In agriculture a soil test is the analysis of soil samples to determine nutrient and contaminated content, composition and other characteristics such as acidity or PH, EC. A soil testing can determine fertility the expected growth potential the soil, which indicates nutrient deficiencies, potential toxicity from excessive fertility and inhibition from the presence of non essential trace minerals. The test is use to mimic the function of roots to assimilate minerals. The expected growth rate is maximum or high. Soil analysis including analysis of macro and micro elements, Nutrient analysis for crop production and Diagnosis plant culture problems.

Test water to be used to be used for irrigation by reputable laboratory to determine the quality of water for irrigation, choice of fertilizer for optimum plant growth and to minimize and risk of discharging pollutants to surface or ground water. At minimum test for total alkality and solubility. Monthly analysis is recommended for new new water sources Water quality testing is important because it indicates contaminants and prevent water born disease. Essential water quality testing is make sure that water safe and meets local and international water std. That's why all water for human and animals used should be tested safely., Water is one of the most important inputs essential for the production of crops. Water quality is important for many agricultural uses such as Livestock, Watering, Irrigation and spraying. Plants need it continuously during their life and in huge quantities. Water analysis required for quality of water or drinking purpose, food preparation, Poultry, Agriculture and Green houses

Plant tissue analysis is normally used to determine the reason or poor growth or to check an accumulation of mineral and elements to toxic plants. The nutrient content of plant can be assessed by testing a sample of tissue from plant i.e. Leaf and Petiole. These tests are important in agriculture since, fertilizer application can be fine tuned it the plants nutrient status is known. Plant tissue sampling has some crucial elements such as timing, growing stage, plant part and the no. of leaves required for testing and sampling varies between crop types. Leaf and Petiole Analysis for Agriculture, Horticulture and Green house plant. Available nutrient of plant and detection of elements.
