There are many types of market construction which are perfect competition, pure monopoly, monopolistic competition and oligopoly. The market construction of Agriculture is perfect competition and sometimes referred to as pure competition. Agriculture house is a perfect competition because it market construction characterized by a big figure of houses so each of the house in perfect competition produces an undistinguished per centum of entire market end product and therefore that no individual house can act upon or command over the governing market monetary value. ( Geoff Riley, 2006 )
Besides, the agribusiness merchandise is said to be standardized or homogeneous. Its agencies that, agribusiness merchandise is a merchandise where purchaser can non distinguish in footings of quality, packaging or labeling. Therefore, in agribusiness market clients do n’t care which specific house they buy from because it is perfectly indistinguishable. Therefore, the houses can non bear down different monetary values for the same merchandise in the market. ( AmosWEB Encyclonomic )
Besides that, There are freedom of entry and exist from the market in perfect competition. This type of market is executable in the long tally and no house will rule the market and evict other house. ( Geoff Riley, 2006 )
Furthermore, each house ‘s merchandise supplied to the markets that are prefect replacements for the merchandise of others houses, so the demand for each house ‘s merchandise is absolutely elastic. Therefore, the houses in the perfect competition have no power to put the monetary value they have to sell the merchandise at the traveling market monetary value. This type of house are said to be monetary value takers. ( AmosWEB Encyclonomic ) As a monetary value taker, single houses in perfect competition will sell their merchandise at the equilibrium monetary value. This can be shown in both figure 1a and figure 1b.

At the equilibrium monetary value, the measure demand and quantity supply of the market is balance. The equilibrium monetary value can be shown in figure 1a, where the supply and demand curve intersects with each others. The equilibrium monetary value is at P* .
At any monetary value below P* , the market deficit of the merchandise would be. At this monetary value the measure demand is higher than measure supply therefore it will causes extra demand in this merchandise. Due to the merchandise deficit, the purchaser would offer among themselves for the limited supply and monetary value would lift to extinguish the deficit. ( Grey Parry and Steven Kemp, 2000 ) . Conversely, if the monetary value is above the P* , the market excess of the merchandise would be. Therefore, it will do extra supply in this merchandise. Sellers will desire to extinguish the excess by take downing monetary values. That is because, when the monetary value falls, the measure of demand would lift to extinguish the deficit. ( Grey Parry and Steven Kemp, 2000 ).
When either supply or demand alterations, the equilibrium monetary value will alter. As shown in figure 2a below, the addition of nutrient demands from D1 to D2 do the both monetary value ( P1 to P2 ) and measure sold ( Q1 to Q2 ) to increase. At the old equilibrium monetary value of P1, measure demanded will now greater than the measure supplied. Therefore, the extra demand will ensue the measure supply motion along the supply curve to a higher equilibrium monetary value where the measure of demand and supply is one time once more in balance. A lessening in demand for nutrient would hold the opposite consequence, the equilibrium monetary value will diminish and the measure besides will diminish. ( Grey Parry and Steven Kemp, 2000 )

Bio-fuel production addition
Furthermore, the recreation of nutrient for doing bio-fuels has lead to increased demand for bio-fuel natural stuff, such as wheat, soy, corn and so on. Therefore, the increasing in biofuel production doing less nutrient available for human ingestion and the monetary value of nutrient harvests were increase dramatically. The most clearly illustration are the usage of maize in the United States for the production of biofuels. In the approximately 25 to 30 % of maize end product in the US is used for ethanol biofuels. ( CNET News, 2008 ) Biofuels have forced planetary nutrient monetary values up by 75 per cent and these monetary values are higher than the antecedently estimated, a survey by the recent study of World Bank ( Sumanjeet Singh, 2009 )
As shown in figure 2b below, when the supply of nutrient addition from S1 to S2, the nutrient monetary value will fall from P1 to P2 and the measure demand will be motion along the demand curve to a new equilibrium monetary value where the supply curve intersects with demand curve. Finally the new equilibrium monetary value and measure will P2 and Q2.

Natural catastrophe
First and first, that can non denied that the natural catastrophe conveying a earnestly influence on the nutrient production. The worst drouth happened in Russia last twelvemonth damaged a mostly figure of wheat harvest and do the Russian authorities to discontinue grain export for the twelvemonth. Seriously deluging in Australia besides amendss wheat harvests and causes some of the harvests were downgraded for usage merely as carnal nutrient. Consequently, the wheat harvests were faced deficit in the past twelvemonth and do the monetary value of grain nutrient has risen aggressively. ( Dr. Grary Peters, 2011 )
Negative clime alterations
Beside that, the word agribusiness providers were significantly decreased due to the planetary heating. Therefore, in the planetary heating period will ensue in extra monetary value addition for the most of import agricultural harvests such as rice, wheat, corn, and soya beans. Harmonizing to the International Food Policy Research Institute showed in December, it states that the planetary heating will increase the monetary value of maize, wheat and rice by at least two-thirds by 2050. ( Bloomberg, 2011 ) Beside that, harmonizing to the Integrated Regional Information Networks, IRIN, it province that within the following four decennaries maize monetary values could lift by up to 131 per centum due to the planetary temperature and some of the African husbandman might hold to give up agribusiness if the conditions are acquiring hotter.
