ABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production. Typically, these grasslands have low herbage phosphorus (P) concentration, and P deficiency in livestock is not rare. Worldwide, P fertilization is used to increase the productivity and nutritive value of grasslands, but it is unknown whether the Río de la Plata grasslands are limited by P availability. -- Methods: We quantified the response of aboveground net primary productivity (ANPP) to P supply in a meta-analysis of 39 trials carried out between 1968 and 2016 comprising 285 independent comparisons (cases) between unfertilized controls and P-fertilized treatments. -- Results: The ANPP of unfertilized controls ranged from 400 to 17,500 kg dry matter (DM) ha-1 y-1. In 74% of cases, P fertilization did not increase ANPP. The average response was therefore low, at 399 kg DM ha-1 (relative effect + 15%), and largely unrelated to ANPP, vegetation, or soil characteristics. Conversely, in 59% of cases herbage P concentration did increase, particularly at high fertilization rates (average 0.43 mg P g DM-1; relative effect + 36%). -- Conclusions: Despite low herbage P concentration, the current ANPP of Río de la Plata grasslands seems little limited by P supply. Luxury consumption was common in response to P fertilization. Prevailing low herbage nitrogen-to-phosphorus ratios -below 11:1 in 65% of unfertilized controls- suggest nitrogen may be limiting ANPP. In this legume-scarce ecosystem, P fertilization is unlikely to boost productivity and may pose an environmental risk. © 2024 Springer Nature MenosABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production.

Abstract:
The presence of Amaranthus spp. Plants showing symptoms caused by root-knot nematode infection were detected in soybean fields from the municipality of Palmitas, Soriano, and Colonia del Sacramento, Colonia - Uruguay. After weed plants collection with root knot nematodes, the causal agents were identified as Meloidogyne incognita and Meloidogyne javanica from their morphology, esterase phenotypes, and species-specific characterized sequence amplified region (SCAR) sequences. The modified version of Koch's postulates was used to confirm the pathogenicity of Meloydogine ssp. In Amaranthus species. Host capacity of Amaranthus species for root-knot nematodes aggravates the harmful potential of the presence of these plants in crop fields. Therefore, control of these weed species, which allow for the reproduction of these parasites, might be an important tool for its management. This is the first report of root-knot nematodes M. incognita parasitizing A. hybridus and A. tuberculatus; and M. javanica parasitizing A. palmeri, A. hybridus and A. tuberculatus in Uruguay. |
