Fertiliers organ Vs inorganic

Extracts from this document...


Fertiliers organ Vs inorganic To make sure we use our land efficiently to get as much growth from it as we can, we have chemicals such as pesticides and fertilizers to make sure farmers harvest a maximum yield each year, but how much do we know about these chemicals? There are two main types of fertilizers, organic and inorganic. Organic fertilizers are organic materials, mainly made of animal and plant wastes. Inorganic fertilizers are concentrated source of macronutrients. They are usually in powdered form, which can be added directly into the field. First of all, let us consider the advantages of using organic fertilizers. Organic materials can be made by farmers themselves as they can be produced from waste materials from cattle, i.e. from cow manure. Sometimes, farmers can fertile their land by having a mixed farm (gazing animals and growing crop at the same land). Animal waste can be applied to plant crops, making soil more fertile. This can also save farmers money to purchase chemical fertilizers elsewhere. ...read more.


As organic materials produce heat, in warm areas, organic fertilizers may warm up the field making the temperature too high for some crops to grow, lowering the growth rate and therefore the yield. In addition, fertilizers produced by livestock (urine and faeces) may be harder to dispose of, leading to the indirect increase of nitrate and other ions to the surrounding areas, which can pollute surrounding ponds and steams. Finally, more time and labor are needed to apply a given amount of nutrients into fields in comparison with inorganic fertilizers, as they are not in powdered form inorganic fertilizers are. As mentioned above, there is a slow release of nutrient due to microorganisms' activities. This can be an obvious disadvantage, as organic materials cannot supply sufficient nutrients to crops in a short period of time, so farmers would have to use inorganic fertilizers if there is an immediate need for nutrients. Inorganic fertilizers are the other major type of fertilizers used in the farming industry. ...read more.


In addition, inorganic fertilizers can also alter the soil PH, which disrupts the microbial environment even more. This causes the decline of the biodiversity of the soil-food web, making crops more dependent on chemical fertilizers, causing soil to be devitalized, which may lead to desertification as a result of pro-longed use of inorganic fertilizers. Damaging microbial life causes plants to lose their essential trace minerals, therefore the soil no longer has a wide range of nutrients. Furthermore, as inorganic phosphorous replaces calcium in the cell wall; crops become less resistant to insects and disease. Although this is overcome by using pesticides, the cycle continues making soil more toxic each time, causing severe problems to the environment. Although recently, there is a slight increase towards using organic fertilizers, as it is believed to be more environmentally friendly, both fertilizers have their own positive and negative factors. Therefore, whether a farmer chose to use organic, inorganic or even a combination of both fertilizers depends on many circumstances. However, organic and inorganic fertilizers both help significantly in increasing crop yield each year, and therefore are an essential tool in the food industry. ...read more.

  1. effects Concentration and Temperature on the Rate of Reaction

    It also shows that there is a positive correlation between concentration and reaction rate, as when concentration of potassium bromate(V) is increased, reaction rate increases. I could draw the line of best through the origin at point (0,0) as I know that if the concentration is 0M then the reaction

  2. The Chemistry oh Phosphorous

    Another property of white phosphorus is its glow-in-the-dark traits. When it undergoes oxidation due to exposure to air, light is produced, hence in the dark white phosphorus continues to glow. This property is called phosphorescence. Red phosphorus is a red powder and can be formed by heating white phosphorus to 280�c with a catalyst present.

    With the electrons they gain from that they reduce Fe3+ to Fe2+ to continue the cycle. The gold is now separated from the ore and its solution. The process for copper is very similar. The mineral chalcopyrite CuFeS2 (pictured) follows the two stages of being dissolved and then further oxidised, with Cu2+ ions being left.

  2. Organic and Inorganic Fertilisers

    Not all organic fertilisers are slow at releasing ions though. For a nitrogen deficiency dried blood is very fast acting and is good at providing a quick-short term boost. (The Organic Garden Book by Geoff Hamilton) Some Inorganic fertilisers also release nutrients slowly over time; they are called 'slow-release fertilisers'.
