Field history matters when trying to apply the optimal amount of nitrogen for sweet potato crops. Cover crops grown in the same plots prior to sweet potato crops affected how much nitrogen was needed.
One of the essential nutrients for vigorous crop production is nitrogen. Yet most routine tests done in commercial soil testing labs do not measure available nitrogen in the soil. Soil scientists think they have found a solution.
Weed management can be a tough challenge in organic cropping systems since growers don't have herbicides in their weed control arsenal. New research, though, shows that weather conditions and well-timed cultural management techniques can help fill the void by making crops more competitive.
Researchers explain the process of plant cooperation, in relation to their new study which has shed light on why cooperative relationships breakdown.
How do you boost soil water content and soil health without irrigating? Best cover it with a layer of straw, a new study concludes.
