Nitrogen fixation

Phosphorus is an essential nutrient to all forms of life and is required for building DNA, RNA and amino acids (Paytan, 2011). Phosphorus is often a limiting nutrient in ecosystems, along with nitrogen, and therefore its abundance determines the amount of primary production that can occur within a system (Schindler, 1971). The two main types of phosphorus are inorganic phosphate minerals, such as calcium phosphate rock that is mined for fertilizer, and organic compounds containing phosphorus…

What kind of soil structure that supports the growth of garden landscaping? The structure of the soil fertile and flat is coveted for each kind of garden landscaping. But for those of you that have outdoor areas like slopes, how to make garden landscaping? What is the area of hillside garden landscaping can be made? Of course it can, although the contours of the land are like that, you can still create a garden or often called the hillside landscaping. But when you happen to have to make the…

agricultural research shows that deliberately increasing SOC raises the health and amount of food produced of crops and improves pastureland for grazing livestock. Decomposition of plant and animal material in the soil also releases other nutrients such as nitrogen and phosphates, which are vital for plant growth. SOC also changes the overall soil composition it increases the amount of water that can be absorbed and stored, improves gas exchange, and breaks up the soil, making it easier for…

Phlogiston theory The phlogiston theory states that the every combustible substance on this planet contains phlogiston. When a combustible substance is burned, phlogiston is released into the air. The people behind the phlogiston theory believed that the whenever a substance sets on fire, the fire gives off phlogiston. The phlogiston was believed be the kind of gas which causes fire. Without phlogiston, the combustible substance won’t be able to set on fire. In the late 1660’s a scientist…

The invention of gunpowder was drastic and life altering discovery. Gunpowder was discovered in Ancient China in the 9th Century during the Han dynasty, by an alchemist named Wei Boyang (A&E). Boyang was one of the many alchemists hired by the government to create an exlir that would satisfy the emperor’s search for immortality. Through his research he accidentally came across gunpowder. The alchemists “experimented with the Sulphur, common charcoal, and saltpeter heating the substances in order…

Bud bank dynamics (Benson, Hartnett et al. 2004) study suggest that the densities and dynamics of tallgrass prairie plant populations, as well as their response to disturbance (e.g., fire and grazing) and climatic variability, may be mediated principally through effects on the demography of belowground bud populations. Patterns of seed reproduction and seed bank populations have little influence on short-term aboveground population dynamics of tallgrass prairie perennials. Our results indicate…

Fertilizer is a key variable in growing nice and healthy plants for your garden. You don't want to give to little or too much fertilizer to your plants, because then your plants won't grow so good. To prove this I took five plants and used Miracle Gro 3x fertilizer and used eighty to two hundred and twenty five milliliters of fertilizer. The steps i took for this experiment was pretty simple i filled the containers with soil and tomato seeds. Then I used measuring cups for the fertilizer…

Beginning Question: How effectively and efficiently can biphenyl be synthesized by a Suzuki coupling reaction? Claims: Biphenyl synthesized by a Suzuki coupling reaction was effectively isolated and then characterized using TLC, melting point, IR and 1H NMR tests. However, this process was not efficient because it had a poor pure yield of 22%. Evidence: The goal of the experiment was to synthesize biphenyl product by a Microwave-assisted Suzuki reaction and this was carried out using 1…

Can Fireworks Explode without Being Lit? Fireworks exploding on the night sky is a majestic sight. These explosives look stunning but they are still just that, explosives. In order to enjoy them, you want to keep in mind the safety rules and follow instructions. But could something go wrong? Can fireworks explode without being lit? How do fireworks work? Fireworks come in different types from rockets to wheels. But each firework will have a fuse, which is the main part of the firework in…

Benton Smith April 26th, 2018 PES 4520 Improving a Poor Lawn Soil Soil fertility is the foundation for healthy grass. Improving soil quality can be more challenging on an established lawn rather than growing a new one. The most important thing for soil is air and water and their ability to be absorbed by the roots. This helps nutrients to be absorbed also. A degraded soil typically loses its ability to supply food and habitation to living organisms, in it’s surrounding. Characteristics of a…
