Soil test values are reported in parts per million (ppm), which represents 1 milligram of extracted nutrient for each kilogram of soil. If you want to estimate the value in pounds per acre, you can simply multiply the ppm value by two. For example, a potassium soil test value of 193 ppm equates to 386 lbs/acre of "exchangeable K" in the top six ...
Jun 6, 2024 · Some plants like garlic, asparagus, beans, brassicas, and alfalfa tolerate slightly alkaline soil (7.0 to 8.0), but most plants struggle to grow with a super high pH. This quick guide makes it easy to understand these numbers: High pH = above 7.0 = alkaline = add sulfur if you need to lower the pH. Neutral = 7.0.
Understanding the Soil Test Report Page 2 of 7 Soil Test Results pH The soil’s level of acidity, or pH, affects the availability of nutrients to the crop. • The pH scales ranges from 0 to 14, where 7 is neutral, below 7 is acidic, and above 7 is alkaline or basic. • Each whole unit (1.0) is a ten-fold difference in the level of acidity.

Most sandy soils have calcium concentrations below 400 to 500 parts per million (800 to 1,000 lb/acre), while clayey soils usually test above 2,500 ppm. Normally, the higher the calcium level, the greater the soil clay content. Recent limestone applications may result in higher calcium levels.

Dec 12, 2016 · It is generally assumed that the following amounts are required (above crop removal) to move soil test values up by 1 ppm: 35 lbs/acre P 2 O 5 and 20 lbs/acre K 2 O. These values are guidelines and can vary depending on a variety of factors, including soil type. In some situations, the amount of nutrient required to raise soil test values may ...
The primary goal of soil testing is to inform efficient and effective resource management. Soil testing is the most accurate way to determine lime and nutrient needs. Soil testing is also useful for identifying contaminated sites (e.g., elevated levels of lead). The results provided on your soil test report reflect the properties of the sample you submitted and the testing procedures used by ...

Soil testing is a quick and inexpensive way to determine the nutrient status of your soil. It helps to determine how much (if any) lime, fertilizer, or other amendments are needed to optimize your soil for plant growth. The first step in understanding the information you are receiving and how you can best use it, is to understand the limitations of the system.
