With the extremely dry conditions, new article available @cropforageturf or https://t.co/IIWoDwdFsi may be of interest; Comparing N timing and sidedress placement strategies on corn growth and yield @TaylorPurucker

Nice job defending your #wheat and #beet MS thesis today @S_Purucker; You will be missed but many good things still to come!

One of the sometimes forgotten components of #wheat profitability that has paid many kids' college tuition is straw production; Our straw study appears off to a great start..even with the May snow flurries!

@MSUEFieldCrops Virtual Breakfast this morning, Dr Steinke @MSUSoilFert , "Growers often perceive yield loss as a larger risk than profit loss"

New article available @AgronomyJournal or https://t.co/IIWoDwdFsi on "#Soybean seeding rate and fertilizer effects on growth, partitioning, and yield"; grain yield and profitability should be considered along with soil nutrient concentrations for long term sustainability

Nitrogen is always the talk of the town for dry edible beans BUT don't forget about potassium! No K (left) vs 25 units K (right) with STK values just above critical; https://t.co/04Zwjst9IH

Thus far seeing a bit of additional stay-green potential with a late vegetative liquid potash app (left) vs. no app (right) under irrigation and at above critical soil test K values. Stay tuned.... @MichiganSoybean

Great week for #wheat planting; consider a starter fertilizer, especially if plant timely and low pre-plant soil NO3 values (<5 ppm); pictured left no autumn starter vs. with starter right (30N, 25S) at Feekes 7; all plots received P and response inconsistent above critical limit

New article from @MSUSoilFert "Comparing High and Low Input Management on Soybean Yield and Profitability in Michigan" now posted at https://t.co/IIWoDwdFsi or @cropforageturf Nice job @Quinn_Dan11 Thanks to @MichiganSoybean for the support

The power of soil fertility! Seeing some tremendous plant growth responses in low population soy thus far. Question remains whether yield and profitability follow? 60K pictured with zero inputs (left) and 2x2 with some in-season P, K, S (right) @MichiganSoybean

What an experience and learning opportunity! Thanks to @NutrienLTD for a great potash mine tour. The infrastructure and ingenuity were amazing; @MSU_PSM

Have we already left #corn yield in the field? 40 units N applied 2x2 with V4 sidedress (SD) (left) compared to 40 units N applied 2x2 with V11 SD soon to come (right); Regardless of SD preference, remember to give that plant enough N early to get it to your SD timing

With such a crazy spring, which corn N rate is optimal? Pictured left to right are 0, 50, 100, 150, 200, 250, and 300 units N at this point of the season. Stay tuned....

Time to bulk up! Starting to dig in and examine #potato early tuber set and biomass responses to phosphorus applications at all of our on-farm locations; next few weeks critical for tuber development; @MIPotatoes @MichDeptofAg @MSUAgBio

Seeing some fantastic #sugarbeet nutrient responses this year; Pictured are N only; N and P; and N, P, and S; Olsen P came back near 16 ppm so below critical @michigansugarco

After what seems like a monsoon of a spring, the heat and dry weather finally allowing us to fire up the irrigation for our @MichiganSoybean high intensity management study; stay tuned....

Don't Guess, Soil Test! When near critical soil test P (STP) concentrations, we have seen starter N drive an early season P deficiency (left) compared to no starter N (right); Know your critical STP concentrations!

Starter fertilizer already paying dividends on #sugarbeet; Same N rates below but lack of starter N (left) as compared to with starter N (right)

Finally seeing some nice separation in our #wheat nitrogen x fungicide x variety trials with @MartinChilvers1; 80 N left, 160 N right; Waiting to see if disease will follow...

Had to do a double take when walking across campus this morning. The lack of any one person on this mower mowing athletic fields really caught my eye! @MSU_PSM
