The total carbon was typically <8.4%, and declined with depth, except for the Organic Soils
; in these soils total C was >20% and reached 57% in the sub-surface of the Rukuhia soil, which has developed in weakly decomposed fibrous peat.
In this experiment 10 tonnes ha-1of each organic soil
amendments sources was used on sole treatments and half rate (5 tonnes ha-1) when combined mineral fertilizer.
Since 2008, the National Soil Project has been measuring the organic soil
content of soil throughout the nation.
Kazemian, "Experimental investigation on geomechanical properties of tropical organic soils
and peat," American Journal of Engineering and Applied Sciences, vol.
The paper presents an application of the geoelectrical method in organic soils
occurring in the area of a designed investment.
It has been found that the organic soil
exists here at a depth of 10 to 25 ft.
Data presented in Table-2 clearly reflects that organic soil
have more fungal species compared to inorganic soil but their diversity decreased at post-harvesting stage than that of pre-harvesting stage.
The samples were treated in the laboratory with 10% KOH, sieved to remove larger pieces of plant material, undergone acetolysis and heavy liquid separation in zinc bromide/hydrochloric acid for the samples in which some mineral residue was present especially in some clayey peat or organic soil
samples (Wood et al.
The holes allow air and water to get in and should then be filled with a mix of sharp sand and organic soil
conditioner to stop them closing up.
The holes you make allow air and water to get into the grass roots and should then be filled with a mixture of sharp sand and organic soil
conditioner to stop the holes from closing up.
At our study site, eggs have been found in two substrate types (broken shell/sand and dark organic soil
) and likely experience a broad range of hydric conditions.
Fill the trench half-full of rich organic soil
with the top slightly mounded.
