Introduction Do you know that some of the food we eat is produced by farming? Nowadays, although there are very few farmers in Hong Kong, farming is still very important. There are two main types of farming methods. Do you know what are they? They are scientific farming and organic farming. We will introduce and compare them, and find out which one is better. Rabbit kept by organic method 3 4. Scientific farming They are to improve the water supplies, use the machine, use the chemicals and improved the species. The purposes are to increase the farm outputs, decrease the work of the farmers. Organic farming Organic farming is an agricultural method of plantation and feeding poultry with natural principles. Organic farmers avoid artificial fertilizers and pesticides. They will make use of crop rotation and discard recycling to keep the soil fertile. This will balance the interest of beneficial and harmful species so as to the growth of healthy crops. Based on the traditional wisdom, organic farming also makes use of newly-found scientific knowledge and advanced research results, such as anti-pest and anti-disease new species, new natural enemies and new green fertilizers, to produce healthy crops and ensure the well-being of human and the Earth. 4 5. Advantages and Disadvantages of scientific farming Advantages Disadvantages Farm works can be done effectively Have to open more farmland Can employ less farm labour May cause soil erosion and soil degradation Can increase the farm output May lead to desertification Can grow more crops in better Have to use more fuel, may cause quality air pollution Can make the plants easier to plant May lead to salty soil May affect our health Can make the plants more nutritious method 5 6. Advantages and Disadvantages of organic farming method Advantages Disadvantges Can recycle the waste The cost is expensive Farming without using chemical More land is used pesticides Have more nutrition Less pollution Better taste Organic farming plant 6 7. Comparison between organic farming and scientific farming Organic farming Scientific farming Pollution Less More Price More expensive cheaper Nutrition More Less Taste of the product better More insipid A tool to keep the animals and inserts away from the plant 7 8. Our choice of farming method Although scientific farming is cheap, it causes more pollution. It will make our living environment worse and worse. The nutrition of the food will be less also. If we eat the food which is farmed by scientific method, we will be unhealthy. And the taste of the food which is farmed by scientific method is insipid also. On the other hand, although organic farming is expensive, it causes less pollution. The nutrition of the food will increase also. The taste is better too. So, we think organic farming is better than scientific farming. Organic fertilizer 8 9. Feeling After the field trip, I learn many things about farming. I am interested in farming. Although farming is not common in Hong Kong, it is related to our daily life. Besides, we also learn how to farm like a farmer. It is quite interesting. I think farming is very hard and difficult. I wonder how farmers can farm every day. I really appreciate them. I seldom have an outing with my other classmates. This field trip is a great experience to me. Chow Cheuk Yin, Tommy Most of our projects don’t need to go out to investigate on the spot, but only find information on the net. This project requires us to investigate on the spot so I have learnt the skill to find information on the place that we investigate. And I found that a drop note is also very important. It can help you to listen and analysis the data. I hope that I can have more chances to know about farming because it is so interesting. Fung Sheung Chi, Simon We always find information on the Internet. It is a rare experience to do a project with investigating on the spot. In the farming part of the trip, I feel the great effort the farmers have paid. Now I would not waste any crops of the farmers. I also know a lot of things about organic farming. The 9 10. trip make me became more interested into this kind of farming method. I hope I can have more chances to have this kind of trip. Man Wing Ho, Victor 10 11. Geography, gives me a very boring feeling. Before this trip, I thought Geography is just study the textbook and memories everything. But after this trip, it totally changes my feeling of geography. I have never had this kind of outing before, so I thought this was a waste of time because it took away my P.E. lessons. However, after this trip, I learnt a lot of things that cannot be found in textbook, like I could have firsthand taste of farming. I did not think about how hard the farmers are. But now I know that the farmers are very diligent in their work. I just farmed for a while, it was quite tired to take the heavy tools for a long time. So we should respect farmers. And we should also treasure our food, it is not easy to grow, it needs a lot of time. At last, I also admire the wisdom of the farmers. They think of different methods to protect the crops. It is the things that I learnt from this trip. I hope the school can hold more outing in the future. Hui Ying Kit, Steven Before going to the field trip, I think farming is easy. But after going to the field trip, I think it isn’t. I know farming is very hard and difficult. The hoe is very heavy, the weather is hot… so I think farmers are very great, they can work under sun for a long time in summer and farm with a heavy hoe without feeling very tired. We must thank the farmers for their hard-working of farming for us. During the field trip, I also learn a lot about organic farming. Many of them cannot be found on textbooks. So I think this field trip is very 11 12. useful to us. I hope we can have more chances to have outing like this field trip. Wong Kin Kon, Tony 12 13. Acknowledgement Ann Lee (The tutor) 13
