“…19 Mesmo que se considere um padrão de uso mais eficiente de fertilizantes em países industrializados, 21 a demanda pelo fósforo aumenta com a necessidade de produção agrícola que, por sua vez, é incrementada com a mudança de padrões de consumo, onde a previsão é de que até 2050 ocorra um aumento de 70% a 100% na demanda de fósforo dos países emergentes, 22 até mesmo por suas receitas econômicas serem oriundas da exportação por parte do setor agrícola, como por exemplo de soja e arroz. [24][25][26] O problema da eutrofização de corpos hídricos O problema do P enquanto material residual começou a ser estudado por conta da poluição hídrica que o elemento pode causar. As resoluções CONAMA N° 357/2005 e N° 430/2011, definem os parâmetros de qualidade para efluentes lançados em corpos d'água.…”

SUSTAINABILITY IN PHOSPHORUS USE: A BIBLIOGRAPHIC REVIEW FOCUSING ON THE CURRENT SITUATION IN THE STATE OF SÃO PAULO, BRAZIL. Phosphorus is a non-renewable element essential for the existence of life and also for food security. This resource has the property of limiting plant growth, becoming a fundamental part of agricultural production. On the other hand, when this element is present in high concentrations in aquatic environments, it can start a phenomenon called eutrophication, which causes a series of changes in biological succession processes and strongly negative impacts on species’ biodiversity and wealth. In this context, this work aimed, from an extensive bibliographical review, to gather strategic and essential information related to phosphorus sustainability, provoking a reflection regarding scenarios that involve this indispensable nutrient, focusing on the current situation of the State of São Paulo, Brazil, an important case study, both for the Brazilian and international scenario, by a gathering of data on the current situation of two of the main watersheds in the corresponding region. Relevant technologies used for phosphorus removal in eutrophicated environments are also addressed. Finally, the possibility of reusing the nutrients present in eutrophicated water bodies as an alternative source of phosphate fertilizer for agriculture is demonstrated.

Rice (Oryza sativa L.) is the most important staple crop. Rice is a source of essential vitamins such as vitamin C and B6, carbohydrates and other nutrients such as selenium and phosphorous. About 90% of world’s rice are cultivated in Asia and Africa. China is the leading producer. It fulfills 70% income and nutrition needs of Asian population. Rice can be the potential solution to hunger and malnutrition, especially in poor, developing countries. The methods of rice growth are transplanting and cultivation media, grow in hydroponic condition and grow in soil. The production of rice is impacted by biotic stressors, which are present in a wide range of agro-climatic conditions around the world. Multiple diseases can be brought on by biotic pressures caused by climate change. To mitigate the impact of climate change and enhance rice cultivation unique germplasms are being cultivated. This review presents unique germplasm of rice and their cultivators, methods of rice cultivation, disadvantages of rice cultivation for research purpose and diseases that affect rice.

Pakistan produces enormous quantity of biomass wastes for example rice straw (RS) and rice husk (RH), wheat straw, and other biomass wastes that are being burned in the field after crop harvest to prepare the land for next crop. Biomass is known as potential energy source which can be effectively utilized as an alternative to fossil fuels. This study aims to assess the energy potential and gaseous pollutant emissions from rice residues such as RS and RH. The Energy potential of crop residues in Pakistan was obtained by considering the residual characteristics like residue to crop product ratio, moisture level and lower heating value of dry biomass was obtained from the South Asian countries. The mathematical models were defined for the assessment of amount of residues, available energy potential and emissions of gaseous pollutants. The estimated amount of rice residues is 10147.65 thousand tons dry biomass. The theoretical and available energy potential of the rice residues were estimated as 159219TJ, and 100,431TJ respectively. Based on dry matter fraction and proportion of crop residue burnt, the total amount of crop residue burnt for RS and RH were 1356.38 thousand tons and 307.7 thousand tons respectively. Total emissions from burning of rice residues were 1749.59, 27.639, 2.432, 1.265, 4.997, and 0.549 Gg for CO₂, CO, NO, NO₂, NOx, and SO₂ respectively. It was concluded that the crop residues generated in Pakistan can be effectively utilized as an alternative energy source, to reduce demand supply gap, reliance on fossils fuels and lower contribution in global warming.
