Pedotransfer Function

“Twenty-seven years of organic no-till in central Ohio, comparing compost, manure, cover crop and fallow treatments, produced measurable differences in soil physical quality — bulk density, penetration resistance, water-stable aggregates, saturated hydraulic conductivity, organic carbon and plant-available water — at two depths, combined into a single soil physical quality index. The dataset offers a rare long-term benchmark for how organic amendments and continuous cover shape soil structure and water-holding ability.”
