Poultry litter should serve as an excellent complement to commercial nitrogen (N) fertilizers. Phosphorus (P) content in poultry litter is usually high, and applications rates should be based on P levels to avoid potential surface water contamination.

Check soil pH, phosphorus and potassium levels, organic matter, cation exchange capacity and base saturation on soil test analysis, says AgSource Laboratories.

University of Minnesota Extension shares what to consider when applying starter fertilizer for corn, and whether it's worth using when corn prices are low.

With soil pores continuously filled with water this time of year, Penn State Extension says applying manure increases the risk of runoff.

If wheat is yellow it's important to determine the cause, Kansas State University says, as growers can take action in some situations and correct the problem.

Iowa State University shares when starter fertilizer is likely to provide a benefit and the different application methods to consider.

Iowa State University estimates the economic cost of lost organic matter due to soil erosion and how it affects the long-term productivity of the soil.

With the first cutting of alfalfa nearing, the University of Arkansas Extension recommends no-tillers apply nutrients soon, especially phosphorus and potassium.

The Nutra-K line consists of five specialized potassium products with low-salt formulations that boost potassium and sulfur levels for maximum yield and crop quality.

Asgrow/Dekalb technical agronomist Lance Tarochione says soybeans remove a lot more nutrients than no-tillers realize, and meeting their fertility needs is key to higher yields.
