So too much of certain nutrient can have a large affect on the plant (Sims, Pastor, Lee, Dewey 2011). Today, agriculture and the food industry have a huge part in our society’s development, as it has become an essential part of our economy. The soil farmers use to grow their plants contain nutrients to help the plants grow. Since nitrogen is needed in large quantities by the plant, it is most frequently used as fertilizer. The need for nitrogen depends on the plant.
Soil pollution is when either a natural or chemical product is put into the soil and makes it unbalanced. This also affects the health of plants and other living organisms living on the soil. Soil pollution puts a halt to food production and adds hazardous factors to this industry too. How is this happening though? Farming is one of the top contributors to soil pollution.
But fertilisers can also be potentially hazardous to the environment; they can pollute local water supplies, harm humans and animals and can add to the amount of volatile gases being added to the atmosphere. Firstly fertilizers are potentially good for the environment in ways that they improve the soil structure and nutrient content, this therefore improves plant growth. Fertilisers are needed to allow a farmer to have maximum productivity in the crop that they are growing. So they are vital for economic reasons to allow the most productivity the land can give, (high yield) so the most money can be got from selling the high yield amount of crops. Also fertilisers help the condition of the plants to be top condition by providing them the first hand nutrients, which are vital for good growing that may not already be in the soil.
Furthermore, if we do not practice sustainable agriculture, our soil has more of a chance to become more vulnerable to droughts and flooding, possibly increase a risk for more global warming, and be less resistant towards antibiotics and pesticides. Having a sustainable agriculture today is vital to how todays farming is done, and changing to make it more effective is the only way we can continue to clothe and feed our increasing world population.

Although there are many practices already in place that will decrease the pollution, increase productivity, and save farmers money in the long run, the farmers are careful to change practices. Sedimentation The most prevalent source of agricultural water pollution is soil that is washed off of fields. These fields have been treated with fertilizers and pesticides, which over time have accumulated heavy metals that are then transferred to lakes and streams. The excess particles cloud the water blocking vital oxygen and sun for the aquatic plants. Nutrients Farmers apply nutrients such as nitrogen, phosphorus, manure, and potassium in the form of fertilizers to produce a better product for the consumers.
Chemistry is used to prepare the soil, fertilize the plant, protect it and even distrbute it. Agriculture can be a complicated process. To obtain the best results and the best production it is very important to have good soil. In a lot of cases that is not always the case and farmers really have to depend on the use of chemistry to come up with the best products that will allow the soil used to be fertile. Preparing the soil thru the use of chemically enhanced products really allows crops to grow more abundantly.
Farming is currently a main source of water pollution. Pesticides run-off from agriculture land also lowering drinking water quality and harm water-based wildlife. Environment mostly affected by agriculture because it is the only place for agriculture activity. However, environment also get benefit from agriculture activity which is prevention of global warming because agriculture activity such as planting keep environment cool because it has power to cool environment by process called transpirations. Nowadays, world population growth increase rapidly and about to reach the highest capacity, this will cause increasing in demand for production of food.
For example, farming techniques which use earth-moving machines can appear effective for crop production, but will eventually damage the topsoil which thereby decreases crop productivity (McLaren, 1990). Erosion is a substantial contributor to deterioration of soil quality. Flood and furrow irrigation use a high influx of water to immerse the crop area.
Most importantly, nitrogen is one of the most important elements because it is the base of the food web and it is involved in a fundamental cycle. Free nitrogen in the air is absorbed by plants and converted to plant proteins. It is then eaten by animals that convert it to animal proteins and return it to the soil as nitrogen waste. Then bacterial action causes the nitrogen compounds to become free nitrogen again. Thus, plants need nitrogen to survive, the animals need the plant proteins to survive, and we in turn need animals and plants to survive.
The controversy regarding this practice occurs as it is believed to contribute both negative and positive implications and dangers, not only to oneself but the environment as a whole. Genetic engineering increases the agricultural economy, the yields of agricultural produce, and also causes negative effects on the ecosystem. Genetic engineering enhances plant resistance to drought, salinity, disease, pests and herbicides. The aim is to try and enhance the growth, productivity, nutrient value, and chemical composition of the plants. Chemicals are constantly being developed or improved to enhance the competitiveness and adaptability of crops, and to kill the parasites and weeds which plague the agricultural sector.
