This document discusses the development of a slow-release nitrogen fertilizer using hydroxyapatite nanoparticles modified with urea. Bench-scale testing showed the nanofertilizer provided slow release of nitrogen and improved phosphorus availability compared to granular urea alone. Field tests on rice crops demonstrated higher yields with the nanofertilizer when applied at 50% of the normal urea dosage. Use of such a nanofertilizer could help reduce urea losses estimated at 70% of usage in Sri Lanka, saving an estimated $44 million annually while minimizing environmental impacts.

Indian agriculture feels the pain of fatigue of green revolution.
In the past 50 years, the fertilizer consumption exponentially increased from 0.5 (1960’s) to 24 million tonnes (2013) that commensurate with four-fold increase in food grain output (254 million tonnes) In order to achieve a target of 300 million tonnes of food grains and to feed the burgeoning population of 1.4 billion in 2025, the country will require 45 million tonnes of nutrients as against a current consumption level of 23 million tonnes. The sustainable agriculture and precision farming both are the urgent issues and hence the suitable agro-technological interventions are essential (e.g., nano and biotechnology) for ensuring the safety and sustainability of relevant production system.

Polymer coated fertilizers an advance technique in nutrient management
Control release fertilizers are coated fertilizers that release nutrients over an extended period of time at a rate driven primarily by temperature and moisture of the root zone. It has been estimated that slow-release fertilizers comprise only 8-10% of the total fertilizers used in Europe, 1% in the USA and only 0.25% in the World. Dong and Wang (2007) reported that in Japan 70% of polymer coated controlled-release fertilizers are used in rice. Polymer coated fertilizers are a type of control release fertilizers, which are solid or other nutrient core, coated with various polymers. Fertilizer use efficiency can be increased by application of polymer coated fertilizer compared to common fertilizers due to very less nutrient losses. Most common three marketed products are Nutricote, Osmocote and Polyon. Pawel (2013) found that the polymer-coated fertilizers are not straight nitrogen but NPK fertilizers, particularly when containing secondary and micronutrients, the rate of release of the different nutrients, N, P, K, S, Ca, Mg and micronutrients, are generally slow, controlled-release and stabilized fertilizers not stated. Parvathi (2018) reported that customised fertilizers are multi- nutrient carriers facilitating the application of the complete range of plant nutrients in right proportion to suit the specific requirements of a crop during its stages of growth.
Nelson et al. (2012) reported that application of nitrogen @ 120 kg/ha by polymer coated urea (PCU) with non coated urea (NCU) in the ratio of 75:25(PCU:NCU) recorded the highest wheat grain yield (5370 kg/ha) and lowest with ammonium nitrate (5110 kg/ha). Dong and Wang (2007) reported that application of polymer coated nitrogen fertilizer recorded the highest Nitrogen Use Efficiency (70.54%), Nitrogen Agronomic Efficiency (32.56 kg/ha) and Nitrogen Physiological efficiency (46.16 kg/ha) compared to uncoated common fertilizers in rice crop. Prasad et al. (2012) reported that application of nano zinc fertilizers showed significantly better results in germination, shoot and root growth and Seed vigour Index over common zinc sulphate and control treatment. They also reported that application of NPK+ZnO (Nano) @2g/15 l resulted the highest plant height (43.80 cm), no. of pods per plant (16.80) and no. of filled pods per plant (15) which were significantly superior over rest of the treatments in groundnut crop.
It can be concluded that application of polymer coated fertilizers increase the Nutrient Use Efficiency (NUE), Nitrogen Agronomic Efficiency and Nitrogen Physiological efficiency, they increase the % recovery of nutrients and finally the growth and yield of crops. Nano-fertilizer certainly has the potential to improve agriculture production and they release the fertilizer slowly and extend the fertilizer effective period resulted in higher crop yields. Use of Customized Fertilizers can maximize nutrient use efficiency and ultimately improve soil fertility.

ADVANCED TECHNIQUES TO INCREASE NUTRIENT USE EFFICIENCY
ADVANCED TECHNIQUES TO INCREASE NUTRIENT USE EFFICIENCYVasantrao Nail Marathwada Krishi Vidyapeeth, Parbhani
Nutrient use efficiency (NUE) is a critically important concept in the evaluation of crop production systems. Many agricultural soils of the world are deficient in one or more of the essential nutrients to support healthy and productive plant growth. Efficiency can be defined in many ways and easily increased food production could be achieved by expanding the land area under crops and by increasing yields per unit area through intensive farming. Environmental nutrient use efficiency can be quite different than agronomic or economic efficiency and maximizing efficiency may not always be effective. Worldwide, elemental deficiencies for essential macro and micro nutrients and toxicities by Al, Mn, Fe, S, B, Cu, Mo, Cr, Cl, Na, and Si have been reported.

Establishing clear career goals enables professionals to focus their efforts on developing specific skills, gaining relevant experience, and making strategic decisions that align with their desired career trajectory. By setting both short-term and long-term objectives, individuals can systematically track their progress, make necessary adjustments, and stay motivated. Short-term goals often include acquiring new qualifications, mastering particular competencies, or securing a specific role, while long-term goals might encompass reaching executive positions, becoming industry experts, or launching entrepreneurial ventures.
Moreover, having well-defined career goals fosters a sense of purpose and direction, enhancing job satisfaction and overall productivity. It encourages continuous learning and adaptation, as professionals remain attuned to industry trends and evolving job market demands. Career goals also facilitate better time management and resource allocation, as individuals prioritize tasks and opportunities that advance their professional growth. In addition, articulating career goals can aid in networking and mentorship, as it allows individuals to communicate their aspirations clearly to potential mentors, colleagues, and employers, thereby opening doors to valuable guidance and support. Ultimately, career goals are integral to personal and professional development, driving individuals toward sustained success and fulfillment in their chosen fields.
