From Ian McDonald, OMAFRA, Field Crops Unit:
Where NutrientSmart and FarmSmart in January dealt with the theory of soil management and nutrient use and management of inorganic nutrient sources, NutrientSmart 2.0 will explore the integration of organic amendments such as manures, biosolids, compost, green bin compost, and other sources into a systems approach to nutrient management planning for production in relation to soils. It will explore for both crop and livestock farmers and advisors how to source, apply, match and gain economic and environmental advantage from the use of these important and valuable sources of nutrients.

Micronutrients play an essential role in vegetable crop production. However, planning a fertilizer strategy involving micronutrients can be difficult. Micronutrient fertilizers are often expensive and, depending on the element, the actual return on your investment is not always obvious. The fear of a shortfall often outweighs the actual potential for deficiencies.

By Christoph Kessel, Nutrition (Horticulture) – Program Lead, OMAFRA
Crops require boron, copper, iron, manganese, molybdenum or zinc in relatively small amounts. If your soil test report recommends the application of one of these micronutrients, there are several organic and inorganic sources from which to choose.
Soil organic matter and organic sources such as composts and manures are an often overlooked micronutrient storehouse. For example a one ton manure application can provide (in lbs) 0.02-0.1 boron, 0.04-06 copper, 0.4-2 iron, 0.2-1.0 manganese, 0.0002-0.01 molybdenum, and 0.2-1 zinc. Micronutrient content depends on the source but an added benefit is that they are generally already in the plant available forms. With planning and careful management, organic sources can provide a long term sustainable micronutrient source to plants.
