The Bulletin 100 System is an institutional program of the government of the state of São Paulo that has provided farmers with soil fertility management tools for best decisions for more than 40 years. This System is made up of a network of around 170 soil analysis laboratories and a publication organized by the Agronomic Institute (IAC): "Bulletin 100: fertilization and liming recommenda…
This proposal focuses on Brazilian agriculture potential to greenhouse gas emissions reduction and carbon sequestration, with emphasis in integrated production systems and sustainable management practices. To achieve this goal, two long-term field experiments of integrated crop-livestock-forest systems will be utilized. These experiments are pioneers in the state of São Paulo and have bee…

The intense mechanization of harvesting and planting occurred in the system of sugarcane production, arising from the completion of the burn, the soil subjected to strong compression, reducing root growth, reducing productivity and longevity and subjecting the soil erosion risk due to lower water infiltration into the soil. For these reasons, we study new systems of soil preparation and s…
In no tillage system the absence of soil mobilization consequently decreases plant residues accumulation and places fertilizers on surface, affecting the acidification process.Thus, it is necessary input application, especially materials for acidity correction.Improvements on physical, chemical and biological soil conditions occur with lime application that favor the production of biomass…

The present proposal will test whether Brazilian soils accept the C saturation hypothesis. Data from Embrapa will be used to estimate the organic carbon of the fraction associated with minerals (COAM) using a machine-learning Random Forest model. The COAM will be plotted as a function of the soil's silt+clay content. Testing this hypothesis is paramount to establish metrics regarding the …
Peanuts partially obtain nitrogen from N-fixing bacteria. However, its production in sugarcane renovation areas and degraded pastures faces serious challenges due to poor soil quality. This condition limits biological nitrogen fixation (BNF), which is vital for supplying nitrogen to peanut and other legumes. The efficiency of BNF is closely linked to the availability of elements such as n…
The increase in temperature caused by the high concentration of greenhouse gases (GHG) has a negative impact on food production by agriculture. Agriculture is one of the sectors that most contributes to the growth of the national gross domestic product, accounting for 21% of the total wealth produced. Global warming has been intensified by anthropogenic GHG emissions, among which CO2 is a…

Brazil is a major world producer of food, however, it is highly dependent on imported inputs, such as phosphate fertilizers, in order to meet the needs of the production system. An alternative to these fertilizers is the use of natural phosphate, which has shown great aptitude in the partial or total replacement of Monoammonium Phosphate (MAP) and other commonly used phosphate fertilizers…
The prospection of alternative sources of potassium fertilizers has become an imminent necessity in view of the rise in the prices of inputs, aggravated by the global situation of demand and possible crisis in the supply of these products. Enabling the use of national sources not only represents greater autonomy for national agriculture, but also allows for the exploration and use of more…
Brazil is a world leader in the food production in a sustainable way. However, most part of the inputs used in their agriculture come from imports, such as fertilizers, for example, which makes their acquisition expensive and difficult to access for farmers. A local alternative for these fertilizers is the use of ground silicate rocks, such as K-feldspar phonolite, a source of potassium, …

One of the primary challenges in using ground rocks as a nutrient source for plants is their relatively low solubility, which can limit crop yields. To address this issue, researchers have explored biological methods to enhance the solubilization of these minerals. In natural systems, plants, bacteria, and fungi play crucial roles in bioweathering, primarily through the secretion of low m…
This research is a continuation of a long-term cover-cropping experiment initiated in the 2006 season at Lageado Experimental Farm in Botucatu - SP. This is experiment part of the Global Long-Term Agricultural Experiment Network organized by Rothamsted Research. In tropical regions, crop rotation and cover crop adoption are necessary to increase soil organic matter (SOM) in conservation a…
The liming affects biological activities in the soil, and can to influence both the physical and chemistry of the soil and, thereby, changes crop growth and yields. Additionally, to use de lime, the gypsum use as a complementary practice can influence on root system development and resource availability. This changes the soil capacity to assembly the bacterial community and as to influenc…
