What is a soil analysis report?
What is a soil analysis report?
Soil testing is used to assess what soil nutrients are present or may be needed for optimum plant growth and yield potential. The results from a soil test list the concentration of each measured nutrient, an interpretation value (low, optimum, and high), and recommendations for amendments or nutrient application.
How do you analyze a soil report?
How to Read a Soil Analysis Report
- Soil pH. This a measure of acidity or alkalinity of your soil on a scale of 0 to 14, with 7.0 soil pH being neutral.
- Buffer pH. This is not a characteristic of the soil.
- Soluble Salts.
- Excess Lime.
- Organic Matter (OM)
- Cation Exchange Capacity (CEC)
- Percent Base Saturation.
What are good soil test results?
Test results higher than 40 and 220 for phosphorus and potassium, respectively, are sufficient for most crops. Calcium is associated with soil pH. Soils with a good pH generally have adequate calcium, and soils low in calcium generally need lime. A test result of 500 or higher is adequate.
What is the purpose of soil analysis?
A soil analysis is used to determine the level of nutrients found in a soil sample. As such, it can only be as accurate as the sample taken in a particular field.
What can a soil test tell you?
The soil test will tell you the percentage of organic matter you have in your soil and will “credit” you a certain amount of nitrogen for it. This will minimize the risk of applying excess nitrogen which might then wash out of your soil and into surrounding waterways.
What is a good CEC for soil?
CEC is reported in units of milli-equivalents per 100 grams of soil (meq/100 g) and can range from below 5 meq/100 g in sandy, low organic matter soils to over 15meq/100 g in finer textured soils and those high in organic matter.
What is P and K in soil?
Soil Tests Are Key Together with nitrogen, P and K form the Big Three of crop nutrients. P plays a crucial role in plant processes like photosynthesis, respiration, and energy storage and transfer. K benefits include increased root growth, improved drought tolerance, and enhanced photosynthesis.
What is the importance of soil pH in soil analysis?
The study of soil pH is very important in agriculture due to the fact that soil pH regulates plant nutrient availability by controlling the chemical forms of the different nutrients and also influences their chemical reactions. As a result, soil and crop productivities are linked to soil pH value.
What are the types of soil tests?
Types of Soil Tests for Building Construction
- Moisture content test.
- Atterberg limits tests.
- Specific gravity of soil.
- Dry density of soil.
- Compaction test (Proctor’s test)

Is a high CEC good or bad for plants?
Significance of CEC and BS A soil’s CEC affects fertilization and liming practices. For example, soils with high CEC retain more nutrients than low-CEC soils. With large quantities of fertilizers applied in a single application to sandy soils with low CEC, loss of nutrients is more likely to occur via leaching.
What two factors are most important for soil having a higher CEC?
Factors influencing the CEC include the soil type, the soil pH and the soil organic matter content. Soils are made up of sand, organic matter, silt and clay particles. Soils with high sand content have low holding capacity for cations compared to clayey and silty soils.
