“…These results are in agreement with those of [14].The results of the same table indicated that inoculation with Bacillus subtilis led to treatment (B1) significantly excelled with an average of (11.006) mg. kg -1 is higher than the control treatment (B0), which reached (8.760) mg. kg -1 The reason for this is due to the bacteria secreting organic acids that lower the pH of the soil, causing the dissolution of phosphate compounds, including phosphate rock, which in turn releases phosphorous [15]. The reason for this increase is the secretions of acidic radicals and the activity of microorganisms through the secretion of organic acids that dissolve phosphate minerals and in chelating the positive ions present with the phosphorous ion directly, which leads to the release of phosphorus into the solution [16,17]. These results agree with What [15] found .In addition the same table indicates that the bi-interaction between Azotobacter bacteria and Bacillus subtilis led to a significant increase in the soil phosphorous concentration of the treatment (A1B1) by (12.033) mg. kg -1 is higher than the control treatment (A0B0), which was (8.206) mg. kg -1 .…”

A field experiment was conducted during the agricultural season 2021-2022 with an agricultural area in Al-Nouriah area / Al-Shafi’i district of Al-Diwaniyah Province. Two levels of Azotobacter (A1, A0) inoculation and non-inoculation, as well as the use of two levels of Bacillus subtilis (B1, B0) inoculation and non-inoculation, and four levels of phosphate rock fertilizer (P0, P1, P2, P3) were used. ) kg.h-1 and the interaction between them In addition to the concentration of phosphorous in soil and plants and the numerical density of Azotobacter and Bacillus. A factorial experiment was applied. according to a randomized complete block design (RCBD) with three replications. The results of the statistical analysis showed the least significant difference L.S.D. The interaction treatment (Azotobacter inoculation + Bacillus inoculation + rock phosphate fertilizer) Compared with the control treatment by giving it the highest mean of (phosphorous concentration in soil and plants, number of Azotobacter and number of Bacillus bacteria) amounted to (13.647) mg.kg-1 and (3379) mg.kg-1 and (10.54) CFU/gm Soil x 10-6 and (7.08) CFU/gm Soil x 10-6 respectively.

Anthropogenic activities have resulted in land desertification in various regions of the world, leading to the degradation of critical soil characteristics such as organic matter (OM) content, nutrient stock, and prevailing biodiversity. Restoring such degraded soils through organic matter amendments and diversified crop rotations is thus an intrinsic part of organic farming. This review discusses a wide range of organic farming impacts on soil health and crop productivity by focusing on organic fertilizers and crop diversification. Conventional fertilizers were considered vital for agricultural production to harvest high crop yields. Nevertheless, they are now deemed as environmentally hazardous and an obstacle to sustainable agroecosystems due to intensive chemical inputs that damage the soil over time and have long-lasting impacts. Conventional fertilization results in nutrient depletion, loss of microbial diversity, organic matter reduction, and deterioration of physical characteristics of the soil. Conversely, organic fertilization makes use of naturally existing resources to improve soil health. Organic amendments such as biochar, manure, and fermented grass improve soil’s physical, chemical, and biological properties and promote the growth and diversity of beneficial soil microorganisms—important in nutrient cycling and soil stability. They facilitate the uptake of nutrients, hinder crop pathogen growth, mitigate heavy metals, and decompose xenobiotic organic substances. Moreover, growing cover crops is also a major strategy to improve soil health. Diversified crop rotation with combinatorial use of organic fertilizers may improve soil health and agricultural yields without any detrimental impacts on the environment and soil, ensuring sustainable food production, safety, and security. This integrated approach contributes to minimizing the use of chemical fertilizers and their effects on environmental health. It also contributes to reducing agricultural inputs along with enhancing OM, soil microbial diversity and biomass, nitrogen fixation, and carbon sequestration. Therefore, cover crops and organic fertilization may offer sustainable agroecosystems and climate change mitigation.
