Master Soil Test Kit: We provide Available Nitrogen, Phosphate, pH, Organic Carbon, Available Potassium Soil Test Kits in a one box that is Master Soil Test Kit evaluate the fertility and nutrient status of soil for providing an index of nutrient availability or supply in each soil. Determination of acidity, salinity, and alkalinity problems. To provide a recommendation on the amount of manure and fertilizer based on soil test value and according to crop we are introducing Master Soil Test Kit is having various types of parameters like 4 parameters, 5 parameters, 6 parameters and up to 8 parameters according the requirements.

Potassium (K) is an essential nutrient for plant growth. It's classified as a macronutrient because plants take up large quantities of K during their life cycle. Minnesota soils can supply some K for crop production, but when the supply from the soil isn't adequate, a fertilizer program must supply the K. Potassium (K) is the most abundant inorganic cation, and it is important for ensuring optimal plant growth (White and Karley, 2010). K is an activator of dozens of important enzymes, such as protein synthesis, sugar transport, N and C metabolism, and photosynthesis.

Soil pH is a measure of how acidic or alkaline soil is. It's important for plant growth because it affects the availability of nutrients in the soil.  Soil pH scale  pH 7: Neutral pH above 7: Alkaline pH below 7: Acidic pH 4.0–5.0: Strongly acidic Most soils have pH values between 3.5 and 10. In higher rainfall areas the natural pH of soils typically ranges from 5 to 7, while in drier areas the range is 6.5 to 9. Soils can be classified according to their pH value: 6.5 to 7.5—neutral.

Available nitrogen in soil is the amount of nitrogen that plants can use, and it includes nitrate (NO3) and ammonium (NH4). The amount of available nitrogen in soil depends on the type of soil, the amount of organic matter, and other factors. Nitrate-nitrogen (NO3-N) measures the amount of available nitrogen in the soil that can be absorbed immediately by plants. The amount required in the soil for specific crops varies from crop to crop, but in general the levels should not fall below 10 mg/kg and should not exceed 50 mg/kg.

Phosphorus is the second most important crop nutrient after Nitrogen. It is an essential macronutrient that plays important role in all crop biochemical processes such as photosynthesis, respiration, energy storage, transfer, cell division, cell enlargement and nitrogen fixation. It is also important in seed germination, seedling establishment, root, shoot, flower and seed development. Despite its importance in crop nutrition, availability of the nutrient in soils for plant uptake is limited by several soil factors. The factors include: soil pH levels, clay mineralogy, organic matter, free iron and aluminium, calcium carbonate, soil temperatures and availability of other nutrients among other factors. Availability of phosphorus for plant uptake can be managed by adoption...

Soil organic carbon is the basis of sustainable agriculture. Farmers are interested in retaining and increasing soil organic carbon for individual fields in order to improve soil health and yield. One of the main reasons behind this is the ability of soil organic carbon in maintaining the soil fertility. SOC improves soil aeration, water retention capacity, drainage, and enhances microbial growth. As carbon stored in the soil is increased carbon is “sequestered” (long -term storage) and risk of loss of nutrients through leaching and erosion is reduced. When the amount of carbon in the soil is increased it reduces the amount of carbon dioxide present in the atmosphere which provides a...
