Besides building healthy soil, living roots are the tool to fix marginal lands. Salt-affected soils are an example of a hard-to-fix marginal land situation in South Dakota. There are annual and perennial plants that can tolerate more soil salts

It has been hard for scientists to predict how much extra water farmers can expect when they use regenerative agriculture practices that improve soil carbon. This is important because many farmers consider water management to be the biggest reason to adopt soil health management practices like cover crops.

To help understand cover crop decomposition and N release throughout the growing season, University of Nebraska researchers designed a study using “litterbags” — a common method to research crop decomposition. This research is part of the Precision Sustainable Agriculture (PSA), a collaborative project supported by the Agriculture and Food Research Initiative’s Sustainable Agricultural System Coordinated Agricultural Projects from the United States Department of Agriculture (USDA).

Cover crops are typically used by producers in dryland no-till cropping systems to improve soil health, reduce soil compaction, enhance nutrient cycling, improve soil structure, and improve water infiltration. Producers may be able to realize some income from cover crops by grazing or haying them. But is this a good idea or will it cancel out any benefit the cover crops would otherwise have on soil properties and residue cover?

Two ongoing studies are measuring how much soil is being blown across different fields, and how much nutrients lost with wind erosion might cost farmers. Overall, preliminary data indicates that management makes a difference: leaving residue on a field or planting cover crops, and less aggressive tillage, can slow down soil movement.

In the past month, dust storms have been making headlines across the western United States. Blowing soil has created driving hazards due to low visibility, and accumulated wind-blown silt even forced boat ramp closures near Fort Pierre. The good news is that land can be managed to minimize erosion.
