草地青贮管理一般是临时的，导致土壤压实破坏。文献表明，通过压实，草产量减少5%至74%（英国平均值为13%），而2015年的一项研究报告，比较了控制交通农业（CTF）和正常管理（N）之间的草干物质（DM）产量，发现CTF增加了13.5%（0.80 t ha−1）。为CTF设置的宽度为3至12米的市售牧草饲料设备将N的运输面积从80%-90%减少到40%-13%。经济分析的基础上增加13%的DM为2和3切割系统，得到了£38和£98 ha−1之间的草价值增加。CTF用于多茬草青贮饲料，通过减少压实和草皮损害有效提高产量。
Grassland silage management is generally ad hoc resulting in soil compaction damage. Literature suggests grass yield reductions of 5 to 74% through compaction (UK mean 13%), while a 2015 study, reported here, comparing grass dry matter (DM) yield between controlled traffic farming (CTF) and normal management (N), found a 13.5% (0.80 t ha−1) increase for CTF. Commercially available grass forage equipment with widths of 3 to 12 m set up for CTF reduced trafficked areas from 80%–90% for N to 40%–13%. Economic analysis based on 13% increase in DM for 2 and 3 cut systems, gave an increased grass value between £38 ha−1 and £98 ha−1. CTF for multi-cut grass silage effectively increases yields by reducing compaction and sward damage.
