Partial manure injection – a compromise solution to combat nitrogen loss

Testing shows that partial injection decreases ammonia nitrogen volatilization by one quarter to one third. But too much incorporation damages the alfalfa, so some ammonia loss will happen


Livestock farmers face a dilemma when making the best use of their liquid manure asset to fertilize crops. Expensive nitrogen is the most volatile of the three basic fertilizer elements.  It can also be a major pollutant, either as ammonia vaporized into the air or as nitrate leached into the soil and ending up in drinking water.
