  Introduction: Chemical fertilizers are one of the most important factors that pollute the environment. Chemical fertilizers can cause air, soil, surface and underground water pollution and cause irreparable damage to the environment. Among the chemical fertilizers, nitrogenous fertilizers have the largest amount of consumption and can be affected by the oxidation and reduction process and affect the environment the most. So far, many methods have been presented to recommend chemical fertilizers, but all these methods are qualitative and cannot calculate the quantity of fertilizer required by the plant. The Integrated Plant and Soil System (IPSS) was first described in 2019. In this method, the amount of elements needed by plants is calculated quantitatively. Materials and Methods: There was a significant correlation between nitrogen of saturated soil extract and nitrogen of plant organs, and the highest correlation was observed between the nitrogen of young leaves and the nitrogen of saturated soil extract. Also, the highest correlation was between the nitrogen of young leaves and other plant organs. Organs of plants whose nitrogen had a significant correlation with soil nitrogen were selected and multivariate regression equations were determined between them and soil saturated extract nitrogen. By simplifying them, two equations with two variables were obtained, according to which the required fertilizer can be calculated. Results and Discussion: There was a significant correlation between nitrogen of saturated soil extract and nitrogen of plant organs, and the highest correlation was observed between the nitrogen of young leaves and the nitrogen of saturated soil extract. Also, the highest correlation was between the nitrogen of young leaves and other plant organs. Organs of plants whose nitrogen had a significant correlation with soil nitrogen were selected and multivariate regression equations were determined between them and soil saturated extract nitrogen. By simplifying them, two equations with two variables were obtained, according to which the required fertilizer can be calculated. Conclusion: The results of this research are two bivariate regression equations, based on which the amount of fertilizer required by plants can be calculated quantitatively and accurately, and the environment can be protected from the risk of chemical fertilizer contamination. This method can be used for all elements and plants in hydroponic and soil cultivation systems. Manuscript profile

  Corn (maize) is cultivated in several parts of irrigation lands of Iran and over application of chemical fertilizers causing environmental and human health impacts. However, soil nutrients available analysis can be improved with optimal chemical fertilizer consumption in these farms. The objective of this research was to evaluate soil nutrients content and appropriate fertilizers application in the corn farms which was conducted in Kuzaran, west Kermanshah, Iran. Soil sampling carried out from 0-30 soil depth and subjected to soil organic carbon (SOC) content as well as availability of N, P, K, Mn, Fe and Zn analysis. The results showed that the mean SOC was low (1.23%) and significantly (p<0.05) correlated to all measured soil nutrients. The respective average level of N, P, K, Mn, Fe and Zn was 0.121, 17.00, 381, 9.71, 12.41 and0.86 mg-1 kg. The recommended consumption rates included triple super phosphate, potassium sulfate and iron, hence; these rates were not correlated with P, K and F available in the soil. Furthermore, recommended potassium sulfate input was 134 kg/ha, while soil K available was sufficient for corn crop. In contrasts, the recommended levels of Urea (418 kg/ha), manganese sulfate (32.4 kg/ha) and Zinc sulfate (54.3 kg/ha) were significantly correlated with soil N, Mn and Zn content. Thus, recommended chemical fertilizers application was not sufficiently accurate and did not follow by soil nutrients content.  For sustaining environment and human health, the consumption of chemical fertilizer particularly in corn farms should be recommended based on soil nutrient analysis and crop needs.

  The purpose of this study was to evaluate the effect of bacterial chemical integrated feeding system on yield and yield components of wheat phonological growth stages. Treatments included: Two levels of bio fertilizers B1: Seed inoculation with bio fertilizer, B2: Sterile inoculated seed, three levels of N fertilizer N1: Nitrogen fertilizer application 20% less than recommended, N2: Nitrogen fertilizer equal to recommended, N3: Nitrogen fertilizer application was 20% more than recommended in 4 replications in a completely randomized block design. The results showed that using B2N2 treatment, grain yield was 16.14% and 16.36% higher than B2N1 and B2N3, respectively. By applying B2N2 treatment, 1000-grain weight was higher than B2N1 and B2N3 as 11.05% and 6.92%, respectively. Grain yield was increased with simple nitrogen fertilizer treatment by fertilizer application 20% less than recommended at 12.20% and by application of fertilizer by 20% higher than recommended by 16.67% which was significant. The effect of bio fertilizer and nitrogen fertilizer treatments on bio farm inoculation and nitrogen application on sterile inoculation was quite noticeable. Therefore, bio farm fertilizer application and nitrogen fertilizer application are based on fertilizer recommendation to improve yield of wheat and its components. This highlights the importance of the bacterial chemical fusion system at different stages of wheat growth. Manuscript profile
