Crop Rotation and Soil Sustainability Essay -- Agriculture Farming Pap

Crop Rotation and Soil SustainabilityAgriculture is responsible for providing food for an ever-growing population, and as it becomes deport that yields cannot continue to rise without limit, sustainability of agricultural practices becomes an increasingly important question. The soil is a precious resource in which all of agriculture has its base, and careful management of this colonial system is essential. Crop rotation is one of the most important management practices in a sustainable agriculture system, both as a bureau of conserving soil and of maintaining its fertility. A well-thought-out crop rotation is worth seventy-five percent of everything else that might be done, including fertilization, tillage, and pest control according to The New Organic agriculturist (Coleman, 1989, p. 50). Crop rotation is by no means confined exclusively to thoroughgoing farming, although much of what is considered in planning a rotation sequence encompasses the concerns of the organic farmer. The difference is primarily one of sustainability. The organic farmer is essentially turning part of his potential income into renewal of the soil (by adding organic matter) in order to insure sustainability of future crop production. The conventional system maximizes present income and is not as concerned about viewing soil as a long-term enthronization (Poincelot, 1986, p.23). A varied sequence of crops provides benefits that a monoculture cannot. A monoculture is an unnatural system the relationship between soil, plants, and climate is designed to be balanced by diversity.

A site had to reach certain criteria in order for it to be made into a facility in helping to produce the atomic bomb. Part of Groves criteria was that a site had to be twenty mi les from any town made up of a thousand people or more (Goldberg, Atomic 50). The reason a site had to be away from a large town was in case of an accident at the facility.

Altogether, specific criteria had to be met to protect the security of the atomic bomb project and to protect the people that lived around the area. Even though decision a perfect location site seemed difficult, Groves knew that it was possible to find a site that matched the specifications for an atomic bomb production site.

Rebuttal of Bell Hooks’ Article, Straightening My Hair :: Rebuttal

Rebuttal of Bell Hooks Article, Straightening My HairThe article Straightening My Hair by Bell Hooks makes her argument of finding the reason of why African American women straighten their vibrissa. She first states that Black Americans straighten their hair because it is the stage of turn it closes the door of innocence and opens the door to adulthood. Slowly, she starts changing her views. She comes up with the statement that African Americans do not straighten their hair for reasonable reasons, but to imitate the characteristics of etiolated women. She informs that calamitous people repeat this process because they have low self-acceptance of their roots and background, and that they have lost beauty in themselves. My argument against this statement is that it is erroneous to acquire that the straightening of African American hair is misinterpreted as their acceptance into the white community straightening of hair is the symbolism of impending womanhood, closing the door of innocence, and sharing a cadence to meditate by relaxing your soul. Hair pressing was a ritual of black womens culture (Hooks 534). She stated this earlier in the article and changed her views sorrowful into the depths of the article. With her claiming this quote, it has already set the tone that black women express their maturity and symbolism of growing into adulthood by straightening their hair.

The audience view that her facts are not accurate and people begins to doubt in her claim.She set the theme of the article of expressing that straightening of black people hair is the denial of self acceptance in having the confidence of their individual features. She states Heterosexual black women talked about the extent to which black men answer more favorably to women with straight or straighten hair (Hooks 538). She explains how they try to please other people in trying to make the mselves more fine-looking to others they want to attract. This is a personal opinion. She makes a broad generalization that all black men are attracted to women that have straight hair. This statistic is not efficient because thither are different men that are attracted to different styles. The majority of people do not change themselves because they want to appeal to others, but to make themselves detect better about their personal beauty.She states, Individual preferences (whether rooted in self hate or not) cannot negate the reality that our collective obsession with straightening black hair reflects the psychology of oppression and the impact of racist colonization (Hooks 540).
