Even though snow that comes with the onset of cool temperatures can be a nuisance for our daily activities, it can benefit a winter wheat crop a great deal.
Chemicals were one of the most expensive individual costs in soybean production, behind only to seed in the non-land cost category. The average cash-rent soybean production farms incurred a crop chemical cost of $39/ac in 2015, an 88% increase from 2010.
Winter wheat planting season is soon at hand. Questions often abound on the issue of fertilization rates, timing and placement. Over the years, a lot of research has focused on starter fertilizers or split-applying nitrogen (N) and other nutrients. In general, phosphorus placed with the seed has been shown to increase tillering and total grain yield. Nitrogen is more uncertain, due to the possibility of salt burn and the associated yield losses.
