The restoration of dry forest ecosystems in the Squamish Forest District in the past has focused on treating stands with no prior history of selective harvest and containing a large population of remnant historical stand structure. Many 60 to 90 year old stands that date to turn of the century selective harvest operations also exist in the district. These stands contain very high densities of D...

The use of mulching, compost, and their interaction on organic residue (OR) decomposition rate (k), time decay, primming effect, soil organisms’ community composition was tested in a 16-year P. pyrifolia field experiment conducted from January 2020 to June 2021. A 2 × factorial design used with compost mulching as the two factors within four blocks. OR characterized by using litter bags differe...

The use of plastic mulching and high frequency hydroponic drip irrigation (intensive production methods) watering cycle may increase tabasco pepper crop per unit area. To test this hypothesis, two randomized block experiments were conducted in a greenhouse, using 2 × 4 factorial scheme with contrasting soil types (sandy loam loamy soil), conditions cover (SC), no (NC) at four frequencies: 1, 3,...

Among soil management practices, Mulching, synthetic and organic, appears as an alternative, they can improvements properties plant development, however, practice little explored farmers. For this reason, ...

The simple leaves of deciduous forest trees in temperate zones have more irregular and asymmetric shapes than comparable non-deciduous the tropics subtropics. These manifest as lobes sinuses species Quercus Acer, well greater bilateral asymmetry Ulmaceae Betulaceae, serrated margins many species, frequency compound generally (Fraxinus Carya). modifications may contribute to an early transition ...
