Agronomic Evaluation of Separated Manure Solids Applied as Fertilizers and Soil Amendments under Manitoba Conditions

Project: MLMMI 2014-06


The overall objective of this project is to determine the agronomic value of separated swine manure solids as a replacement or complement for synthetic fertilizer. The specific objectives are as follows:

  1. To measure the crop yield, crop nutrient uptake and soil test response to N and P release from the separated manure solids applied under field conditions at a rate equivalent to 5 years of crop P removal. Analysis for plant nutrients in the crop and soil will be used to determine plant nutrient uptake efficiency and will also help to understand whether the non-N&P benefits associated with the separated manure solids (eg. K, S, micronutrients, plus biological and physical effects) have a direct effect on crop yield.
  2. To measure the concentrations of Cu and Zn in plants and soils where the separated manure solids have been applied.
  3. To examine the impacts of the separated manure solids on other soil quality parameters such as electrical conductivity.

Note to Reader concerning Phosphorous Redistribution Projects

In order to comply with current provincial manure management regulations, livestock producers in phosphorus surplus areas of Manitoba have to implement ways to redistribute nutrients to phosphorus deficient areas. The Manitoba Livestock Manure Management Initiative (MLMMI) is undertaking a series of projects to find effective affordable solutions for producers. This report is one of these projects.

All options available to producers in phosphorus surplus areas are under consideration. These include but are not limited to manure separation, manure handling and storage, and liquid manure transportation. This report is only one of many options that are under consideration.
