Most soybean cyst nematode (SCN) resistant varieties have the same source of resistance, PI88788. While has provided two decades of resistance to SCN, these microscopic parasites are adapting and finding a way around its resistance.
It starts with a clean and well-prepared planter. Take advantage of these chilly days of February to make sure your planter’s in top form. Consider these tips:

The Agriculture Department Economic Research Service recently released a report on tillage intensity and conservation cropping practices. Conservation tillage was used on a majority of wheat (67 percent), corn (65 percent), and soybeans (70 percent) acres.
Checking fields for Soybean cyst nematode (SCN) is best done in the fall prior to soils freezing, but wet weather has prevented many growers from collecting samples.
This season saw many weather challenges during soybean harvest. Wet and delayed harvest conditions contributed to lodging.
By 2030, it is estimated that 70 percent of all farmland will have changed hands within a two-decade period. A USDA report estimates that in the next 5 years alone, 10 percent of the country’s 911 million acres of farm land will be changing ownership.
Across the country in 2018, the average rate to rent cropland was $138 per acre, 2 percent higher than in 2017. According to USDA, Irrigated cropland rental rate per acre averaged $215, up from $212 in 2017.
Ideal composition of soil is 50 percent soil solids, 25 percent water and 25 percent air. Compaction results from the loss of pore space between soil particles. Soil structure is altered when forces such as harvest equipment traffic compresses soil.
Crops growing on boron deficient soils often just quit growing. Little was known about how Boron (B) supported crop growth until just the past few years.
Tar spot complex is a relatively new disease to U.S. corn producers. First identified in 2015, it rapidly took hold in many fields this year. Two types of fungi in tar spot complex produce different yield effects.
