The Rural Voice, 1999-02, Page 27syndrome". These symptoms can be mistaken for herbicide injury or can be further aggravated by a pre - emerge herbicide under the right weather conditions, which I witnessed in several cases this past year. A three-year yield study in Pennsylvania, which Southeast Agway Co-op finished in 1997, actually showed best results from the 2" planting depth. Reconsider planting your headlands. I have had growers with combine yield monitors tell me that headlands can yield 60 bu. less than the field average. This is not profitable. Fine-tune your planting rates. Know which of your hybrids have lots of ear flex and will deliver 100% of their capability at 26-28,000, and which ones have a determinate car size that need a 30-31,000 population (stalk strength notwithstanding). You've probably heard about variable-rate seeding according to GPS and soil type. Don't spend any money chasing this dead horse! Fertilizer and nutrient management Sample soils and follow realistic recs and goals. Accurate soil tests allow you to skimp in years of tight money without hurting yields. It allows you to reduce fertilizer costs by taking advantage of the reserves you have put there. If you don't sample every three years you arc losing money. You're either applying too much or not enough. Rarely will you have guessed correctly, however I have seen it done more than once. Fertilize for realistic yield goals. A realistic yield goal is the average of the three highest yields from the past five production years for that crop in a given field. Apply most of your nitrogen in a sidcdress application if time and labour permits and base your rates on manure values and a pre-sidedress nitrate test if you are a livestock operator. I have been practising this procedure since 1991 and can honestly say it works every time. Reduce or eliminate phosphorous fertilizer applications. It looks like P has taken a big jump over last year. Additional P is not required for corn (beyond a nominal starter amount) or for soys, whcn P soil test levels are above 20 ppm on a bicarb test, or above 40 ppm on a Bray -P1 test. Additional P is not needed in wheat and alfalfa where the soil P levels arc above 25 ppm bicarb or 50 ppm Pl. Additional P will not produce a yield response in white or coloured beans when soil P levels exceed 20 ppm bicarb or 30 ppm P1. Apply micronutrients only where a response is predicted or known. Highly responsive crops will show a yield response to a specific micronutrient if the soil test is low. You've heard the stories on foliar fertilizer the past couple of years. Suffice it to say there has been more money wasted on foliars than have been gained on foliars. Take advantage of rotational benefits. Corn planted after soybeans yields 6 to 11% more than corn after corn. Corn planted after wheat over - seeded with red clover yields 10 to 18% higher than corn after corn. The red clover contributes 40 to 60 lbs. of actual N per acre. Longer rotations will reduce yield losses from insects, nematodes, white mold, and root rot. It's just too bad we can't make good money with wheat, oats and barley.
