Control traffic and traffic timing
A randomized, replicated experiment in 2008 on silty soils in Lublin, Poland (Siczek & Frąc 2012) found fewer bacteria (1,700 million colonies/kg) and lower bacterial activity in strongly compacted soil, but higher numbers and activity in moderately compacted soil (4,650 million colonies/kg) compared to an uncompacted treatment (2,600 million colonies/kg). Bulk density was 22.5% and 15.5% higher in the strongly and moderately compacted soil respectively, compared to uncompacted soil (1.3 Mg/m3). There were three compaction treatments in a soybean Glycine max crop obtained using a wheel tractor: strongly (5 passes), moderately (3 passes) and uncompacted (0 passes) soil. There were six replicates, total area for each compaction was not specified. Within each treatment were 1.8 x 2.1 m plots with no mulch, or mulched with straw. Fertilizer was applied uniformly to all plots at 54-70-80 kg/ha NPK. Soil was sampled three times during crop development from the centre of the soybean rows. Microbial parameters including bacterial number and enzyme activities were measured.

Add mulch to crops
A randomized, replicated experiment in 2008 on silty soils in Lublin, Poland (Siczek & Frąc 2012) found that adding a straw mulch increased bacteria counts (3.5 billion colonies/kg) and activity compared to soil with no mulch (2.4 billion colonies/kg). There were three compaction treatments in a soybean Glycine max crop obtained using a wheel tractor: strongly compacted (5 passes); moderately compacted (3 passes); and uncompacted (0 passes) soil. There were six replicates. Within each treatment were 1.8 x 2.1 m plots with either no mulch or a straw mulch. Fertilizer was applied uniformly to all plots at 54-70-80 kg/ha NPK. Bacterial numbers and enzyme activities were measured in soil samples taken three times during crop development from the centre of the soybean rows.
