E-Learning & Certification of soil and plant tester, has been created to fully familiarize people with soil and plant tester. soil and plant analysis tester in the field Agricultural Engineering and the qualification Such as speeding up and facilitating the measurement of phosphorus and potassium, saving in the use of chemical fertilizers, helping to prevent environmental pollution, determining soil fertility, improving soil texture, speeding up and facilitating the measurement of organic matter, percentage of lime, calcium and magnesium. existing in the soil, using more accurate methods to measure elements, applying more correct fertilizer recommendations, determining plant fertilizer needs, etc. This qualification is related to agricultural engineering jobs in the fields of soil science, agriculture, crop and fertilizer management, people working in the agricultural and natural resources research center, people working in soil analysis centers and laboratories, fertilizer advice consultants.

Necessity of soil and water testing:

Investigating soil characteristics as an environment for plant growth and establishment, as well as access and provision of nutrients, is essential. Since the plant absorbs most of the nutrients it needs from the soil, determining the status of these elements in the soil is very important for the successful production of the product. Obviously, the amount of required elements will be different based on the type of plant and soil conditions and region. Also, the use of large amounts of agricultural fertilizers without considering the conditions of the farm, spending a lot of money and causing pollution, causes farmers to switch to a more reliable method. Conducting soil testing and examining it by experts leads to reducing costs as much as possible, increasing the quantity and quality of the product, as well as maintaining the health of the soil and the environment. In addition, in situations where the soils have a large amount of lime, high salinity and alkaline or acidic pH and have faced problems in agriculture, examining the condition of the soil through soil testing with the opinion of experts can play an effective role in managing and improving production conditions. be Also, the importance of investigating the characteristics of irrigation water due to its effect on soil conditions in the long term and the difference of different plants in response to salinity and other water characteristics is not less than conducting soil tests.
