Sampling Dairy Manure and Compost for Nutrient Analysis

This guide describes how to obtain a representative sample of stockpiled dairy manure or dairy compost, select a reliable manure or compost testing laboratory, determine which lab analyses are needed (including total nitrogen, nitrate nitrogen, ammonium nitrogen, total phosphorus, total potassium and solids), and estimate nutrient availability. It gives illustrated, step-by-step sampling instructions and equations for converting units from dry weight to as received and vice-versa.

Calculating Dairy Manure Nutrient Application Rates

This publication describes how to calibrate waste-handling equipment and calculate nutrient application rates. It covers calibration of typical equipment found on dairies, such as stationary guns, traveling guns, liquid wagons, and solids spreaders. It uses nitrogen in the calibration examples, but the same techniques can be used with phosphorus.

Estimating Plant-Available Nitrogen from Manure

This publication discusses management practices that increase crop nitrogen utilization. It also includes an interactive worksheet for calculating available nutrients supplied by manure application. The worksheet can be used to determine the manure application rate needed to supply a target amount of PAN; estimate the dollar value of PAN from manure application; assess the balance between PAN, P, and K supplied by manure; and evaluate management options to increase crop N utilization.

Phosphorus on the farm from feed grains and by-products

Phosphorus is an important plant nutrient for growing dairy forages. Unfortunately, many dairies have more phosphorus excreted and stored in manure than they can use during a crop year. Soils have the ability to store moderate over-applications of phosphorus for future crop production, but continued over-application can lead to losses of phosphorus to surface water.
