How To Approach A Poem--Analysis Of A. E. Houseman's …

Below is the poem, with some notes towards an analysis of its meaning and language.
If the only indicator of the need for fertilization is slow shoot growth, then a high nitrogen fertilizer should be applied to the tree following the recommendations in the "What to apply" section of this guide. If, however, the leaves of the tree are yellowing, or there is some other indication of a nutrient deficiency, then it is appropriate to take a soil sample from around the root zone of the tree and have a soil analysis performed.

Foliage color is another indicator of the need for fertilization. Yellow or "off-color" leaves may indicate the need for fertilization as these symptoms generally occur on trees which are not taking up enough of one or more required nutrient. Always remember, however, that apparently "off-color" leaves are normal for certain plants such as 'Sunburst' Honeylocust and some maple and ash trees in the fall.

Some soils in northeastern and central Minnesota have low pH levels (5.5 and below) which may negatively affect trees by reducing the availability of some nutrients and increasing the availability of aluminum, a potentially toxic element. In low pH soils, lime can be applied to raise the pH to a level that is more beneficial to the plant. Liming is best done before a tree is planted. Do not add lime unless a need is indicated by a soil test.


If a tree shows yellowing, extremely slow growth, or some other sign which might indicate a nutrient deficiency, then fertilizer can be applied at any time during the growing season. If fertilizer must be applied under the hot, dry conditions of the summer, it is important to provide water for the tree soon after fertilizer is applied so that salts from the fertilizer don't build up and damage the tree's root system. Two to three inches of water (as measured by a rain gauge) applied every two or three weeks around the area where fertilizer was applied will be sufficient to wet the top 1-1 1/2 feet of most soils. Sandier soils will require lighter, more frequent watering while clay-based soils will require heavier watering less frequently.

The most fundamental difference between fault tree diagrams and RBDs is that you work in the "success space" in an RBD while you work in the "failure space" in a fault tree. In other words, the RBD looks at success combinations while the fault tree looks at failure combinations. In addition, fault trees have traditionally been used to analyze fixed probabilities (i.e., each event that composes the tree has a fixed probability of occurring) while RBDs may include time-varying distributions for the blocks' success or failure, as well as for other properties such as repair/restoration distributions.

Decision tree learning - Wikipedia

Unless a tree is deficient in some other element, increased nitrogen provides the most pronounced effects on the growth of all plant nutrients. Just because an increase in nitrogen produces a more visible increase in growth, however, does not mean that other elements are not required. A soil test provides the best indicator of elements that may need to be added to the soil to prevent nutrient problems. High rates of P fertilizer should not be used unless a need is indicated by a soil test. If soil test P is high then it is best to use fertilizers such as 24-0-15, 30-0-10, 32-3-10, 18-5-9, 27-3-3, or 16-4-8 with a high rate of N and a low or zero rate of P. High rates of P can negatively affect the environment by causing excessive algae to grow in nearby lakes and streams which will, in time, kill fish and other aquatic life. Never use a fertilizer which includes any kind of herbicide around a tree. These fertilizers may be beneficial to turf, but can damage trees.

Decision tree learning is a method commonly used in data mining

Fault tree diagrams (or negative analytical trees) are logic block diagrams that display the state of a system (top event) in terms of the states of its components (basic events). Like reliability block diagrams (RBDs), fault tree diagrams are a graphical design technique, and as such provide an alternative methodology to RBDs.
