It is also an integrated reflection of various
soil type transformations.
Mean loads of P fractions and SS in surface runoff, and soil chemical and physical properties, were tested for normality and log-transformed if necessary before an ANOVA was performed, fitting terms for
soil type, treatment, aggregation (dispersed v.
Sixteen days after infestation (11 Mar 2007), 6 plants in each
soil type (marl soil or potting medium) were flooded by placing each plant container into a larger 19-L plastic container filled with tap water with the water level maintained 10 cm above the soil surface (24 cm total depth).
Both groundnut cultivars did not nodulate in this
soil type (Fig.
However, parameters such as AM fungi, Azotobacter, rock phosphates and
soil type have significant influence on the plant growth performance and barbaloin yield.
Statistical analysis.--We used mixed-model analyses of variance (PROC MIXED, SAS, 2003) to determine the effects of species,
soil type and water regime on the dependent variables: days to first germination, final % germination, shoot height, total biomass and root/shoot ratio.
Five soils, representing four important
soil types in Estonia, Rendzic Leptosol (Rendzinas), Podzol (Sod-podzolic), Podzoluvisol (Brown pseudopodzolic), and Podzolic Gleysols (Gley-podzols), were investigated (Table 1).
Repeat the steps below for each
soil type. Treat each soil the same way.
To narrow his search, Fisher chose 140 sites--each with a unique combination of
soil type and rainfall--to chase down these large ant colonies.
Moisture: the moisture of the soil can be affected by local annual rainfall, time of year,
soil type and the orientation of garden.
Additionally, OLS determines
soil type and moisture content to estimate the strength of the area.
An example of this is a chart of yield points by
soil type. The goal of this chart would be to calculate the average yield for each
soil type.
