Agriculture and environment are closely connected with each other. Crop yields and animal productivity depend on soil and climatic conditions of the region in which they are grown. When environmental conditions are favorable, crops grow and develop well and produce high yields.
At present agriculture is not so dependent on the environment as in the past. (Man can improve the conditions under which crops are grown. The conditions can be improved by using irrigation and drainage, by applying fertilizers and different chemicals such as herbicides and insecticides and by some other practices. The environmental factors do not only affect agriculture, but they are also affected by the agricultural activity. Mineral fertilizers and chemicals used by farmers accumulate in the soil and in plants and may become harmful for people. Thus, the farmers have to solve two problems. On the one hand l they are to improve and intensify agricultural production and on the other hand 2 they are to minimize the effect of agriculture on the environment.
Some other important intensive technologies are the development of better high-yielding varieties of crops, the application of most effective cultural practices, the breeding of better farm animals, the control of weeds, insects and diseases. All intensification factors must be used in such a way as not to damage the land which is the basis of agriculture.
