Cropland to Pastureland As discussed in part 2 of this series, many conventional cropping practices acidify the soil unnaturally quickly. The reasons vary, but common culprits include excessive N fertilizer use and the loss of organic matter. They carefully selected cover crop species that were tolerant to high pH soils.
Cover cropping involves planting crops with the intention of improving growing conditions rather than obtaining a harvest. Increase Yields More diverse rotations can boost cropyields and resilience. In turn, this led to an increase in yields. Farmers plant corn one year and soybeans the following year.
As with many eco initiatives, what was old is new again: Cover crops (or fallow season plantings; see more below) were first used during the Roman Empire as a way to boost the soil quality in vineyards. Cover cropping is a means of increasing soil fertility without chemicals. How do cover crops work?

One cause of self-inflicted soil acidification is the excess use of nitrogen fertilizers like ammonium sulfate and urea because two H + are released each time an ammonium (NH 4 + ) ion is converted to nitrate (NO 3 - ). 2 Nitrogen Source Fertilizer Analysis (N-P-K) Lime Required (lb CaCO 3 /lb N) Anhydrous ammonia 82-0-0 1.8
In recent years, there has been a growing interest in regenerative agriculture, a holistic approach to farming that seeks to restore and revitalize the land while improving cropyields and overall farm profitability. This means increased cropyields and reduced inputs like fertilizers and pesticides.
When striving to grow lush, healthy plants that produce favourable yields, soil nutrient quality must be high. It’s no secret that keeping soil ripe with fertile nutrients – such as nitrogen, potassium and phosphorus, requires effort and care. These high-performing products are developed to improve soil health.
By Chris Lent, NCAT Agriculture Specialist When I began to see how unique the growing conditions in my high tunnel are compared to open-field growing, I started to think differently about how to maintain soil health and manage soil fertility for high tunnel growing and season extension. These strategies start with soil testing.
Healthy soil can mean increased yields (and profits) as well as fewer inputs like fertilizer or pesticides. One common method is the traditional or sequential crop rotation, where different crops are grown in a planned sequence over a period of years. Soil health is a holistic measure of soil function.
His soybean and wheat crops were also impacted. But there was one crop that suffered less. “It It doesn’t take a whole lot of rain to make a good yield for the sorghum crop,” said Rendel, who plants about 1,000 acres of grain sorghum each year on his 5,000-acre farm. Last year, he averaged only 22 per acre.
Understanding your soil (loamy, clay, etc), the PH, and the other trace nutrients that are available in your soil is vital to growing healthy crops. Growth and Yield: Many types of grass are perennials and have regrowth ability. Combining different hay types, such as grass-legume mixes, can enhance forage quality and yield.
Prairie strips or other noncrop strips along fields also offer refugia for beneficial species or, depending on species used, can act as trap crops that lure pests away from a cashcrop. Rotating crops also significantly reduces pests and diseases.
One way to reduce agricultural chemicals is planting cover crops in the Fall after the cashcrop is harvested. Winter cover crops could mean using less fertilizer and herbicide in the Spring. The type of herbicide depends on which cover crop is used and the timing for spring planting.
It was the annual field day at The Mill , a popular Mid-Atlantic retailer of agricultural products including seeds, fertilizer, and pesticides. One stop showed off a soybean yield trial. Farmers use herbicides to kill weeds that they could otherwise till under and to kill cover crops before planting a cashcrop.
It works as both a cover crop and forage for the cattle, and it’s helping Bedtka build up organic matter in his soil. Corn requires lots of nitrogen, and it’s by far the most commonly used fertilizer in the United States. Southeastern Minnesota’s Olmsted County is a microcosm of agriculture’s dependence on nitrogen fertilizer.
With tobacco as his principal cashcrop, Arthur needed to purchase fertilizer before December and prepare the land for planting by February or March. A fast-growing and high-yield plant, hemp suppresses weeds, thrives without fertilizer and pesticides, and requires less water than many other crops.
A review from earlier this year found that only a third of published studies in which researchers compared fields that were cover-cropped with those that weren’t reported significant gains in soil carbon. And a study published last month illustrated one major reason why farmers may be reluctant to plant cover crops.
Overapplying readily available N can also interfere with the uptake of other nutrients and lead to yield drag and profit loss, just as underapplying can. High-salt fertilizers add insult to injury by inhibiting soil biology and creating osmotic stress in plants. We need to drill baby drill – with cover crops. This is nonsense.
Land use change is the thing that matters, and it’s the openness to change that the big guys exhibit that is going to make a dent in agricultural emissions, sequestrations, nutritional yield, and worker well-being.
Fertilizer, fuel, and labor costs increase every year, while prices hardly change. Linwood Scott III is a sixth-generation tobacco farmer who’s worried about the crop’s “razor-thin margin.” Tobacco companies set the prices, and if you don’t have what they want, Scott said, they “don’t want it at any price.” Photo by John West.
