Mechanical decompaction and its relation to soybean yield in u

Compaction is one of the main soil physical limitations that negatively affects soybean production in Paraguay. The effect of mechanical decompaction in an Oxisol on soybean (Glycine max L.) production was evaluated. The experimental design used was a randomized block design, with 2 treatments with 10 replicates for each treatment: T1: without decompaction; T2: with mechanical decompaction. For the statistical analysis, each variable was subjected to Student's t-test for paired samples, grouped by depth and for independent samples. The variables evaluated were: soil penetrability at a depth of 60 cm by taking partial samples every 2.5 cm depth, soil bulk density up to a depth of 60 cm by taking samples every 15 cm, plant height, number of pods per plant, weight of 1000.
