RICE GROWING IN TANZANIA AND CHINA.
Rice is one of the staple food, and it is very important as a source of food, rice needs heavy rainfall over 1500 mm per year and hot climate. Rice is grown in river valleys. In Tanzania , rice is grown in Kilombero, Wami valley, Kilosa, Ulanga, Mbeya, Rufiji river basin, Usangu plains, Morogoro, Shinyanga and Iringa.
Rice produced in Tanzania is mainly consumed within the country.
China is the country found in the continent of Asia. The capital city of China is Beijing.
China is the main producer of rice. The northern region of china does not grow rice because of its very mild climate but the southern region of china grows much rice and has many rice plantations. These plantations are flooded to help the crop to grow well. China exports its rice because it produces a high yield of the crop. Other countries in Asia which are main producers of rice are Burma, Thailand and India
MODERN AGRICULTURAL TECHNOLOGIES USED IN CHINA AND GHANA.
-Tractors are used
-Seeds are planted by machines
-Farmers use combine harvesters, this is a machine that harvests grain crops.
-Irrigation scheme is used example construction of Akasombo Dam on the river Volta in Ghana enhanced the use of irrigation in the country
-The use of chemical fertilizers and pesticides is practiced in China and Ghana.
-Deforestation due to clearance of land for agriculture.
NEGATIVE EFFECTS OF AGRICULTURAL ACTIVITIES
-Chemical fertilizers can run-off into water in rivers , streams and lakes hence water pollution.
-Air pollution due to burning of vegetation for preparing farms for agriculture.
-Water sources are destroyed.
METHODS OF MANAGING NEGATIVE EFFECTS OF AGRICULTURE.-farmers should practice contour ploughing. This is called terracing system which helps in soil and water conservation
terracing means ploughing on a slope by breaking it into many step-like benches which are almost flat. This prevents rainwater from causing erosion of topsoil.
-Crop rotation should be adopted. This is growing crops of different types in the same area. This will maintain soil fertility
-Land fallowing system should be adopted
-Farmers should be discouraged to use excessive chemical fertilizers. They must use natural fertilizers such as compost manure and animal manure.
-Leguminous plant like beans, groundnuts should be planted together with other crops. These plants contain roots that have ability to add nutrients to the soil.
