Biochar and urea can be processed through a pellet mill to produce nitrogen (N) fertilizer pellets that can slowly release N to crop plants. This can increase N use efficiency to plants and reduce N loss to the environment. Illustration by Chumki Banik and Santanu Bakshi.

Top: drone image of a Michigan soybean field showing maturity progression based on planting date. Brown-colored strips represent early-season planting while yellow- and green-colored strips represent mid- and late-season plantings, respectively. Bottom: Soybean plants from plots planted at 124,000 to 519,000 seeds ha-1 (l to r, in increments of 99,000 seeds). These plants show the differences in plant architecture between seeding rate treatments. Photos by Maninder Singh/MSU.
