José Lavres Junior graduated in Agricultural Engineering from the Luiz de Queiroz College of Agriculture (ESALQ) at the University of São Paulo (USP) in 1999. He obtained his Master's degree in Agronomy, with an emphasis on Soils and Plant Nutrition, from ESALQ-USP in 2002, and his Ph.D. in Sciences, focusing on Nuclear Energy in Agriculture and the Environment, from the Center for Nuclear Energy in Agriculture (CENA-USP) in 2007. He completed a postdoctoral fellowship with a CNPq scholarship at CENA-USP between June 2007 and June 2008, followed by a second postdoctoral fellowship funded by FAPESP from July 2008 to March 2010.Currently, he is an Assistant Professor (Ref. MS-3) under the Full-Time Dedication to Teaching and Research (RDIDP) regime at CENA-USP. He serves as a faculty member and accredited advisor in three graduate programs: Sciences (CENA-USP, CAPES rating 7), Soils and Plant Nutrition (ESALQ-USP, CAPES rating 7), and Forest Resources (ESALQ-USP, CAPES rating 6). His scientific research focuses on plant nutrition, plant physiology, and soil fertility, with an emphasis on the application of isotopic techniques (15N and 13C) to evaluate plant nutritional status, biological nitrogen fixation in soybeans, and nutrient and water use efficiency.Additionally, his research has advanced the understanding of nutritional physiology related to agricultural productivity, emphasizing nutrient uptake efficiency, ion absorption kinetics, and long-distance nutrient transport within plants. He is also involved in investigations into the physiological roles of nutrients in drought stress tolerance and the mechanisms for mitigating the impacts of stress caused by heavy metals. A growing research line includes the use of plant growth-promoting bacteria (bioinputs) as a strategy to enhance nutrient use efficiency, particularly nitrogen, significantly contributing to agricultural sustainability.This diverse set of research activities underscores his contribution to advancing scientific knowledge in key areas of sustainable agricultural management and adapting agricultural practices to contemporary challenges.

Cadmium (Cd) difficult the development of plants, whereupon can be minimized by sulfur (S) supply to plants grown in contaminated environments and the use of tolerant genotypes with high mass production for phytoremediation. The main objective is to evaluate the effect of S on the Cd uptake and its distribution on plant tissue, evaluate the ultra-structural changes on the root and leaves …

The most evident symptom of aluminum (Al) toxicity is the inhibition of root growth, which can be accompanied by anatomical damage to the xylem, reduced hydraulic conductivity of the roots (Lpr), increased lipid peroxidation, and suppression of aquaporin genes (AQPs). Furthermore, Al toxicity causes a reduction in stomatal conductance (gs), relative water content (RWC), and leaf water pot…
The low efficiency of nitrogen fertilizers is a global problem that hinders the sustainable development in agriculture and can generate risks to the environment and human health.The inoculation or co-inoculation of rhizobacteria that promote plant growth (PGPR) by multiple mechanisms has been considered a promising alternative in increasing the efficiency and recovery of nitrogen, but the…
There is a growing interest of the lumber market in the use of forest residues (e.g., stumps, harvest residues, and litter) for bioenergy production. However, more intensive management can result in the export of biomass and nutrients from the cultivation area, with the potential to cause erosive processes, reduction of biodiversity and the resilience of this environment, with negative im…

AAlthough there is a growing interest in the forestry sector in the use of forest residues for bioenergy production, this practice's intensive management exports biomass and nutrients from the cultivation area, causing erosive processes to occur, reducing biodiversity, and the environment's resilience capacity, in addition to generating other negative impacts on nutrient cycling, soil qua…
The stress caused by the water deficit can compromise the coffee tree's development. A plant strategy to minimize the effects of water deficit is potassium (K) retranslocation via phloem, altering drought resistance mechanisms. The aim of this study is to evaluate the dynamics of K retranslocation in coffee varieties subjected to water deficit conditions, correlating with gas exchange par…
Strategies to increase the efficiency of nitrogen fertilizers and benefit plant development and metabolism may reduce production cost and contribute to a more sustainable agriculture. To this end, the development of applied studies is necessary, especially for crops that occupy large areas, like grasslands. Our objective is to quantify the contribution of Herbaspirillum seropedicae inocul…

There is a rising interest within the timber industry in using forest residues, such as stumps, leaves, branches, bark, and litter, for bioenergy production. However, more intensive management has the potential to trigger erosive processes, reduce biodiversity, and compromise the environment's resilience, leading to negative impacts on soil quality (soil health), and thereby affecting the…
The poor efficiency of calcium-based foliar fertilization is mainly associated with the low Ca2+ mobility in the phloem of plants. Since most of the Ca reaches upper plants tissues through root-to-shoot uptake, its supply is strongly reduced as the xylem loses its functionality in sink regions, e.g., fruits, thereby inducing several Ca-related physiological disorders, such as blossom end-…
This project will evaluate and advance predictive modeling strategies associate with soil spectral libraries involving sensor data from X-ray fluorescence spectroscopy (XRF) and diffuse reflectance spectroscopy in the visible and near infrared regions (vis-NIR) for the diagnosis of tropical soil fertility. Essentially, three questions that comprise the state of the art for spectral librar…
Eucalyptus is a typical fast-growing hardwood, widely cultivated in tropical and subtropical regions where soils display low water and nutrients availability. Moreover, the increasingly severity and frequency of droughts may strengthen tree mortality worldwide. The xylem embolism consists in the blockage of the plant vascular system, being considered the major cause of plant death during …
