“…working with turfgrass of Zoysia japonica (emerald grass), found value of macropores in the soil evaluation of 8.68%. Arrieta et al (2009) in a golf course composed of Bermuda grass, observed macroporosity of 9.11% and 10.10% in different areas. Also, in a study with soil physical characterization for the development of emerald grass, observed the value of 12.67%, being only medium sand (50%) + organic compost (50%) above that mentioned, and the other treatments, below.…”

Bermuda grass are the most widely used today in high performance sports fields, the cultivar “Tifton 419” is widely indicated for installation in these areas, however, there is no official a recommendation in the literature of the best substrate for the implantation of this species, and research is needed to meet this demand. In this way, the objective of this study was to evaluate the influence of substrates in the development of the “Tifton 419” sporting lawn. The experiment was conducted in field with grass carpets implanted in black plastic containers (volume 8.46 L), in a completely randomized design with five substrates and 12 replicates, with treatments: soil (100%), medium sand (100%), soil (50%) + medium sand (50%), soil (33%) + medium sand (33%) + organic compost (33%) and medium sand (50%) + organic compost (50%). Macro and microporosity, total porosity, density, chlorophyll content (a + b) and fresh and dry leaf mass were evaluated. The results showed that there was influence of the substrate on the development of the turfgrass, with the medium sand (50%) + organic compost (50%) presenting greater increases of fresh and dry mass (1.09 and 0.44 kg m-2), which may lead to higher maintenance costs of the cut, and soil (33%) + medium sand (33%) + organic compost (33%) presented good results of the analyzes performed, being the one recommended for the development of the cultivar “Tifton 419” in sports fields.

“…Therefore, all the treatments presented results above the above. Arrieta et al (2009) evaluating the physical properties of the soil in a golf area for the development of Cynodon spp. found values of 40.52% and 40.75%, results close to that of the present study and observed 36.67% of micropores in the soil where the emerald grass was implanted.…”

“…Its intrinsic characteristics, such as photosynthetic C4, rapid growth and high seed production, which can germinate under a large range of soil conditions in terms of salinity, pH, compaction and temperature, make this species extremely competitive (Ismail et al, 2002;Chauhan and Johnson, 2008;Takano et al, 2016a). Goosegrass thrives mainly on roadsides and machinery tracks, due to the compaction of the soil in these places and the absence of other plants around it (Arrieta et al, 2009). …”

“…In addition to the chemical management, other control methods should be considered to avoid the selection of short-term multiple resistance. The use of cover crops (Adler and Chase, 2007), soil tilling (McCollough et al, 2016) and rapid growth of the crop (Arrieta et al, 2009) are alternative management methods that also decrease the population size of weeds in the field.…”

Chemical Control of Glyphosate-Resistant Goosegrass

et al. 2018

-The use of mixtures and rotation of herbicide modes of action are essential for herbicide resistance management. The purpose of this research was to evaluate different pre-and post-emergence herbicides to control goosegrass in soybean and corn. Four greenhouse experiments were conducted, one in preemergence and the three others in post-emergence. In pre-emergence, the number of emerged plants and the control percentage at 20, 35 and 50 days after application were evaluated. In post-emergence, the control percentage was evaluated at 14 and 28 days after application on plants with one tiller and four tillers. The use of residual herbicides to control glyphosate-resistant goosegrass is a very important tool for its effective management. The application stage is also crucial for post-emergence efficacy. Paraquat and [paraquat + diuron] are effective in controlling this species. The application of ACCase inhibiting herbicides alone seems to be more effective than their associations with glyphosate, especially in plants with four tillers. HPPD inhibiting herbicides have high synergism with atrazine and not with glyphosate. Keywords

“…This is because there are conflicting requirements during soil compaction to facilitate plant growth on the one hand and to minimize rainfall infiltration on the other. From an ecological point of view, it is more favourable to compact soil at a relatively loose density (RC as low as 70%) so that plant roots can penetrate to deeper depths to trace as much water as possible from the groundwater table (Merotto and Mundstock 1999;Arrieta et al 2009). This would however promote rainfall infiltration, adversely generating a larger volume of leachate beneath a landfill cover, for instance.…”

Effects of soil density on grass-induced suction distributions in compacted soil subjected to rainfall

2014

Grass is recognized as being beneficial in reducing rainfall infiltration in some kinds of surface cover systems such as landfill cover, because rainwater discharges as surface runoff due to reduced water permeability caused by evapotranspirationinduced soil suction as well as foliage interception. However, the distributions of grass-induced suction in various compacted soils during rainfall are rarely reported. Moreover, it is not straightforward to determine an optimum soil dry density for minimizing rainfall infiltration and at the same time encouraging plant growth. This is because there are conflicting requirements for vegetated cover systems, i.e., compacted soil should not be too dense as to impede root growth, while on the other hand to minimize infiltration. This study thus aims to investigate, quantify, and compare grass-induced suction distributions in silty sand compacted at different densities when subjected to artificial rainfall in the laboratory. A grass species, Cynodon dactylon, which is common in many parts of Asia, was selected for testing. Compacted soil with and without a growing grass patch was tested at three relative compactions (RCs) of 70%, 80%, and 95%, in six test boxes. Test results reveal that at an RC of 95%, suction (40 kPa) retained in vegetated soil after rainfall is 100% higher than that (20 kPa) in bare soil. Among the vegetated soil compacted at the three RCs, suction retained was the highest at an RC of 95% (40 kPa), whereas suction decreased to 0 kPa at an RC of 70% after rainfall. As the average depth of grass roots decreased by 36% due to an increase in RC from 70% to 95%, the depth of influence of suction for vegetated soil at an RC of 95% reduced to less than half of root depth, which was the shallowest among the three compacted soil specimens.Résumé : L'herbe est reconnue comme étant bénéfique pour réduire l'infiltration de l'eau de pluie dans le cas de certains types de système de recouvrements de surface, comme les couvertures sur les sites d'enfouissement. En effet, l'eau de pluie s'écoule à la surface en raison de la faible perméabilité à l'eau, qui est causée par la succion du sol induite par l'évapotranspiration et par l'interception de l'eau par les feuillages. Cependant, les distributions de la succion induite par l'herbe dans différents sols compactés durant les précipitations sont rarement rapportées. De plus, il n'est pas évident de déterminer une densité sèche optimale du sol pour minimiser l'infiltration de l'eau de pluie et en même temps favoriser la croissance des plantes, puisque les critères pour les couvertures de végétation ne sont pas les mêmes, c'est-à -dire que le sol compacté ne devrait pas être trop dense pour empêcher la croissance des racines mais devrait tout de même minimiser les infiltrations. Cette étude vise à investiguer, quantifier et comparer les distributions des succions induites par les plantes dans un sable silteux compacté à différentes densités lorsque soumis à des précipitations artificielles en laboratoire. Une espèce d'herbe, ...
