“…Various researches have reported that %N content in the dry algae biomass is significantly higher than the available organic manure (cow dung, farmyard manure etc.) [10,13,36]. The NPK content of dry algae biomass ranged from 3 to 7%, 0.5-2% and 0.4-0.8%, respectively [13,14,36,37].…”

“…The controlled growth of algae in wastewater leads to reduction of contamination load on natural resources and can also be enhance reuse efficiency. The utilization of algae in the treatment of different waste such as agro-based industrial wastes, sewage, industrial wastes (metal finishing, paper, and textile) and even landfill leachate [10,[12][13][14][15]. Waste mitigation potential of an algal species entirely depends on the algal productivity, nutrient and pollutant removal efficiency, and cost of biomass harvest [16][17][18].…”

“…The algal biomass after remediation of wastewater having vast potential as biofertilizer. The N,P and K content in microalgae algae biomass varies from 7 to 9%, 1-2% and 0.1-1%, respectively [5,13]. The algal biomass can also be used as biofertilizer in agro-ecosystems.…”

“…The algal biomass can also be used as biofertilizer in agro-ecosystems. The algal biomass not only provides essential nutrients to the agricultural crops but also significantly contribute to improve the soil carbon and soil fertility [5,13]. Sharma et al [5] in a study conducted on the impact of algae biomass as manure on the nitrate leaching reported that microalgal manure are slow releasing in nature and less leaching of nitrate as compared to chemical fertilizer was observed, so application of microalgae biomass also results in reduction of nitrate leaching from agricultural fields as compared to chemical fertilizer, hence prevent eutrophication of the water bodies.…”

In the recent years, due to heavy surge in the price of petrochemical products, researchers are getting interest towards renewable bioenergy resources such as algal-based biomass. In order to meet a world energy demand, current bioeconomy challenges and to produce valuable products, intensive and integrated research on algal biorefinery is highly required. Even though several research carried out study for the conversion of algae biomass to biofuel, but none of these proved economically viable. Hence, range of value added product (biodiesel, biochar, fertilizer, etc.) must be produced subsequently from algae. The utilization of microalgae for biomass production is better than agricultural crops as microalgae do not required fresh water for its growth, it can readily grow on wastewater throughout the year. Generation of wastewater is severe concern throughout the world and discharge of wastewater without proper treatment in to water bodies causes water pollution. Microalgae bear vast potential in significantly deescalating pollutant load (nitrate, TDS, ammonium, phosphate, organic load) from wastewater. The harvested algal biomass after remediation has significance role in producing biofuels and by-products in a sustainable way. In this chapter, emphasis would be given on role of algae in wastewater treatment and its biorefinary approach for sustainable energy development.

“…Soil health improvement is pre-requisite for sustaining soil health and crop productivity. Agricultural management practices can reduce delivery of normal ecosystem services and functions, for instance by intensive use of chemical fertilizers and pesticides can increase nutrient losses, polluting water bodies (eutrophication) and aquatic organisms [6]. This could incur additional cost on water purification, decrease the esthetic and recreational values of water reservoirs.…”

Oilseed Crops - Uses, Biology and Production

Oilseed crops are major part of human diet providing energy, used for cosmetics, health supplements and other purposes. Intensive agricultural practices, overexploitation of natural resource and climate change pattern have adverse impact on soil health, thus becoming serious concern for oilseed crop production and livelihood security of farmers. Maintenance of soil health with amendments can restore, revitalize and regain the soil quality for sustainable agriculture. Soil amendments, therefore have definite advantage by improving soil health and facilitating nutrient supply to oilseed crops. Soil organic amendments such as animal manure, compost, vermicompost, biosolids/sewage sludge, biochar etc. and inorganic amendments such as gypsum, zeolite, pyrite etc. are the most commonly available amendments which can be directly applied to soil after treatments. Direct and indirect effect of soil amendments on soil chemical, physical and biological properties significantly influences soil-plant-continuum, beneficial for soil health improvement, carbon sequestration and oilseed yield improvement. Soil organic amendments could substitute nearly 25–50% of synthetic fertilizers, enhance nutrient use efficiency and influencing oilseed yield response. Soil amendments may sustain or increase oilseed productivity at reduced production and environmental cost, thus, improve soil health and water use efficiency and its quality, and mitigating climate change impact.
