The activities related to the production and breeding of plants, their packaging and sale and distribution, the production and distribution of products and pesticides, the maintenance and sale of seedlings, seeds and roots, etc. are the main services that agricultural service companies provide.
p>Factors Affecting Agricultural Services
Agricultural services are effective natural factors and human factors. Natural factors include:
soil The type of soil definitely affects the growth of plants. The soil that is suitable for agricultural services in Tehran is usually composed of sand particles, soil and clay. A soil that causes more plant growth is called fertile. Soil fertility actually means the ability of the soil to grow plants that directly or indirectly contribute to the production of human food. The fertility of the soil depends on several factors, these factors include the presence of salts, water, acidity or alkalinity of the soil, as well as the presence of microscopic organisms in the soil.
Weather Each product needs its own climate. For example, cotton cultivation requires a humid climate, but pomegranates are cultivated in dry climates and dates in hot regions. Sometimes the areas with salty soil are not considered as agricultural service areas in Tehran, but even in those areas, crops with salt-resistant cultivars can be grown. And sometimes by building a greenhouse in areas with bad weather or in winter, good crops can be produced. In general, it is a good area for agriculture that, in addition to sufficient light, has soil rich in useful minerals and suitable climate. All of this depends on the type of product, its compatibility and resistance.
Water
In dry areas like our country, irrigation water is usually of poor quality. The meaning of water quality is its suitability for consumption. Water is used in agriculture, gardening, drinking and industry. Therefore, as long as the water is suitable and desirable for gardening and growing ornamental plants, it has the right quality. The dangers caused by salinity or sodicization of the soil can be easily predicted from the quality of water and based on the amount and type of salts in it. Therefore, water should not be used in irrigation projects without conducting quality tests.
