Marion Calmer goes through his 40-year journey of replicated studies on nitrogen rates, row spacings, populations, tillage vs. no-till vs strip-till, residue management and most recently the long-term effects of surface-applied phosphorus and potassium.
A few frequent questions about phosphorus (P) fertilizer use are: Does P fertilizer always result in a positive yield response? How much yield increase is expected with applied P? What is the likelihood of yield penalty if P fertilizer is not applied?
Phosphorus, potassium, sulfur and nitrogen. All are traditional nutrients growers plan to put into soil each year to help maximize their yield potential. But did you know there are 3 other major components that are often overlooked?
It is becoming increasingly evident that we endanger our capacity to feed the world by over-assigning feed crops to prime farmland. The priority for this heritage is to grow crops for human edible food, while maintaining or improving soil health and overall ecological integrity.
Ensuring that your crops are rich in nutrients like Nitrogen (N), Phosphorus (P) and Potassium (K) is a crucial aspect of a healthy farm. But oftentimes, most of the N, P and K applied to the soil is never absorbed by the crop and does not have a chance to improve crop performance.
Many farmers are well-versed in the 4Rs of nutrient stewardship: apply the right source at the right rate, at the right time, in the right place. Following this framework ensures crops use nutrients efficiently and effectively, helping no-tillers maximize their fertilizer budget.
Cover crops reduce sediment loss and total phosphorus loss from no-till corn and soybean fields, according to a study published in the Journal of Environmental Management.
