Interactive comment on “Scale and space dependencies of soil Nitrogen variability” by Ana M. Tarquis et al

چکیده

At the end of section 2.4: Finally, a statistical test was applied for each variable to determine if there was any significant trend with distance that would not allow the application of a straight multifractal analysis on the original data. The measure used was the coefficient of the slope of the regression line along the distance. This coefficient is derived using the least squares method and then compared to zero using the Student t-test. If the t value is less than a critical t value at the 95% level for the degrees of freedom, then the slope is considered to be zero.

Interactive comment on “ Scale and space dependencies of soil Nitrogen variability ”

The manuscript explores the effect of the N fertilizer applied to a previous horticultural crop on the subsequent, unfertilized, wheat crop: the different response of weight and nitrogen content of the cereal. The differences shown by the wheat crop after the fertilization of the previous crop were already examined by several of the authors using the wavelet technique (Milne et al. 2010). The n...

Multiscale Entropy-based Analysis of Soil Transect Data

A deeper understanding of the spatial variability of soil properties and the relationships between them is needed to scale up measured soil properties and to model soil processes. The object of this study was to describe the spatial scaling properties of a set of soil physical properties measured on a common 1024-m transect across arable fields at Silsoe in Bedfordshire, east-central England. P...

Interactive comment on “Soil respiration at mean annual temperature predicts annual total across vegetation types and biomes” by M. Bahn et al

Ref #1: ‘With this work, the authors demonstrate that annual soil respiration can be estimated by measuring soil respiration at mean annual temperature at sites which are not water limited. At seasonally arid sites, a correction factor based on the ratio between precipitation and potential evapotranspiration needs to be used. This work is, thus, extremely useful in that it proposes a feasible m...

2) Section 1, line 84: “in the study the relationship of the temporal and spatial variation of soil moisture is determined by establishing its controlling factors . . .” The sentence is revised as “in this study the relationship between variation of soil moisture and its controlling factors (e.g. topography and precipitation) is established.” That mean the modified wetness index. Line 110: “. ....
