Abstract. Soil structure is sensitive to intensive soil management. It can be ameliorated by a reduction in cultivation and stimulation of plant microbial mediators for aggregate formation, latter prerequisite measure quality. Cover crops (CC) are part an integrated approach stabilize or improve Thereby, the incorporation diverse CC mixtures hypothesized increase positive effects applications. This study entailed investigation legacy effect on aggregates after three crop rotations second main (winter wheat) last treatment. Four CCs (mustard, phacelia, clover, oat) cultivated pure stands fallow treatment were compared mixture four species (Mix4) highly 12 (Mix12) long-term field experiment Germany. The organic carbon (OC) distribution within macroaggregate fractions (16–8, 8–4, 4–2, 2–1 < 1 mm) their stability measured dry wet sieving methods, mean weight diameter (MWD) was calculated from water-stable aggregates. results showed that fallow, all increased MWD between 10 19 % under following crop. average over slightly higher (16 %) than single (12 %).

Through a variety of mechanisms, including increasing the amount readily available mineral nutrients, regulating phytohormone levels, and biocontrol phytopathogens, plant growth-promoting rhizobacteria (PGPR) associated with rhizosphere either directly or indirectly stimulates growth development. The establishment, survival, persistence PGPR inoculants are widely acknowledged to be contingent upon these two parameters, in addition intricate network interactions within rhizosphere. In general, soil is moist environment significant amounts carbon that have been degraded harbors large population microbes. rhizo-microbiome crucial agriculture because wide root exudates cell debris attract unique distinct patterns microbial colonization. plays role manufacture regulation extracellular molecules, hormones, secondary metabolites, antibiotics, various signaling chemicals.

Abstract Crop suitability analysis plays an important role in identifying and utilizing the areas suitable for better crop growth higher yield without deteriorating natural resources. The present study aimed to identify rice coconut cultivation across coastal region of India using analytic hierarchy process (AHP) integrated with geographic information systems (GIS) remote sensing. A total nine parameters were selected including elevation, slope, soil depth, drainage, texture, pH, organic carbon, rainfall, temperature a land use cover (LULC) constraint map. This represents first-ever application approach combining AHP, GIS, sensing entire India. weights subclasses assigned AHP method based on experts’ opinions. Subsequently, all thematic maps overlaid weighted overlay generate Separately, LULC mask map was used extract create crop-specific maps. final classified into four different classes: highly suitable, moderately marginally not production. findings revealed that approximately 13.68% area around 19.26% 18.35% being respectively, 13.76% cultivation. Similarly, cultivation, 11% 27.40% 18.34% suitable. However, about 35% deemed permanently unsuitable any type validated under receiver operating characteristic curve (AUROC).

Abstract The inoculation of microbes into soil environments has numerous applications for improving quality and crop health; however, the ability exogenous engineered to survive spread in remains uncertain. To address this challenge, we assayed survival Mycobacterium smegmatis , with either plasmid transformation or genome integration, as well its mycobacteriophage Kampy, both sterilized non-sterilized microcosms over a period 49 days. While M. Kampy persisted all microcosms, there was minimal evidence 5 cm away from site. There higher prevalence observed than soil, suggesting detrimental effect native biotic viral community on phage proliferate microcosm.
