The cost of fertilizer has increased dramatically with the recent spike in energy costs. Today's fertilizer application cost $62.50 per acre, which represents the largest single-day expense we'll incur all season long. However, fertilizer application is still the best investment you can make in managing your pecans. Annual fertilizer applications increase pecan yield by over 600 lbs/ acre.
Come this fall, we will apply and additional 100 lbs of urea per acre (46 lbs. N/acre) sometime during the month of October. If fertilizer prices remain constant (which they won't), the fall nitrogen application would add $22.25/acre to our fertilizer costs. For the year, we will end up applying 115 lbs. N/acre and 60 lbs. K/ acre.
