Conservation Planning / Nutrient Management

As prices for land, water, inputs and equipment go up, good nutrient management on all fields becomes increasingly important.  Manure and wastewater contain valuable nutrients that, if managed properly, can help meet crop nutrient needs and increase soil quality and fertility.  The amount, timing, rate, and placement needs to be considered when manure or wastewater is applied.manurespreader_newholland_example

Regulation 81 stipulates that “No application of manure or wastewater shall be made to a land application site at a rate that will exceed the capacity of the soil and the planned crops to assimilate plant available nitrogen within 12 months of the manure or wastewater being applied.”  Lab testing of land application area soils, as well as manure and wastewater will reveal the amount of nutrients in each type of material.  Using this information in concert with the expected nutrient needs of the planned crop, agronomic balance calculation can be made and the application rate determined.

A well-prepared Nutrient Management Plan (NMP) describes how much manure and wastewater is generated at the facility, the land available for application, production area maps and soils information, types of crops and forage produced, nutrient balancing on fields receiving manure, wastewater or compost, and the record-keeping system that is used to ensure that nutrients, such as nitrogen and phosphorus, are not over-applied on fields. The plan will also include Nitrogen and Phosphorus Transport Risk Assessments for each field.

Annual maintenance of a Nutrient Management Plan includes doing the sampling and testing of land application field soils, manure, wastewater, irrigation water and compost (if applicable), and using this information to prepare agronomic balance sheets for all fields that will receive waste applications.  The nutrient management plan should be kept up to date and be available for examination by regulators, and records must be kept on site for a minimum of five years.cover crop and residue

When additional land is purchased or leased, or farming or irrigation practices change, the NMP should be updated to ensure regulatory compliance.  This also helps ensure that your fields are getting the maximum benefit from the soil amendments being applied.

Monitoring soil health in land application fields is crucial to maximizing crop production.  Part of our compliance management program includes tracking soil health parameters from year to year and meeting with customers periodically to go over land application field soil fertility conditions.  At Brink, Inc., we focus on helping our customers build and improve soil health in order to reduce the need for costly fertilizer and pesticide inputs.
