By employing various technologies and techniques, production can be maximized (use of fertilizers, genetic developments, irrigation, mechanization), while other methods are used to minimize loss of crops through pests and weeds (including use of pesticides, fungicides, herbicides, mechanical weeding, biological control). The purpose of agriculture has traditionally and primarily been to meet the demand for agricultural products, mainly food, but also raw materials for fiber manufacture. Although the underlying purpose for agriculture has not changed, the nature, structure and ways in which these demands have been met have changed greatly over the last few decades, and will continue to do so. Changes have resulted from a variety of factors. These include: patterns of consumption of agricultural products; food distribution and processing; genetic development of agricultural production and other technological developments; the progressive globalization of agricultural markets, and the influence of national and international agricultural products. The failure of European agriculture to meet demand during World War II and shortly after, made security of food production the main objective of agricultural policy from the late 1940s. Every country in Europe has encouraged its farmers to produce more food through a variety of mechanisms, including price support, other subsidies and support for research and development. Text 2: The EU Common Agricultural Policy The EU Common Agricultural Policy (CAP) is the single most influential agricultural policy in Europe. Before its 1992 reform, the heart of the policy, in most cases was the system of guaranteed high prices for unlimited production. These guarantees encouraged surpluses of produce such as cereals, beef, dairy products (milk) and wine. Quotas on some products were introduced during the 1980s but the purpose of these was to maintain guaranteed high prices. Key to Exercises Exercise 1: 1. C 2. D 3. A 4. B 5. A 6. D 7. A 8.

Agriculture is important for people as it is the only way the meet the increasing need for food production globally. 2. Some of the common methods farmers usually use to maximize their crops are the use of fertilizers, irrigation, mechanization and developments in the field of genetics. 3. Crop production loss can be attributed to a number of factors, the most common of which are pests, weeds and fungi. 4. To some respects, it is. As Greece is an EU member state, its agricultural policy has to comply with policies established by EU in terms of price and food quality produced. 5. Their main objective was to secure a surplus of food production for all nations around the globe. Unit 2 Soil Structure Everything in agriculture depends on the soil and its productivity. If we wish to continue to live, we must look after our soil and understand it fully in order to produce the most and the best from it. Soils are arranged in layers or strata just like a sandwich. These strata are called horizons and a mature soil normally has A, B and C horizons. To see the whole soil as it really is we must look at a soil profile. The A horizon is the covering layer. It is also called the surface soil, topsoil, or plow layer. It varies from almost nothing to 12 inches deep, according to the nature of the subsoil underneath and the depth of cultivation. It is darker, because it contains organic matter and it is easy to work. It is the real living soil; plant growth and crop production depend on the condition of the shallow layer of the soil. The B horizon is the next layer down and is called the subsoil. It consists of the rock partly broken down and altered in some way by action from the top of the soil. There is usually no organic matter in it and it is like dead soil. The roots of large plants usually grow in the subsoil. In mature soils the A and B horizons are called the solum. Beneath the solum we have the C horizon which is the basic or parent material from which the solum has normally been formed. It may be of sandstone, limestone or other hard rock, chalk, sand, silt or clay. There are though some expectations in the structure of profiles. An example is the regosol, a group of soils without horizons, which have developed from deep loose rock or from soft rocky deposits. When we speak of an ABC soil, we mean a mature soil, one having three well defined horizons. An AC soil is usually young or immature. Text 2: Soil Profile Information Soils are three dimensional bodies that carry out important ecosystem processes at all depths in their profiles. Depending on the particular application, the information needed to make proper land management decisions may come from soil layers as shallow as 1 or 2 centimeters, or as deep as the lowest layers of saprolyte. For example, the upper few centimeters of soil often hold the keys to plant growth and biological diversity, as well as certain hydrologic processes. On the other hand, it is equally important not to confine one’s attention to the easily accessible ‘topsoil’, for many soil properties are to be discovered only in the deeper layers. Plant growth problems are often related to inhospitable conditions in the B or C horizons that restrict the penetration of roots. Key to Exercises Reading Comprehension Exercise 1: 1. T 2. F 3. T 4.

Soil is important in agriculture as it its quality determines crop the quality and amount of crop production. 2. A soil profile is its identity card as it describes its layers as well as its basic sub-components. 3. A mature soil is made up of three well-defined horizons, i.e. A, B and C while a young or immature soil is usually an AC soil. 4. Regosol can be considered an exception from the usual soil profiles as a group of soils without horizons.
