“…One of the greatest challenges nowadays in crop production is to maintain soil fertility to ensure the production of an appropriate amount of feed and food raw materials of good quality. Natural and ecological conditions (climate, climate change, soil formation, parent material) are less controllable factors for farming, but agrotechnical processes (nutrient supply, use of chemicals) can be professionally selected for more successful productivity (SÁNDOR, 2006). Experiments older than 20 years can be termed long-term experiments (RASMUSSEN et al, 1998) studying crop production, nutrient cycling, and the environmental effects of agriculture.…”

The Westsik’s long-term crop rotation experiment was set up in 1929 at the Nyíregyháza Experimental Station (NE Hungary) on a slightly acidic Arenosol. Besides fallow crop rotation (CR), effects of different organic amendments (lupine as green manure, lupine as main crop, straw manure, and farmyard manure (FYM) were studied with or without N or NPK-fertilizers. The crop rotation consisted of rye, potato, lupine, and oat with common vetch. The soil of potato plots was analysed in 2019 at the 90th anniversary of Westsik’s crop rotation experiment.The following chemical and microbiological soil parameters were determined: soil pH, available nutrient contents, organic carbon (OC) and nitrogen (ON) contents, microbial biomass carbon (MBC) and nitrogen (MBN), soil respiration, net nitrification, and activity of some soil enzymes.In the CRs, the soil pHH2O varied from acidic to weakly alkaline and it largely differed from pHKCl. The results showed a significant increase in the content of nitrate, available phosphorus and potassium in most of the fertilized plots. Applying straw, green manure, or FYM significantly increased the OC and ON contents. The total count of cultivable bacteria increased upon the application of the organic manures. Combined application of straw manure and N-fertilization heavily improved the abundance of the microscopic fungi.While all the applied organic manures significantly enhanced the MBC, the MBN increased only by the green manure amendment. Our results revealed higher soil respiration rate in the plots receiving straw or FYM than in the control. Both green manure and FYM elevated the net nitrification rate. Phosphatase, saccharase, urease, and dehydrogenase enzymes showed a hesitating response to the manure application in the different CRs.The soil respiration and dehydrogenase activity correlated to most of the measured chemical parameters. Among microbiological properties, the MBC and MBN, as well as dehydrogenase and other enzyme activities displayed a positive correlation. Results proved the need for the exogenous application of organic matter in the form of organic manures to enhance the nutritional status and health of the soil.

“…The soil environment is one of the factors that may influence the onset of fruit production, productivity and the synthesis of active compounds such as azadirachtin 3, 4. However, agricultural practices such as fertilisation and use of chemical products affect soil properties, in turn affecting the microbial activity in this environment 5…”

A field trial was conducted to investigate the ‘Phytotoxicity of pendimethalin on the emergence of seedlings in direct seeded rice (DSR) across different concentrations’ during the Kharif season of 2022 at the experimental farm of the School of Agriculture, Lovely Professional University, Phagwara, Punjab. The experiment was conducted using a randomized block design with five treatments using different doses of pendimethalin (1600, 1800, 2000, and 2200 gram active ingredient per hectare (g ai per ha), and control (untreated)). Application of pendimethalin at 1600 g ai per ha resulted in a significantly higher number of seedlings than other treatment groups. The lowest number of seedlings was observed in the 2200 g ai per ha treatment group. The number of microbes present was optimal during the treatment with 1600 g ai per ha pendimethalin. With an increase in the dosage of pendimethalin, a decrease in the count of soil microbes was observed, with the lowest microbial count observed with the highest dose of pendimethalin, i.e., 2200 g ai per ha. No phytotoxic effect was observed in the DSR treated with pendimethalin at 1600 g ai per ha. Therefore the present study has to be obtain the appropriate use of dosage to inhibit the toxicity of herbicide as well as maintain the soil fertility and microbial growth.
