Animal manure Some animal manures from conventional farming practices could be contaminated with hormones, antibiotics, pesticides, disease organisms, heavy metals, and other undesirable substances. Because of this animal manures must come from organic sources. Manure testing is available through commercial labs and is recommended in situations where there is any doubt about the purity of manures. Manure testing is required by the European Union. Dairy and beef cow, horse, sheep, swine, and poultry manure can be spread directly on land and incorporated. The amount of nitrogen in manure sources from different animals can vary by a factor of 3 or 4. The amount of nitrogen in the fresh manure that ends up available to the plant is also very …show more content…

Crops grown to add nutrients to the soil are called green manures and are usually sown in late summer or autumn. Some plant species are selected as green manures or cover crops, because of efficient, deep root systems that bring nutrients up to the soil surface, others because they are hardy or more tolerant of nutrient, moisture or environmental stresses. The most important green manures are plants that together with bacteria are able to capture nitrogen from the atmosphere and make it available to plants. Examples of green manures are Trifolium repens (white clover) and Trifolium incarnatum (Crimson clover). Green manures can also be used to cover bare patches of soil in the spaces between crops, or during intervals between one crop and the next. Fast-growing mustard sown before mid-September can be incorporated in October, for example, or the frosted remains left as mulch. Other benefits of green manures include protection of the soil surface from compaction by rain and shelter for beneficial insects such as ground beetles. (www.rhs.org.uk, 2015) The effect of green manures or cover crops on rodent populations or rodent damage to trees must be taken into consideration. (Biernbaum, 1994)

Abstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary

In her personal narrative, Bonnie Jo Campbell describes to her readers the time she sold manure the summer after school let out. At first, Campbell was embarrassed to deliver manure; however, over time, she began to realize selling manure was beneficial for both her and the customer, and quite fulfilling as well. Campbell (1996) states, “Within about a week, however, I began to see the absurdity of our situation as liberating” (p. 30). She begun to understand that selling manure was an honest vocation as opposed to her first thoughts. Not only is manure delivering effectual, but also are the other countless overlooked jobs often seen as low class citizen jobs.

In the US, 40% of food produced, or approximately 365 million pounds of food, is wasted each day. Food waste, however, is a problem that extends beyond America, affecting billions of people as a global issue. The overwhelming amounts of food that are being discarded contribute to global warming and climate change, and prevent the massive number of hungry people from being able to eat nourishing meals. Humanity as a whole must be more mindful of the Earth and its health, as we are the source which most directly affect it. Due to the profound environmental impacts of food waste, a reduction in the amount disposed is necessary to create a more sustainable environment, and humans have a responsibility to protect the planet, even if it requires drastic changes to the current food system.

Animal Experimentation: Is it Beneficial? Animal testing, otherwise known as vivisection has been around prior to the 19th century, in fact, in 1973 there was already a total of over 1,500,000 animals being experimented on.

Depending on the processing methods employed to produce them, commercial pet foods fall into one or the other of the following two categories: heat-treated and raw. So-called 'heat-treated ' pet foods are processed using all-too-often excessive levels of heat. These foods are baked, cooked (canned), extruded, or heat-dried (often the case with kibble- or pellet-type pet foods). Diets based on such heat-treated pet foods are probably the least desirable in terms of maintaining the health and general well being of most animals. Heat processing of food destroys all enzymes, many vitamins and antioxidants, and changes the molecular structure of proteins and even fibers.

Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
