Assessment of soil properties by organic matter and EM-microorganism incorporation

Abstract

SUMMARYProperties of a claim loam soil, collected in Aranjuez (Madrid) and enriched with organic matter and microorganisms, were evaluated under controlled temperature and moisture conditions, over a period of three months. The following treatments were carried out: soil (control); soil + 50 t ha -1 of animal manure (E50); soil + 50 t ha -1 of animal manure + 30 L ha -1 of effective microorganisms (E50EM); soil + 30 t ha -1 of the combination of various green crop residues and weeds (RC30) and soil + 30 t ha -1 of the combination of various green crop residues and weeds + 30 L ha -1 of effective microorganisms (RC30EM). Soil samples were taken before and after incubation and their physical, chemical, and microbiological parameters analyzed. Significant increase was observed in the production of exopolysaccharides and basic phosphatase and esterase enzyme activities in the treatments E50EM and RC30EM, in correlation with the humification of organic matter, water retention at field capacity, and the cationic exchange capacity (CEC) of the same treatments. The conclusion was drawn that the incorporation of a mixture of effective microorganisms (EM) intensified the biological soil activity and improved physical and chemical soil properties, contributing to a quick humification of fresh organic matter. These findings were illustrated by the microbiological activities of exopolysaccharides and by alkaline phosphatase and esterase enzymes, which can be used as early and integrated soil health indicators.Index terms: quality indicators, microorganisms, physical, chemical, and biochemical soil properties.(

The effect of landslide on soil organic carbon stock and biochemical properties of soil

“…Deposits of landslides are characterised by high variability of properties, especially the distribution and the amount of soil organic matter . The contents of soil organic matter are often used as an indicator of soil quality, and it helps determine the physical (Masri and Ryan 2006), chemical (Sebastia et al 2007) and biological properties of soil (Valarini et al 2003;Arandá et al 2015). Soil organic matter is used in the evaluation of soils in addition to biological indicators of soil quality (Flieβbach et al 2007).…”

The impact of a bio-fertilizer on the soil organic matter status and carbon sequestration—results from a field-scale study

“…Consequently, changes in soil management may lead to a decrease of organic matter content followed by a diminution in the sustainability of the soil, which can be expected over the long term (Valarini et al 2003). Increasing concern about the long-term productivity and sustainability Responsible editor: Zucong Cai of soil quality has emphasized the need to the develop management practices that reduce the potentially negative impact of agricultural activities in which proper OM management appears to be the most important factor (Chander et al 1997).…”

“…Previous research has indicated positive, rarely negative, and the lack of any significant influence of bio-fertilizers on soil physicochemical and biological properties (Kaczmarek et al 2008;Mayer et al 2010;Tejada et al 2011;Piotrowska et al 2012). While some, usually contradictory, results have been obtained in relation to the influence of bio-fertilizers on the organic matter content (e.g., Valarini et al 2003;Nisha et al 2007; Schenck zu SchweinsbergMickan and Müller 2009;Pardo et al 2010;Jakubus et al 2013), less is known about the fractional composition of humus (Valarini et al 2003), which impedes any further research in this field. Some researchers have noted the influence of biofertilizers on the acceleration of the humification of fresh organic matter that is introduced into the soil (Valarini et al 2003;Fatunbi and Ncube 2009;Piotrowska et al 2012).…”

Innovation of Organic Fertilizer and Pesticides Technology Based on Local-Natural Resources to Support Food Self-Sufficiency Sustainibility

“…The best solution to improve the condition of the land is using a solution of Effective Microorganism (EM), rice straw compost, organic fertilizers and pesticides that can be made by utilizing the materials around the house as well as farmers' fields. The solution based on the research results of the use of straw and Effective Microorganism (EM) to improve soil fertility either the physical, chemical and biological [6,8,14,15].…”

“…Organic fertilizers increases soil organic matter, that is a key role in the improvement of the physical, chemical and biological soil [3][4][5]. Mixing the crop residues and cattle dung compost by following giving EM solution of 30 L per hectare improved biological, physical, and chemical soil [6]. The rice production was increased by rice straw application on the rice field up to 32% [7].…”
