“…In this study, most enzyme activities were found to be higher in a frequently cultivated field compared to a fallow field, and higher in crop-rotated fields than in single-crop patterns. Kumar et al [84] also found higher enzyme activity in cultivated fields compared to those with a fallow period. Different rates of enzyme activity between spring cotton, spring maize, and winter wheat indicated that crop species and amount of residue return played important roles in controlling microbial activity.…”

Various cropping patterns are extensively used on the North China Plain, which greatly alter various soil properties. Although these soil properties respond differently to the different cropping patterns, little is known about the possible effects of cropping patterns on desalinized soils. To assess the effects of the different cropping patterns on soil properties and enzyme activities, a long-term field experiment was conducted at the Nanpi Agro-Ecological Station in Hebei Province, China. The cropping patterns under study were the single-cropping patterns of winter wheat (Triticum aestivum L.), spring maize (Zea mays), and spring cotton (Gossypium hirsutum), and the double-cropping pattern of winter wheat–summer maize (WW–SM), which is the predominant cropping pattern on the North China Plain. Soil samples were collected at a depth of 0–100 cm, depending on the soil properties. Our results indicated that soil available phosphorous (P) and available potassium (K) concentrations at 0–20 cm were greater than those of the subsurfaces. Soil organic matter declined with depth, and WW–SM had the highest amount in the deep levels. The WW–SM cropping pattern also generally showed greater levels of enzyme activities than did the single-cropping patterns, proving that diverse crops can enhance enzyme activities. Soil pH generally increased with depth despite there being no significant differences between the cropping patterns. No significant effects were observed on soil electrical conductivity (EC). However, EC generally increased with depth in spring cotton and winter wheat and declined in spring maize and WW–SM. Winter wheat had a significant aggregate size (<0.053 mm) at 20–40 cm depth and generally showed the lowest amount of nutrients. This study suggests that a fallow period allows the soil to regenerate its structure, whereas WW–SM enhances high soil organic matter in the deep soil layers and promotes increased soil enzyme activities. This indicates that crop rotation could sustainably exploit soil resources without reducing fertility over a long period. There is a need to incorporate different soil management practices for single-cropping patterns to increase their productivity, especially in spring maize, whose organic matter declined the most. Our results also show a need to diversify to different crop rotations to utilize their benefits and enhance soil productivity while increasing crop output.

“…The range of bulk density for surface soils varied from 1.45-1.67, 1.12-1.38, 1.10-1.27, 1.35-1.67, 1.10-1.39 and 1.10-1.20 mg m-3 in paddy-paddy, fallow-paddy, groundnut-paddy, paddy-cotton, paddygreengram and paddy-blackgram cropping systems (Fig 1 ) and CV was 14.24 and 11.74 per cent for bulk density in both surface and subsurface soils of different cropping systems. The lowest bulk density was found under paddyblackgram cropping system due to higher amount of added biomass from leguminous crops made soil loose, porous and less squeezed [13,14].…”

A study was carried out during 2021-22 in SPSR Nellore district of Andhra Pradesh, India to know the impact of major cropping systems on soil physical properties. A total of 240 soil samples (120 surface and 120 subsurface) under six major cropping systems such as paddy-paddy, fallow-paddy, groundnut-paddy, paddy-cotton, paddy-greengram and paddy-blackgram were collected and analysed for physical properties. The results revealed that the color of the soils ranged from pale red to very dark gray (2.5 YR 6/2 to 7.5 YR 3/1). The soils of study area were sandy clay loam, sandy loam, clay loam and clay in texture. Soils from paddy-paddy and paddy-cotton cropping systems recorded highest bulk density (1.55 mg m-3) in surface soils and paddy-cotton (1.66 mg m-3) cropping system in sub-surface soils whereas lowest bulk density observed in paddy-blackgram cropping system in both surface (1.13 mg m-3) and sub-surface soils (1.29 mg m-3). In surface and subsurface soils particle density was ranged from 2.45 mg m-3 in paddy-cotton and paddy-blackgram cropping system to 2.75 mg m-3 in paddy-cotton and paddy-greengram cropping systems. The soils of paddy-blackgram cropping system showed higher water holding capacity (54.65 and 49.71%, respectively) while the lowest was recorded in paddy-cotton cropping system in surface and sub-surface soils (31.39 and 28.28%, respectively). Volume expansion was found to be high in paddy-blackgram cropping system in both surface and subsurface soils (22.34 and 23.61%, respectively) while lowest volume expansion was noticed in paddy-paddy cropping system in surface soils (12.46%) and paddy-cotton cropping system in sub-surface soils (11.94%).
