Cattle manure is a valuable resource for farmers, as it contains an abundance of macro and micronutrients that are essential for plant growth and development. The nutrients present in manure, such as nitrogen (N), phosphorus (P), potassium (K), and other minerals are essential for soil fertility. One of the most significant advantages of using cattle manure as a fertilizer is that it can enhance the soil organic matter (SOM) content. Soil organic matter plays a crucial role in improving soil structure, water-holding capacity, and nutrient availability. Moreover, cattle manure can also increase the changeable fractions of carbon (C) & nitrogen (N) and enhance soil microbial activity, which is crucial for the decomposition and stabilization of soil organic carbon (SOC). The Knorr Holden plot, located at the Panhandle Research, Extension, and Education Center, Scottsbluff, Nebraska presents a unique opportunity for studying the impact of long-term manure (more than 77 years) applications on soil health and crop productivity.

With the two consecutive dry seasons in 2021 and 2022, there is likely a considerable amount of unused nitrogen left in the soil, which could be used for the 2023 crop. With the higher fertilizer prices, such fertility adjustments for next crop can be profitable as well as environment friendly. So, it is recommended to test your soil and account for all sources of nutrients for the next crop.

With the recent increase in fertilizer prices, it is more important than ever to use the right amount of fertilizer to maximize the economic returns. Applying too little or too much fertilizer can result in substantial economic loss.

Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?

In sugar beet production, most farmers do not have an option of manure as an alternative N source since N availability from manure can occur too late in the season and affect sugar quality. Composted cattle manure as different as it is from fresh manure might be a viable alternative N source for sugar beet production.
