The Scientific Method “The "game of science" begins with the scientist ’s asking questions about a particular phenomenon which he has observed. He wishes to find out how it behaves and why‚ in the sense of determining relationships between it and other phenomena.” (Kariel‚ Herbert G.‚ 1967‚ California Geographer: Using the Scientific Method to Solve Geographic Problems‚ Vol. 8‚ p. 21) The scientific method is the methods used by scientists to answer questions or solve problems.

was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount of Miracle Grow Fertilizer Solution were doubled‚ the radish

What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health. The USDA must approve all products claiming to be organic and there are many strict guidelines farmers must follow. Farmers must abstain from the use of prohibited materials (pesticides‚ synthetic fertilizers‚ and

pollutants naturally (Bradsher‚ 2008). Even before construction began on the 3 Gorges Dam the Yangtze River was already suffering from extreme pollution but the addition of the dam has increased pollution levels. One reason is the use of commercial fertilizers‚ another is sewage from passenger boats that tour the river and reservoir (Yangtze Pollution Irreversible) and finally and possibly most serious is the increased greenhouse gas emissions from decaying vegetation. Farming has long been a fruitful

methods such as pesticide and non-organic fertilizer use‚ or antibiotic and hormone use. Thesis statement: Many people just don’t trust these chemicals and don’t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides‚ fertilizers and other chemicals‚ the only way to avoid them is to buy organic foods. Introduction Organic foods are grown without using most conventional pesticides and fertilizers. A product that is identified as being

In the 1940s‚ the Green Revolution was introduced to the world. The Green Revolution consisted of new methods of harvesting crops‚ fertilizers and pesticides were introduced‚ and companies were able to mass produce crops. This revolution started when the Rockefeller Foundation launched a research project to hope to improve the agriculture in Mexico#. New technological advances helped the revolution spread on account of the fact that a new‚ more effective and productive way to harvest crops was invented

important mineral nutrients. The origin of these elements is in the rock and soil minerals of the lithosphere‚ examples include iron‚ calcium‚ and potassium. The impact of humans in this cycle is the use of phosphorus containing fertilizers. Phosphorus is used to make fertilizers‚ animal feeds‚ detergents and other products. Unfortunately the amount of phosphorus has tripled the amount of phosphorus reaching the oceans. The problem is that there is no way to return the waterborne phosphorus to the soil

HISTORY OF INDIAN AGRICULTURE Early history Barley and wheat cultivation—along with the domestication of cattle‚ primarily sheep and goat—was visible in Mehrgarh by 9000 BCE. Vedic period – Post Maha Janapadas period (1500 BCE – 200 CE) The Mauryan Empire (322–185 BCE) categorised soils and made meteorological observations for agricultural use. Early Common Era – High Middle Ages (200–1200 CE) Water storage systems were designed during this period. Kallanai‚ a dam built
