Nitrogen Test For Manure
"This new tester allows you to quickly and accurately test livestock and poultry manure for plant-available nitrogen content without having to send samples far away for testing," says the Swedish manufacturer of the new Agros nitrogen meter.
Testing manure is important because plant-available nitrogen can vary from 0 to 40 kg of nitrogen per cubic meter, a spokesman points out. Measures all types of livestock or poultry manure in a matter of minutes. Sells for about $400.
