“…It is possible that pH changed locally in the rhizosphere and possibly only temporarily following N application. Soil P levels were deemed adequate based on soil test calibration studies for creeping bentgrass on sand root zones using the Bray 1 procedure (Guillard and Dest, 2003;S.M. Our most acidifying treatment, ammonium sulfate applied at 244 kg ha −1 yr −1 , was the only treatment to add more acidity (1282 CCE) than the irrigation water could counteract.…”

“…Nitrogen, P, and K were not likely to be limited within our soil pH range (for both root zones) of 7.0 to 7.9 (Carrow et al, 2001), however it is possible that VBG has a diff erent nutrient uptake response at alkaline pH levels than creeping bentgrass. Soil P levels were deemed adequate based on soil test calibration studies for creeping bentgrass on sand root zones using the Bray 1 procedure (Guillard and Dest, 2003;S.M.

Nitrogen Source and Rate Effects on Velvet Bentgrass Putting Green Turf

Nitrogen source and rate effects on velvet bentgrass (Agrostis canina L.; VBG) putting greens are not well documented, particularly in the north central United States which has different conditions than areas where VBG is normally grown. Acidic soil pH is perceived as necessary for VBG; in nonacidic soils, acidifying fertilizers may provide better VBG quality than less or nonacidic fertilizers. We wanted to determine the effects of N sources representing a range of acidity and N rates (49, 146, 244 kg ha−1 yr−1) on VBG agronomic and playability characteristics when grown on alkaline soils. Fertilizer treatments were applied at 2‐wk intervals to ‘Vesper’ VBG putting greens using liquid forms of ammonium sulfate, urea, ammonium nitrate, and calcium nitrate. Separate trials were conducted on two root zones: an 80:20 sand/peat mixture (pH 7.8) and a Troxel silt loam (pH 7.0). Nitrogen source usually had negligible effects on turf characteristics, though occasionally calcium nitrate resulted in poorer quality or shoot density than other sources. Clipping yield, shoot density, and relative chlorophyll index increased, and ball roll distances decreased, as N rate increased. On sand, not even the 244 kg ha−1 yr−1 rate of N guaranteed acceptable turf quality. On silt loam, 146 kg ha−1 N yr−1 usually provided acceptable turf quality, though quality was occasionally improved at 244 kg ha−1 N yr−1 Velvet bentgrass suffered from mid‐summer stress alleviated by higher rather than lower quantities of N fertilizer.

“…However, turfgrass is not typically fertilized to maximize yield. Therefore, other attributes such as visual turfgrass quality, shoot density, root mass, and tissue P content have been used to determine the STP critical point in turfgrass (Guillard and Dest, 2003;Johnson et al, 2003).…”

“…In a study that related turfgrass growth response to extractable soil P concentration in sand greens, Guillard and Dest (2003) reported that extractable P was highly correlated among Mehlich 1, Bray 1 and modified Morgan procedures with r value of around 0.9. Oladeji (2006) reported that the Mehlich 1, WEP, and Fe oxide P concentrations were closely related to each other with r values generally more than 0.7 for growth of bahiagrass overseeded with ryegrass in a glasshouse study.…”

St. Augustinegrass [Stenotaphrum secondatum (Walt.) Kuntze] is a home lawn grass widely used in the southern United States. At present, phosphorus (P) fertilization of St. Augustinegrass is based primarily on Mehlich 1 P test. One criticism of Mehlich 1 extractant is that it extracts some fraction of soil P pool that is not available to plants, whereas, iron (Fe) oxide P and water-extractable P methods are reported to be better related to plant growth in some cases. Literature relative to the soil test procedure comparison for St. Augustinegrass was not found. The objective of this study was to evaluate Mehlich 1 P, Fe oxide P, and water-extractable P to identify the most suitable soil test method for St. Augustinegrass growth. Established pots of 'Floratam' were subjected to P application of 0, 0.14, 0.27, 0.54, and 1.07 g m 22 every 4 wk for 12 wk. Measurements included tissue growth rates, tissue P concentration, soil Mehlich 1 P, Fe oxide P, and water-extractable P concentrations. Phosphorus application increased soil test P concentrations. Soil Mehlich 1 P, Fe oxide P, and water-extractable P concentrations were closely correlated to each other. Three soil test P levels and tissue P concentrations were highly correlated with Mehlich 1 P, which best predicted tissue P levels. Three soil test P levels were also closely correlated to the St. Augustinegrass top growth rate. Critical minimum Fe oxide 2234 P and water-extractable P concentration was 3 mg kg 21 . Overall, Mehlich 1 P was the best soil P test for St. Augustinegrass among the three extractants tested.
