“…Sandy soils are the most vulnerable to the potential deteriorations of environmental conditions (e.g. erosion) due to their helpless texture (Mosa et al 2020). Soil addition of humic acid not only mended aggregate stability but also decreased the disaggregating impacts of wetting and drying cycling and structural stability of soils.…”

During 2018-2019 and 2019-2020 seasons, two-field experiments were conducted at El-Kasasin Horticultural Research Station, Ismailia Governorate, Egypt, to test the impact of potassium humate(KH) and biochar with substitution part of recommended mineral fertilization on growth parameters, physical, chemical characteristics of pods and green yield of snap bean as well as some physical and chemical soil properties after harvesting. The experiment was laid out in randomized complete block design (RCBD) with nine treatments included; solo application from 2 ton biochar+4 kg KH and 4 ton biochar+6 kg KH and each one was mixed with 25, 50 and 75% NPK from recommended dose comparing with 100% NPK. Overall, the results of this study indicated that soil addition of 75% NPK+ 4 ton biochar+6 kg KH recorded the best mean values of all tested parameters and improved growth, which reflected on yield and its components followed by 100% NPK.

“…Though, this soluble mineral N-source might be subjected to excessive losses in the investigated light textured soil (Shareef et al, 2020), but in presence of compost such loses might be limited (Bah et al, 2020). Moreover, this organic amendment is a source of soil nutrients (Abbas et al, 2011;Farid et al, 2014 andAbdelhafez et al, 2018;Elshony et al, 2019;Mosa et al, 2020;Abou Hussien et al, 2021); besides legumes solubilize insoluble soil phosphorus (Etemadi et al, 2019). This may explain why the combined "mineral+organic" nitrogen sources raised considerably NPK uptake by plants; consequently the combined treatments improved significantly the plant growth parameters and grain yield.…”

“…Because of the mycorrhizal hyphae to the plant roots, besides mobile elements as N (Grant et al, 2005), Kanwal et al (2015) suggested that colonization of wheat plants with AM fungi improved biomass, growth and essential nutrients availability. Humic is due to their high nutrient content, huge surface area, active bio-stimulants, stability against microbial decomposition and a high number of active ingredients and functional groups, (Mosa et al 2020).…”

ertilizers are a costly input but continue to make a significant contribution to the production of additional food. To maximize benefits and minimize nutrient loss from fertilizer, it must be used in the right amount, source and combination at the right time using the suitable method. The experiment was carried out during the 2018/2019 summer season in Mariout, Desert Research Center Agricultural Experiment Station, southwest of Alexandria, Egypt to study the effect of the inoculation with Mycorrhizal (MF) fungi, Humic Acid (HA) applied to soil at levels (0, 8 and 16 kg fed -1 ) and phosphorous foliar application as phosphoric acid (H 3 PO 4 72.5% P 2 O 5 ) at rates of (0, 0.75 and 1.5 ml/ l) on the yield, yield components and chemical composition of pearl millet (Pennisetumgalaucum L.). Results revealed that inoculation of pearl millet by Mycorrhizae, combined with application humic acid (16 kg/fed) and phosphoric acid (1.5ml/l) was the most effective treatment in improving fresh and dry forage yield which recorded (80.9 and 21.3 ton/fed), respectively through the whole season and recorded the highest protein content which was 24.3% for the 3 rd cut compared with other cuts. The inoculation of pearl millet by Mycorrhizae, combined with application humic acid (16 kg/fed) was the most effective treatment in improving dry matter and starch 31.1and 23.7% respectively, as the mean for three cuts. Also, this treatment recorded the highest values of nitrogen as concentration and uptake 2.65% and 184.7 kg N/fed as soon as, phosphorus concentration and uptake values 0.46% and 32.9 kg P 2 O 5 /fed respectively, as the mean for three cuts in the dry forage of pearl millet.Regarding yield, there was an increase in forage yield and nutrient uptake, especially P and Nand total antioxidants. Increasing rates of humic and phosphoric acid addition with mycorrhizae treatments increased total antioxidant activity (TAA) of leaf. TAA recorded the highest in the H 2 and P 2 with inoculation about 796, 663 and 425 (µg AAE/mg ext.) in 1 st , 2 nd and 3 rd cuts respectively.These results indicated a marked improvement in the nutrient availability status of calcareous.
