“…1). These results agree with the findings of Farid et al (2021b) who found that the combined use of organic and mineral fertilizers could effectively improve plant growth and productivity versus even 100% mineral fertilizers. Although, the organic additive (biogas) supply plants with nutrients at relatively slower rates versus mineral fertilizers; yet it lessen their fixation in soil via forming soluble complexes (Abbas et al 2020;Hussein et al 2022).…”

“…Even the relatively resistant biodegradable organic components, named humic substances (El-Shwarby et al 2022) can be used sucessfully to increase crop production. These organics form soluble complexes with soil nutrients which, in turn, increases nutrient uptake by plants and consequently boost their growth and productivity (Farid et al, 2021b).…”

XPONENTIAL population growth and soaring fertilizer prices are among the main challenges threating food security worldwide. Probably, substituting chemical inputs (partially or completely) with organic and/or bio-alternatives are the keys to achieve sustainable development. Thus, a field experiment was conducted for two successive seasons in a randomized block design to achieve this goal, comprising the following treatments: 100% mineral P and K fertilizers (T 1 , control), 10 g potassium humate (KH) kg -1 (T 2 ), 10 g humic acid (HA) kg -1 (T 3 ) and 10 g kg -1 fulvic acid (FA) (T 4 ). For treatments from T 2 to T 4 , supplementary doses of chemical fertilizers were added to satisfy wheat needs for P and K. Also, a combined treatment of 50% biogas (added on nitrogen bases) plus supplementary PK doses in the form of (i) rock phosphate and feldspars + biofertilizers (Bacillus megatherium and Bacillus circulans) (T 5 ) or (ii) chemical P and K fertilizers were included (T 6 ). All plots were planted with wheat and received 20% of the recommended N requirements via N 2 -fixation with Bacillus polymyxa while the other 80% was accomplished as ammonium nitrate (after considering the added N in organic additives). Key findings indicate that application of biogas+ supplementary chemical PK fertilizers (T 6 ) recorded the highest increases in P and K available contents in soil. This in turn significantly raised their concentrations within different plant parts and boosted straw and grain yields during the two seasons of study. Application of 100% mineral PK (T 1 ) recorded significantly lower values in all abovementioned parameters versus T 6 . Nevertheless, these two treatments (T 1 and T 6 ) recorded comparable increases in 1000-grain weight, plant height, spike lengths and number of grains per spike. Application of KH, HA and FA as partial substitutes for chemical fertilizers (T 2 -T 4 ) lessened significantly nutrient bioavailability and their contents within wheat parts; as a result, plant growth and yield components declined significantly. The least values were recorded for the treatment that received biogas+ rock phosphate and feldspar + biofertilizers (T 5 ). Overall, straw and grain yields of wheat plants were correlated significantly with P and K contents in both shoots and grains. In conclusion, the combination between biogas and chemical fertilizers seemed to be the optimum selection to satisfy wheat needs for nutrients; hence increase wheat productivity under arid conditions.

“…Integrated management of K-additives (apply Amphora extract of algae, biochar, and compost) to improve Zucchini productivity grown on sandy soil [43]. The combined amending sandy soils with mixed organic and mineral as N-sources and irradiating seeds of faba bean to increase the crop productivity was reported by Farid et al [44]. The microbial mixtures (Bacillus subtilis, Pseudomonas flourescens, Pleurotus ostreatus, and mycorrhizeen ® ) modified soil physio-chemical properties and its fertility, and consequently increased productivity of Hibiscus sabdariffa L. in sandy soil [45].…”

Soil is a real treasure that humans cannot live without. Therefore, it is very important to sustain and conserve soils to guarantee food, fiber, fuel, and other human necessities. Healthy or high-quality soils that include adequate fertility, diverse ecosystems, and good physical properties are important to allow soil to produce healthy food in support of human health. When a soil suffers from degradation, the soil’s productivity decreases. Soil restoration refers to the reversal of degradational processes. This study is a pictorial review on the nano-restoration of soil to return its fertility. Restoring soil fertility for zero hunger and restoration of degraded soils are also discussed. Sustainable production of nanoparticles using plants and microbes is part of the process of soil nano-restoration. The nexus of nanoparticle–plant–microbe (NPM) is a crucial issue for soil fertility. This nexus itself has several internal interactions or relationships, which control the bioavailability of nutrients, agrochemicals, or pollutants for cultivated plants. The NPM nexus is also controlled by many factors that are related to soil fertility and its restoration. This is the first photographic review on nano-restoration to return and sustain soil fertility. However, several additional open questions need to be answered and will be discussed in this work.

“…Its seeds are the edible parts that may partially replace meat and dairy products in the human diet [3] because they are rich in complex carbohydrates, proteins, dietary fiber and several bioactive compounds [4]. This crop can be grown successfully on poor light-textured soils [5]; yet these soils need major improvements to raise their productivity [6,7]. Accordingly, organic applications are guaranteed to attain these aims [8].…”

Organic Materials and Their Chemically Extracted Humic and Fulvic Acids as Potential Soil Amendments for Faba Bean Cultivation in Soils with Varying CaCO3 Contents

Organic amendments are important sources of nutrients that release upon organic matter degradation, yet the stability of these organics in arid and semi-arid regions is relatively low. In contrast, humic substances (HS) are resistant to biodegradation and can keep nutrients in the soil available for the plant over a long time. Combinations between humic substances (HS) and mineral-N fertilizers are assumed to retain higher available nutrients in soils than those recorded for the sole application of either mineral or organic applications. We anticipate, however, that humic substances might not be as efficient as the organics from which they were extracted in increasing NP uptake by plants. To test these assumptions, faba bean was planted in a pot experiment under greenhouse conditions following a complete randomized design while considering three factors: two soils (calcareous and non-calcareous, Factor A), two organics (biogas and compost, Factor B) and combinations of the organics and their extracts (HA or FA) together with complementary doses of mineral-N ((NH4)2SO4) to attain a total rate of 50 kg N ha−1 (the recommended dose for faba bean plants) (Factor C). Results indicated that nitrogenase activity increased significantly due to the application of the used organics. In this respect, compost manure caused higher nitrogenase activity than biogas manure did. Humic substances raised NP-availability and the uptake by plants significantly; however, the values of increase were lower than those that occurred due to the compost or biogas manure. Moreover, the sole application of the used organics recorded the highest increases in plant biomass. Significant correlations were also detected between NP-availability, uptake and plant biomass. This means that HS could probably retain nutrients in available forms for long time periods, yet nutrients released continuously but slowly upon decomposition of organics seemed more important for plant nutrition.
