What Makes A Fertiliser?

Sand is the largest particle and doesn’t stick together very well. Sand particles create large spaces that allow water to flow through very quickly. Sand is also very gritty to the touch. Silt is slightly more dense and sticks together a bit more than sand does. Silt is also the second biggest particle. Silt has slighter better water holding ability and feels like flour when dry and smooth when moist.Clay is the smallest particle, and is very dense. Clay sticks together and can be molded and formed. Clay has the ability to hold nutrients and water in. Clay also has very poor water drainage. Clay is clumpy and chalky when dry, and sticky when wet.

It is also affordability, convenience, and effectiveness in nourishing plants; however it can also have disadvantages when using chemical based fertilizers. Plants will show signs of lacking nutrient the inorganic fertilizer was separate help over organic choices, it depends on soil organisms to first, break down the organic substance before the nutrients can be out. Inorganic fertilizer’s fast delivery elements and minerals eliminate this potential problem. Inorganic fertilizer, which is often reasonably priced, consists of mineral-based nutrients manufactured for instant application on crops. Unlike the organic variety, inorganic fertilizer does not need to decompose over time to supply nutrients to plants. Inorganic fertilizer contained balanced amounts of nitrogen, potassium and phosphorus to supply plants and to grow it faster. These are the substance of chemical gain from the processes in cultivating the first one is urea. Nitrogen as urea can be lost to the atmosphere if fertilizer urea remains on the soil surface for total periods of time throughout warm

When the crude product is transferred to a separatory funnel, it is washed with 10 ml of water. When the solution forms two layers, the bottom aqueous layer is disposed of.

Discard the solution in the appropriate container as directed to you by your lab instructor.

It could also be an isotonic solution. This is when the concentration (or molarity) of the cell is identical with the concentration of the solution. In this case the cell (or potato core) stays the same in size, which is called flaccid. No water moves either in or out of the cell.

When these components are mixed with the water, this causes the tiny particles of soil to stick together or coagulate. These particles are now bigger and heavier, they are known as flocs which makes it easier to remove by settings of filtration.

Human activities such as the use of fertilizers in yard soil contribute to the accumulation of nutrients. When using fertilizers, the ground can only absorb so much. The use of excess fertilizers on crops allows for nitrogen to vaporize in the atmosphere through a process called volatilization (Olascoaga, 2010). Crop fertilizer also leaches nitrogen into groundwater, which eventually ends up in the ocean. When the ground is at its maximum absorbance, high concentration levels are obtained and carried through the waste system into rivers. Another factor is sewage from the increasing human population. Septic tanks are widely used unless a household is connected to wastewater treatment plants. Septic tanks purify waste by leaching the waste through soil. Storm water runoff is another source of nutrient for algal blooms. Rainfall picks up nutrients from yards and flushes these nutrients into

The pipette was used to transfer 8 mL of the 0.5 molarity solution into the graduated cylinder. Distilled water was added to raise the bottom of the meniscus to the 20.0 mL line and the solution was transferred into the beaker after it was rinsed with the solution. The pipette was used to take a small quantity of the solution and rinse and then fill a test tube with the solution. The amount of 0.2 molarity solution needed to create 20.0 mL of 0.1 molarity solution was calculated as 10.0 mL. The pipette was used to transfer 10.0 mL of 0.2 molarity solution into the graduated cylinder and distilled water added until the bottom of the meniscus reached the 20.0 mL line. The solution was transferred to the rinsed beaker and then a portion placed into a test tube that had been rinsed with the solution. The amount of 0.1 molarity solution required to create 20.0 mL of 0.05 molarity solution was calculated to be 10.0 mL. The pipette was used to transfer 10.0 mL of 0.2 molarity solution into the graduated cylinder and distilled water added until the bottom of the meniscus reached the 20.0 mL line. The solution was then placed into a beaker that had been rinsed with the solution and then into a rinsed test

Then phosphate buffered saline (PBS) is added which will allow the mixture to pass through the

Expectedly, the soil and a variety of dense particles settled to the bottom of the test tube. Using a pipette we drew water from the center of the sample, but making sure not to draw up any soil. Three separate slides were prepared, each

b) If 5mL of water were added for every 1g of crude product then one of two things would happen; the solid would not dissolve or the impurities would still be present within the product. The solvent is used to dissolve all the impurities of the crude product and if less solvent is available, the impurities would remain within the product.

injected into the ground and leak into the water systems, making it impure and unsafe to drink.

precipitate; then pour over the solid in the funnel. Finally, pour two 10-mL portions of

The black precipitate was allowed to settle and then the supernatant, the clear liquid that lies above a precipitate, was decanted, or poured carefully off. Then, 200 mL of hot distilled water was added and the precipitate was allowed to settle to repeat the decanting process again.

Thirdly, the proceeding water treatment step involves coagulation and flocculation. The objective of this step is to produce particles of a size that can be easily removed by settlement and filtration. Coagulation destabilizes the colloidal particles followed by flocculation whereby larger particles are formed from small particles through collisions. Conley and Evers (as cited in Hendricks, 2006, p. 277) described coagulation as a process that reduces the surface charge
