Get The Most From Foliar Feeding Corn And Soybeans

Enhancing the nutrient efficiency of plants through the leaves is not only possible, but profitable, with the right level of management.

Foliar feeding corn and soybeans remains a controversial subject in some corners of agriculture, but not to an increasing number of farmers who are using the practice to fine-tune fertilization strategies to maximize yields.

Finding The Fertility ‘Gold Mine’ After A Dry Year

No-tillers could save inputs costs and raise yields by accessing residual nutrients in fields, but they need relevant data and must understand the factors that affect nutrient availability.

Growers conducting soil tests this fall may be surprised at unexpectedly low potassium (K) levels,according to DuPont Pioneer agronomy experts.

Better No-Till Soils Require A ‘Balancing Act’

No-tillers should ensure farm ground is healthy and biologically active before turning to biological amendments, says a veteran no-till consultant.

When no-tillers are struggling to climb over a plateau in their crop yields, their first step should be finding out what’s happening with the nutrient balance and biological activity in their fields.

Corn Stover Removal And No-Till: A Balancing Act

No-tillers that follow guidelines can remove some stover from continuous-corn fields and still warm up soils, improve nitrogen efficiency and retain organic matter.

No-tillers growing continuous corn often face a dilemma when residue piles up in their fields after harvest, leaving a mat that can keep soils cold and wet and make planting difficult.

Fine-Tuning Fertility In A Quest For Top Yields

Pennsylvania no-tiller Dean James is focusing on secondary macronutrients, micronutrients and precision fertilizer applications to bring yields to the next level.

Plugging the lowest leak in the fertility barrel to boost yields and cut waste is the goal Dean James set for the 1,250-acre farm he manages. But achieving that goal requires creating a detailed fertility picture.

Increasing corn yield and harvest of cornstalks for feed, bedding or bioenergy production are generating numerous questions about phosphorus and potassium concentrations in cornstalks and removal.

A Winning Formula To Break Down Tough Residue

Agronomist says a mixture of 28%, Thio-Sul, humates, sugar and water can help digest today’s tough corn stalks for better corn yields the following year.

By Darrell Bruggink posted on December 1, 2011 | Posted in Nutrient Management, Residue Management

Corn residue has its good and bad points. It’s not so good if it interferes with no-till seed placement or crop emergence, but it’s a great source of food for soil biological activity and contains valuable nutrients for the next year’s crop.
