Esra Nur Gül, Emine Polat, Engin Özgöz, Naif Geboloğlu
Hort. Sci. (Prague), 2025, 52(4):342-352 | DOI: 10.17221/143/2024-HORTSCI 
Soil compaction has negative impacts on plant productivity. Degradation of soil structure as a result of soil compaction can inhibit the development of plant roots and make it difficult for plants to take up water and nutrients. This can negatively affect plant growth and productivity. Compaction restricts plant root growth by increasing mechanical resistance, reducing oxygen uptake, and thus reducing crop yields as it inhibits plant development. In this study, the effects of soil compaction due to machinery traffic on the physical structure of soil, morphological characteristics and yield of spinach were investigated in Tokat, where vegetable...
