Designed to help dairy owners determine manure application rates and forage consumption. Describes how to: (1) estimate manure generated by animals and the confinement facility; (2) measure grass consumed by animals using clip and weigh, yardstick, rising plate meter, and capacitance meter methods; (3) determine nitrogen (N) content of grass; and (4) use these calculations to ...

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.

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.

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.
