Brazil: 46.7% of the corn areas were sown in March

Fields analyzed in six states show that the soil moisture was below average at the sowing. 

We did an analysis of several areas in six states (Mato Grosso, Mato Grosso do Sul, Goiás, Minas Gerais, São Paulo and Paraná). The goal was to check the situation of the corn fields (second crop) and anticipate any problems. 

Through the analysis of the data, it was found that, in 73.2% of the areas, corn was planted with soil moisture below average, with emphasis on Paraná, where in almost 80% of the analyzed areas, the soil moisture was below average at planting. The survey shows that sowing in 46.7% of the areas in the six states occurred in March. 

Of the areas analyzed in Mato Grosso, 43.5% were sown in March, that is, outside the ideal planting window. In Goiás and Mato Grosso do Sul, 31.1% and 68.4% were sown in March, respectively. 

By the end of March, the emergence of corn was identified in only 56.1% of the sown area. 

In Mato Grosso do Sul, in 65% of the analyzed areas, the emergence had not been detected until the end of March, indicating that in these areas planting may have been done in the second half of the month. 

In the average of all areas, 43.9% the emergence has not been detected until the end of March. 

With the late planting of corn in this season, crops will be more exposed to less favorable climatic conditions, such as less solar radiation, less precipitation and higher possibility of frosts. 

Keep in mind that the corn germination may be delayed if the temperature and soil moisture are low and, for April, the forecast is for low temperatures and low rainfall at least until the middle of the second half of the month (Figure 1). Only in Mato Grosso do Sul and West Paraná, temperatures should be above average, but soil moisture should remain at a low level.

However, the american model (GFS) differs from the european model (ECMWF) and points to high level of precipitation in part of the corn area (Mato Grosso do Sul, Paraná, Mato Grosso and São Paulo). To monitor! 

The low levels of precipitation is to be concerned and should be monitored in the coming weeks. If the current scenario extends (drought and low soil moisture), the potential yields may be affected. 

Our production estimate is 79.87 million tons of corn in the winter crop, about 5.4% below that estimated by Conab (local source). 

With unfavorable climatic conditions, it is estimated that yield will be below the trend in all evaluated states (Mato Grosso, Mato Grosso do Sul, Goiás, Minas Gerais, São Paulo and Paraná). 

However the cycle is just at the beginning, so the estimates may change.
