“…labile, carbon are changed (Manna et al 2007;Bishop et al 2008;de Oliveira et al 2008); water stability of soil aggregates is increased (Grieve et al 2005); the consumption of Ca-compounds increases in relation to the degree of soil organic matter lability (Kolář et al 2007); nitrification increases (Dorland et al 2004); and few papers deal also with the problem of the relation between the labile soil organic matter and soil water (Kolář et al 2002). We are very sorry not to have found any paper solving the relation between the labile soil organic matter and its corresponding calcium carbonate equilibrium in soil water.…”

Abstract:In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate constant of their biochemical oxidation was determined in hot water extracts of the samples. The need of liming was determined by means of 2 methods. In soil solutions of these samples, all values necessary to evaluate their calcium carbonate equilibriums were determined. The soil samples were enriched with 3% of dry matter of two organic materials, farmyard manure and meadow clover meal, and were incubated at 25°C for 180 days under wetting above 50% of their retention water capacity, and after this procedure all analyses were repeated. Both methods were found to increase the need of liming in all three soils: the more labile the organic matter in 3% addition, the higher the need. The meadow clover matter was more labile than the farmyard manure matter. All three methods for the study of soil carbon lability yielded similar results while the potassium permanganate method was more sensitive than the dichromate one. Increases were observed in equilibrium [Cr(H 2 CO 3 * )] and in Langelier saturation index I s . This means that soil liming cannot be considered only as an adjustment to the soil acidity and supply of calcium to plants to meet their requirements, but also as a replacement of the spontaneous adjustment to calcium carbonate equilibrium of soil water, for which through mineralisation of labile organic matters in conditions of our experiment about 220 kg CaCO 3 per hectare of land were consumed on condition that it was not necessary to re-establish it. The process of Ca-compound consumption to establish the calcium carbonate equilibrium is controlled exclusively by the degree of mineralising organic matters lability while the influence of soil properties is only marginal. The same results were provided by the comparison of calcium carbonate equilibriums in nine Šumava brooks of the total watershed area 78 564 km 2 with the degree of lability of organic matters in their sediments in 1986, 2001 and 2004. A reduction in the intensity of agricultural production in 1986-2004 resulted in an increase in the stability of organic matters in the sediments, in a decrease in I s , and in a lower corrosivity of brooks water towards CaCO 3 . However, the quality of soils and their potential soil fertility decreased due to the loss of labile organic matters.

“…It is a speculated elucidation that molasses may easily be putrefied to create differences in soil respiration compared with control and other organics. Decaying the behavior of organics in soil fluctuates depending upon the substance and soil type as the microbial activity is regulated by the substrate's molecular complexity and soil factors, i.e., soil pH and nutritious status [62,63].…”

Less precipitation, high temperature, and minimal natural vegetation are characteristic of regions having an arid climate. The harsh environment massively destructs the soil structure of that area by burning soil organic carbon, leading to deteriorated soil nutritional quality, creating a significant threat to agricultural production and food security. Direct application of organic wastes not only substitutes lost organic carbon but also restores soil structure and fertility. This study was conducted to assess the impact of organic amendments, i.e., farm manure (FM), poultry manure (PM), molasses (MO), and Exo-Poly Saccharides (EPS) producing rhizobacterial strains i.e., M2, M19, M22 amalgams as treatments. To assess the impact of treatments on soil carbon and structure restoration to hold more water and nutrients, a 42-day incubation experiment using a completely randomized design (CRD) under the two-factor factorial arrangement was conducted. Macro aggregation (0.25 to >1 mm), carbon retention in macro aggregates, active carbon (dissolved organic carbon, a mineral-associated organic carbon, microbial biomass carbon), total organic carbon, the carbon mineralization activities, and water retention capacities were observed to be highest in soils that were treated with (FM + M2, FM + M22, PM + M19, and MO + M19). Finally, we conclude that organics mineralization by microbial actions releases organic glues that not only impart particle aggregation but also conserve organics as aggregate entrapped carbon. Amalgamated application of microbe–manure combinations directly impacts soil structure and organic carbon contents, but in an indirect scenario, it improves the fertility and productivity of the soil. Therefore, it is strongly recommended to use organic manures and microbes in combination to restore structurally degraded lands.
