Chemical Fertilizers vs. Organic Fertilizers INTRODUCTION Agriculture is the most primitive occupation of the people which mainly needs land to grow different crops for food and as raw materials for different industries. Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food. Land contains

Fertilizer (or fertiliser) is any organic or inorganic material of natural or synthetic origin (other than liming materials) that is applied to soils or to plant tissues (usually leaves) to supply one or more plant nutrients essential to the growth of plants. Conservative estimates report 30 to 50% of crop yields are attributed to natural or synthetic commercial fertilizer.[1] Global market value is likely to rise to more than US$185 billion until 2019.[2] The European fertilizer market will grow

GRAVIMETRIC ANALYSIS Methods in GA Precipitation Method - involves isolation of an ion in solution by a precipitation reaction‚ filtering‚ washing the precipitate free of contaminants‚ conversion of the precipitate to a product of known composition‚ and finally weighing the precipitate and determining its mass by difference. From the mass and known composition of the precipitate‚ the amount of the original ion can be determined. Volatilization Method -the analyte or its decomposition products

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

the supply or availability of primary nutrients to the host plant.[1] Biofertilizers add nutrients through the natural processes of Nitrogen fixation ‚ solubilizing phosphorus‚ and stimulating plant growth through the synthesis of growth promoting substances. Biofertilizers can be expected to reduce the use of chemical fertilizers and pesticides. The microorganisms in biofertilizers restore the soil’s natural nutrient cycle and build soil organic matter. Through the use of biofertilizers‚ healthy

done so by accident. Phosphorus was no different. This substance came about in 1669 when a German physician named Hennig Brand boiled‚ filtered and processed many gallons of urine. As disgusting as this method was‚ he conducted the experiment in hopes to distill salt by evaporating urine! In the interim‚ he generated a white substance that glowed in the dark and burned brightly‚ hence Phosphorus. The urine-burning method is not necessary any longer. We can collect phosphorus from phosphate rock

CUSTOMISED FERTILIZERS Rural Marketing Submitted By Kiran S. Ahirrao Roll No. 1006 Customized Fertilizers 1. What is Customized Fertilizer? Ans: Customised Fertilizers are combination of micro nutrients like sulphur‚ zinc‚ boron added to the key items such as urea and diammonium phosphate (DAP) and potash‚ in a proportion that suits specific crops and soil patterns. A fertilizer formulated according to specifications that are furnished by/for a consumer prior to mixing‚ usually based

mineral that I chose for his week’s assignment is phosphorus. Phosphorus is the second most ample mineral that is found in the human body. It flows all throughout the body‚ but more than 80% combines with calcium. The 80% that combines with the calcium is used for our bones and teeth. Phosphorus plays many major roles in our bodies. One of the roles that it has is that it is part of the DNA and RNA of every cell in the body. This is why phosphorus is important for growth and renewal of our tissues

Kayla Tucker Cycles Project In this paper i will be describing the different cycles that we have learned about. There are five cycles that are constantly happening around us. There is the water cycle‚ phosphorus cycle‚ nitrogen cycle‚ carbon cycle and the sulfur cycle. The water cycle is the first one i will be talking about. It is a continuous cycle and the water goes from liquid state to a gas state over and over again. It begins in a process called evaporation which is “the process of

(UPDATED) IN a report released yesterday‚ the Senate Blue Ribbon Committee and the Committee on Agriculture and Food said President Gloria Macapagal-Arroyo should be held accountable for the mismanagement of the P728-million fertilizer fund. The committees reported that testimonies showed the fund "was indeed used to assure her victory in the 2004 elections." In 2005‚ the PCIJ reported that the Department of Agriculture released nearly P3 billion during the 2004 campaign and was diverted to
