Soil health is the cornerstone of balanced crop nutrition. Up to 60% of yield is dependent on soil fertility. Setting the foundation for healthy soils provides greater crop productivity and sustains the land for generations to come.
Each harvest comes with a degree of soil nutrient removal, depending on the crop and yield. Consider a fall fertilizer application to maintain nutrients in the soil after harvest and prepare fields for the 2021 growing season. Read on to learn how interpreting soil test results and strategic application timing can set you up for success next year.
The 4R program still is and will continue to be a very important program for the crop nutrition industry.
Risks associated with fall nitrogen (N) applications fit into four categories: logistical, agronomic, environmental and economic, the last of which currently ties very closely to the others and will be discussed in conjunction with them.
For Luke Lantz, a farmer from Lake Crystal, Minnesota, fall fertilization plans are not a one-size-fits-all program.
In his keynote address at the 11th International Conference on Precision Agriculture, Dr. Newell Kitchen, USDA-ARS, highlighted the significant role that nutrient management plays in the industry.
States and tribal agencies have had the responsibility in the USA to establish nutrient criteria for water quality protection, based on the Clean Water Act. According to the U.S. Environmental Protection Agency, over 10,000 nutrient and nutrient-related water quality impairments have been listed across 49 states. Some states and tribes have made progress in moving from “narrative” nutrient criteria to “numeric” criteria for protecting surface water resources, while others have faced more challenges.
One of the social requirements of farming today is to run a sustainable business. But that doesn’t mean science should fall by the wayside. Just the opposite, in fact.
Every January, millions of resolutions are made to eat healthier, get organized, or stop bad habits. But New Year’s resolutions can be made on the farm, too – especially when it comes to improving your soil fertility.
The principles of 4R Nutrient Stewardship require scientific support for the choice of practices that deliver the right source of nutrients at the right rate, time and place. The science needs to test these practices for their outcomes in terms of economic, social and environmental sustainability.
