There are many “Save the Soil” movements highlighting the degradation of the soil due to excessive use of fertilizers, ground water contamination and environmental pollution. An alternative strategy is the use of humic acids from Organic Matter (OM) in soils. Humic acids help grow better vegetables, quality fruits like (peas, potatoes, tomatoes, pomegranates, mangoes), cereals, and pulses. These create supramolecular self– assemblies capable of retaining water and not allowing loss of minerals and ions. Humic acids isolated from soil, lignite and city solid waste are emerging as attractive sources for developing value added products from them. There is much interest in exploiting the commercial aspects in the energy sector of the economy as these new technologies could help in cleaning the environment as well. In this paper, the isolation of a new humic acid from the soil of Gwal Pahari, Gurgaon, Haryana, India is described. This water soluble, Ninhydrin positive Gwal Pahari Acid (GPA) contains thirteen chiral centers and contains both partly rigid and dynamic systems capable of exhibiting pseudo rotation. The proposed structure of this new humic acid is based on spectroscopic studies (e.g. FT-IR, UV-visible spectroscopy), detailed mass spectrometry, and very challenging 1H- NMR and 2D-NMR studies. Ion leakage studies on Arabidopsis thaliana have shown that the new compound provides protection to the plant, and greenhouse studies demonstrate that Gwal Pahari Acid brings about substantial growth in the tomato plant.

“…Potassium, phosphorus, calcium, sodium, magnesium, iron, copper, zinc, and manganese are abundant in chickpeas, supporting bone health, nerve function, immune system, and overall well-being [48]. Selenium, a trace element present in chickpeas, holds nutritional signifcance for human health [49]. Vitamins, another crucial component of chickpeas, encompass vitamin C, ribofavin, thiamine, and retinol.…”

Chickpea is a globally cultivated legume, rich in vitamins, protein, carbohydrates, polyphenols, fatty acids, fibers, and flavonoids. Despite its nutritional benefits, chickpeas contain antinutritional factors that can hinder nutrient absorption. Therefore, we reviewed the various pretreatment methods to enhance chickpea protein’s nutritional value and functional properties. Thermal and biochemical treatments and food applications of chickpea protein are thoroughly reviewed. The review revealed that the physical, thermal, and biochemical treatments were reported to be effective in reducing antinutritional factors and improving protein solubility, emulsifying capacity, and foaming properties. Chickpea proteins were used in cereals and bakery products to meet consumer demand. Encapsulation of chickpea protein enhances nutrient stability, and its inclusion in gluten-free products has different effects on the glycemic index, antioxidant activity, and overall acceptability. These findings highlight chickpea’s potential to improve the nutritional and functional aspects of food products while offering health benefits to consumers.

In recent years, the simple synthesis of artificial humic substances (A-HS) by alkaline hydrothermal processing of waste biomass was described. This A-HS was shown to support water and mineral binding, to change soil structure, to avoid fertilizer mineralization, and to support plant growth. Many of the observed macroscopic effects could, however, not be directly related to the minute amounts of A-HS which have been added, and an A-HS stimulated microbiome was found to be the key for understanding. In this review, we describe such anthropogenic soil in the language of the modern concept of living engineered materials and identify natural and artificial HS as the enabler to set up the interactive microbial system along the interfaces of the mineral grains. In that, old chemical concepts as surface activity, redox mediation, and pH buffering are the base of the system structure build-up and the complex self-adaptability of biological systems. The resulting chemical/biological hybrid system has the potential to address world problems as soil fertility, nutrition of a growing world population, and climate change. CONTENTS
