Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

of the overall process on the stoichiometery for growth and product formation (3). An aerobic fermentation process may be represented as: Carbon and energy source + Nitrogen source + O2 + other requirements Biomass + products + CO2 + H2O + heat This primarily involves consideration of the input of the carbon and nitrogen sources‚ minerals and oxygen and their conversion to cell biomass‚ metabolic products. Based on this information‚ it should be possible to calculate the minimum quantities

Michael Pollan‚ The Omnivore’s Dilemma: The Secrets Behind What You Eat (Young Reader’s Edition) - Grade 7 Originally published in New York: Dial Books‚ 2009. Learning Objective: The goal of this two day exemplar is to give students the opportunity to use the reading and writing habits they’ve been practicing on a regular basis to unpack Pollan’s investigative journalism of industrial farms. By reading and rereading the passage closely combined with classroom discussion about it‚ students will

gases that come from car exhaust are carbon dioxide and nitrogen oxides. If too much nitrogen oxides get put into the atmosphere‚ the balance of the natural amount within the atmosphere can go out of proportion. Nitrogen oxides‚ on the other hand‚ come from burning coal‚ natural gas‚ gasoline and oil. The biggest cause of this gas being put into the air is from car exhausts. In addition‚ gas that is being used in lawnmowers also emits nitrogen oxides‚ however in smaller amounts. Along with those

A naturally occurring element that is pertinent to the growth of organisms along with the reproduction of them‚ nitrogen plays an important role in the ecosystem. Ask yourself this‚ “If organisms were not able to reproduce‚ would there be any kind of species left on earth?” It’s obvious the answer is no because of the element nitrogen and here’s why. This element is found in amino acids which means that it is a basis for proteins. What proteins do is simple‚ they regulate

British physicist named Lord Rayleigh asked chemists to explain the difference between the atomic weight of Nitrogen found in chemical compounds and the heavier‚ pure Nitrogen found in the atmosphere. Ramsay and Rayleigh were communicating daily with their results to solve their curiosity of the unknown gas. Rayleigh determined that a liter of pure Nitrogen weighs 1.2505 grams‚ but a liter of Nitrogen gas generated from air‚ by removing the Oxygen‚ Carbon Dioxide‚ and the water vapor‚ weighed 1.2572 grams

For example‚ a 20-20-10 fertilizer would contain 20 percent nitrogen‚ 20 percent phosphorus and 10 percent potassium. Secondary nutrients and trace elements are typically listed.

Earth: A Living Planet To care for our planet we must understand how it opperates. Ecology is the study of interactions of organisms with one another and with their physical surroundings. Scientists who study ecology are called ecologists. Earts is a biosphere‚ or a living globe. The biosphere is that part of the Earth in which life exists. Biospheres include all the areas of land‚ air‚ and water on the planet. The biosphere goes about eight kilometers above the Earth’s surface to as far as eight

Cars: past‚ present & future Throughout the history of the automobile‚ there has been one factor that has determined its evolution. That factor‚ quite simply‚ is innovation. Every once in a while‚ there comes along a car that is so revolutionary‚ and has features so unique that the entire industry soon follows. This paper will help u understand how this process works‚ but to help you understand better ill take u back to when cars came from thought to reality ‚ then I’ll show u how far we have
