Nitrate-N and Manure Nitrogen Index NH4-N, whether applied directly or from the mineralization of organic-N, is further converted to nitrate-N (NO3-N) by microbial action in the soil. This process occurs rapidly (weeks) during the growing season. Unlike NH4-N, which will adhere to soil particles, the nitrate ion can move freely with soil water. Loss of […]
Regular manure applications combined with forage-based rotations are the envy of crop producers when soil organic matter (SOM) levels and soil resilience are considered. What is the actual organic matter benefit from manure to the soil, and how does that vary with different types of manure and organic amendments? Livestock manure is an excellent source […]
Livestock manure is an excellent source of nutrients that can complement commercial fertilizer applications to produce high yielding, high quality crops. Studies have demonstrated improved yield and economic returns from the use of manure in cropping systems. The simple answer The short answer is yes. Manure (of any type) is found in most regions of […]
The Ontario manure nutrient calculator tool can be accessed by clicking the icon below. (this is the same tool previously posted on gocorn.net) Simple Summary Ontario Manure Nutrient Calculator What is the nutrient value of the manure I plan to apply? How does time of year or timing of incorporation impact my manure nitrogen credit? […]
It is difficult to manage what you don’t know. Sampling manure will provide information to help determine nutrient availability and determine where commercial fertilizer may or may not still be required. The link gives greater details about sampling and interpreting the results from manure samples. […]
Corn is the perfect crop for receiving the nutrients from manure. Liquid manure applied to meet two-thirds of the nitrogen needs will generally provide a good balance of the macro and micro nutrients needed for a highly productive corn crop. Using commercial starter and nitrogen for the balance of the crop’s needs ensures nutrients […]
Christine Brown, Sustainability Specialist – Field Crops, OMAFRA “A radical new way of thinking about soil has partially solved the mystery of why adding manure improves resilience, climate control, and crop yields.” – Dr. Andy Neal, Rothamsted Research. Have you ever wondered why forests can establish and thrive without being fertilized? Or, why grasslands, pastures, […]
Harvested wheat fields offer the perfect opportunity to focus on improving soil health. Planting cover crops and/or applying manure or other organic amendments provides soil microbes with the carbon compounds that help create a more porous soil structure which improves water, air and nutrient cycling. Here are a few common questions that come up every […]
The Ontario Virtual Crop Diagnostic Event will replace all in-person provincial crop diagnostic days that have been postponed this season due to the COVID-19 pandemic. The first series of diagnostic learning sessions begins on Wednesday July 15, 2020. For more information and to register go to OMAFRA Virtual Diagnostic Days Series website. While the management […]
Weather: Warmer conditions starting late last week have fast-tracked crop growth. Tracking growing degree day (GDD) accumulation – Base 0 – for April and May in Huron county revealed 159 GGD in April and 244 GDD from May 1-25. Rainfall during the past week was sporadic with isolated thunderstorms resulting in flooded fields in […]
With some out of the box thinking, Ken Hartemink, hog and cash crop producer from St. Thomas, Ontario has mounted a strip tiller to the back of his manure tanker for one-pass manure incorporation and seedbed prep for next year’s corn crop. Ken Hartemink is a hog and cash crop producer just outside St. […]
Introducing….to your mobile device or computer, the first of several on-line AgriSuite calculators that will help with agronomic and environmental land use decisions. The nutrient management software (commonly known as AgriSuite, which includes NMAN and MSTOR) has been available to Ontario Farmers for many years. Although popular, it is perceived to be mainly a regulatory […]
In much of Europe there have been restrictions to applying manure only during the growing season. There the technology has been perfected over time to meet those needs. Wouldn’t it be fitting to bring the technology to Ontario without the same application restrictions? I asked a few custom applicators what was holding them back from […]
Did you know that OMAFRA has a handbook that’s all about nutrients and soil fertility? It’s called the Soil Fertility Handbook and was first published in 1998. The book covers topics such as soil testing, soil pH and lime and fertilizer application. There’s a chapter on organic nutrient sources, like manure, biosolids and cover crops, […]
IFAO held a Compaction Action Day in September 2017 at Shawridge Farms at Arthur, Ontario. That event, attended by around 400 people, 16 equipment sponsors and 50 total sponsors, showcased a wide range of equipment and achieved a number of important things: It showed that a lot of people are concerned about compaction It raised […]
