Dry Weather & Nitrogen Prices
Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu; Wheat Conditions in Texas As you too well know conditions across most of Texas have gradually turned dry and worse into extreme drought (Fig. 1). For the northwest half of Texas winter is not the time we regularly get much moisture. Historically if wheat is established it can be pretty tough and can usually hang on until spring moisture comes, hopefully in time to take advantage of the burst of forage… Read More →

Dr. Calvin Trostle, Professor & Extension Agronomist/AgriLife State Hemp Specialist, TAMU Dept. of Soil & Crop Sciences, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu Dupont’s popular insecticide Prevathon is now a product of FMC.
