On-farm production of arbuscular mycorrhizal [AM] fungus inoculum can be employed to make the benefits of the symbiosis more available to vegetable farmers. Experiments were conducted to modify an existing method for the production of inoculum in temperate climates to make it more readily adoptable by farmers. Perlite, vermiculite, and peat based potting media were tested as diluents of yard cl...

Effects of applications of exceptional quality (low toxic minerals), high molybdenum (Mo)containing biosolids (sludge) to bahiagrass (Paspalum notatum) pastures in successive years, or residual effects of applications the previous year, on minerals, crude protein (CP) and in vitro organic matter digestibility (IVOMD) status of forages in north Florida were studied in relation to beef cattle nut...

Differences in nutrient content between different grass hay varieties are much smaller than differences between legumes and grasses (Table 1). Cool-season grasses (grown in temperate climates) include timothy, orchardgrass, fescue and annual ryegrass. Warm-season grasses (adapted to tropical and subtropical regions, like Florida) include Coastal bermudagrass, Tifton-85 bermudagrass, and bahiagr...

Novel approaches are needed for overcoming barriers to successful association of herbaceous legumes with grasses in warm-climate pastures and to identify low-cost, long-term solutions to the problem of N limitation in low-input systems. The objective of this experiment was to evaluate defoliation management options during the year of establishment when rhizoma peanut (rp) (Arachis glabrata Bent...

Fermentation in the rumen of cattle produces methane (CH4). Methane may play a role in global warming scenarios. The linking of grazing management strategies to more efficient beef production while reducing the CH4 emitted by beef cattle is important. The sulfur hexafluoride (SF6) tracer technique was used to determine the effects of best management practices (BMP) grazing compared with continu...

The efficacy of coastal bermudagrass (Cynodon dactylon) as a rotation crop for controt of root-knot nematode (Meloidogyne arenaria) in 'Florunner' peanut (Arachis hypogoea) was evaluated in a 3-year field trial. Coastal bermudagrass-peanut rotation (CBP) was compared with peanut monoculture without nematicide (P - ) and peanut monoculture with aldicarb (P + ). The performance of CBP was also co...

This trial was designed to compare both corn and citrus pulp with added UIP as potential supplements for growing cattle fed low quality bahiagrass hay. Citrus pulp supplements produced gains similar to corn and performance was enhanced as level of UIP increased. Maximum ADG was achieved at 0.48 lb of added UIP. It is unclear if 0.48 lb of added UIP is the optimal level of supplementation becaus...

Our objectives were to compare the effects of sources of supplemental N on ruminal fermentation of dried citrus pulp (DCP) and performance of growing steers fed DCP and bahiagrass (Paspalum notatum) hay. In Exp. 1, fermentation of DCP alone was compared with that of isonitrogenous mixtures of DCP and solvent soybean meal (SBM), expeller soybean meal (SoyPLUS; SP), or urea (UR). Ground (1 mm) su...
