The transition from conventional to organic and low-input farming is accompanied by changes in an array of soil chemical properties and processes that affect soil fertility. Fundamental differences, both qualities and quantitative, in the flow and processing of nutrient result from the use of cover crops, manure and compost applications, and reduction or elimination of synthetic fertilizers and pesticides. These changes affect nutrient availability to crops either directly by contributing to nutrient pools or indirectly by influencing the soil chemical and physical environment.

More generally, Walter et al. (2002) tested the spatial cross-correlation between weed species and several soil properties. Certain weeds were correlated with specific soil chemical properties (e.g. P, pH) however, other species did not show consistent correlation with soil types between fields and sampling times, and some were correlated with more than one soil property. The most consistent relationship was between weed density and clay content. This result suggests that weeds have different resource requirements and that modifying soil conditions to manage certain weeds may promote others. 

Intact soil cores (6.7 cm i.d.) were taken with spilt spoon at depths of 1 to 2 meters from a field test site located approximately 50 km east of Cincinnati, Ohio. The soil in this interval consists mainly of quartz (60%) and clay minerals (35%) with minor amounts of plagioclase and potassium feldspar. The majority of clay is illite and smectite, with minor amount of kaolinite. Soil chemical properties were analyzed prior to, and after, electroosmosis, in order to evaluate the effects of electroosmosis on the distribution of elements within the soil column. Sampled cores were wrapped in aluminum foil and stored at 12°C until the EO cell was assembled. 

Mineralization of organic residues in soil is mainly carried out by an extremely diverse heterotrophic community referred to as the soil microbial biomass. The soil environment is a rather peculiar natural environment for the growth of microorganisms, in that they have had to adapt to quite extreme growth-limiting factors (a) discontinuous availability of substrates and water and (b) high variability of soil chemical properties (pH, temperature, oxygen supply) that can vary in the soil environment on both the micro and macro scales (Jenkinson and Ladd, 1981).

The general improvement in soil chemical properties after burning is mainly due to constituents in the ash that provide substantial inputs of bases and other elements to the soil. Also, heating caused by burning may contribute to the improvement of soil fertility by enhancing the mineralization of elements (N, Ca, Mg, and P) formerly linked and complexed with organic matter (Giovannini et al. 1990).
