A cooler than average start to the growing season has added some uncertainty to post-plant nitrogen fertilization strategies for Ontario corn producers. Soil supply of nitrogen to the corn crop is likely lower than normal due to reduced N mineralization from both soil organic matter and manure, and the Maximum Economic Rate of Nitrogen (MERN) […]
Interpreting the available nutrients in a fertilizer analysis Whether you are using a commercial fertilizer, organic amendments like manure or compost, or fertilizer by-products from industrial sources, it’s critical to know the nutrient analysis of the product. Analyses for agricultural nutrient sources may come in several different ways: When using a nutrient fertilizer source that […]
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 […]
Nutrient deficiencies occur regularly in Ontario and can be the cause of substantial yield loss depending on the type, severity and timing. Their presence is particularly frustrating when soil test levels show adequate levels of fertility. The simple answer Nutrient deficiencies can appear in soils testing moderate or high in plant nutrients given the right […]
The soil fertility benefits of applying livestock manure are significant. But storage is key. Uncovered storage facilities result in manure with a high volume of water and low nutrient value being shipped to fields. Fortunately, changes to storage facilities can improve efficiency of nutrient transport. The simple answer By covering liquid manure storage and diverting […]

Summary: Background: Throughout the growing season, microbes within the soil break down organic nitrogen contained in soil organic matter and crop residues and release it as plant-available ammonium. This process is known as nitrogen mineralization. Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration. Excess moisture can slow mineralization or […]

Frequent rains and wet soils across the province have slowed or prevented field work. Soil compaction is likely to be an issue this year, especially for farmers trying to get manure spread ahead of spring planting. Fertilizer has been moving out to farms with storage. Retailers are full and ready to apply product once soil […]
A warmer than normal winter coupled with dry weather through February has led to surprisingly good field conditions in much of southern Ontario. While it looks like it could be an early spring, we know that the weather can change rapidly this time of year. Some are questioning whether it makes sense to take advantage […]
