Construction activities often involve removal of topsoil and compaction of the exposed soil by heavy equipments. Such compacted soils with low organic matter can lead to low infiltration and poor vegetation establishment. the objective of this study was to investigate the efficacy of tillage (shallow till) and compost on soil physical and biological properties in a hydroseeded lawn as a post-construction best management practice for soil compaction remediation. the experimental site received a total of four land treatments in five replicated trials and it was hydroseeded with common Bermuda grass: 1) No tillage + Compost (Nt-C), 2) No tillage + No Compost (Nt-NC;control), 3) tillage + Compost (t-C), and 4) tillage + No Compost (t-NC). Bulk density (BD), infiltration rate (IR), and wet aggregate stability (WAS) in each plot were measured to assess soil physical properties while soil organic matter (SOM) and enzyme activity (β-glucosidase, acid-phosphatase, and alkaline-phosphatase) were measured for soil biological properties. Over a 15-months of monitoring period, the shallow tillage loosened the soil initially, but its effect on BD without compost was diminished to control plot level (Nt-NC) within 4 months after hydroseeding. Both tillage and compost led to an increase in IR, and it remained higher than control by 2 - 3 times throughout the observation period. the WAS and β-glucosidase activity decreased in tilled plot unless there was compost application. turfgrass showed greener leaves and aggregated roots in the compost-amended plots (Nt-C and t-C). Our results suggest that compost application plays a key role in improving soil physical and biological properties in hydroseeded lawns from construction sites.

OBJECtIVE:the functional integrity of the blood-testis barrier (BtB) in male mice exposed to Cr(V) was studied in order to clarify the mechanism underlying testicular injury.;MEtHODS:Adult male mice were subcutaneously injected repeated doses of 8.02 micromol (0.5 ml) of Cr/*** for 5 days. Animals receiving a similar volume of bis(hydroxyethyl)-aminotris(hydroxymethyl)methane buffer (Bt) were used as controls. the animals were sacrificed on day 6 and small fragments of seminiferous tubules, approximately 8-10 mm length, were incised and sutured at both ends. they were exposed in vitro to horseradish peroxidase-containing culture medium for 10 minutes. tissues were then fixed and processed for ultrastructural studies.;RESULtS:Controls and Cr(V)-treated group resulted in the uptake of the tracer by Sertoli cells. However, the major finding consisted in the permeability of the BtB only in the Cr(V)-group, as evidenced by the presence of the tracer within the junctions between the neighbouring Sertoli cells.;CONCLUSIONS:the BtB is disrupted in mice submitted to Cr(V). the permeability of the BtB is a crucial feature to be investigated for the understanding of lesions within the seminiferous tubule.

Over the past century or more,traditional uses of seaweeds began and initially comprised the simple collection,sorting and drying of seaweeds harvested from the wild,or cast upon the beach,for use as soil“manure/fertilizer/improver”.Some macroalgae were used for unprocessed food purposes and subsequently harvested and cultivated biomasses of selected brown and red seaweeds becameindustrially processed to yield alginates,mannitol,iodine,agar,agarose,carrageenan,and more recently biostimulants,*** from various seaweeds are very diverse and are commonly applied in a range that includes textiles and dying,food/feed and supplements and specialized medical applications.
