Effect of long-term application of manure and fertilizer on biological and biochemical activities in soil during crop development stages

Effect of Cultivation on Organic Carbon Pools and Nutrient Availability in Soil under Different Land Use System: A Review

“…Lakaria et al, (2012) reported that forest and organic farming systems have higher SOC content but the mineralization rate was found to be the minimum as compared to farmer's practices. An increase in SOC levels is directly linked to the amount and quantity of organic residues return to the soils (Mandal et al, 2007). After each change in the land use system a new quasi-equilibrium stage is arrived over a period of constant management in terms of new land use pattern, vegetation cover and management practices (Bhattacharyya et al, 2008).The dynamics of SOC with change in land use and management can better be explained by the way C is allocated in different fractions of soil organic matter (Tan et al, 2007).…”

“…The distribution of soil organic carbon (SOC) within different pools is an important consideration for understanding its dynamics and diverse role in ecosystems (Mandal et al, 2007 andBenbi et al, 2010). As an essential indicator of soil fertility, SOC and its different fractions have an important role in determining soil chemical, physical and biological properties.…”

Integrated Nutrient Management of Peppers (Capsicum annuum L.) in 21st Century - A Review

“…Lee et al, (2006) analyzed the effects of swine manure compost applied at low, medium and high rates vis-a-vis control (chemical fertilizers) on soil health indicators viz., bulk density, aggregate stability, organic carbon content, soil pH, available N, P, and K, extractable Cu and Zn, and microbial biomass and advocated that manure compost improved the soil quality. Mandal et al, (2007) also revealed that a balanced application of NPK + FYM gave the highest value for the Soil microbial biomass carbon (SMBC) and nitrogen (SMBN) as compared to control (no manure or fertilizer). Similarly, Manna et al, (2007) reported that SMBC, SMBN and acid hydrolysable carbohydrates (HCH) were greater in NPK + FYM and NPK + lime as compared to other treatments.…”

Soil Enzyme Activities, Microbial Diversity and Available Nutrients Status of an Alfisol under Long Term Fertilization

“…Functional diversity (e.g., microbial activity) is significant, because 80-90% of the processes in soil are reactions mediated by microorganisms (Nannipieri andBadalucco, 2003 andLivia Bohme et al, 2005). Among agricultural practices, ploughing, manuring and fertilization and crop rotation have beneficial, harmful or neutral effects on the trinity formed by plants, soil organisms (microbes and fauna) and soil (Bowen andRovira, 1991 andMandal et al, 2007).…”
