Document Summary

The nutrients/food components are what we need to meet our dietary requirements: macronutrients (large, need gram / hundred of gram quantities of these per day) protein, fat, carbs: micronutrients (small, need milogram / microgram quantities of these per day --- 1000th of a milogram) Training effect isn t felt unless you train 2+ times a week: training effect is directly related to the intensity of the activity. You can enhance your performance by what you eat before and during activity (even afterwards) Electrolytes: mineral particles that are within the body and also within water. because in order to build muscle you need to gain some fat. Re member: low calorie diets are the worst way to change your body composition! Ergogenic effects of selected substances slide 8. There will always be a notation/reference (ziegenfuss et al (2002)), where you can look up information on the study online.

Can you please write out any possible pitfalls you anticipate with the experiment below?

GRAVIMETRIC DETERMINATION OF PH OSRPHORUS IN PLANT FERTILIZER 2. 2.1 INTRODUCTION nglysis is a method of quantifying an analyte through the determination of, of the analyte. In the following experiment, you will quantify the present in plant fertilizers by isolating the phosphorus content amount of phosphorus and reacting it to form a solid precipitate. This precipitate ill be measured using the and rea weich-by-difference technique and the weight of the precipitate can be used to reactions required to form the precipitate). In order for plants to grow healthy, they require these basic chemical elements (listed ine the initial amount of phosphorus in the fertilizer (by looking at the chemical below in order of importance) Carbon (C), hydrogen (H), and oxygen (O): readily obtained from water and carbon dioxide Nitrogen (N), phosphorus (P), and potassium (K): called primary macronutrients Sulfur (S), calcium (Ca), magnesium (Mg): called secondary macronutrients Boron (B), chlorine (CI), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu) molybdenum (Mo): referred to as micronutrients - - Soil generally provides the macro and micronutrients, however, the primary macronutrients (N, P, and K) are so crucial for plant growth and survival, that plants can deplete soil of these nutrients during early stages of growth. Plant fertilizers are generally added to soils to provide an additional supply of the primary macronutrients and in some cases to add micronutrients). Plant fertilizer Plant fertilizers represent the amount of primany macronutrients with a 3 number label, often referred to as the N-P-K value. The N-P-K value is the mass percent of Nitrogen, P:0sj and the mass percent of potassium (in the form , the mass percent of phosphorus (in the form In Figure 2-1:Afertlier with the NPK the Green light is shown and we see the igure 2-1, a bottle of 12-55-6 value of 12-55-6 which indicates that the fertilizer is composed of 12% N, SS% P20s, and 656 Kro. fertilizer Adapted from Solomon, The reason that phosphorus okdised n S. lee A, Bates D.
