April transfers environmental news above the fold for Earth Month. North Carolina\u2019s climate and environmental challenges affect all citizens, but none more than the farmers who live and make their livelihoods from the land.\u00a0<\/span><\/p>\n

In a new Earth Day broadcast special, PBS NC examines natural solutions to carbon removal and carbon capture to mitigate North Carolina\u2019s evolving climate impacts. The in-depth special explores statewide environmental concerns told by the people they affect and the research addressing them, including two soil programs from NC State\u2019s Department of Crop and Soil Sciences.<\/span><\/p>\n

Preserving Coastal Farmland<\/span><\/h2>\n

Coastal North Carolina farmers have a unique relationship with water. Millenia underwater preserved the valuable carbon in their Blackland soils. Now, networks of drainage systems keep the sea at bay while the fertile land produces a large proportion of NC\u2019s agricultural crops. But the saltwater is intruding, impacting crop growth and reclaiming the soil.\u00a0<\/span><\/p>\n

Soil science researcher Matt Ricker heads an interdisciplinary team in the university\u2019s <\/span>Climate Adaptation through Agriculture and Soil Management<\/span><\/a> (CASM) group that is documenting and sourcing solutions to mitigate the profound effects of saltwater intrusion.<\/span><\/p>\n

\u201cMost of our coastal farmland is three to five feet above sea level, but some are as little as 18 inches above,\u201d Ricker said. \u201cProjections are for three feet of sea level rise by the year 2100. So you can imagine the impacts on this prime agricultural land.\u201d<\/span><\/p>\n

\u201cPrime agricultural soils have good soil structure held together by clays and organic matter,\u201d Ricker said. \u201cSalt in the system leads to loss of structure that reduces water movement and increases erosion and carbon losses.\u201d<\/span><\/p>\n

\"Soil

His group is pursuing a two-pronged approach to address saltwater-impact farmland: reclassification or remediation.\u00a0<\/span><\/p>\n

Farmland with prolonged, significant salinity (soluble salt index above 150) would be mapped and placed in conservation reserve programs. Expanding these wetland buffers can store carbon long-term and act as a sponge, absorbing saltwater and protecting productive nearby farmland. But the existing land use maps are over 60 years old and significantly outdated on this issue. Ricker\u2019s group is working with the USDA-NRCS to update the system.<\/span><\/p>\n

Ricker calls this carbon defense a good farm offense.<\/span><\/p>\n

\u201cCarbon accumulation leads to building land. By locking up carbon in soil, you\u2019re actually increasing elevation and fighting sea level rise.\u201d<\/span><\/p>\n

Cropland with modest or episodic salinity (from storm events) can be remediated with minimal crop impact <\/span>if<\/span><\/i> mitigated quickly. Ricker\u2019s group is working to develop rapid-assessment soil kits that would help farmers perform on-farm soil tests with immediate results rather than waiting potentially weeks for lab results.\u00a0<\/span><\/p>\n

\u201cSome of these farmers have losses in the millions of dollars,\u201d Ricker said. \u201cThese are large farm family systems that are losing productivity on land that they have farmed traditionally for over 50 years. They have a desperate need for this information.\u201d<\/span><\/p>\n

The saltwater intrusion segment of \u201cState of Change: Natural Solutions\u201d is called <\/span>\u201cOf Salt and Soil\u201d<\/span><\/a> and features Hyde County Extension Agent Adrea Gibbs working with growers like Dawson Pugh, who farms on the saltwater frontlines.<\/span><\/p>\n

\u201cSaltwater intrusion is a problem, but we are here to provide solutions,\u201d Gibbs said. \u201cMy role in Extension is to connect farmers with unbiased research-based information from NC State and other land-grant institutions. We are coming together to find solutions for the farmer.\u201d<\/span><\/p>\n

Building More Carbon With Less Tillage<\/span><\/h2>\n

Carbon is the central player in climate discussions and soil health. Nutrient cycling in productive soils depends on carbon, but tillage can negatively impact this crop-producing powerhouse. Frequent, invasive tillage to prepare planting ground inverts the soil exposing subsurface carbon to erosion and accelerating greenhouse gas emissions.\u00a0<\/span><\/p>\n

But increasing droughts and concentrated storm events are causing some growers to reconsider traditional farming practices. To improve their soil productivity with less disturbance, some farmers employ low-till or no-till methods to reduce erosion, retain carbon, build soil biology and conserve soil moisture.\u00a0<\/span><\/p>\n

Fellow NC State CASM member and soil scientist Alex Woodley heads a <\/span>N.C. Plant Sciences Initiative<\/span><\/a> group assessing soil-based emissions and one of several soils faculty conducting long-term tillage experiments.<\/span><\/p>\n

\u201cOver the long term, when we till, we\u2019re slowly degrading the soil,\u201d Woodley said. \u201cWe\u2019re losing\u00a0 soil carbon and aggregates so that when rain does occur, it causes surface crusting that reduces water movement into the soil.\u201d<\/span><\/p>\n

The long-term tillage study at the Reidsville, NC, research station started in 1984. It compares the dramatic impacts of a gradient of tillage practices from invasive moldboard plowing to no-till planting.\u00a0<\/span><\/p>\n

Woodley says that growers can fundamentally change the direction of how their soils behave from simple management practices like no-till.<\/span><\/p>\n

\u201cIt takes centuries to build up topsoil. We\u2019ve seen topsoil savings of up to six inches from no-till practices at this site. The no-till plots also show higher yields and better resilience in drought conditions.\u201d<\/span><\/p>\n

Her family adopted conservation tillage and no-till in 2019 to seed their livestock pastures and row crops.<\/span><\/p>\n

\u201cAs a farmer, it\u2019s all about efficiency,\u201d Beverly Blackwell Bowen said. \u201cWe were able to build soil quality and cut down on fertilizer costs as a result of going with regenerative agriculture.\u201d<\/span><\/p>\n
