Key nutrients for soybean production in Kansas

Soybeans, particularly high-yielding varieties, remove significant amounts of available soil nutrients per bushel of grain harvested. As the crop matures, adequate amounts are needed in each growth stage. Learn which nutrients are the most critical to soybean production in Kansas.

Planning your wheat fertility program: Start now by soil testing

Wheat producers in Kansas should consider soil testing to help in making accurate fertilizer decisions. Accurate decisions are especially important during years with low grain prices and tight budgets.

Fall soil testing of hayfields and pastures

Fall is an excellent time to perform soil testing of pastures and hayfields. Testing in the fall allows more time for any needed lime applications before the main growing season and allows flexibility for planning fertilizer applications.

Planning your wheat fertility program: Start now by soil testing

Wheat producers in Kansas should consider soil testing to help make accurate fertilizer decisions ahead of planting. After variable conditions and yield levels across the state, fertilizer needs may require adjustments based on soil test results. Now is the time to take soil samples to ensure there will be enough time to consider the test results when planning your fall fertilizer programs.

Soil fertility and wheat production: Profile nitrate levels and wheat yield

Failure to account for soil nitrogen wastes a valuable resource and can result in excess foliage, increased plant disease, inefficient use of soil water, and reduced yield. Soil sampling in fall for nitrate-N can have a significant impact on N recommendations for winter wheat in Kansas soils.

Causes of yellow wheat - Soil fertility factors

Wheat producers may start seeing some wheat fields turn yellow during this time of the year. The pattern may vary from field to field, sometimes as large areas, small patches, or streaks of yellowish wheat in some fields this spring. This article goes into detail about some of the main causes of yellow wheat related to soil fertility.

In-furrow fertilizers for wheat

Wheat is considered a highly responsive crop to band-applied fertilizers, particularly phosphorus. The application of phosphorus as a starter fertilizer can be an effective method for part or all the phosphorus needs. Wheat plants typically show a significant increase in fall tillers and better root development with the use of starter fertilizer.

Fall soil testing of hayfields and pastures

Knowing the soil nutrients is a requirement to establish an adequate soil fertility program for forages. Fall is a good time to evaluate the soil fertility status for forage production because it allows more time for any needed lime applications to have an effect before the main growing season begins.

K-State Soil Fertility Schools for North Central and Northwest Kansas

With fertilizer being one of the most expensive components of your cropping system, it is increasingly important for producers to manage their agricultural inputs properly. K-State Research and Extension has scheduled four regional soil fertility schools during January 2024. This article has registration details and program information.

Updated soil test interpretations and fertilizer recommendations for Kansas

The Agronomy Soil Fertility Working Group at K-State, led by soil fertility specialist Dorivar Ruiz Diaz, has released an updated version of the popular publication "Soil Test Interpretations and Fertilizer Recommendations in Kansas". This publication contains the most recent soil test interpretations for the major crops for the most commonly deficient plant nutrients in Kansas.

Causes of yellow wheat - Soil fertility factors

Wheat producers may start seeing some wheat fields turn yellow during this time of year. This yellow discoloration is sometimes related to nutrients and soil fertility. Poor root growth from a myriad of factors can also lead to yellow wheat. Check out this article to learn about soil fertility factors affecting wheat growth.

Identifying nutrient deficiency symptoms in soybeans

As the growing season for soybeans progresses, the plants may begin showing signs of chlorosis or other leaf discoloration in all or parts of the field. There may be many causes of this discoloration. Nutrient deficiencies are one possibility. This article will briefly discuss various nutrient deficiencies and how to identify them in the field.

Liming soils for optimum wheat production

Strongly acidic soils may present several problems for wheat production. These include aluminum toxicity and, in some cases, manganese toxicity, as well as deficiencies in phosphorus, calcium, magnesium, and molybdenum. Where acid soils are reducing wheat production, liming the soils and raising the pH to an optimum range can significantly improve yield.

Allow time for lime applications when planting alfalfa this fall

Correcting acidic soil conditions by applying lime can significantly impact crop yields, especially for alfalfa. Acidic soils can significantly reduce nodule establishment and activity in alfalfa. Liming is one of the most essential but often overlooked management decisions a producer can make for alfalfa production.

Planning your wheat fertility program: Start now by soil testing

Now is a good time for soil sampling in preparation for wheat planting. This will help make the best fertility plan. This is particularly important after drought and lower-than-expected yields for previous crops. Fertilizer needs may require adjustments based on soil tests.

Soil fertility and wheat production: Profile nitrate levels and wheat yield

Does soil sampling in the fall for nitrate provide useful information for nitrogen fertilizer management in wheat production? This article addresses the correlation between the amount of nitrate in the soil profile and wheat yield.

In-furrow fertilizers for wheat production

Wheat is considered a highly responsive crop to band-applied fertilizers, particularly phosphorus. With the use of starter fertilizer, wheat typically shows a significant increase in fall tillers and better root development. Winterkill can also be reduced using starter fertilizers, particularly in soils that test low for phosphorus.

Fall soil testing of hayfields and pastures

Knowing the soil nutrients is required to establish an adequate soil fertility program for pastures and hayfields. Fall is a good time for soil testing because it allows more time for needed lime applications before spring and gives the producer some flexibility for planning nutrient applications.

Fall fertilization of smooth brome and tall fescue

Cool-season forages require annual fertilization for optimum production. Fall is a good time to plan on fertilizing cool-season improved pasture perennial grasses such as smooth brome and tall fescue. Fertilizer should be applied by broadcasting in the fall or before spring growth begins.

Considerations for fall applications of anhydrous ammonia

Some producers like the idea of applying anhydrous ammonia in the fall ahead of the following corn crop. However, several factors must be considered, including soil texture, temperature, and moisture. Currently, soil temperatures across Kansas are still above the recommended threshold when applying anhydrous ammonia.
