Rice

Brazil is the largest producer and consumer of rice outside Asia.
It is one of the main foods in the Brazilian diet,
with high nutritional value.

RICE IN THE NATIONAL MARKET

The rice crop has wide adaptation to the soil, and has its planting in several regions of Brazil.

What do you need to know

Potassium and nitrogen fertilization along with micronutrients provide the nutrition necessary for rice farming to achieve greater productivity.

The rice crop is one of the main crops grown in the States of Rio Grande do Sul and Santa Catarina, however, other Brazilian regions have introduced this crop in their rotations, aiming at opening new agricultural areas, due to the resilience in aluminized soils producing in conditions rainfed, without flooding of agricultural areas.

In order to reach the highest productive levels of the crop, potassium and nitrogen fertilization are of paramount importance for rice farming, given the consumption of the crop, which follows an order of priority of extraction in the soil according to the following order: potassium (K ) > nitrogen (N) > calcium (Ca) > phosphorus (P) > sulfur (S) > magnesium (Mg).

Allied to the consumption of macronutrients are those of micronutrients that follow the following order of extraction: manganese (Mn) > iron (Fe) > zinc (Zn) > copper (Cu) > boron (B) > molybdenum (Mo). In order to meet the demand for nutrients balanced by the crop, Cibra has the fertilizer lines CibraMix, Nitrocap and BaseFort, which have the ideal requirement of nutrients to meet the needs of agricultural crops throughout the production cycle.
