“…The significant differences by residue removal rate in fPOM and tPOM in aggregate size groups that were not significant for SOM (Groups 2, 5, 6 representing <0.42, 0.42-0.84, 0.84-2.0, 2.0-6.4, 6.4-19.2, >19.2 <0.42, 0.42-0.84, 0.84-2.0, 2.0-6.4, 6.4-19.2, >19.2 mm, respectively. and 6), suggest that fPOM and tPOM are more sensitive indicators of changes in production management than SOM over a short period of time (Cambardella and Elliott, 1992;Griffin and Porter, 2004). In fact, Wilhelm et al (2007) emphasized the slow response of SOM to improved sou management.…”

“…During the potato phase of the rotation the soil is intensively tilled and undergoes other mechanical operations (hilling, spraying, fertilization, vine-kill, and harvesting). This intensity can lead to reductions in soil organic carbon concentration and structural stability and adversely affect yield potential [14][15][16].…”

“…Griffin and Porter [16] examined the results of a long-term trial to assess the effect of cover crops, green manure, and amendment application frequency on soil carbon and nitrogen pools. They concluded cover crop and green manure had little impact on total carbon and nitrogen content.…”

“…Similar findings were reported by Luce et al (2013) with significant increases in the labile fractions of N attributed to both recycling of N-rich residues and biological N fixation after legume introductions; they highlighted that PON is the N form most sensitive to management-induced changes and has the potential to predict N availability for plant growth. Furthermore, Griffin and Porter (2004) showed that the inclusion of red clover as a cover crop in 2-year potato (Solanum tuberosum) rotations increased the proportion of total soil N as PON by 1,320% compared with rotations that did not contain a legume cover crop. In the deepest soil horizon (50-100 cm) of the leucaena-grass pasture, POC:PON ratio was considerably higher than in other treatments associated with the high POC concentration that might be formed by deep roots of leucaena.…”
