“…However, the use of some mixtures requires care, as there may be a deficiency of nutrients for the plants due to the unavailability of some elements (Bunt, 1976). These nutrients must be supplied to the plant as a form of fertilization (El-Ramady et al, 2020). In this way, the commercial substrate is free of fertilizer when purchased, and the producer should add the nutrient of interest.…”

Environmental conservation and regeneration actions must consider plant species that add value by restoring structural and functional aspects of the ecosystem. The forest species, Peltophorum dubium, has several characteristics that make its use viable in projects of restoration of degraded areas, making it necessary to study the species' responses to different cultivation environments. Thus, 500 seeds were selected and sown in vermicompost substrates prepared with different proportions of cattle rumen content (CR) and sugarcane bagasse (SB) (V1 - 60% CR x 40% SB / V2 - 50% CR x 50 % SB / V3 - 40% CR x 60% SB / V4 - 70% CR x 30% SB) and in an commercial substrate (Plantmax®). At 79 days after sowing, 20 seedlings per treatment were removed; they were weighed and measured, resulting in growth, dry matter, and vigor data. The vermicompost substrates were sent to the chemical analysis laboratory to determine their chemical composition. The data were submitted to normality analysis. Analysis of variance was performed for normal data and the Kruskal Wallis test for data that did not show normality. The means or medians were compared using the Tukey test at a 5% probability level. Based on the results related to the growth and vigor of P. dubium seedlings, it is possible to state that the productive potential of the species was higher in the vermicompost substrates.

“…The above results confirm the assumption of the study which indicates that plants fed on Zn as foliar spray increase significantly P-contents within their tissues.The efficiency of Zn-fertilizers could be arranged as follows: ZnO-NP> Zn-EDTA> ZnSO 4. Generally, nano-fertilizers are efficient fertilizers to satisfy plant needs for nutirnets (Abdalla et al, 2018;El-Ghamry et al, 2018;Omara et al, 2019;Shams and Abbas, 2019;El-Ramady et al, 2020). Although, P-content within maize shoots varied slightly; however, insignificantly owing to the application of different Zn-sources.…”

A PPLYING Zn as soil fertilizers might undergo precipitation in presence of phosphate fertilizers; alternatively, this nutrient may be amended through foliar application. Specifically, we hypothesized that the effect of Zn foliar application is quite enough to overcome Zn deficiency beside its synergetic effect on P uptake. To test this hypothesis, a field study was conducted in a split-plot design where Zn-sources, i.e. ZnSO 4 , Zn-EDTA and ZnO-nano-particles (ZnO-NP) were plotted in main plots while their rates of application (0, 5, 10 and 15 mg L -1 ) were schemed in sub-plots. Results obtained herein indicate that these three fertilizers not only improved significantly concentrations of both P and Zn in maize during V14-fouteenth leaf and physiological maturity growth stages but also increased significantly the available contents of these nutrients in soil, especially with increasing the level of foliar application. Moreover, these fertilizers improved significantly plant height during the abovementioned growth stages and raised grain yield and 100-grain weight. The efficiency of these fertilizers could be arranged as follows: ZnO-NP> Zn-EDTA> ZnSO 4 . In conclusion, Zn foliar application especially in the nano form recorded a synergic effect on P availability and uptake; consequently these applications increased maize production as just mentioned with superiority for ZnO-NP; however, further studies are needed to investigate the residual effects of these nano-particles within the edible plant parts.

“…Unfortunately, Egyptian old agricultural soils are decreasing due to urban sprawl and degradation (Enar et al, 2021). Soil is the medium which provides plants with necessary nutrients needed for growth (El-Ramady et al, 2020). The real treasure for agriculture, human and environment is found in soil.…”

ourteen soil profiles were collected to represent an area about 40 feddans of faculty of agriculture farm, Sohag University to evaluate land capability and crop suitability of soils. Morphological, physical, chemical, fertility characteristics of examined soils were recognized using standard methods of soil testing. All soil attributes were input in different models of suitability and capability evaluation. The salient findings of this study revealed that, the study area was near to optimal (G1) and good capable (G2) except few sites were very poor (G4). Soil suitability evaluation was done for Wheat, Maize, Alfalfa and Poato crops using parametric and MicroLEIS (ALMAGRA) models. The area under investigation has been generally divided into highly to marginally suitable (S1 and S2 in parametric method and S3 in MicroLEIS-ALMAGRA model) for cultivating these crops except few sites were not suitable (S5 in MicroLEIS model) for this purpose. Soil limitations were observed in the study area such as low organic matter, coarse soil texture, alkalinity, and salinity. Storie index and parametric methods were strongly recommended to be used for land capability and suitability assessment in the investigated area, respectively. These findings are useful for decision makers to be used in better planning and management of agricultural lands.
