“…Kuzyakov & Xu (2013) reported an intense competition between plants and microorganism for mineralizable N, resulting in its wide variation. The lowest P recorded in PGS could be due to greater P requirement in pulses and potato, however, a contrasting pattern was noted for VGS, RWGS, and MGS, wherein, increased P status in soil was recorded (Table 3), which could be the result of an overdose of P fertilizers (Wang, Shi, & Li, 2019). The lower K requirement in pulses compared to other crops could be a reason for a higher extractable K in PGS.…”

In the last two decades, the productivity of the rice–wheat growing system (RWGS) in the upper Indo‐Gangetic Plains of India has come to a plateau, and, as a result, farmers are now shifting to other crop growing systems (cropping sysytems) to achieve a higher net productivity. Inclusion of other cropping systems in place of the rice–wheat system affects overall crop productivity; however, there is dearth of information with respect to nutrient index (NI), microbial diversity, and soil quality. This study was carried out to assess how NI, microbial diversity, and soil quality changed after replacement of rice–wheat by a vegetable growing system (VGS), pulse growing system (PGS), potato growing system (PoGS), and a mustard growing system (MGS). An analysis of 307 soil samples from these crop growing systems revealed a soil pH range of 6.58–8.87 with 75.3% soils falling within the low category of mineralized N, and low NI (<1.67). The highest NI, enzymatic activity, and microbial diversity was recorded under PGS, which restored 34.2, 24.1, and 10.2% greater soil organic carbon (SOC) than other systems, and had a better carbon substrate oxidation rateand mineralized N than PoGS. The diversity indices peaked under PGS followed by VGS due to greater SOC, mineralized N, higher microbial counts, and more soil enzymes. Among the different crop growing systems the soil quality index (SQI) ranged from 0.647 (for PoGS) to 0.783 (for VGS) . The silt content, SOC, Zn, TN, acid phosphatase activity, available P, and total culturable fungi were the key soil indicators across all the crop growing systems. SOC is the most important and viable indicator for all the crop growing systems that affected microbial dynamics and soil quality. The greater SQI under VGS was due to the addition of organic manure and augmented SOC, P, and Zn availability. In contrast, the highest microbial and enzymatic activities, and functional diversity was recorded under PGS mainly due to greater edaphic variables. It is concluded that the pulse growing system (PGS) is the best for maintaining higher NI, and improving microbial and functional diversity.

“…They found increased available soil phosphorus in protected cultivation of vegetables than openfield cultivation. Protected or Greenhouse vegetable Cultivation resulted in high levels of available phosphorous inside polytunnel than in the open field (Wang et al, 2019). The available build-up of available Phosphorus might be due to the influence of organic matter in increasing the labile phosphorus in the soil through the complexing of cations, which are responsible for the fixation of phosphorus .…”

A study was conducted to assess protected vegetable crop cultivation effects on soil nutrients status in Byas municipality of Tanahun, Nepal. For the study, polytunnel and playhouse were taken as treatments of protected vegetable crops cultivation, which was compared with open field cultivation, considered as control. Soil samples from each plot were sampled from 11 polytunnels, 11 polyhouses and 11 open fields consisting a total of 33 composite soil samples through stratified random sampling techniques from 20 cm soil depth in each plot. Analysis of soil samples was done in the laboratory for chemical properties. MS-Excel and R-Studio were used for data analysis. The results showed that soil nitrogen was 0.25% in the polytunnel, 0.18% in the polyhouse and 0.15% in the open field. Similarly, available potassium was 475.99 kg/ha in the polytunnel, 281.73kg/ha in the polyhouse and 143.13 kg/ha in the open field. Likewise, Available phosphorus was 266.8 kg/ha in the polytunnel, 239.84 kg/ha in the polyhouse and 140.06 kg/ha in the open field. Soil organic matter was found at 5.1% in the polytunnel, 3.6% in the polyhouse and 3.2% in the open field. Soil pH was found 6.9 in the polytunnel, 6.8 in polyhouse and 6.6 in the open field which showed slightly acidic or neutral soil pH. The research findings showed that soil nitrogen, available phosphorus and potassium and soil organic matter were maximum in polytunnels followed by polyhouses whereas open fields had minimum soil nutrient contents. Hence, it was concluded that protected vegetable crop cultivation had direct effects on soil nutrient status. It showed a vital role in the prevention of soil nutrients loss and management of soil fertility status in vegetable crops cultivation areas in mid-hills.

“…Phosphorus (P) is a vital element in vegetable production, playing a crucial role in promoting root growth and increasing yields ( Li et al., 2016 ; Wang et al., 2019 ; Bindraban et al., 2020 ). The demand for P in crop production in China led to the rapid growth of the P fertilizer industry since the late 20th century ( Li et al., 2015 ).…”

IntroductionIn contemporary agriculture, the substitution of manure for chemical fertilizer based on phosphorus (P) input in vegetable production has led to a significant reduction in P fertilizer application rates, while, the effect of manure substitution rates on soil P transformation and uptake by root remain unclear.MethodsThis research conducts a pot experiment with varying manure substitution rates (0%, 10%, 20%, 30%, 40%, 50%, 75% and 100%) based on P nutrient content to elucidate the mechanisms through which manure substitution affects P uptake in pepper.Results and discussionThe result showed that shoot and root biomass of pepper gradually increased as manure substitution rate from 10% to 40%, and then gradually decreased with further increases in the substitution rate. Soil alkaline phosphatase activity and arbuscular mycorrhizal (AM) colonization gradually increased with manure substitution rates improvement. Specifically, when the substitution rate reached 30%–40%, the alkaline phosphatase activity increased by 24.5%–33.8% compared to the fertilizer treatment. In contrast, phytase activity and the relative expression of phosphate transporter protein genes in the root system was declined after peaking at 30% manure substitution. Additionally, soil available P remained moderate under 30%–40% substitution rate, which was reduced by 8.6%–10.2% compared to that in chemical fertilizer treatment, while microbial biomass P was comparable. In the current study, soil labile P similar to or even higher than that in chemical fertilizer treatment when the substitution rate was ≤40%. Correlation heatmaps demonstrated a significant and positive relationship between soil available P and factors related to labile P and moderately labile P.ConclusionThis finding suggested that substituting 30%–40% of chemical P with manure can effectively enhance root length, AM colonization, soil enzyme activity, soil labile P, and consequently improve P uptake in pepper. These findings provide valuable insights for future organic agricultural practices that prioritize P supply, aiming to standardize organic P management in farmland and achieve high crop yields and maintain soil health.
