Convert the grams to to pound to tons. This will provide the available dry matter of an acre. Use the rising plate meter and other commercial devices to determine yield to show other, more accurate methods of determining yield. Lab report ideas: Laboratory reports provide the opportunity for students to apply what they have seen and done in the exercises to forage management decisions and place knowledge and skills into long-term memory. Present a few more opportunities to do the calculations on the lab report to shift the learning into long-term memory. The lab report may also include: List your estimated yield and your calculated yield.

Write down your estimation. This may help determine when to rotate livestock but is not an accurate method for determining yield. Determining the yield of random square feet provides a more accurate yield. Select a square foot and clip the forage to 2 inches above the soil. Collect the cut forage in the bag. Repeat this for 3-4 squares. Dry the bags of forage clippings in an oven overnight at 300 degrees. Weigh an empty bag in grams. Weigh the bags of clippings. Subtract the weight stationary of the bag to determine the dry matter weight of the forage for each sample. Multiply the weight by the number of square feet in an acre, 43,560 square feet per acre.
Materials needed: Outdoor pasture area, rulers or yardsticks, scissors, oven, bags (lunchbags pencils, paper for notes, calculators, rising plate stick. Procedures: Introduction: Ask how much forage is in the pasture? How can we biography determine what is available for livestock? Brainstorm on how you might go about answering that question. Input: Not all the forage growing here is available to livestock. The lips, teeth, tongue, and jaws of the animals will determine how closely the animal can eat to the ground. Most cannot get closer than 1-2 inches and we should not want that. There are three main ways to determine how much forage is available for livestock. Some people take an estimation by how high the grass is to the boot.
When teaching about concrete items such as plants, laboratory exercises can be very fruitful. Most students proposal have a preferred modality, usually visual, and resume the lecture-style presentations of most classes do not provide the best learning for visual and kinestetic learners. Laboratory exercises can prove very beneficial to both. This section will offer ideas and exercises for forage-related lab and field trip activities. The activities are presented under the subject (weeds, hay, species identification, fencing). Each activity will include: objective, materials, procedure, lab report ideas, and educational strategies. Subject: yield, objective: to help students determine yields; comparing estimation with square foot calculations.
Years of research has shown limited calibration among various soil extractants and nutrients. Currently, the soil extractant identified and recommended on such soils is ab-dtpa, which has shown calibration with only phosphorus, with a critical limit of 10 mg/kg. However, due to long term intensive management of agriculturally managed calcareous soils in fl, the soil P levels are around 30 mg/kg, generally rendering the approved ab-dtpa method to be of a limited value. Other nutrients such as k, etc did not yield in any reasonable calibration. Efforts are still on-going to identify a suitable soil extractant for these soils and latest information can be obtained by contacting.

The calcareous soils of miami-dade and other counties typically have day soils up to 80 caco3. A comparable calcareous soil in other regions of the us will have around 10-20 caco3. It is therefore unique.
Here is your opportunity to relate the laboratory work to the physiological principles dealt with in the lecture and/or the textbook. It is critical that you cite authors or footnote any information that you have derived from physiology texts. If you fail to give credit where credit is due, you are violating ethics and standards for written communication. Also, in your footnotes or references, please state page numbers of texts and articles to which you have referred for information included in your discussion. Speculations on possible consequences of your results, on other experiments which might clarify a point, or on other techniques which may have given more definitive results are highly encouraged.
These should be presented in addition to the discussion of conventional concepts. Remember that the teacher is looking for clear thinking and understanding of the experiment performed. In summary, your discussion should show how you fulfilled the purpose of the experiment as stated in the introduction. This will hopefully provide a central theme and some semblance of unity to the report. Assistance: feel free to discuss with me the various aspects of this lab report. I will be glad to examine a preliminary draft of your write-up, providing helpful comments, before you write your final draft. This requires that you get an early start on your write-up and not wait until the day before it is due. Even if you understand how to write a lab report, having me evaluate your rough draft is virtually guaranteed to improve your final draft (and your score).

Some forms of data reduction are easier to interpret than others. You may want to display your data in graphic form rather than report raw values, especially if you are trying to emphasize a trend or pattern. Necessary calculations and resume formulas should be shown. If you have repeated measures for some parts of an experiment or a large number of subjects, use "means "standard deviations" or "standard errors and ranges to reduce the data into an interpretable form. This will make comparisons and contrasts with known values much easier to explain. Discussion: This section is the real "meat" of the paper. In it, a detailed interpretation of data is integrated with known physiological concepts, and comparisons are made between your results and expected results. This portion of the paper gives you the opportunity to display your intelligence, creativity, powers of synthesis, and your ability to work with concepts you have learned.
It is also not sufficient to include tables of data, graphs, figures, etc., without some written explanation. Therefore, this section should ideally consist of a brief written description of observations and homework results with references made to figures, graphs and data tables. Always number your figures and tables in the order that they are described in your text. Do not hesitate to cut up penwriter records of experimental results to mount as illustrations. Such records should include the time scale and sensitivity of the physiological response pictured. Be sure each table, graph, or figure is clearly labeled (for example, figure 1 - oscilloscope Tracings of Frog Compound Action Potential). Remember, the results section is the portion of the paper in which data are reported and summarized in a clear, concise manner.
experiments that have led. Therefore, your introduction should reflect an appreciation of the particular systems to be studied, keeping in mind that some ingenious individual at some time in the past designed and executed the experiment you are doing without referring to a lab manual. Methods: Describe these very briefly. There is no need to duplicate the instructions in the lab manual, but cite the lab manual and state any deviations from the printed procedure. These would include modifications suggested by your instructor or modifications you initiated. Also note any methodological omissions and justify them. This part of the write-up should also include a description of animal or human subjects. Results: In this section, the reader is given a description of the data and observations that resulted from the experimental procedures. This section of the paper is not the place to interpret results.
Introduction: This is a brief explanation of write why the observations you made are of physiological significance. That is, what physiological principles are involved in the exercise? What do you hope to demonstrate? Most scientists are not prone to pursuing research without a reason. One stimulus for doing an experiment is that the scientist wishes to answer a question or resolve a controversy. Whatever the reason, the scientist must communicate the purpose of his/her research prior to explaining the details of the experiment. In an undergraduate physiology class, you may be hard-pressed to find a reason for doing the particular lab exercise you have chosen.
