The soil is of vital importance for the planet. The soil is the main support of agriculture; for climate change, it is one of the regulating elements of the water cycle.
It is in this context that FAO and Embrapa signed an agreement, aimed at the operation of a digital soil mapping for Latin America, as part of the “support for the establishment of the second stage of the Latin American soil system” and whose results and products will be: a) Preparation of a package and program for capacity- ...

The program of genetic improvement of the cupuaçu tree ( Theobroma grandiflorum) needs to tend to the demand of new cultivares, especially of those resistant to the Monilophthora perniciosa fungus, the agent responsible for causing the deformity known as witch's broom disease, and also to increase as much as possible the genetic base of planting material. This project aims to develop new technologies which promote the quick multiplication of selected cultivares, as well as to early select ...

The total extension of the grasslands in Brazil still isn't quantified with precision, and even less are the degraded pastures. The demand for technologies that are able to quickly map and monitor the areas which are occupied with grasslands and their level of degradation, with precision and low costs, are ever growing. This research investigates the potential of the correlation between the data extracted from satellite images and data regarding grassland degradation obtained in field s

The quick diagnosis of diseases in plants that have economic value is essential to guarantee food security and avoid larger losses as a consequence of disease spreading. Two major problems may hinder this goal: 1) the permanent monitoring of all the plants by people capable of detecting diseases is mostly unviable; 2) in many cases, the person who detects the symptoms doesn't have enough knowledge to identify their causes. Despite the existance of solutions that explore technology as a facilitat

Diseases and pests which affect coffee plants are responsible for the reduction in coffee productivity and quality, and also raise production costs and the environmental risks resulting from the application of control measures. The indiscriminate use of agrochemicals also induce pest and disease resistance to control agents. A quick and precise diagnosis and a high or low risk alert for the accelerated progress and establishment of disease and pest epidemics, allied to wide and facilitated acces

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products

Soil quality may be measured through the use of indicators, which are attributes that measure or reflect the environmental state or condition of sustainability of the referred ecosystem. The knowledge regarding the spatial distribution of soil quality and its levels becomes essential in this case, once it favors the study of their relation with the type of soil management, with the environmental impact and the productive capability of agricultural systems. For such, it is important to have a met

Spectroscopy, which is always associated with chemometrics, is a versatile technique that is applied in several areas of science. It is fast, non-destructive, low-cost and, in addition, “clean”, requiring few or no reagents. The latter factor aligns the tool with green chemistry.

The current project aims to strengthen a multidisciplinary team that is familiar with spectroscopy, chemometrics, pedology, and soil fertility in order to adapt and incorporate various routine methods used in s ...
