“…Maximum activity of acid and alkaline phosphatase was observed at 60 DAS due to increased root exudates production at critical crop growth stages. These results were supported by [23] who observed higher phosphatase activity during the initial days of incubation.…”

An experiment was conducted at Zonal Agricultural and Horticultural Research Station, Hiriyur with four different nutrient management approaches during 3 consecutive years 2019-20, 2020-21 and 2021-22. The experiment consists of 4 treatments, viz., T1 – Natural farming - Seed treatment with Beejamrutha + Ghana jeevamrutha @ 1000 kg ha-1 before sowing + Jeevamrutha @ 200 L ha-1 @ 15 days interval + mulching at 30 DAS; T2 – Organic farming - Seed treatment with Rhizobium + PSB + N equivalent basis of vermicompost; T3 – Package of Practice – Recommended dose of N, P2O5, K2O and FYM; T4 – Farmers practice - FYM @ 7 t ha-1 and 45: 115 kg ha-1 N, P2O5, respectively in a randomized complete block design (RCBD) with 5 replications. The results revealed that the application of organic manures such as vermicompost and FYM and concoctions like jeevamrutha and ghanajeevamruta for 3 years has improved soil biological properties in both seasons. Treatments varied significantly among different nutrient management approaches with respect to dehydrogenase, urease, phosphatase and arylsulfatase activity in the rhizosphere soil of the summer and kharif maize. Significantly higher enzyme activities were noticed in organic farming treatment followed by package of practice and natural farming treatment. The lowest activities were observed in farmers practice treatment. Similarly, microbial biomass carbon, nitrogen, phosphorus and sulphur were highest in organic farming treatment and lowest in farmers practice treatment.

“…This might be due to higher microbial activity and availability of carbon substrate as compared to solitary application of fertilizers. Increase in DHA with addition of FYM was also reported in several studies (Bastida et al 2012, Srinivasan et al 2016. due to lack of sufficient substrate.…”

“…Under balanced fertilization, higher microbial population also resulted into more secretion of enzyme and increased activity. The higher APA under conjoint use of organic manures and NP fertilizers over NP fertilizer alone was also observed by Srinivasan et al (2016), Jia et al (2018). The lowest APA (572.25 µgPNP/g/h) was observed in plots treated with chemical fertilizers may be attributed to less substrate availability.…”

An ongoing long-term field experiment established in 1995 at CCS Haryana Agricultural University, Hisar (India) under pearl millet-wheat cropping system was selected to examine the impact of organic manures and fertilizers on soil microbiological properties. After 19 years of experiment, the samples were collected after wheat harvest in April, 2014. Under different combinations of treatments, the microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) content in soil ranged from 202–491 and 35.0–79.8 mg/kg, respectively. The lower content of MBC and MBN was observed in farmyard manure (FYM) treated plots as compared to pressmud or poultry manure. Soil microbial quotient (SMQ) ranged from 3.18– 5.61% and higher SMQ was observed with pressmud and poultry manure application as compared to FYM application. The highest dehydrogenase activity (DHA) was reported with FYM15 (63.71 μgTPF/g/24 hr) which was statistically at par with FYM15N150 (59.75 μg TPF/g/24 h) and pressmud7.5 (58.14 μg TPF/g/24 h). Among organic manures applied alone alkaline phosphatase activity (APA) followed the order: poultry manure>FYM>pressmud. The highest urease activity (97.6 μg NH4 +-N/g/h) was observed with pressmud7.5 and this may be attributed to higher N content (3.23%) in pressmud. The dehydrogenase and urease activity decreased in the plots where organic manures were applied in conjunction with NP fertilizers as compared to solitary application of organic manures. However, reverse trend was observed in case of alkaline phosphatase. Overall, pressmud applications exhibited favorable impacts on soil properties under pearl millet wheat cropping. Therefore, continuous application of pressmud could lead to long term maintenance of soil microbial properties in these sandy loam soils.

“…As shown in our previous recorded data [ 5 ] for macro and micronutrients analysis of FW, results showed that FW is rich in N (7.01%), P (12,201 µg/g), K (1573 µg/g), Ca (89,762.5 µg/g), Mg (189 µg/g), Fe (266.81 µg/g) and Zn (94.37 µg/g). Also, the increase in onion growth attributes due to FW application could be a result of increased phosphatase and chitinase activity [ 54 ].…”

Background The increase in the human consumption of fish results in the production of organic fish wastes (FW). For enhanced soil fertility and plant growth at a lower cost and without the negative impacts of chemical fertilizers, these wastes could be employed as a valuable organic fertilizer. To determine the synergistic bio-efficacy of Trichoderma sp. and arbuscular mycorrhizal (AM) fungi in stimulating the morphological and physiological characteristics of FW-fertilized Alium cepa, as well as to investigate their involvement in boosting soil fertility, the current study was carried out. Overall, eight treatments were applied as follows: AM, Trichoderma sp., AM + Trichoderma sp., FW, AM + FW, Trichoderma sp. + FW, AM + Trichoderma sp. + FW, and control. Growth and physiological assessments of onion plants were taken after 8 weeks from FW application. Results Our results showed that FW application combined with AM fungi and Trichoderma sp. inoculations increased aggregate stability of the soil (glomalin content) and soil chitinase activity. Moreover, using the bio-inoculations along with FW amendments significantly (p < 0.05) improved the photosynthetic pigments, protein, carbohydrates, and nutrients content of onion plants. It's interesting to note that the triple interaction of AM + Trichoderma sp. + FW led to the greatest increase in plant height, root length, number of leaves, and leaf area as well as total fresh and dry weights of shoots and roots. Besides, AM fungal colonization was at its highest percentage with Trichoderma sp. inoculation, although this percentage decreased with FW addition. Conclusion We concluded that the combined treatments of AM fungi and Trichoderma sp. along with FW application to the soil can be proposed as a successful strategy for plant performance in nutrient-deficient soils as both fungal inoculants are capable of degrading these wastes and converting them into manure suitable for farming so plants can uptake the minerals effortlessly.
