Key climatic characteristics of the main soybean producing regions of the United States and Argentin

1. The United States is mainly concentrated in the southwest of the Great Lakes region and its surrounding areas (Iowa, Illinois, Minnesota, and Indiana account for 44% of the country's soybean area and 48% of the production). It has a temperate continental climate, with a frost-free period of 160 200 days, high temperatures and humidity in spring and summer, and an annual precipitation of 520 650 mm; And the terrain is low and flat, fertile grassland chernozem, and the soil layer is deep, which is very conducive to the growth of soybeans.

2. Argentina is mainly concentrated in the three provinces of Santa Fe, Córdoba and Buenos Aires in the northeast (the output accounts for more than 90% of the country); Argentina has a largely temperate climate and has some of the richest farmland in the world, which makes Argentina's use of fertilizer per unit much lower than that of comparable countries. The natural conditions in Argentina are extremely suitable for soybean production, with easy access to high yields. Due to the favorable natural conditions, the unit material cost of soybeans in Argentina is much lower than in other countries.

Secondly, because Argentine soybeans are mainly produced in temperate regions, and its temperate climate conditions are very similar to those of the United States, it can quickly introduce American technology and directly use it, which greatly reduces its technology introduction or scientific research costs.

It is conducive to increasing the enthusiasm of the main grain-producing areas to focus on agriculture and grasping grain, and the peasant masses to grow grain and farm, and to stabilize domestic grain, the United States has expanded its soybean planting area by 10% this year, and it is possible to increase soybean production in Brazil and Argentina, which is estimated in 2008

There are some characteristics and differences between the various geographical regions of Brazil when it comes to soybean cultivation. Here are some of the characteristics of the soybean acreage in each geographical region of Brazil:

Midwest: The Midwest is Brazil's most dominant soybean growing region, accounting for about two-thirds of the country's acreage. The area has vast plains and abundant land resources, which are suitable for large-scale cultivation.

The main cultivation methods are large-area mechanized tillage and single-cropping, but there are also a small number of double-cropping. The main variety is genetically modified soybean.

South: Soybean acreage is also larger in the south, including Rio Grande, Santa Catarina, Paraná and Rio Grande do Sul. Compared with the areas of the central and western regions, this area pays more attention to the quality and diversity of planting.

Cultivation is diverse, including single and double cropping, as well as organic and non-GMO soybeans.

Northern Region: The Northern Region includes the states of Amazonas, Pará, Tucuma, and others. The soybean cultivation area in this area is small, but it is also suitable for soybean cultivation due to its abundant water resources and natural rainforest ecology.

However, the area is limited by the environment and policies, and most of the cultivation is based on traditional farming methods.

Northeast Region: The soybean planting area in the Northeast region is relatively small, mainly concentrated in Bahia, Ceará, Florida, etc. The land in the area is barren and rainfall is insufficient, making it less suitable for large-scale cultivation.

At the same time, soybeans grown in the region are mainly used in food processing and animal husbandry, which is not very important for soybean exports.

The main topography of the soybean producing region in Brazil is the plateau (the topographic area is the Brazilian Altiplano).

Tropical climate, Brazil's climate is dominated by a savannah climate, and soybean cultivation has a natural advantage.

Because of the low latitude here, there is plenty of light and heat, and the rain and heat are at the same time. There is an abundant source of irrigation water. The soil is fertile and has a high organic matter content.

The reason for this is mainly due to the fact that the latitudinal location is located at low latitudes, which forms a tropical climate. In addition, it is located in the Brazilian highlands, and the terrain is high and the temperature is relatively low at the same latitude, so it has a savannah climate.

Savannah climate, topographic influences (plateau topography).
