Soilection I am doing my speech on something I am somewhat familiar with. My topic is Variable Rate Fertilizing (VRF). I somewhat know about this topic because my dad a company that does the VRF and the practices that come with it. In my paper I will be talking about what machines are used and some details about them. I will also be talking about the different fertilizers used and explain why they are used and what plants use what nutrients. I will talk about the soil samples we take from the fields in order to accurately know what the field needs and where it needs it. These are the main topics I will be talking about in my paper I think I will start with telling you what VRF is. VRF is where we use a large machine to spread fertilizers on fields. Fields need fertilizer because crops take nutrients out of the ground. The plants don’t put it back the nutrients, because we harvest the fruits and vegetables that the plants use the nutrients to create. Without the proper nutrients crops will produce fewer yields and or no yield. Having proper nutrients on your field is very important to the success of the crop. There are many nutrients that soil may have access or lack of. Some of those are nitrogen and sulfur. Corn highly uses nitrogen. After a crop of corn a farmer would need to apply nitrogen to his field in order to have successful future crops. Next I am going to talk about techniques of soilection. Most farmers are used to dumping 900 pounds of nitrogen give or…
Nutrition has a lot of components under it, like carbohydrates, fiber, protein, fats and more.
But let’s start with carbohydrates; well there are simple and complex carbohydrates. A carbohydrate is an organic compound with the empirical formula Cm(H2O)n (where m could be different from n); that is, consists only of carbon, hydrogen, and oxygen, with a hydrogen: oxygen atom ratio of 2:1 (as in water). Simple carbohydrates are also called simple sugars and…
The first nutrient to start breaking down in the cheeseburger will be the carbohydrate. Carbohydrates break down immediately when coming into contact with salivary amylase which is found in the mouth. Salivary amylase hydrolyzes the starch into an oligosaccharide. As the carbohydrate travels down the esophagus into the stomach the amylase becomes denatured by the low pH in the stomach. Once through the stomach it, passes into the small intestine where it comes into…
Acquiring and Transporting Nutrients
There are many important factors that are vital to the functioning of the human body. Three important components are the digestive system, cardiovascular system, and the respiratory system. Without these three systems we would not be able to breathe, transport nutrients, or dispose of waste.
The cardiovascular system is a very unique system of the body that deals with the heart, blood vessels, and blood. The functions of the cardiovascular system are…
fuel (for chemical energy to turn into ATP), raw materials (carbon and nitrogen-containing macromolecules), and essential nutrients.
Define essential nutrients. Describe the four classes of essential nutrients.
Essential nutrients are chemicals an animal can not make itself and therefore must be included in the animal’s diet. There are four main classes of essential nutrients:
Essential amino acids - 8 of the 20 different amino acids can’t be be chemically synthesized so they must be included…
color) in darker skin protects
against sun damage, but it can also block the sun needed to produce vitamin D.
Certain health conditions. Some health conditions, like cystic fibrosis or inflammatory
bowel disease, affect how well the body absorbs nutrients, including vitamin D. And
because vitamin D is a fat-soluble vitamin that gets stored in the body's fat cells,obesity
increases a person's risk for vitamin D deficiency.
Lower consumption of D-rich foods. Experts recommend eating vitamin D-rich…
B. A healthful diet can prevent some diseases and reduce your risk for others.
1. Nutrient deficiencies can cause serious illnesses.
2. A healthful diet can reduce risk for chronic diseases.
III. What Are Nutrients?
A. Nutrients are chemicals found in foods that are critical to human growth and function.
B. Carbohydrates, fats, and proteins are nutrients that provide energy.
1. Energy is expressed in units of kilocalories (kcal).
a. Carbohydrates provide 4 kcal…
Digestive tract problems are often the main issue caused by elevated folic acid.
Bloating, gas, and diarrhea can all lead to discomfort in those who ingest too much of
this vitamin, whether through too many supplements or too much food that contains this
nutrient. Nausea and loss of appetite also often occur with high levels of folic acid,
which means that some of the most common symptoms can interfere with the daily
routine of most people suffering from this condition.
Less serious side effects include digestive problems…
Denitrification: Denitrification occurs in the conversion of Nitrate ions into Nitrogen gas which is released back into the atmosphere for the cycle repeat.
Nitrogen is essential in the growth and survival of all organisms. Nitrogen is one of the primary nutrients critical for the survival of all living organisms (Earth System Science, 2004). Nitrogen is one of the key components of amino acids which create all proteins. It is also an important ingredient to the process in which DNA produces and replicates…

Plant Nutrients Inc. (PNI) is operating in an industry requiring constant innovation in order to combat declining prices. In the case of PNI, it is critical that Brian Dunwoodie acknowledge where the company’s competitive advantage lies, and continue to leverage PNI’s ability to sell to small farms well. PNI should incorporate a seed business into its current business model through a strategic partnership with Larson Seeds, giving PNI the ability to offer a complete agronomic…
