Nutrient Management Technologies and the Role of Organic Matrix-Based Slow-Release Biofertilizers for Agricultural Sustainability: A Review

Abstract

Natural soil containing nutrients (like nitrogen, phosphorus, calcium and potassium) allows plants to grow. The deficiency of nutrients in soil reduced the growth and development of plants. When the nutrient level is too low, the plant cannot function properly and then fertilizers provide sufficient nutrients to plants. Nowadays the farmer applied various kinds of synthetic and organic and some special class of microbial fertilizers for more production of agricultural crops. Excess use of chemical fertilizers caused nutrient leaching problems and also pollutes soil, water and air environment. However, chemical fertilizers are expensive, non-eco-friendly, cause eutrophication, reduce organic matter and microbial activity in the soil and are hazardous to health. Therefore, Slow-release biofertilizers are also produced by the technical intermediations that breakdown the nutrients and make them available to the plants for a longer duration. These fertilizers play an important role in improving the growth and development of plants, thereby mitigating environmental pollution and helping in sustainable agriculture. The efficacy of slow-release biofertilizers can be enhanced plant growth and productivity and manage the nutrient leaching from soil and also control water pollution.

Inorganic Phosphate Solubilization by a Novel Isolated Bacterial Strain Enterobacter sp. ITCB-09 and Its Application Potential as Biofertilizer

“…A biofertilizer can be composed of a range of microorganisms, each with a specific role, from promoting plant growth by providing different nutrients to protect against pathogens [15]. Among the main bacterial genera that have reported biofertilizer potential are Rhizobium, Azotobacter, Azospirillum, Pseudomonas, Bacillus, Enterobacter, Klebsiella, Variovorax, and Serratia [16][17][18].…”

Effects of soil ameliorant composition on soil properties and chili (Capsicum annuum L.) yield in inceptisols Jatinangor

“…Application of soil ameliorant could improve the biological poperties of soil (Basu et al, 2017). the addition of dolomite and guano has not given a significant effect because the nature of giving organic matter on the soil takes a long time, The response of plants to organic fertilizer is slower, because organic fertilizer is slow release (Chaudhary et al, 2020). Biochar and organic matter can improve soil quality by converting agricultural waste into soil enhancers that store carbon and make the soil more fertile, applying biochar to agricultural land can increase P, K content, microbial activity, and soil quality and cannhelp reduce nitrogen leaching into water soil and reduce fertilizer costs (Situmeang, 2018).…”

Regenerative agriculture and integrative permaculture for sustainable and technology driven global food production and security

“… Slow release biofertilizers, produced by encapsulation technology, can breakdown nutrients and make them available to plants for longer durations, thus enhancing plant growth and productivity while mitigating environmental pollution, and nutrient leaching (Chen et al, 2014;Ju et al, 2009).  Phi based farming system, as an emerging novel strategy in modern agriculture can potentially minimize the algal blooms in lakes and reservoirs generated from phosphorus fertilizers application in agricultural fields (Chaudhary et al, 2020).…”

“… Slow release biofertilizers, produced by encapsulation technology, can breakdown nutrients and make them available to plants for longer durations, thus enhancing plant growth and productivity while mitigating environmental pollution and nutrient leaching (Chen et al., 2014; Ju et al., 2009). Phi‐based farming system, as an emerging novel strategy in modern agriculture can potentially minimize the algal blooms in lakes and reservoirs generated from P fertilizers application in agricultural fields (Chaudhary et al., 2020). Conservation agriculture (CA) is based on reduced tillage, maintaining crop residues as soil cover, and crop rotation and is highly promoted for sustainable soil management practiced in North and South America (Hobbs et al., 2008; Kassam et al., 2009).…”
