Introduction

'How different methods of farming provide plants with what they need'- comparing methods of farming including Small-scale organic farming. Large scale arable farming. Hydroponics farming How the plants get their nutrients from this method of farming. Small-scale organic farming. Organic growers rely on the quality off soil and the natural organic matter within free from contamination. Nitrogen is naturally formed my the breaking down of organic matter and will be found in the soil naturally but to supplement this organic growers might add dry blood meal a rich source of nitrogen. Other important minerals including phosphorus are found in cottonseed meal. All these organic alternatives are natural and can be sourced locally; one of the most common 'organic fertilisers' is manure, animal waste, rich in nutrients and minerals. The water source for the plants is usually left to the rain however during dry periods people will water the plants using a watering can or hose. ...read more.

Middle

The main difference being that the nutrients and minerals are all found within the water. A soil system is difficult to keep in control due to the to poor soil structure or unfavourable soil pH value plants nutrients are frequently not presented. However a hydroponics grower has the freedom to regulate the nutrient solution. This gives the grower more control. Hydration systems within the green house can also control the amount of water given to the plants. Artificial lighting ensures the perfect growing conditions. How optimum levels of providing the plats with nutrients, sunlight, C02, minerals, water are achieved and how pesticides and diseases are kept at bay. Crop rotation Arable farmers and some small-scale organic growers will use crop rotation to get the most out of the soil. By using the same section of field to grow crops ear after year you exhaust the soil and the nutrient supply. ...read more.

Conclusion

Artificial fertiliser Synthetic fertilizers consist of various combinations of minerals and nutrients. Most fertilizers concentrate on providing nitrogen (N), phosphorus (P), and potassium (K) and are called NPK fertilizers. They contain compounds such as ammonium nitrate (NH4NO3); ammonium sulphate ((NH4)2SO4); potassium sulphate (K2SO4); and ammonium phosphate ((NH4)3PO4). Environmental issues concerning the different methods of farming. Many farming methods particularly in large-scale production have environmental concequences. Here is a table to show advantages and disadvantages of different methods and their effects on the environment. Method Advantages Disadvantages Small scale organic farming No harmful chemicals used Improves soil structure and nutrient content Large scale arable farming Harmful pesticides and herbicides used destroy wildlife Soil exhaustion due to planting density and over use Hydroponics No problems with soil exhaustion Requires high amounts of energy Clean Loss of habitat when constructing Water Pollution This occurs when chemicals from fertilisers contaminate a water source. This will effect animals using the water source for drinking or as a habitat Sources used include the following: http://www.small-farm-permaculture-and-sustainable-living.com/advantages_and_disadvantages_organic_farming.html www.allotment.org.uk/fertilizer/artificial-fertilizers. ...read more.
