The document discusses various steps involved in improving the utilization of manure nitrogen through making manure heaps, monitoring heap temperature, spreading manure on grassland, applying irrigation, estimating ammonia emission, comparing grass growth, harvesting and weighing cut grass, conducting field experiments, litter bag studies to estimate nitrogen uptake, collecting soil samples, inspecting fields, and measuring ammonia emission from manure through activities like trampling by animals.
