Precipitation and heat are major limitations to the adaptation of tall fescue west of I-35. Tall fescue is a cool-season perennial forage that generally needs a minimum of 32-36 inches of annual rainfall for production and persistence.
By taking soil samples during the fallow period, soil nitrate nitrogen levels can be appraised with a great degree of confidence. Due to the instability of soil nitrogen, even the residual levels identified by soil test often change before plants utilize the applied or mineralized nitrogen.
I want to use this article to address commonly asked questions regarding the role of nitrogen, phosphorus and potassium in plants and outline the characteristics of their primary fertilizer sources.
Fertilizer, swathing, raking, baling and labor expenses can push the cost of haying bermudagrass up to $30/ton or more. With that kind of investment, it's important to implement proper management to assure a positive return.
This fact sheet talks about acidity's causes and corrections, the amount of lime needed to raise the pH, and the length of time liming takes to work.
Between 2003 and 2006, a project was conducted on the Noble Research Institute Headquarters Farm to demonstrate the possibility and practicality of pasturing stockers on bermudagrass while using legumes instead of nitrogen fertilizer.
Noble Research Institute researchers search for ways to develop crop plants that require fewer finite resources.
We often discuss bermudagrass as being a very "short season" forage plant but I did not realize how short it can be until I reviewed some yield data.
Under most situations, all the required nutrients, as recommended by a soil test, should be applied and incorporated into the soil prior to planting - the only exception is nitrogen.
In a time of record high fertilizer and commodity prices, should you apply sulfur (S) fertilizer? Well, an economist would say, "It depends." As an agronomist, I would have to agree with them. Some critical factors for applying S fertilizer are S soil test level, soil type, yield goal for the crop, amount of nitrogen fertilizer being applied and the amount of S obtained from rain, irrigation and other sources.
