    Soil test results may from lab to lab vary because several methods can be used to extract the nutrients from the soil sample when estimating the nutrient supplying power. Although the levels may be different, the interpretation (very low, low, medium, high) should be fairly consistent between reputable labs. Soil testing and applying only the soil nutrients needed to produce your yield goal can provide a significant savings in fertilizer costs. Nebraska research shows growers can save as much as $/acre for postponing phosphorus, potassium and zinc applications.

    **If soil test indicates high levels of phosphate and potash, omit from program and use nitrogen sources only. If soil test indicates phosphate and potash are needed, use a fertilizer containing each nutrient. March 15 to April to lb nitrogen (20% or more as WIN or a coated-nitrogen source*). Soil Testing Why Test Your Soil? Plants need food (nutrients) for healthy growth. Nitrogen, Phosphorus and Potash (N, P and K), play a vital role in plant growth just as vitamins, minerals, carbohydrates and protein do in our s: K.

    These include protecting soil structure, feeding the soil with nutrients from natural and local sources, and increasing the diversity and numbers of the microbes and other organisms that live in. of the manure to be valued, a recent soil test for the applica- tion area, recommendations for nutrients needed for the next and following crops, and current fertilizer prices. Determining Nutrient Value of Manure Manure or compost should be applied at or below the rate that meets the nitrogen (N) need of the next or current crop.

One of the difficulties in developing recommendations from nitrogen soil tests is our inability to accurately predict the rate of nitrogen mineralization. Hence, soil tests are not exact measures of available nutrients because of the difficulty in using a simple chemical extractant to evaluate the available nutrients for plants in a wide.

Soil pH and Exchangeable Acidity – One of the most valuable pieces of information you can get from soil testing is a measure of soil acidity. Soil pH is an indicator of the soil’s acidity which is a primary factor controlling nutrient availability, microbial processes, and plant growth.

The soil tests were run by different procedures, to provide examples from around the U.S. Interpretations of a number of commonly used soil tests—relating test levels to generalfertility categories—are given later in the chapter (see tables and ).

Many labs estimate the cation exchange capacity that would exist at pH 7 (or even. It will offer recommendations for both organic and synthetic fertilizer types, as well as a recommendation of how much fertilizer you should use to improve your soil at its current level.

For those new to soil testing, this is a great perk, and worth the money. Have a soil lab do a test for you: A complete soil test is a good investment because a soil lab can thoroughly analyze your soil. Here’s what you can find out from a soil lab’s test in addition to the pH level: Your soil’s nutrient content: If you know your soil’s nutrient content, you can determine how much and what kind of fertilizer to use.

I always recommend taking one when starting a new garden, or when garden health declines. If an essential nutrient is missing, garden and soil health will suffer. For best results, take nutrient tests in the late summer or early fall.

Submit a soil test to a certified lab to add the right balance fertilizers and lime materials to new gardens.

• Soil test salty parts of the field. Use the soluble salt number from a soil test to guide management decisions. • Improve surface and/or subsurface drainage in salt-affected fields. • Use more salt-tolerant cash crops, such as barley or wheat, instead of corn and soybean.

Soil Test 1: The Squeeze Test. One of the most basic characteristics of soil is its composition. In general, soils are classified as clay soils, sandy soils, or loamy soils.

Clay is nutrient-rich, but slow draining. Sand is quick draining but has trouble retaining nutrients and moisture. The recommendations in the tables are generated by equations and, therefore, change consistently across yield goals and soil test levels.

Due to space limitations, only the recommendations for selected yield goals and the mean soil test level of each soil test range (very low, low, medium, high, and very high) have been printed in this guide. When a group of producers were asked if soil testing would help improve crop yields, 82 percent responded positively.

But when the same group was asked if they used soil test routinely; only 28 percent replied “yes” (Kinsey, ). There are different approaches soil testing labs (com-mercial and public) and consultants may use when making.

To make best-management decisions for maintaining soil fertility, it is important to understand the basics of soil testing and reporting, whether you use a public or a commercial soil testing laboratory.

Bat guano is a fast-acting, organic fertilizer high in nitrogen and phosphorus, which promotes strong and healthy plant growth. It can also improve the texture of soil, improve drainage in heavy soils, and help to neutralize soil contaminants.

By increasing beneficial bacteria in the soil, it helps to protect plants against disease.
