Effects of a Control Release Nitrogen Fertilizer and Thinning on the Nitrogen Dynamics of a Mid-Rotation Loblolly Pine Stand in the Piedmont of Virginia
… treatments on N availability and loss as: total KCl extractable-N, total ion exchange membrane-N (IEM-N), N mineralization, and N volatilization, in a mid-rotation loblolly pine plantation in the Piedmont of Virginia. In addition, mid-summer and mid-winter fertilizations were compared to assess …

The amendment of acid soil with an ettringitic waste and its effects on plant growth
… amendments for two weeks, following which pH(KCl), pH(H20) and KCl-extractable acidity were determined. Ettringitic waste led to apparently lower levels of acidity neutralization for corresponding treatments set on an HCl-CCE basis. This difference was minimized with the highly buffered, …

Effects of soil amendments on crusting, seedling emergence and yield of onion, tomatoes and peppers.
… index, soil-pH, electrical conductivity, DPTA-extractable soil Fe, Cu, Zn, Mu and seedling emergence in two greenhouse experiments. Gypsum and H₂SO₄ increased seedling emergence while Al₂(SO₄)₃ reduced the soil-pH and EC more than H₂SO₄ and gypsum. Based upon penetrometer readings, H₂SO₄ was …

Impacts of Fertilization on Soil Properties in Loblolly Pine Plantations in the Southeastern United States
… soil types. In contrast, fertilization increased extractable P in soil CRIFF groups 1, 2, and 3 by 26, 60, and 4 kg P ha-1 respectively suggesting potential for long-term soil P availability and site quality improvement. However, the low extractable P in soil group 3 implies additional …

Plant Functional Traits and Ecosystem Functions in Experimental Grassland Stands
… at 15, 30 and 90 cm, seepage at 100 cm depth. KCl-extractable Nmin was determined in June and September. NH4, NO3, DON, DOC, K, Mg and Ca were measured in solution and nutrients in above- and belowground biomass. In Experimental Grassland Stands on lysimeter facilities, herb contribution to …
