“…No differences in Fe concentrations were found among the six grasses, but Coastal bermudagrass, indiangrass, and switchgrass showed differences in Fe concentrations between years (Table 10). Tissue Fe concentrations were within the range of those reported for Coastal bermudagrass (average of 92 mg kg −1 ) fertilized with swine effluent (Burns et al, 1990) but below those reported (166–260 mg kg −1 ) for turf bermudagrass cultivars (McCrimmon, 2000, 2002).…”

“…Forage Mn concentrations (Table 11) were below the range of those reported for Coastal bermudagrass (25–325 mg kg −1 ) (Mills and Jones, 1996) and turf cultivars (McCrimmon, 2000, 2002). Uptake of Mn was greater in bermudagrass than in johnsongrass in all 3 yr.…”

“…Forage Zn concentrations (Table 12) were less than the average of 33 mg kg −1 reported by Burns et al (1990) for Coastal bermudagrass fertilized with swine effluent and also below those reported for heavily fertilized turf bermudagrass cultivars, which averaged 72 to 93 mg kg −1 (McCrimmon, 2000, 2002). Zinc concentrations in harvested forage in the present study increased from 2000 to 2002 in all grasses except indiangrass and appeared to be independent of yearly variations in effluent application.…”

“…Tissue Cu concentrations (Table 9) were lower than the average of 9 mg kg −1 reported by Burns et al (1990) for Coastal bermudagrass fertilized with swine effluent, possibly due to differences in seasonal effluent loading rates. Studies of micronutrient uptake in 15 clipped turf bermudagrass cultivars under irrigation and monthly N and K fertilization (196 kg ha −1 yr −1 of N and K) showed Cu concentrations averaging 13.5 to 14.8 mg kg −1 (McCrimmon, 2000, 2002). Increased fertilizer N and K (343 kg ha −1 yr −1 of N and K) resulted in a higher average Cu concentration of 22.0 mg kg −1 in the turf bermudagrass cultivars (McCrimmon, 2002).…”

Haying removes soil nutrients in manured fields. Grass hays were compared for nutrient removal in an effluent spray field. Eastern gamagrass (Tripsacum dactyloides L.), indiangrass [Sorghastrum nutans (L.) Nash], johnsongrass [Sorghum halepense (L.) Pers.], switchgrass (Panicum virgatum L.), and common and ‘Coastal’ bermudagrass [Cynodon dactylon (L.) Pers.] were grown on a Brooksville silty clay (fine, montmorillonitic, thermic Aquic Chromuderts) in Mississippi. The field produced johnsongrass hay and received swine (Sus scrofa domesticus) effluent (estimated 371, 61, and 629 kg ha−1 yr−1 of N, P, and K, respectively) for 8 yr before the study. In the 3‐yr study, common bermudagrass produced 4.6 to 15.0 Mg dry matter (DM) ha−1 yr−1 and was not different from Coastal bermudagrass (5.2 to 13.7 Mg ha−1 yr−1). Highest annual DM yields of johnsongrass, eastern gamagrass, switchgrass, and indiangrass were 9.7, 9.5, 9.1, and 5.5 Mg ha−1 yr−1, respectively. Highest annual uptakes of N by common and Coastal bermudagrass, johnsongrass, eastern gamagrass, switchgrass, and indiangrass were 314, 280, 188, 181, 167, and 106 kg ha−1, respectively. Respective highest annual uptakes of P were 44, 35, 23, 21, 19, and 14 kg ha−1. Uptakes of Ca, K, Mg, Cu, Fe, Mn, and Zn were as high or higher in common bermudagrass as in the other grasses. Dry matter yield of common bermudagrass was correlated (r = 0.99, P = 0.0001) with uptakes of N, P, and K. Replacing johnsongrass with bermudagrass would increase annual DM yield in the field 155 to 249% and P uptake 194 to 259%.

“…Jones (1980) suggested sufficiency ranges for grasses in the USA, although they were relatively broad. For instance, the optimum concentration for N was from 2.8 to 3.5%, from 0.30 to 0.55% for P, and from 1.0 to 2.5% for K. McCrimmon (1998) studied the mineral composition of 15 bermudgrasses in Louisiana with low and high N and K applications. Nutrient concentrations varied with the cultivar, although the differences were generally small, with high nutrient applications not necessarily increasing shoot N or K. Under high N and K supply, shoot nutrient concentrations were as follows: N, 3.9-4.6%; P, 0.32-0.41%; K, 1.9-2.7%; S, 0.32-0.49%; Ca, 0.42-0.62%; and Mg, 0.14-0.21%.…”

The effects of fertilisers on 8 tropical turfgrasses growing in 100-L bags of sand were studied over winter in Murrumba Downs, just north of Brisbane in southern Queensland (latitude 27.4°S, longitude 153.1°E). The species used were: Axonopus compressus (broad-leaf carpetgrass), Cynodon dactylon (bermudagrass ‘Winter Green’) and C. dactylon × C. transvaalensis hybrid (‘Tifgreen’), Digitaria didactyla (Queensland blue couch), Paspalum notatum (bahiagrass ‘38824’), Stenotaphrum secundatum (buffalograss ‘Palmetto’), Eremochloa ophiuroides (centipedegrass ‘Centec’) and Zoysia japonica (zoysiagrass ‘ZT-11’). Control plots were fertilised with complete fertilisers every month from May to September (72 kg N/ha, 31 kg P/ha, 84 kg K/ha, 48 kg S/ha, 30 kg Ca/ha and 7.2 kg Mg/ha), and unfertilised plots received no fertiliser. Carpetgrass and standard bermudagrass were the most sensitive species to nutrient supply, with lower shoot dry weights in the unfertilised plots (shoots mowed to thatch level) compared with the fertilised plots in June. There were lower shoot dry weights in the unfertilised plots in July for all species, except for buffalograss, centipedegrass and zoysiagrass, and lower shoot dry weights in the unfertilised plots in August for all species, except for centipedegrass. At the end of the experiment in September, unfertilised plots were 11% of the shoot dry weights of fertilised plots, with all species affected. Mean shoot nitrogen concentrations fell from 3.2 to 1.7% in the unfertilised plots from May to August, below the sufficiency range for turfgrasses (2.8–3.5%). There were also declines in P (0.45–0.36%), K (2.4–1.5%), S (0.35–0.25%), Mg (0.24–0.18%) and B (9–6 mg/kg), which were all in the sufficiency range. The shoots in the control plots took up the following levels (kg/ha.month) of nutrients: N, 10.0–27.0; P, 1.6–4.0; K, 8.2–19.8; S, 1.0–4.2; Ca, 1.1–3.3; and Mg, 0.8–2.2, compared with applications (kg/ha.month) of: N, 72; P, 31; K, 84; S, 48; Ca, 30; and Mg, 7.2, indicating a recovery of 14–38% for N, 5–13% for P, 10–24% for K, 2–9% for S, 4–11% for Ca and 11–30% for Mg. These results suggest that buffalograss, centipedegrass and zoysiagrass are less sensitive to low nutrient supply than carpetgrass, bermudagrass, blue couch and bahiagrass. Data on nutrient uptake showed that the less sensitive species required only half or less of the nitrogen required to maintain the growth of the other grasses, indicating potential savings for turf managers in fertiliser costs and the environment in terms of nutrients entering waterways.
