“…Note that potential error is possible in the determination of crop N uptake as below-ground N content and biomass were estimated from above-ground values. However, both N content and biomass estimates from above-ground measurements are reasonably accurate as were based from previous studies (Ashraf and Yasmin, 1991;Heckathorn and DeLucia, 1994;Levang-Brilz and Biondini, 2002;Mahaney et al, 2008;Mata-González et al, 2002;Schimel et al, 1985;Wilsey and Polley, 2006). Looking at the treatments in Table 4, gaseous N losses were 50, 64, and 61% of the N applied by the CW 313, CW 471, and CW 627 kg N ha −1 treatments, respectively.…”

“…Root biomass and N were estimated by using shoot-root biomass and N ratios of 0.8 and 1.0. The ratios were determined from past research on Cynodon dactylon (Ashraf and Yasmin, 1991) and other C 4 or warm-season grasses under similar N, soil moisture, and environmental conditions (Heckathorn and DeLucia, 1994;Levang-Brilz and Biondini, 2002;Mahaney et al, 2008;Mata-González et al, 2002;Schimel et al, 1985;Wilsey and Polley, 2006). Plant tissue analysis was performed by the standard methods described by Westermann (1990).…”

“…This species presents a root/shoot ratio of 1.13 to 1.90, at least in the first stages of growth (42) . Other studies report for developed grasses a root/ shoot ratio of 3 in B. gracilis and 2.5 in Hilaria mutica (45) , 4.3 in Sorghastrum nutans and 4.9 in Bouteloua curtipendula (46) and 5.5 in especie, no se encontraron diferencias entre la germinación de semilla expuesta y no expuesta al fuego (42) . En ambos casos, las semillas germinan lentamente, lo que le da ventajas competitivas en lugares con lluvias escasas e irregulares como en zonas áridas (43) .…”

RESUMEN El pasto rosado (Melinis repens) es una especie introducida de África que invade diversos ecosistemas. EnMéxico se encuentra en todos los Estados, y en Chihuahua es la especie dominante en extensas áreas de pastizales. Las invasiones reducen la calidad y cantidad de los productos y servicios del ecosistema. No se sabe exactamente cuándo llegó al continente americano. Dependiendo de las condiciones climáticas puede comportarse como anual o perenne de vida corta. Produce abundante semilla durante años con precipitaciones por debajo de lo normal comparados con años lluviosos. La germinación de la semilla puede ser en presencia de luz o sin ella, la máxima germinación es entre 20 a 35 ºC; a -0.2 MPa se inhibe la germinación y el fuego no la afecta. ABSTRACTNatal grass (Melinis repens) is an introduced specie from Africa that is invading different ecosystems. In Mexico, it is present all over the country and dominates large areas of grasslands. Plant invasion reduces quality and quantity of ecosystem goods and services. The knowledge of the biology of invasive species is a key factor when a management and control plan will be established. It is unknown when this specie arrived to America. Depending on climatic conditions this grass may behave as annual or perennial. Seed production is larger in years with precipitation below normal than in wet years. Germination takes place with or without light, optimum temperature is from 20 to 35 ºC; at -0.2 MPa germination is inhibited, and fire does not affect seed germination. When moisture is not limited and during the early development, root:shoot ratios ranges from 1.13 to 1.90 and relative growth rate from 0.0034 to 0.15 mg g-1 d-1 ; also, biomass is reduced when natal grass grows on native soil compared to sterilized soil. Although it is considered as poor forage, the main use is as pasture. Other uses reported include ornamental, medicinal, and fito-remediation. Fire favors its growth, and no control method is known. So far, grazing of natal grass is the most viable management. Additionally, when planning a control campaign it is important to reduce the movement of this specie as part of human activities.

“…Mata-González, Sosebee, and Wan (2002) reported that shoot biomass of B. gracilis is affected by the interaction of level and season of biosolid application. The use of biosolid nitrogen (N) for plant growth depended on the time in which the decomposition took place and released N as well as on sufficient soil moisture availability (Mata-González, Sosebee, and Wan 2004).…”

An experiment was conducted in three wild grass species of Bouteloua genus to compare the effect of application of biosolids on the accumulation of heavy metals, biomass production, and nutrient uptake. Biosolids were applied at rates of 0, 3.5, 7, and 10.5 Mg ha −1 to two different soil types collected from the southern Chihuahuan Desert. The shoot biomass of B. gracilis (BOGR) and B. scorpioides (BOSC) was two to three times greater than the control while in B. curtipendula (BOCU) in was 75% in both soils. In BOGR, nitrogen and phosphorus uptake were 4-4.5 times greater than the control in calcareous soil. With few exceptions, there was no significant difference of heavy-metal concentrations (copper, chromium, arsenic, nickel, and zinc) in the plant tissues compared to the control. The application of biosolids showed interspecies variability in growth response and nutrient uptake with a minimal risk of heavy-metal uptake for Bouteloua wild species.
