“…A profound increase in microbial population was observed in organic manure addition with inorganic fertilizer and foliar spray of zinc applied plots as compared to only chemical fertilizer application because organic matter serves as a source of the nourishment and also as a substances for decomposition and mineralization of nutrients which creates a favorable condition for growth of microbes in the soil. Similar findings were also observed by Nandy et al [28], Bahadur et al [29], Kumari et al [30], Kumar et al [24] and Raliya and Tarafdar [31][32,33].…”

The field experiment was conducted during Kharif season 2022 at Student’s Instructional farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya Uttar Pradesh, India. The experiment was laid out in Randomized Block Design (RBD) with three replications and ten treatments. The experiment comprised of ten treatments viz., T1: Control, T2: 100% RDF (150, 60, 40 N, P2O5, K2O kg ha-1), T3: 100% RDF + 25 kg ZnSO4 ha-1 soil application, T4: 100% RDF + 0.5% ZnSO4 spray at tillering stage, T5: 100% RDF + 0.5% ZnSO4 spray at tillering stage + PI stage, T6: 75% RDF + 25 kg ZnSO4 ha-1 soil application, T7: 75% RDF + 0.5% ZnSO4 spray at tillering stage, T8: 75% RDF + 0.5% ZnSO4 spray at tillering stage + PI stage, T9: 75% RDF + 25% FYM-N +0.5% ZnSO4 spray at tillering stage + PI stage and T10: 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application. The application of 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application has non-significantly effect on Bulk density, pH, Electrical Conductivity of soil after harvest of rice crop. The application of 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application has significantly influenced Organic carbon, Available N, P, K and Zn in soil.

“…The urease activity variation is instigated by modification in soil physicochemical parameters such as the content of moisture and organic matter and the accumulation of nitrogen, which is regarded as the urease substrate in soil. Kumari et al, 2017 also noted a non-significant correlation between urease activity and soil pH [ 40 ].…”

The soil pollution as a product of xenobiotics, industrial action, agricultural chemicals, or inappropriate disposal of waste can change the natural environment of soil indices and trigger life-threatening situations. Soil enzyme activity is the suitable bio-indicator or parameter for monitoring soil pollution due to their sensitivity that quickly responds to any soil disturbances. Also, they are known to play an essential role in maintaining soil health and a quality environment. This study aimed to determine the levels of enzyme activity in soil from polluted and unpolluted sites and study the relationship between the physicochemical properties and soil enzyme activity to manage soil pollution. Four selected enzymes (Urease, Invertase, Catalase, and Phosphatase) were examined for their activity from forty samples using the assay method for 24 h; the colorimetry spectrophotometer measured their activity. The obtained data revealed that Invertase activity was a predominant enzyme in all soil samples. Whereas, the urease activity had obtained in low amounts for all collection sites, especially on Site A1. Soil pH had discovered to range between 5.8 and 8.51, moisture content values recorded to vary from 0.12% to 9.09%, and soil organic carbon recorded to fluctuate between 0.08% and 1.54%. Urease and phosphatase activity correlated positively with all soil physicochemical properties except for moisture content, which correlated negatively (r = −0.297; p ≥ 0.05). The invertase activity negatively associated all soil physicochemical properties, excluding the moisture content that correlated positively and significantly with invertase activity. We noted that the dumpsite soil contains low enzyme activity levels, which might attribute to the type of waste disposed off. Also, only the phosphatase activity reported correlating positively with all examined physicochemical parameters entirely.

“…Fungi also produce acid phosphatase and most bacteria produce alkaline phosphatase. Other factors like soil organic carbon, total nitrogen, soil pH, clay content, and moisture can also influence soil enzymes (Gu et al, 2009;Kumari et al, 2017). Therefore, by utilizing enzyme activities as indicators, researchers can assess the effects of the application of organic materials on soil fertility, nutrient cycling, soil health, organic residue decomposition, and plant physiological processes in paddy fields.…”

PurposeThis study investigates the influence of incorporating Azolla, rice straw, and NPKS fertilizers on phosphorus use efficiency (PUE) and rice productivity in lowland paddy fields. Despite Azolla’s well-known role as a nitrogen-fixing aquatic fern in rice production, its specific impact on PUE remains unclear. The primary objective is to explore diverse treatment combinations to identify synergies that enhance both PUE and overall rice productivity.MethodsThe study was conducted at Mkula Irrigation Scheme in the Kilombero Valley, Tanzania; the field experiment employed a randomized complete block design with 13 treatments and three replications. Treatments comprised various combinations of Azolla, rice straw, and chemical fertilizers, incorporating 50% and 100% rates of nitrogen (N) applied with phosphorus (P), potassium (K), and sulfur (S).ResultsThe study reveals the substantial impact of Azolla application on total nitrogen, available phosphorus, and exchangeable potassium levels in the soil. Particularly noteworthy were treatment combinations involving Azolla, rice straw, and reduced rates of synthetic nitrogen, along with specific P, K, and S applications, which exhibited the highest phosphorus uptake and PUE. Specifically, combining rice straw and Azolla with reduced N rates, alongside 30 kg P ha−1 + 30 kg K ha−1 + 20 kg S ha−1, resulted in the highest phosphorus uptake (73.57 kg/ha) and PUE (46.24%).ConclusionIntegrated nutrient management, incorporating rice straw and Azolla alongside synthetic fertilizers, demonstrates synergistic effects on phosphorus uptake and efficiency while maintaining soil quality. The study underscores the potential of such integrated strategies to optimize PUE and contribute to sustainable rice production in lowland paddy fields.
