Agriculture in Brazil is a means for promoting significant socioeconomic sustainable progress. However, the productivity of cereal crops such as maize, rice, wheat and sorghum is below their potential. The low availability of phosphorus (P) and inadequate fertilization are some of the major challenges of modern agriculture. In tropical soil, the phosphorus is carried out by adding high dosages of water-soluble phosphates, since most of the added fertilizer becomes unavailable because of fixat ...Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2012 |

Precision farming and agricultural practices that take into consideration the protection of the environment have brought forward a number of research challenges. The scale of sampling and the precision required by such new agricultural practices are often higher than those required by traditional agriculture, increasing production costs. Methods and devices for on-the-go measurements are being developed to equip agricultural vehicles to support these practices. The proposed project was guided ...Status: Completed Start date: Mon Sep 01 00:00:00 GMT-03:00 2008 |
| Embrapa has built a highly conducive environment for the use of strategic and competitive intelligence to support action planning and scheduling and to provide important information to the different agents in the supply chains to which it relates. This is expressed in Embrapa's Agropensa (Strategic Intelligence System) dedicated to producing and disseminating knowledge and information in support of the formulation of research, development and innovation strategies for the corporation and its par Status: Completed Start date: Thu Jun 01 00:00:00 GMT-03:00 2017 |
| Bananas are one of Brazil's main agricultural products, having great economical significance. With a production reaching over five million tons annually, the fruit is a source of food for millions of people around the world. However, the plantations have been facing diseases and plagues which reduce the productive cycle once the local farmers are oblivious to certain agricultural practices. In the Amazon, the need to increase the crops is hindered by the lack of quality genetic strains for disse Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |
| The silvopastoral systems are a viable option to avoid degradation of pastures due to their potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to the pasture, improving soil fertility. However, an important aspect in these systems refers to the competition for light between the tree/shrub and herbaceous components. Tiller production and the consequent density of inflorescences, directly related to seed production and, therefore, to natural resee Status: Completed Start date: Wed Aug 01 00:00:00 GMT-03:00 2007 |
| Silvopastoral systems may be an option to prevent grassland degradation because of the potential to control erosion and the ability of some tree species to add nitrogen and other nutrients to pasture, improving soil fertility. In view of this potential, in-depth evaluations of the soil and plant components of these systems are critical. The objective of this project was to verify the effect of trees on soil quality (fertility, biomass and microbial activity) and to evaluate the dry matter produc Status: Completed Start date: Thu Mar 01 00:00:00 GMT-03:00 2007 |
| This project aims to propose viable technological alternatives for a competitive stockbreeding practice, making responsible use of the environment and regional resources and preserving the native flora and fauna of the Cerrado, Amazon and Pantanal. The beef cattle industry has an expressive social and economical role, being responsible for more than 6 million jobs and contributing with more than US$3 billion in the country's exportation activities. The Cerrado is currently the most important reg Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |
| The Extractive Reserve (Resex) "Forever Green" was created in 2004, in an area of 1,288,717 hectares in Porto de Moz- PA. The families that live in this reserve survive especially of artisan fishing, of subsistence agriculture and of raising domesticated buffalos. The region's income increase face the lack of technical knowledge and difficulty of direct access to the consumer market as main obstacles, point out locals. This project aims to organize and develop practices inside Resex with the int ... Status: Completed Start date: Thu Feb 01 00:00:00 GMT-03:00 2007 |
| The collared peccary ( Tayassu tajacu) are rustic and gregarious animals who provide meat and leather of excellent quality, being thus an important source of protein especially to the subsistence of the Amazon's needy population. The use of this animal is, however, being done without planned hunting, being thus associated with the destruction of their natural habitat and, consequently, the loss of these resources, which are scarcely known.

| The productive local set ups (APLs) of the Cupuacú tree represent how it is possible to develop agriculture with environmental and social responsibility. This is so because great part of the family farmers and small farmers set up their orchards in already deforested areas, in intercropping systems with temporary and permanent species, once the cupuaçú tree accepts moderate levels of shading. These orchard set ups try to emulate the forest environment, especially in the control of soil erosion a ... Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2007 |
