mended for use in standardization and umpire analyses of phosphate rocks and similar materials, but it is not sufficiently rapid to replace …
The only U.S. producer of elemental phosphorus received approval for a new phosphate rock mine in Idaho. The new mine would replace the current mine when the ore is depleted in about 10 years. U.S. phosphate rock annual mine production capacity was expected to remain at 31.1 million tons in 2020.

All-Natural Phosphate Replacement. Innovation thrives when you find the intersection of a market need and a solution for that need. In some instances, the process is organic and comes through inspiration. More common is the situation where a need is uncovered and then extensive research is conducted to discover the solution.
Oral Phosphate Replacement. Oral repletion is most often achieved with a combined preparation of sodium and potassium phosphate. E.g. Phos NaK 250-500 mg 1 tab four times a day with meals and at bedtime. K-Phos 1-2 tabs PO QID. 1 tab of K-phos = 250 mg phosphorus, 8 mmol phosphate, 1.1 mEq potassium, 13 mEq sodium. ...
Florida has more than 14 million ha of acidic soils and most of these acidic soils are very sandy. Transport of phosphorus from these soils to surface water is a great concern in Florida. One of the promising approaches is to develop slow release P fertilizers to replace the regular water soluble fertilizers. Dolomite phosphate rock (DPR) is an ideal material for making this type of fertilizer ...
Phosphate rocks are by far the most important phosphorus-bearing raw material used in the fertilizer industry. They are the primary source of phosphorus (P), which is an essential element for agriculture and various industrial applications (e.g., animal feed, cosmetics, and electronics) [1,2].Phosphate rocks are also likely to host significant amounts of rare earth elements (REE), making them ...
S. Sedimentary rock phosphate, I. Igneous phosphate, nd. no data. Radioactivity elements in phosphate rock The radioactivity of phosphate rock was probably first observed in 1908, when the British physicist R. Strutt found that samples of phosphorite were many times more radioactive than the average ). (()
According to Robert Vanderslice, head of Phosphate Management for Florida's Department of Environmental Protection, the gypsum is a "good material to replace lime rock in roads. Lime rock will run out at some time, and we're still building a lot of roads. Building roads with phosphogypsum would consume quite a bit of gypsum."
Phosphate fertilizers may become more scarce and expensive in the future, so consider using alternatives, such as cover crops and animal manures, to boost low phosphorous soils. Edible gardeners know that phosphorous is a key nutrient for vegetable, fruit, and berry production. Phosphorous is essential for root crops such as beets, carrots, and ...
Rock phosphate is found in all continents of the world (figure 1). It is used as a raw material in the manufacture of inorganic phosphorus fertilizers and can be used as organic phosphorus fertilizers when applied directly to the soil. Direct application of rock phosphate increases crop yield and soil phosphorus levels (1, 2,3).
The use of natural adsorbent such as phosphate rock to replace expensive imported synthetic adsorbent is particularly appropriate for developing countries such as Tunisia.

The top phosphate-producing states, Florida and North Carolina, accounted for over 75% of domestic output. The other 25% of US production came from Southeast Idaho and Utah. The majority of the phosphate rock mined in the US is used for manufacturing phosphoric acid and …
