Lab Experiment : Lab Analysis Of Soquid Feertilizer

The purpose of this lab was to figure out which would be a better buffer, lime juice or potato juice? We found through our observations and our data that our hypothesis that potato juice would be a better buffer was incorrect. For example in the beginning of our lime juice and potato juice trial when we mixed hydrochloric acid at zero drops the pH of the lime juice was 3.3 and after 30 drops of hydrochloric acid the pH of the lime juice was 2.6. In comparison the pH of potato juice at the beginning of the hydrochloric acid trial was 7.0, and after 30 drops the pH changed to 4.1. So the difference in pH in the lime juice was less than the pH of potato after 30 drops of the acid. This data proves that our hypothesis that potato juice would be

After looking at the results of this lab, we noticed that the growth in the first Nutrient agar plate had a multiple bacterial growth, but for the sabouraud dextrose had variety of fungus which means that the fungi grow isolated from other microorganism in the soil. For the second Nutrient agar plate we saw a clearing on the 4 areas that we added the soil on which means that the fungus had produced the antibiotic (penicillin) to inhibit and kill the other microorganisms.

Over Fertilization occurs when more nutrients are added to the soil than the growing plants can utilize unused nutrients are then carried away by irrigation or rain water. Several factors can result in over fertilization. For example, it is difficult to determine precise nutrient content in some organic fertilizers, like manure. As a result, actual nutrient levels may exceed estimated content, and over fertilization occurs. Also, gardeners may incorrectly diagnose poor plant growth as a nutrient deficiency and apply fertilizer as a corrective amendment. In fact, the true problem could be unhealthy roots, poor soil conditions or other improper care. To prevent overfertilization, have soil tested regularly to determine accurate nutrient levels and only apply fertilizer as

So firstly we calculate the amount of HCl used, which is 0.000846mol. Then, because NaOH and HCl react with a ratio of 1:1, we can determine the NaOH reacted with HCl is also 0.000846mol. After that, we can subtract this amount from all 20 ml NaOH added to the sample, so the amount of NaOH reacted with sample is 0.00107mol. This part of NaOh reacts with ammonia at a ratio of 1:1. So the amount of ammonia is 0.00107mol, containing 0.18g nitrogen. Finally, we say show that the proportion of nitrogen in the fertiliser is 13.8%

The method I used in the experiment was followed by the lab manual of “Fundamentals of Life Science by Brenda Leady” (Leady 2017). We conducted an experiment of 8 different tests, 4 of the different classifications of pH, and 4 different

In order to test the acidic pH (5.0) a cocktail containg 20.0ml of disttiled water and 1.0ml of chloroplast suspension were used. Instead of interesting the neutral Ph, 6.0ml 0.2M phosphate buffer (pH 5.0). Each test tube, W, X, Y, Dark, and Room were given the exact parameters as activity I. A set distance was placed of 34cm, 70cm, and 99cm respectively for each letter variable and both positive and trial run. Furthermore, a standardized curve was created with the similar dilution factors of activity II, but 0.2M phosphate buffer (pH= 6.0) was replaced with 0.2M phosphate buffer

This experiment was focused on the effect that salt water has on bean plants, as opposed to tapwater. Specifically, does watering a plant with saltwater, instead of tap water make plants grow healthier or faster? It was hypothesised that if a plant is watered with only salt water, then the plant will not grow as well as one watered with tap water. During this experiment, The quantitative data that was collected included the plant height and the amount of salt that accumulated on the surface of the soil. The qualitative data was the color of the plants, soil, salt clumps, and the appearance of the plants overall.

Purpose of Project The purpose of this project is to see if there is a difference in how plants grow based on what they are watered with. By watering five different plants with five different liquids and measuring them daily we will prove or disprove the hypothesis.

Testing your soil is an important first step to a successful garden. The initial soil test will tell you what contaminants your soil contains, if nutrient

Soil is an amazing combination of minerals, water, air, organic matter and living organisms. It can provide the physical support for plants as well as provide access to water, air, and nutrients that are necessary for plant survival, growth, and productivity. Much of our success in home vegetable production depends on the proper selection of sites and soil and management of soil nutrients. Those topics are covered in W 346-A- The Tennessee vegetable garden: Site selection and soil testing and W-346-C- The Tennessee vegetable garden: Managing plant nutrition. This factsheet is designed to build upon that information with more in-depth discussions on managing the quality of garden soil.

To begin, as spring gets into full swing we tend to see an increased use of fertilizer because landscapers as well as individuals are excited to turn the dead brown grass and plants caused by winter into lushes blooming beautiful works of art. To maintain a healthy environment in the process humans, need to insure they are following the ordinances in place to ensure the environments remains in a healthy state. In this paper, we will discuss State and Local ordinances regulating the application of fertilizer, Training programs offered to ensure fertilizers are being used properly and safely, what times of the year you can apply fertilizer, the impact of total nitrogen reduction, and fertilizer free zones. Fertilizer ordinances are put into

Approximately 2000g of a soil sample that passed a No. 4 sieve was measured. Calculations were done for how much water should be added to reach the desired moisture content. The calculated moisture was added with a spray bottle and mixed thoroughly in the sample. The sample was then placed in a cover container. These steps were done prior to the experiment.

Some say that chemical fertilizers are necessary for the growth of crops and that the chemical fertilizers are necessary in order to keep up with the everyday increasing demands of the human consumption rate, but are chemical fertilizers truly necessary? It is true that chemical fertilizers do help produce an efficient yield, but what natural process is undergoing replacement in order to speed things up? Some say that chemical fertilizers are irreplaceable since they produce the necessary nutrients for a plant to grow (N-P-K), but are chemical fertilizers truly irreplaceable in the eyes of society? Could not the bones, soil rotations, and the ancient methods our past generations discovered provide the nutrients a plant need? Some say that chemical fertilizers are overall beneficial to the human race thanks to everything they provide us: food, money, jobs, and lower malnutrition rates throughout the States, but are they really overall beneficial? This paper will talk about the negative impacts that chemical fertilizers have on soils in the long and short term and how the health of the people consuming chemically fertilized foods is undergoing alteration, to do so it is essential to look at the origin and history of chemical fertilizers.

It is easy to take for granted how the food we eat was grown, how the putting green at a local golf course is so nice, or how decorative houseplants become so large and beautiful. The secret behind all these everyday pleasures is fertilizers. Fertilizers supply the nutrients necessary to a plant that are not as abundant as oxygen, hydrogen, and carbon. Fertilizers are an important part of farming because it allows for better growth and a larger yield. Not only are fertilizers important for farming, but they are also used on golf courses, private lawns, and in gardening and landscaping. Chemistry is the very foundation of fertilization due to the chemical elements and how they operate, the purpose behind fertilizer, the time frame, the

Increasing the nitrogen uptake plants by using artificial fertilizers upsets their carbon/nitrogen balance causing metabolic problems to which the plant reacts by taking up extra water.
