While iron is the fourth most common element in the Earth’s crust and most soils contain abundant levels of it, many times naturally occurring iron is not found in the forms most readily available for plant uptake.
With higher fertilizer prices, it appears that many no-tillers are taking a closer look at how nutrients other than nitrogen, phosphorus and potassium can help keep no-till soybean yields at a high level.
Low soil pH and certain metals are causing glyphosate to release phosphorus from the soil, which is responsible for about 25% of dissolved reactive phosphorus runoff in the Maumee watershed.
Scientists now know that the increase in dissolved reactive phosphorus (DRP) runoff that’s been plaguing the western Lake Erie basin is mostly coming from farms located in the Maumee watershed.
Year after year, fertilizer is the big gorilla in the room when it comes to farm expenditures. In 2014, the readers of No-Till Farmer spent an average of $85,513 per farm to feed their crops — far outpacing the average of $69,732 spent on average, per farm, for land rent.
After nearly quitting on agriculture, Jonathan Cobb is rebuilding his family’s central Texas farm through no-till practices, intense cover-crop mixes and rotational grazing to amass ‘soil wealth.’
Less is proving more for Jonathan Cobb — fewer acres, lower expenses for equipment, fertilizers and herbicides and more hope about his future in farming.
Most problematic for legumes, molybdenum deficiencies are sometimes misdiagnosed as nitrogen deficiencies, but with a soil pH greater than 6.0, a response to applications is unlikely.
A Purdue University study shows that high-yielding, modern corn hybrids take up not only more nitrogen from soil but more micronutrients such as zinc, iron, manganese and copper. Nitrogen fertilizer rates also influence how much of these nutrients are stored in the grain at harvest.
