Nutrient Management

The educational materials listed on this page are about Nutrient Management.

A nutrient management plan is used to manage the application of plant nutrients and soil amendments. Integrated nutrient management may include utilizing variable rate application, soil inoculants, microbial inoculants, biologicals, foliar feeding and proper fertigation techniques and fertigation systems. An understanding of nutrient cycling can also aid in budgeting and supplying nutrients for plant production, while minimizing soil and water pollution. Farmers can harness the power of the nitrogen cycle by using organic fertilizer and manure to supply plant nutrients. Careful nutrient management can also improve the overall condition of soil, especially if your plan includes cover crops. Key practices include biological inoculantsnutrient cyclingfertigationorganic fertilizersreduced applicationsfoliar feedingmunicipal wastescover crops.

Building Soils for Better Crops, a book offered by SARE, helps farmers navigate ecological soil management strategies. A useful bulletin, Smart Water Use on your Farm or Ranch, addresses the role of water in a farm system and in nutrient management. The Season Extension: Fertility Management Topic Room helps producers gain knowledge of effective and proper fertility management techniques, including fertigation, to improve nutrient cycling on a farm. What is Sustainable Agriculture? provides information on best practices the encourage the stewardship of land, water and air resources.

Building Soils in Alaska Communities

Many Alaska communities have stated an interest in food production but perceive that a lack of adequate soils inhibits gardening. Most Alaskan producers confront related soil problems, such as thin root zones, nutrient-poor soils with low organic material contents, and some issues with permafrost. Despite the high cost of shipping, some producers actually import all of their garden soils from the continental United States on a barge, unaware that many of the necessary soil components can be found locally. This video demonstrates soil building and raised bed construction.
