Ammonium Phosphates A Profile (World)
Ammonium phosphates, utilized as fertilizers, are the result of the reaction of phosphoric acid and ammonia. About 3% of Ammonium phosphate is used as animal feed and for industrial application and diammonium phosphate is used as phosphate fertilizer. The N-P-K ratio of 18-46-0 and good handling properties make it ideal for small and large-scale agriculture. The combination of 1,175 tons of phosphoric acid with 40% P2O5 and 0.23 tons of ammonia give a ton of DAP which mean that about one ton of sulphur is required. The phosphate sector is dominated by the DAP trade, affecting prices and production. The manufacture of DAP, which is used mainly in mass blending, involves the use of about 35-40 percent of the global production of phosacid. Over 40% of the DAP’s global production is sold across borders, beating ammonia. To get a ton of MAP or monoammonium phosphate,

The usual target of beneficiation process is 35% P2O5 from 28%. The use phosphate rock as fertilizer is limited, since the solubility of it in acidic soil is a deciding factor. The rock needs to undergo a mineralogical test to ascertain the suitability depending on its chemical composition and structure. The carbonate radical contributes to P2O5 reactivity when it is directly applied on the rock.
At times, partial acidulation or PAPR of the rock happens when the rock’s insoluble tricalcium phosphate is converted into a combination of citrate-soluble dicalcium phosphate and water-soluble monocalcium phosphate. The various acids used include carobonic, nitric, phosphoric, acetic, citric, hydrochloric and sulphuric acids. The degree of acidulation rests on elements such as the nature of acid, ratio of acid and rock, reaction time, temperature and ration of non-apatite and apatite

This is an experimental lab that tested if drinking water passes the United States maximum phosphate standard. The results of this lab can help the American who drink the water know if there are too much phosphate in the water. Each group made a Potassium phosphate dilution from a stock solution. The concentration of the solution that needed to made affected the amount of Potassium phosphate that was diluted. To create a calibration curve, each group used the different concentrated Potassium phosphate solutions in their test. The lab utilized a spectrophotometer to figure out the absorbance of the five different Potassium phosphate solution and the absorbance of an unknown concentration solution. The absorbance of the unknown solution was used
Investigating Factors Which Affect The Reaction Between Chalk and An Acid. Introduction: Chalk is just one of the many forms that calcium carbonate can take. It is made of the mineral remains of sea creatures from millions of years. ago.
In the week one lab, members of the class were to classify six unknown rocks into one of the three rock types: igneous, sedimentary, and metamorphic. We were then to use that knowledge, along with other features of the rocks, to determine the rock name. This paper will identify each of the six samples based off the observations of each sample in the lab. The paper will go on to discuss the main properties of igneous, sedimentary and metamorphic rock. This paper will conclude with a discussion on what classification of a rock is the most useful in determining the name of the rock.
Acid Mine Drainage For hundreds, even thousands of years, human beings have mined for metals and stones, and with the advent of greater technology as well as greater needs, the demands for these resources continue to grow. While these resources benefit our lives in many ways, the effects of mining can be detrimental, and one such effect is the topic of this essay, acid mine drainage (A.M.D.). The Causes of A.M.D. will be discussed, along with some of the physical and biological problems associated with it. Some prevention and remediation treatments will also be considered.
According to Srinivasan (2006) and, Gebber and Adamchuk (2010) the implementation of PA has been demonstrably successful in industrial farming because of its large-scale and commercial production emphasis, especially with high- value cash crops that receive large amounts of agrochemical inputs and enter markets with strong differentiation based on quality, such as viticulture and horticulture.

Phosphorus stimulates root growth, helps the plant set buds and flowers, improves vitality and increases seed size. It does this by helping transfer energy from one part of the plant to another. To absorb phosphorus, most plants require a soil pH of 6.5 to 6.8. Organic matter and the activity of soil organisms also increase the availability of phosphorus.

Since rocks and minerals are affected by hydrolysis then it means that acids can be produced creating carbonation. “ The internal surface of each unweathering rock is characterized as both a mass fractal and a surface fractal (Bazilevskaya).” Carbonation occurs when it rains which it naturally a little acidic due to (CO2), which is carbon dioxide, combines with (CaCo3) which is calcium carbonate. “Rain had a normal pH level 5.0-5.5, which alone is acidic enough to cause a chemical reaction (Andrew).” The acid from the rain and the chemical reaction of carbon dioxide and calcium carbonate is what causes the chemical weathering. The acid on the minerals covers the type of chemical solutions, which is basic than acidic ones. As it said in oxidation about the weathering process that is transformation of rock into soil through physical and chemical reaction with the process that effect CO2 cycle. So if CO2 is in carbonation and if oxidations for the weathering process it could mean that all of these three types of chemical weathering are fitting in as one helping with the water or oxygen as will as
Potting soil mixes are the most important factors for quality production of flowers in floriculture. It becomes farmer’s first preference these days because flowering crops provide higher returns than traditional crops and its marketing offers both small and large scale growers a way to increase the level of sustainability on their farms. Globally, more than 140 countries are involved in cultivation of floriculture corps (Anonymous, 2006).

They contain one or more of the essential growth nutrients such as nitrogen, phosphorus, and potassium and various others. Once it added to the soil, these nutrients fulfill the required demands of the plants and provide them the nutrients & helps them retain the lost nutrients. Generally chemical fertilizer which is rich content of major nutrients like Nitrogen, Phosphorus, and Potash which is required to growth of the plant body. Chemical fertilizers are manufactured by synthetic material. It is prepared artificially. Many artificial fertilizers contain acids, such as sulfuric acid and hydrochloric acid, which tend to increase the acidity of the soil, reduce the soil's beneficial organism population and interfere with plant
