Differences And Effects Of Natural And Synthetic Fertilizers

680 words - 3 pages

At the core of the growth and germination of plants lie the nutrients they receive from the soil. The nutrients required for growth are classified into two groupings, macronutirents and micronutrients. Macronutrients are those that are needed in very large amounts, and whose absence can do a great harm to the development of the plant life. These nutrients include calcium, nitrogen, phosphorus, and potassium, and are very sparse in most soils, making them the primary ingredients in most fertilizers. The other, more common macronutrients are called secondary nutrients, as they are not of as much importance. Micronutrients, the other classification, consist of all the other elements and compounds required for sufficient growth, such as iron, boron, manganese, copper, zinc, molybdenum and chlorine. In some cases, these nutrients are found to be missing in soils, but it is extremely uncommon.As plants need to retrieve all of their nutrients from the soil, many methods have been developed in order to find ways to improve or change the soil to suit the plant's needs. Soil, in science as well as in common gardening, must undergo detailed inspection, to detect such things as the pH of the soil. A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill plants. Mineral content, as mentioned above, is also a concern, and must be clearly monitored. After inspection, it is common for minor organic materials outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold. It is after these steps that fertilization must occur, leading to a debate which has plagued gardeners and scientists alike: organic or chemical?Fertilizers, in both natural and synthetic breeds, are carriers of the primary and secondary nutrients that are found less often in even the most fertile soils. Fertilizers are mixtures that are mixed or applied to soil, thus greatly increasing its potency and maximizing plant growth. As mentioned before, however, there are both natural and inorganic fertilizers, all with varying effects. The compositional differences of these types are great, indeed. Natural fertilizers, as one would...

Myc-dependent Synthetic Lethal Targeting of eIF4F and mTORC1

2567 words - 11 pages Myc is a transcription factor that is often duplicated or over-expressed in cancer. Myc-driven cancers are often more resistant to treatment and have a worse survival rate than cancers in which Myc expression is normal1-3. Targeting Myc directly has been unsuccessful, therefore it is of interest to find other targets in Myc-driven cancers. The two papers presented here examine Myc-dependent synthetic lethal targets. In Myc-driven cancers, these

Differences between Natural State in Hobbes and Locke

In Locke's state of nature we have all men created inherently equal being subordinate only to God. Although Hobbes also states that all men are equal it is only because no man has the strength to maintain absolute authority over another. Hobbes recognizes two different states

Natural kinds are a group of entities existing in nature and having many commonalities along with forming many hierarchical organized categories (Sloutsky & Fisher, 2004).

According to Gelman and Markman (1987), new features learned about one category member will often be projected onto other category members as
