“…A study in Montana showed that forbs did not respond to fertilizer treatments when seeded with more competitive grass species (Depuit and Coenenberg 1979). Russell et al (1965) found that N application decreased the percentage of legumes found in hay meadows in Nebraska. They also reported that P increased legume composition.…”

A revegetation technique study was established in a disturbed sagebrush-juniper community in northwestern Colorado in the fall of 1976. The purpose of the study was to identify effective cultural practices for establishing diverse and productive plant communities on disturbed soils. A combination of 4 treatments was applied:(1) altering life form seeding ratios, (2) seeding mixtures, (3) fertilizer, and (4) irrigation. After 4 years there was no significant difference in aboveground biomass production and canopy cover between irrigated and nonirrigated treatments. Fertilization increased production of grasses and shrub growth but depressed forb growth somewhat. The aboveground production of native and introduced mixtures was similar following four growing seasons. In general, introduced grasses out-produced native grasses, introduced forbs produced more than native forbs, and native shrubs out-performed introduced shrubs. Altering ratios among life forms affected shrub biomass more than forb and grass production. The use of different seeding rates indicates that phmt community composition will change and may be a function of not only seeding rates hut also plant and environmental factors over time and space.

“…The N X P interaction was quite similar in all years. Generally dry matter production exhibited a positive, linear response to increasing levels ofN with additional P while there was a quadratic response without additional P. Nitrogen and P together often produced higher yields than either applied separately (McMurphy et al, 197 5;Rehm, 1984;Rehm et al, 1972Rehm et al, , 1976Russell et al, 1965;Taliaferro et al, 1975). Results from our study indicated that P was apparently limiting at the higher N rates.…”

“…Early hay harvest and/or overgrazing shifted botanical composition (Weaver, 1954). Fertilization also altered species composition (Russell et al, 1965). Nitrogen fertilization promoted the invasion of cool-season grasses into warm-season grass stands, particularly ifN was applied in early spring or at rates high enough for residual N to accumulate (Rehm et al, 1976).…”

Botanical composition of native hay meadows throughout the True Prairie bas shifted from predominantly native, warm-season grasses to introduced, cool-season species following mismanagement. To determine if a shift in CO!Jlposition back to warm-season grasses and subsequent increased seasonal production could be achieved, atrazine (2-Chloro-4-{ethylamino)-6-{isopropylamino)-s-triazine) herbicide in combination with N and P fertilizer was evaluated on an eastern Nebraska subirrigated meadow. The soil is classified as a Lawet Vlll"i\lllt fine sandy loam (fine-loamy, mixed (calcareous), mesic Fluvaquentic Haplaquoll). Five rates of N (0, 45, 90, 135, and 180 kg ha -•), two rates of P (0 and 34 kg ha -•), apd two rates of atrazine (0 and 2.2 kg ha-•) in factorial combination were arranged in a randomized complete block design. Atrazine and P were applied in late April to late May, and N was applied in early June in 1982 through 1984. A combination of 180 kg N ha-• and 34 kg P ha-• produced dry matter yields 95, 101, and 77% greater than untreated plots in 1982, 1983, and 1984, respectively. Atrazine altered botanical composition from predominantly cool-season grasses to predominantly warm-season grasses. Changes ·in species composition by weight indicated a twofold increase in warm-season yield. This shift in seasonal distribution of yield was accomplished without a reduction in total dry matter yield compared with plots recieving 180 kg N ha -• in combination with 34 kg P ha-1 • · Additional index
